How milk teeth change. Which milk teeth change in a child for permanent ones. The main causes of late fallout

By the age of 9, the child's upper and lower incisors erupt in the dentition, the first permanent molars. Milk teeth and molars are still present in the dentition. Permanent incisors are normally located in the dentition exactly without "protrusions" and "collapses" to the side.

By the age of 10, the process of root formation is completed. permanent teeth already erupted in the oral cavity (first molar, central and lateral incisors). These teeth are "stabilized" in the bone tissue.

At the age of 9-10, the roots of the 4th milk tooth (1st milk molar) are resorbed and replaced by the 4th permanent tooth (1st premolar), first on the upper and then on the lower jaws. From 10 to 12 years old, the roots of the 5th milk tooth (the 2nd milk molar) begin to dissolve and milk fang and their replacement by the 2nd premolar and permanent canine, respectively. The last to erupt is the permanent canine.

By the age of 12-13, the replacement of milk teeth with permanent ones is completed. There should be 24 teeth in the dentition: 12 in each jaw.

The child is 9 years old: his upper and lower permanent central and lateral incisors, first molars erupted. Dairy chewing teeth and the fangs are still motionless, although the resorption of their roots has already begun.

Typical problems.

NORMAL permanent incisors are located in the dentition "exactly" without "protrusions" and "collapses" to the side. This indicates a harmoniously flowing process of the physiological change of milk teeth to permanent ones.

If there was early removal milk teeth in children and, as a result, the displacement of permanent chewing teeth forward, there is a formation improper closure dentition and crowding of teeth appears in the area of ​​the frontal and chewing teeth.

A common problem in the period from 9 to 12 years is poor hygiene oral cavity, which is associated with the characteristics psychological development children. As a result, caries of "young" permanent teeth develops. Most often, the 6th chewing teeth (1st molars) are affected in the area of ​​​​fissures (natural depressions of the teeth located between the tubercles of the tooth).

Fissure caries, remaining unnoticed, develops rapidly and is quickly complicated by inflammation of the nerve of the tooth (pulpitis).

PHOTO: In a child, the lower permanent incisors erupted in the second row. In this situation, it is required to make room by removing mobile milk teeth in order to permanent teeth were able to take the correct position in the dental arch.

Treatment and prevention.

At the age of 9 - 12 years there is a "stabilization" and a decrease in the intensity of growth of the jaws. "Fixed" previously formed anomalies in the development of occlusion. By the age of 12, when there are no milk teeth left, orthodontic treatment in most cases (but not always) only possible with braces

CHILDREN WHO HAVE STARTED ORTHODONTIC TREATMENT AT AN EARLIER AGE AND WAS HELD ON ORTHODONTIC PLATES AND TRAINERS TO CREATE SPACE IN THE DENTAL ARCH, TREATMENT WITH BRACES IS QUICK AND WITHOUT REMOVAL OF PERMANENT TEETH.

BRACKETS CANNOT INCREASE THE SIZE OF THE JAW, SO IN ORDER TO "STRAIGHTEN" THE TEETH BY "SCRITCHING" THEM INTO THE AVAILABLE SPACE, IT IS FREQUENTLY NECESSARY TO REMOVE THE PERMANENT TEETH.

THIS IS WHY IT IS BETTER TO START ORTHODONTIC TREATMENT IF NECESSARY AS EARLY AS POSSIBLE.

To prevent the development of caries of chewing teeth in the area of ​​fissures, a procedure called fissure sealing is performed - closing fissures in order to prevent further plaque from getting stuck in them and developing caries in them.

For the prevention of sports injuries of the upper incisors and canines, it is recommended to manufacture an individual sports mouthguard made by a children's orthodontist.

At the end of the exciting and painful period of the eruption of the first incisors, the canines of the parents begin to worry about another problem, at what age, how, when the milk teeth in children change to permanent ones, what complications and difficulties may lie in wait on this segment of the life path.

Number of members

Knowing the approximate number corresponding to age periodization makes it possible to understand how many milk teeth fall out in children for the entire period allotted by nature for this.

Their presence can be independently calculated by subtracting the number 4 from the age (in months). Therefore, a baby can have 8 erupted milkmen per year (12 - 4). Of course, it is difficult to expect such accuracy in reality, each baby is individual. Therefore, he can demonstrate all twenty young teeth at two and a half, and at three years.

Change of teeth: the essence of the process

Milk teeth appear in children relatively a short time. Already by the age of six, their loss begins, due to the natural course of growing up. At normal flow gaps are formed, indicating the imminent onset milestone farewell. In this case, the permanent canines and incisors that come to replace will easily be placed in their rightful places.

Scheme of loss of milk teeth and eruption of permanent teeth

If gaps are not observed, difficulties may arise due to lack of space.

The process of changing types of teeth in the ideal course of events does not cause difficulties. The shallow root gradually resolves, which is accompanied by a pronounced wobble. Children actively help by constantly touching the tooth with their tongue and fingers. This often leads to the fact that the milkman falls out before his permanent counterpart hatches.

Approximate terms

In the theory of medicine, of course, patterns have been developed for the course of the entire process of changing teeth, given that it begins with the front incisor, which is lost at 5.5 ÷ 6 years. Further, a certain sequence can be traced, which makes it possible to understand at what age the milk teeth in children change to permanent ones. The scheme, up to what age the process of forming a permanent smile is stretched, demonstrates this clearly. It builds up like this:

  • 6 ÷ 7 years - central incisors mandible, first molars - lower and upper;
  • 7 ÷ 8 - upper central incisors, lower lateral incisors;
  • 8 ÷ 9 - lateral incisors upper jaw;
  • 9 ÷ 10 - fangs from below;
  • 10 ÷ 12 - premolars - the first simultaneously with the second on both jaws;
  • 11 ÷ 12 – upper fangs, second premolars from below;
  • 11 ÷ 13 - lower second molars;
  • 12 ÷ 13 - second molars on the upper jaw;
  • 18 ÷ 22 - "wisdom teeth" - do not appear in every person.

Such an algorithm is considered the norm, which allows it to become an approximate guideline that determines when, at what age, a child's milk teeth - fangs, incisors - change.

If any violations of the order are found, it is imperative to seek consulting help from a dentist.

Scheme - until what age do milk teeth change to permanent

Oral hygiene

To maintain the excellent condition of the enamel of the emerging permanent incisors, canines on long years need careful monitoring by parents for compliance with the child hygiene procedures. For morning and evening cleaning, varieties of brushes with soft bristles are selected that are not capable of damaging the gums.

Pastes are purchased recommended for children with structural formula calcium and fluorine. Children do not like lengthy procedures and without parental supervision may not be thorough enough. Therefore, control is necessary in order to form a habit. proper cleansing all dental surfaces.

An important component hygiene measures is rinsing the mouth with decoctions of herbs - chamomile, St. John's wort, yarrow, a weak saline solution or just water at the end of a meal. This simple and accessible method for a child, which has become a familiar ritual, will prevent Negative consequences in the form of inflammation, with the accumulation of plaque. Every six months it is advisable to visit the dentist even in the absence of visible violations.

Sometimes children's teeth, when they change, leave a bleeding hole. It is necessary to attach a piece of sterile bandage to it, which the child bites and holds for about ten minutes. With the duration of the appearance of blood for more than twenty minutes, it is imperative to get the help of a doctor. Eating stops for two hours immediately after the tooth falls out. The child must be aware of this and independently accept the right decision if there are no parents around at that moment. It is not necessary to consume excessively hot or cold foods, as well as sour or spicy foods during the day.

At what age, how when do children's milk teeth change to permanent ones?

The necessary vitamin and mineral complex, which contributes to the formation of healthy and strong enamel, the duration of the course intake, the frequency is determined by the doctor.

Violation of deadlines

The length of the period, determined by the natural course of the child's growing up for complete replacement temporary milkmen, long enough. They clearly show which teeth change in children, a diagram, photos that are presented on the site.

In some cases, however, violations appear, the cause of which can be consulted by a dentist. Most often, anxiety is caused when everything has already passed allowable terms, and there are no permanent analogues. Milkmen by this time can hold their positions, or they can already fall out. A survey radiograph prescribed by a doctor is capable of clarifying the picture. Analysis of the resulting image will reveal the stage of formation of all teeth.

The child will experience the most difficult discomfort when losing milk teeth, which makes chewing difficult. Parents should organize a complete diet prepare various types cereals, pureed soups and vegetable purees.

"Shark teeth" - the reasons for their appearance

In a normally proceeding process, a loosened baby tooth and helps him in this, growing up next, a permanent colleague. However, not all children follow the algorithm in full, and the real representative is in a hurry to appear before the milkman gives way to him.

It is especially alarming if, in a similar way, in parallel with not falling out temporary teeth a number of permanent analogues that have come to replace are erupted. It is this position, outwardly similar to the three-row jaws of a shark, that caused such a figurative name for the wrong course of replacement.

Timely rendered dental care in the form of the removal of belated milk teeth will avoid the manifestation of unaesthetic growth of permanent changers. If the teeth continue to grow crooked, you will need the help of an orthodontist who will select a special device to help prepare favorable conditions for further proper growth. The action of such a device expands the growing jaw, creating enough space for new teeth.

How many baby teeth fall out in children

They resort to the forced removal of a milk tooth and in a situation of serious inflammatory process on the gum, in the place of the begun rocking. You will need to see a doctor if the baby is hindered by the mobility of the incisor or canine, causing inconvenience and even pain when chewing.

Features of the change of molars milk teeth

Due to confusion with concepts and terms, many parents ask topical issues whether all milk teeth fall out in children. the roots change. Which are chewy and which are not. It should be noted that the word root is not synonymous with the concept of permanent. Root milk is a tooth, which is entrusted with the function of carrying out chewing movements. These include four milk jugs - the last in a row on both jaws.

When they appear, pain and other negative manifestations. During the change to permanent types of problems, if they are observed, they are not so acute. little pain, local inflammation, low temperatures pass quickly enough.

Factors affecting tooth stability

The stability of permanent teeth required for long-term use depends on a number of factors:

  • heredity;
  • conditions for laying rudimentary dental tissues;
  • correct formation of primordia;
  • inflammatory processes;
  • milkman injuries;
  • compliance with hygiene procedures;
  • complete diet.

Causes of misalignment of permanent teeth

The sometimes observed crooked arrangement of growing incisors is explained by the fact that they did not have enough space, since their milk predecessors did not part in a timely manner, and there were no gaps between them.

When are milk teeth replaced by permanent teeth?

The reason for the growth permanent species in a crooked direction, there may also be bad habits, consisting in the developed constant sucking of a finger, tongue, or any objects. Corrective measures are appointed only by a specialist, who must be contacted immediately when negative situations are identified.

Sometimes parents have a question - the 5th tooth is milk or permanent, since it appears quite late. It must be understood that the fifth molar in a row is the last milk representative. If redness begins behind it, the gum swells, then these are manifestations of the imminent appearance of the sixth tooth, which will settle for life, as it is permanent.

Modern dentistry has such an innovative arsenal of techniques that it is able to level almost all the deviations observed when changing teeth in children. It is important not to miss favorable terms by visiting a medical institution in a timely manner.

At the age of three, the child already has all 20 milk teeth in his mouth. Some of the kids can boast of such an achievement at 2 years old, someone at 2.5, but very rarely the process of teething drags on longer than the indicated age. After all the milk teeth have come out, a calm period begins - painful, and often it happens just like that, teething is over.

When do children's teeth change to permanent ones?

But by the age of five, five and a half, it begins new period: milk teeth are loosened to give way to permanent, so-called indigenous. And there are more of them than milk ones - plus two pairs of chewing dental units grow in the child's mouth, in total 28 teeth, already permanent, will appear by the age of 12-13.

Change of milk teeth

And those “wisdom teeth” will erupt later. Although far from all people they grow: the last four can forever remain as the rudiments of dental units in the gums.

When to expect a change of teeth in a child

The teeth begin to change at the age of 5-6, it is at this age that the first molars erupt. From the age of five, the roots of the front incisors begin to dissolve in the baby, and then, a little later, the roots of the lateral incisors. And somewhere in 6-7 years, the first molars change. These changes take two years.

Eights or wisdom teeth

Not everyone grows

It turns out that the change of teeth lasts a long time, several years. And not everyone does this strictly according to the norm. Most children under the age of 13 have had all their milk teeth replaced, and only then do wisdom teeth begin (or do not begin) to grow. But it may happen that 28 permanent teeth will appear in a child only by the age of 16-17.

Why does a person change teeth at all

Any age-related changes logical, have a strict explanation. Nature and evolution wisely provide physiological factors requiring changes in the body. A person is born without teeth at all - he does not need them, since for the first months of his life he eats only liquid food, mother's milk. But already before birth, teeth begin to form in the jaw of the fetus.

First milk teeth

The first milk teeth appear in an infant at the age of six months (maybe a little earlier or a little later): at this time he is ready to chew already solid food. Chewing teeth grow by 2-2.5 years, by 3 years the baby has all the milk teeth in the mouth.

Milk teeth in children

But as a person grows older, the size of his jaw grows. In childhood, only 20 teeth fit in it, and by the age of 15, for example, a child needs 28-32 teeth to fully chew food. It is also worth understanding that the grown milk dental units do not increase in size, the distance between them simply increases.

How do the roots of children's teeth dissolve?

When the period of change of milk teeth to permanent ones comes, the first ones partially begin to dissolve. An important process starts from the top of the root, and then moves on to other parts of the dental unit. The densest part of the milk tooth, called the crown, is simply forced out by the permanent tooth growing right under it, and falls out on its own.

Features of the dental change process:

  • at three years and later, small gaps appear between the baby's milk teeth, they are called diastemas, and three are formed between the canines and the first molars;
  • the gaps may differ in size, they grow with age, and reach their limit by the time the milk teeth fall out;
  • the reason for the formation of gaps is directly the growth of the child's jaw, therefore these gaps ensure the normal development of the jaws;
  • if there are no gaps, this is a violation of the development and growth of the jaws.

diastema, trema

Is it normal for children to have gaps between their teeth?

Permanent teeth, meanwhile, are hidden in special connecting capsules. During the eruption period, they move directly under the roots of the first, milk teeth. All this can be seen on orthopantograms (the so-called panoramic shots) children 7-11 years old.

Do milk teeth need to be removed?

Dentists resort to the extraction of milk teeth in a very rare cases. Even severe caries damage is not an indication for removal. A milk tooth performs a number of functions, therefore it must perform its work in full, up to the moment of change to a permanent one.

However, if the damaged baby tooth is associated severe inflammation the tooth will have to be removed. Sometimes extraction (removal) of a child's milk tooth is required if it inhibits the growth of a permanent one. Or the permanent dental unit has already erupted, and the milk unit will not fall out in any way - then it has to be removed.

Extraction of teeth in children

If the milk tooth is removed ahead of time, the free space will be occupied by neighboring dental units. It turns out that the milk tooth saves space for the permanent tooth, that is, it is responsible for the norms of formation and growth of already permanent teeth. And if, for one reason or another, a milk tooth is removed, problems with the eruption of a permanent one are not ruled out.

A prematurely lost milk tooth is a unit that was removed more than a year before the eruption of an already permanent unit. This is fraught not only malocclusion. Missing teeth negatively affect the natural development of the jaw, and this is already a threat of deformation of the entire dentition. Therefore, doctors advise keeping milk teeth permanent until they are replaced.

Missing teeth adversely affect the natural development of the jaw

If the milk teeth are lost due to trauma, there is a children's prosthesis. it necessary measure: it is important that the entire dentition does not move, and the subsequent eruption of permanent teeth is physiological and absolutely normal.

Causes of misalignment of permanent teeth

Sometimes you can notice that the growing permanent incisors are not very nicely located. This is explained by the fact that during their growth, the teeth simply lacked space. That is, there were no special, anatomically necessary gaps between the predecessors of these teeth.

But the reason for the growth of crooked teeth may lie not only in this. Bad habits of the child will also affect the aesthetics of the smile. This is a pencil in the mouth, and biting nails, and the habit of biting inner surface cheeks.

Do not take any corrective action on your own. Only the intervention of a specialist can correct the situation. As soon as a defect is found, take the child to the dentist.

Tips for parents: what to do so that the change of teeth of the child is healthy and successful

There is nothing more important than oral hygiene, which the baby should be familiar with from early childhood. Of course, the list of mandatory dental care includes the formation of a healthy eating behavior. If parents doubt the choice of paste and brush for the baby, then you can find answers to all questions at a consultation with a dentist.

Tips for parents:


Do not rush nature - a tooth can stagger for a long time before it falls out and gives way to a permanent one. If the child does not interfere in any way, then nothing needs to be done. Do not look for defects where they simply do not exist: the first two teeth that have changed may seem crooked to parents. But this is an erroneous view, until the neighboring ones change, it is premature to talk about curvature. True, strong defects are noticeable, they require urgent intervention by a specialist.

What is fissure sealing

It is impossible not to mention such a popular modern dental service like fissure sealants. It concerns precisely the change of teeth, and they make it for permanent chewing teeth that have changed, and for milk teeth too.

A fissure is a cut in chewing surface root tooth. The cut is deep or not very dissecting the enamel of the dental unit. Fissure is translated from Latin - a gap. But such a gap is dangerous because it can anticipate caries. The slit-like shape of the recess contributes to the accumulation of food debris in it, which then rot, become the bait of pathogenic bacteria.

It is impossible to completely level the surface of the chewing tooth - this contradicts the very anatomy of the unit. But it is possible to fill such a “gully” in the tooth only partially with a substance that will prevent caries from hitting the tooth.

Only healthy fissures are sealed, if caries has already appeared, then first you need to clean the tooth to healthy tissues. It is desirable to seal milk chewing teeth.

Fissure sealing

How is the sealing of milk teeth

  1. The surface of the tooth is first cleaned of plaque, then dried and freed from saliva.
  2. The fissures themselves are treated with a special solution of phosphoric acid.
  3. After washing the recesses with distilled water, they are filled with liquid sealant.
  4. With the help of a special light-curing lamp, the sealant material is cured.
  5. Then the excess sealant is removed, the "sealed" tooth is polished.

This procedure is completely painless, it takes at least 5, maximum 45 minutes. In this way, the treated tooth is protected from carious lesion for 5-10 years. It turns out that children's teeth will be under reliable protection before changing to permanent. Permanent dental units can also be sealed in this way. This method is harmless, modern, highly effective.

Invasive fissure sealing

Dental health is a huge contribution to the health of the body as a whole. Children's teeth are the responsibility of parents. It is important not only to teach a child to care for teeth, to form a culture of nutrition, a negative attitude towards bad habits. It is also necessary to give an idea of timely handling to the doctor, a child from an early age should adequately relate to visiting the dentist. And it depends on the frequency of trips to the doctor.

If every six months a child visits a dentist (preferably has his own permanent doctor), his fear of the dental office will disappear. And he will continue to come to the doctor in the future with any problem or without it at all, just for prevention. Then all pathologies, diseases will be detected as early as possible, and, therefore, corrected and cured quickly and easily.

Don't forget to visit the dentist

The process of replacing milk teeth with permanent teeth good reason visit the dentist more often. Parents themselves will be calmer if so important process will be under the supervision of a specialist.

good decisions and healthy teeth you and your children!

Video - Change of milk teeth in children

Changing children's teeth is a difficult time through which, sooner or later, babies and their parents go through. A touching photo of a child with a toothless smile is in every family album. Usually, kids easily endure this period and even brag to their friends that their teeth have begun to fall out.

However, mothers still worry that their child is in pain, uncertainty, they try to reassure them that new teeth will appear soon. Many come up with stories about tooth fairies, bunnies and other fairy tale characters to make it easier for a child to get through a difficult time. You should not show too much emotionality, because you really need to worry only when problems arise during the change of milk teeth to permanent ones.

The main differences between milk teeth and permanent teeth

Molar teeth are replaced by milk teeth at 12-13 years. You should carefully monitor the timely removal of non-permanent ones. Moms are often interested in the question of how to determine which tooth is temporary or permanent. There are a number of distinctive characteristics of milk teeth:

  • they are smaller and taller, more rounded;
  • have a thickening of the enamel at the base;
  • there are no mamelons - mounds with jagged tubercles;
  • the edge of temporary incisors is even, molars - with tubercles;
  • located vertically (the crowns of the permanent ones are directed towards the cheeks);
  • quantity - 20 units (indigenous - 29-32);
  • fall out on their own with age (radicals are surgically removed).

The color of the tooth will also help resolve this issue. In milk teeth it is whitish-blue, in molars it is yellowish. In the absence of control over the loss of milk teeth in the future, incorrect bite formation is possible. You cannot pull them out on your own, even when the unit is staggering. It is important to wait until it falls out on its own, or contact a dentist. The specialist will carry out the procedure carefully with minimal trauma to the hole.

How does a baby tooth fall out?

Allotted for tooth loss certain time. Why is it important? They can no longer carry the chewing load and require replacement with stronger ones. The process has the following features:

  • permanent roots form in the alveolus near small milk roots;
  • resorption of non-permanent roots lasts up to two years;
  • the period of milk teeth, from when they begin to fall out - 4-7 years;
  • the process gradually affects the neck of the hard tissue, the incisors, milk non-permanent molars, canines change.

The process of changing milk teeth is symmetrical and has a sequence. Units swing on both sides of the jaw, and sometimes fall out without loosening at all. The fact that the process is going correctly is evidenced by the appearance of dental gaps by the age of five. This is a temporary cosmetic defect and the first sign of imminent loss of milk teeth. Their loosening passes without pain and bleeding from the gums.

The photo shows what a fallen milk tooth looks like in a person. It has a small crown and is distinguished by the absence of roots (they dissolve). Many parents worry about this, believing that the root has remained in the gum. This is not so - the root has resolved, however, in case of any doubts, it is better to see a dentist so that he dispels all fears.

The name of the teeth in children with a photo

Milk teeth play an important role in the development of a child. They are needed here:

  • help to chew solid food;
  • form bite and facial skeleton;
  • contribute proper development speech;
  • pave the way for eruption of molars.

From the photo and diagram of the jaw before the change, it can be seen that the dental units grow symmetrically, 10 on each jaw. The name and normal order of changing teeth is as follows:

  • incisors (front) - at 6-10 months;
  • incisors (lateral) - per year;
  • first dairy bottom and upper molars– 12-20 months;
  • eye (fangs) - 16-23 months;
  • milk second molars - 20-33 months.

A complete set of 20 milk teeth (their names are given above) comes out by 2.5-3 years. Partially, the eruption scheme is expressed by the formula: number of teeth = age in months minus 6. It is extremely rare for a child to have the rudiments of milk teeth. If none of them came out by the age of one and a half, it is important to show the baby to the dentist. The doctor will prescribe an X-ray of the jaw and determine the cause of the delay in eruption.

Table of the sequence of teeth falling out and replacing them with permanent ones

In children, all milk teeth are replaced. The time of their loss depends on many factors - this is heredity, the nature of the course of pregnancy, the type of feeding, the lack of vitamins and calcium, general state child's health. What time do the first teeth fall out? This is told by the graph and diagram of the loss of milk teeth. The process usually starts at 4-6 years of age. Girls have more early dates change of teeth.

In the same period, active resorption of milk roots occurs, the process can take up to 2 years. Milk teeth are gradually loosened, and under the pressure of a permanent unit, they are pushed out. The sequence of changing units roughly corresponds to their eruption.

What teeth change in children, and at what time? Front and rear are subject to change - each in its own time. The sequence is shown in the table (scheme of milk teeth):

Normally, an adult has 28-32 teeth. During life, 20 of them change, the rest grow indigenous. According to the schedule, the sequence of eruption of permanent units is as follows:
(more in the article: timing and pattern of teething in children)

To what extent are deviations from the schedule possible?

The period allotted for the change of dental units in children is quite long (more in the article: dental formula in children, eruption terms and table). The latter fall out at the age of 12-13 years. However, deadlines are missed and it is required additional examination at the dentist. Early loss at 4-5 years is possible as a result of trauma and carious lesions. If the process begins before the root unit has left, a void is formed in the row, where the remaining units gradually move. When the permanent one nevertheless begins to erupt, there will be no place for it, and it will grow crookedly.

Early loss of milk teeth is a reason to visit an orthodontist. Exist modern techniques prosthetics, with which you can replace the missing unit and avoid bite problems in adolescents. Such orthodontic treatment will cost much less than braces and caps in the future.

Another problem may be delay in eruption. This happens when the permanent teeth are ready to come out, but the milk teeth “sit” firmly. At the same time, defects in the dentition cannot be avoided. To prevent this, the removal of the milk unit in the dental office will allow.

It happens that the permanent teeth do not erupt at the set time, while the milk teeth have long fallen out. The causes of pathology in this case are:

When identifying the cause of deviations in eruption, the radiography of the jaw becomes of primary importance. When defects are found dental system held early prosthetics for the purpose of proper growth and development of the jaw, dentition. In adulthood, they are replaced with permanent prostheses.

Care tips after tooth loss

The change of teeth normally does not cause much concern for the children and their relatives. It is important to explain to the baby in an accessible form what is happening, and then he will not be afraid and complex. The temperature during this period does not exceed 37.5-38 degrees, it is not necessary to give antipyretics. More high performance talking about the accession of the infection. For pain, it is better to use gels that help with teething (Kalgel, Pansoral, Holisal).

When a milk tooth falls out, a hole remains, which sometimes bleeds. It is worth attaching a piece of sterile cotton wool to it and letting the child bite it.

After that, you should not eat and drink for 2 hours, exclude irritating dishes (sour, spicy) for the whole day. You can do rinses with herbs or a solution of propolis extract.

If a tooth has fallen out or this is going to happen, neither the child nor the parents should:

  • intentionally loosen and independently tear the dental unit;
  • chew on hard things;
  • pick your mouth with sharp implements;
  • treat the hole with alcohol, iodine and other alcohol-containing preparations (dentists categorically forbid).

Nutrition during the release of constant units should be rich in calcium, vitamins and trace elements. The children's menu should have cottage cheese and dairy products, solid raw vegetables, greens, fruits, liver, seafood. The child should be taught to healthy food, exclude abundant sweets, chips, crackers. This will reduce the likelihood of caries and prevent the development pathogenic microflora in the oral cavity. An important role is played by careful hygiene, the use of fluoride-containing pastes, high-quality brushes, rinses.

By 2-2.5 years, most children erupt all twenty milk teeth. After that, parents will have a calm period when no changes in the child's oral cavity occur. But after a few years, they begin to stagger and fall out one by one, making room for the indigenous ones. How exactly does this process take place and what is important for parents to take into account during the physiological change of teeth in children?

During the period of changing teeth, it is important to monitor the correct formation of the bite in the crumbs. How much does it change from dairy to indigenous?

All milk teeth, of which there are twenty, normally fall out, so that permanent ones appear in their place, which, for their strong long roots, are called indigenous. At the same time, more permanent teeth erupt than there were milk teeth, since babies have an additional 2 pairs of chewing teeth. As a result, in childhood, instead of 20 milk teeth, 28 permanent teeth erupt.

There should be 32 molars in total, but the last four may start to cut later, and in some people it does not appear at all, remaining in the form of rudiments in the gums.


Scheme: which ones and at what age change to permanent ones?

  1. The beginning of the shift is noted in most children at 5-6 years of age, when a child's first molars are cut. For their location in the dentition, they are called the "sixth tooth". At the same time, from the age of 5, the resorption of the roots of the milk incisors begins, a little later - the roots of the lateral incisors, and at 6-7 years - the roots of the first molars. This is a lengthy process, taking an average of 2 years.
  2. At 6-8 years old, the central incisors change in children. First, a pair located on the lower jaw falls out, after which, on average, at 6-7 years old, permanent incisors appear in their place, which differ big size and the presence of a wavy edge. A little later, the central incisors located on the upper jaw fall out. Average term eruption of permanent teeth in their place - 7-8 years.
  3. Next comes the period of change of the lateral incisors. On average, they fall out at the age of 7-8 - first the upper, and then on the lower jaw. Then the lower pair of permanent lateral incisors begins to erupt, and at 8-9 years old, similar teeth appear on the upper jaw. Also, at the age of 7-8 years, the process of resorption of the roots of the second molars and canines begins, which lasts an average of 3 years.
  4. The next to change are the "fours". They are called first molars, but after they fall out, which is on average noted at 9-11 years old, teeth “peck” in their place, which are called permanent first premolars. The first molars fall out first on the upper jaw, and then the turn comes lower teeth. However, permanent teeth in their place are in no hurry to erupt, giving way to fangs.
  5. At the age of 9-12 years, milk fangs fall out in children.- first the upper ones, popularly called " eye teeth”, and then the lower ones. Permanent fangs begin to be cut from the age of 9. The first such teeth appear on the lower jaw at the age of 9-10 years, and at the age of 10-11 years, the upper permanent canines also erupt.

    Between the ages of 10 and 12, a child's first premolars erupt at the same time.(fourth permanent teeth) and the second molars (fifth milk teeth) fall out, after which the second premolars (fifth permanent teeth) are cut. The last four milk cloves fall out first on the lower jaw, and then on the upper. After that, only permanent teeth remain in the child's mouth. The lower permanent “fours” appear on average at 10-11 years old, and in the period from 10 to 12 years old, premolars (fourth and fifth pairs of teeth) are cut in the upper jaw. At 11-12 years old, they are supplemented by the lower pair of second premolars.

    The second molars are cut last in childhood (on average from 11 to 13 years old) called "sevens". At the age of 11-12, they erupt on the lower jaw, and at the age of 12-13, the upper "sevens" appear.

    The third molars, also called “figure eights” or “wisdom teeth”, appear later than all other teeth. This is often observed at the age of 17 years.

Sometimes the root premolars erupt with milk teeth that have not yet fallen out.

Dialogue with S. Serbina, a pediatric orthodontist, see the video below:

Until how many years do they change?

The change of teeth in children lasts quite a long time, starting at 5-6 years. For some children, it ends before adolescence, but in most cases by the age of 16-17, only 28 permanent teeth erupt. Wisdom teeth erupt much later.

Are there any that don't change?

If we are talking about milk teeth, then they all change permanently. Some parents consider chewing teeth, which are the last to erupt in a child (“fours” and “fives”) permanent and think that they will not change. However, this is not the case, and the fourth, as well as the fifth milk tooth on each side of the jaw in all children should fall out, and in their place permanent ones appear, which are called "premolars".

All milk teeth of the crumbs will definitely be replaced by molars. Do molars change in children?

Since permanent teeth are called molars, which erupt in children to replace milk ones, then Normally, they shouldn't fall out. They remain with the children for the rest of their lives.

Oral hygiene during shift

While a child's teeth are changing, it is very important to carefully and regularly care for oral cavity, because the The enamel of new teeth is poorly mineralized and vulnerable to negative external influences.

The child should brush them twice a day with an age-appropriate toothbrush, as well as the right toothpaste. It is also advised to use special rinses and dental floss.

Oral hygiene should be mandatory procedure Morning and Bedtime Tips

  • In order for the teeth that erupt to replace milk teeth to be strong and healthy, it is important to pay attention to the child's diet in given period. The menu should have enough foods that have calcium and vitamin D. It is important to give your child solid food, such as apples or carrots, so that the teeth are cleaned and strengthened naturally during chewing.
  • You should not worry that by the age of 5-6 years, gaps appeared between the milk teeth. it normal process because the molars are larger and the baby's jaw grows to make room for them. On the contrary, if there are no intervals by this age, the child should be taken to the dentist.
  • Remember that the most common problem is tooth decay. Its occurrence is caused different factors among which hygiene and nutrition play an important role. Try to limit sugary foods in your child's menu and go to the doctor regularly with your child to identify this disease on early stages when it is not required to drill and seal teeth.

By protecting your baby from excessive consumption of sweets, you will keep his teeth healthy.

  • As a rule, permanent teeth are cut without pronounced pain. If the child is worried about pain, you can use an anesthetic gel used when teething, but it is best to go with your son or daughter to the doctor and make sure that the teething process is going well.
  • If the tooth is very loose, it can be pulled out at home. To do this, grab it with a piece of sterile gauze, shake it to the sides and pull it up or down. If it does not give in, postpone the procedure or go with the baby to the doctor.
  • Since the enamel of newly erupted teeth is not strong enough, The permanent teeth that appear first are often affected by caries."Sixes" are prone to this not only because of early eruption, but also because of the presence of fissures - depressions on the chewing surface, from which it is difficult to remove plaque. For protection, a procedure called fissure sealing is often used. If you want to perform it for your child, take the baby to the dentist as soon as the chewing surface of the sixth teeth is completely free of gums.


  • Remember that all the terms of falling out and eruption are averaged. For each individual child, they may differ, so with small deviations there is no reason to worry. If the loss of a tooth or the appearance of a permanent one in its place is very late, go to the dentist.
  • One of the most common problems of the shift period is the curvature of the erupting permanent teeth. If their position is not correct, take the child for a consultation with an orthodontist. Application special devices will help straighten them out.


Watch the transfer of Dr. Komarovsky.

At the age of three, the child already has all 20 milk teeth in his mouth. Some of the kids can boast of such an achievement at 2 years old, someone at 2.5, but very rarely the process of teething drags on longer than the indicated age. After all the milk teeth have come out, a calm period begins - painful, and often it happens just like that, teething is over.

But already by the age of five, five and a half years, a new period begins: milk teeth are loosened to give way to permanent ones, the so-called indigenous ones. And there are more of them than milk ones - plus two pairs of chewing dental units grow in the child's mouth, in total 28 teeth, already permanent, will appear by the age of 12-13.

And those “wisdom teeth” will erupt later. Although far from all people they grow: the last four can forever remain as the rudiments of dental units in the gums.

When to expect a change of teeth in a child

The teeth begin to change at the age of 5-6, it is at this age that the first molars erupt. From the age of five, the roots of the front incisors begin to dissolve in the baby, and then, a little later, the roots of the lateral incisors. And somewhere in 6-7 years, the first molars change. These changes take two years.

Not everyone grows

It turns out that the change of teeth lasts a long time, several years. And not everyone does this strictly according to the norm. Most children under the age of 13 have had all their milk teeth replaced, and only then do wisdom teeth begin (or do not begin) to grow. But it may happen that 28 permanent teeth will appear in a child only by the age of 16-17.

Why does a person change teeth at all

Any age-related changes are logical, have a strict explanation. Nature and evolution wisely foresee physiological factors that require changes on the part of the organism. A person is born without teeth at all - he does not need them, since for the first months of his life he eats only liquid food, mother's milk. But already before birth, teeth begin to form in the jaw of the fetus.

The first milk teeth appear in an infant at the age of six months (maybe a little earlier or a little later): at this time he is ready to chew solid food. Chewing teeth grow by 2-2.5 years, by 3 years the baby has all the milk teeth in the mouth.

But as a person grows older, the size of his jaw grows. In childhood, only 20 teeth fit in it, and by the age of 15, for example, a child needs 28-32 teeth to fully chew food. It is also worth understanding that the grown milk dental units do not increase in size, the distance between them simply increases.

How do the roots of children's teeth dissolve?

When the period of change of milk teeth to permanent ones comes, the first ones partially begin to dissolve. An important process starts from the top of the root, and then moves on to other parts of the dental unit. The densest part of the milk tooth, called the crown, is simply forced out by the permanent tooth growing right under it, and falls out on its own.

Features of the dental change process:

  • at three years and later, small gaps appear between the baby's milk teeth, they are called diastemas, and three are formed between the canines and the first molars;
  • the gaps may differ in size, they grow with age, and reach their limit by the time the milk teeth fall out;
  • the reason for the formation of gaps is directly the growth of the child's jaw, therefore these gaps ensure the normal development of the jaws;
  • if there are no gaps, this is a violation of the development and growth of the jaws.

Are gaps between teeth normal in children?

Permanent teeth, meanwhile, are hidden in special connecting capsules. During the eruption period, they move directly under the roots of the first, milk teeth. All this can be seen on orthopantograms (the so-called panoramic images) of children 7-11 years old.

Do milk teeth need to be removed?

Dentists resort to the removal of milk teeth in very rare cases. Even severe caries damage is not an indication for removal. A milk tooth performs a number of functions, therefore it must perform its work in full, up to the moment of change to a permanent one.

However, if severe inflammation is associated with the damaged milk tooth, the tooth will have to be extracted. Sometimes extraction (removal) of a child's milk tooth is required if it inhibits the growth of a permanent one. Or the permanent dental unit has already erupted, and the milk unit will not fall out in any way - then it has to be removed.

If the milk tooth is removed ahead of time, the free space will be occupied by neighboring dental units. It turns out that the milk tooth saves space for the permanent tooth, that is, it is responsible for the norms of formation and growth of already permanent teeth. And if, for one reason or another, a milk tooth is removed, problems with the eruption of a permanent one are not ruled out.

A prematurely lost milk tooth is a unit that was removed more than a year before the eruption of an already permanent unit. This is fraught with not only the wrong bite. Missing teeth negatively affect the natural development of the jaw, and this is already a threat of deformation of the entire dentition. Therefore, doctors advise keeping milk teeth permanent until they are replaced.

If the milk teeth are lost due to trauma, there is a children's prosthesis. This is a necessary measure: it is important that the entire dentition does not move, and the subsequent eruption of permanent teeth is physiological and absolutely normal.

Causes of misalignment of permanent teeth

Sometimes you can notice that the growing permanent incisors are not very nicely located. This is explained by the fact that during their growth, the teeth simply lacked space. That is, there were no special, anatomically necessary gaps between the predecessors of these teeth.

But the reason for the growth of crooked teeth may lie not only in this. Bad habits of the child will also affect the aesthetics of the smile. This is a pencil in the mouth, and biting off nails, and the habit of biting the inside of the cheek.

Do not take any corrective action on your own. Only the intervention of a specialist can correct the situation. As soon as a defect is found, take the child to the dentist.

Tips for parents: what to do so that the change of teeth of the child is healthy and successful

There is nothing more important than oral hygiene, which the baby should be familiar with from early childhood. Of course, the list of mandatory dental care includes the formation of a healthy eating behavior. If parents doubt the choice of paste and brush for the baby, then you can find answers to all questions at a consultation with a dentist.

Tips for parents:

  • in the years of changing teeth children's menu must include foods with vitamin D and, of course, calcium;

  • when the teeth change, the child should eat enough solid food - and these are carrots, radishes, apples, it is very important that the teeth are strengthened and cleaned by the most naturally too;

  • do not be afraid to see the gaps between the teeth of a five-six-year-old baby - the jaw is growing, and these gaps are necessary for healthy growth permanent teeth;

    The gap between the teeth in a child is not a reason to panic

  • do not let the carious lesion become the enemy of the child's teeth - reconsider your attitude to sweets, control the process of brushing your teeth, examine your child's teeth regularly (caries is easy to deal with at an early stage);

  • if the tooth is very loose, it interferes with the child, then you can pull it out at home - you need to clasp the tooth with a fragment of sterile gauze, then shake it in different directions, pull it up and down a little (but if it doesn’t help, consult a doctor);

  • do not forget about the averageness of all norms - small deviations from the timing of the change of teeth do not mean that something is wrong with your child;
  • timely detect the curvature of permanent teeth during growth, immediately contact a pediatric orthodontist.

Do not rush nature - a tooth can stagger for a long time before it falls out and gives way to a permanent one. If the child does not interfere in any way, then nothing needs to be done. Do not look for defects where they simply do not exist: the first two teeth that have changed may seem crooked to parents. But this is an erroneous view, until the neighboring ones change, it is premature to talk about curvature. True, strong defects are noticeable, they require urgent intervention by a specialist.

What is fissure sealing

It is impossible not to mention such a popular modern dental service as fissure sealing. It concerns precisely the change of teeth, and they make it for permanent chewing teeth that have changed, and for milk teeth too.

A fissure is a cut in the chewing surface of a molar tooth. The cut is deep or not very dissecting the enamel of the dental unit. Fissure is translated from Latin - a gap. But such a gap is dangerous because it can anticipate caries. The slit-like shape of the recess contributes to the accumulation of food debris in it, which then rot, become the bait of pathogenic bacteria.

It is impossible to completely level the surface of the chewing tooth - this contradicts the very anatomy of the unit. But it is possible to fill such a “gully” in the tooth only partially with a substance that will prevent caries from hitting the tooth.

Only healthy fissures are sealed, if caries has already appeared, then first you need to clean the tooth to healthy tissues. It is desirable to seal milk chewing teeth.

How is the sealing of milk teeth

  1. The surface of the tooth is first cleaned of plaque, then dried and freed from saliva.
  2. The fissures themselves are treated with a special solution of phosphoric acid.
  3. After washing the recesses with distilled water, they are filled with liquid sealant.
  4. With the help of a special light-curing lamp, the sealant material is cured.
  5. Then the excess sealant is removed, the "sealed" tooth is polished.

This procedure is completely painless, it takes at least 5, maximum 45 minutes. In this way, the treated tooth is protected from carious lesions for 5-10 years. It turns out that children's teeth will be under reliable protection until they are replaced with permanent ones. Permanent dental units can also be sealed in this way. This method is harmless, modern, highly effective.

Dental health is a huge contribution to the health of the body as a whole. Children's teeth are the responsibility of parents. It is important not only to teach a child to take care of his teeth, to form a culture of nutrition, a negative attitude towards bad habits. It is also necessary to give the concept of a timely visit to the doctor, a child from an early age should adequately relate to a visit to the dentist. And it depends on the frequency of trips to the doctor.

If every six months a child visits a dentist (preferably has his own permanent doctor), his fear of the dental office will disappear. And he will continue to come to the doctor in the future with any problem or without it at all, just for prevention. Then all pathologies, diseases will be detected as early as possible, and, therefore, corrected and cured quickly and easily.

The process of changing milk teeth to permanent ones is a good reason to visit the dentist more often. Parents themselves will be calmer if such an important process is under the control of a specialist.

Successful decisions and healthy teeth for you and your children!

In children aged 2-2.5 years, all milk teeth usually erupt, which is accompanied by unpleasant sensations for the baby. This is a difficult period, because parents are forced to look for all sorts of ways eliminate pain. After all 20 milk teeth erupt, a new period begins, more calm, since no changes occur in the child's mouth. But just a few years later, milk teeth, starting to loosen, gradually fall out, and molars appear instead. When do fangs, incisors and children change to permanent ones?

Eruption Features

All teeth are called molars, only they are still divided into permanent and milk. The latter gradually fall out when the child reaches a certain age, but parents do not need to worry about this, because the appearance of permanent teeth is not accompanied by painful sensations or discomfort. Unlike, the process can occur imperceptibly for the baby.

Parents should know how milk teeth are called in dentistry in order to understand when and how replacement takes place.

  1. molars. There are 12 of them in the oral cavity. AT dental practice they are called large molars.
  2. . Total at healthy person- 8 pieces, 4 on the lower and 4 on the upper jaw. The main task of premolars is to grind food during meals.
  3. . Unlike molars or premolars, there are not so many of them in the oral cavity - only 4 pieces, 2 each on the upper and lower jaws. The fangs are designed to tear off food particles.
  4. incisors. They are located next to the fangs, but only in more. There are 8 of them in total - 4 on the top and 4 on the bottom. The incisors are used for biting food.

There is a significant difference between the permanent dental arch and the milk arch, which, first of all, consists in different amount teeth. The milk arch consists of 8 molars, 4 canines and 8 incisors, located equally on the upper and lower jaws. Some parents are sure that the chewing teeth located in the back of the jaw do not change with age in babies, but this is not so. Dentists say that replacing milk teeth with permanent ones affects them too. Of course, this takes a certain amount of time. The baby's jaw must grow to the right sizes and then everything can fit in it.

When do children's teeth change?

The first milk tooth can fall out at any age, because each organism is individual. For someone, by the age of 4-5, only the incisor falls out, while for someone, half of the milk teeth will fall out by this age.

What does a milk tooth look like - photo

As practice shows, the molars develop quite quickly, pushing out the milk teeth in the process of eruption. It all depends on several factors, including the content of trace elements and calcium, as well as the characteristics of the body. But still there is a certain order of loss of milk teeth.

Table. Scheme for replacing teeth in children.

Name of the toothTiming of shedding and eruption
Initially, the incisors that are on the lower jaw fall out, and stronger and stronger ones grow in their place. big teeth. Permanent incisors differ from milk incisors in the presence of a wavy edge. As a rule, they appear at the age of 6. The central incisors fall out of the upper jaw a little later, and erupt at 7-8 years.
As a rule, they fall out at the age of 7 years - first of all, on the upper jaw, and then on the lower jaw. After that, the lower incisors erupt first, and at the age of 8-9 years, the upper ones grow.
The first molars fall out between the ages of 9 and 11, although in rare cases this may occur later. First, the upper molars fall out, and then the turn comes up to the lower jaw. Permanent teeth grow from the age of 12.
The fangs are popularly called eye teeth. First, the teeth fall out on the upper, and then on the lower jaw. This happens up to 9 years, and then permanent fangs begin to erupt. First, they grow on the lower jaw (at about 10 years old), and then on the upper jaw (at 10-11 years old).
At the age of 10, the baby's second molars begin to fall out and at the same time the first premolars erupt. After that, the second premolars grow. According to statistics, the lower premolars fall out first, and then the upper ones. The lower ones are cut at the age of 11 years, and the upper ones at about 11-12 years old.
AT children's period The second molars are the last to grow. This occurs between the ages of 11 and 13. As a rule, at 12 they cut through on the lower jaw, and at 13 - on the upper.
They are also called wisdom teeth. The third molars erupt after the rest of the permanent teeth already at the end childhood. It occurs at the age of 16-17 and most often in more adulthood molars have to be removed due to their abnormal growth.

Oral care when changing teeth

It is necessary to teach a child to personal hygiene from an early age, when milk teeth have just begun to erupt. To prevent problems with them in the future, you need to try to instill right habits since childhood. Encourage your child to brush their teeth at least twice a day after the first teeth appear. For this purpose, you cannot use the usual toothpaste for adults - buy a special children's brush and paste. The completion of each meal should be accompanied by rinsing the mouth. This can be done with the help of hand-made decoctions from medicinal plants. Also in stores are sold ready-made mouthwashes for children.

On a note! When the first symptoms appear, it is necessary to immediately engage in treatment. This will prevent spread to all permanent teeth. To do this, for the purpose of prevention, visit the dentist's office every 6 months.

The loss of milk teeth is an important period in the life of a child, because it is at this time that his permanent teeth grow, that is, those with which he will have to live his whole life. For this reason, parents are interested in the question: do all baby teeth change in babies and what do you need to know about this process?

Eruption and loss of milk teeth

The formation of the rudiments of milk teeth occurs even during the period of bearing a baby, approximately at the fifth month of pregnancy. They begin to erupt at the age of 4-6 months (later for some children), and by the age of three, babies already have a full set of teeth - 20 pieces. In their structure, milk teeth differ from permanent ones - their roots are slightly wider, since under them are the rudiments of permanent roots.

It is also quite difficult to name the exact time when it is - usually the process begins at 6-7 years and lasts for 6-9 years. There are a number of factors that influence this process, including:

  • genetic predisposition;
  • food and water quality;
  • the state of the immune system;
  • nature of the transferred diseases;
  • region of residence.

Thus, in healthy children who live in regions with high quality drinking water, permanent teeth grow faster, the process of changing is much easier. In general, fourteen-year-olds have all permanent teeth, but the chewing apparatus is considered to be fully formed only by the age of 20. It should be noted that these dates are very average - a deviation from the deadlines of 1-2 years is considered the norm.

Order of changing teeth

The change of milk teeth to permanent ones takes place in approximately the same order as eruption, but even here deviations are possible, which are considered a variant of the norm. Usually, the lower incisors fall out first in a child, after which the turn of the incisors comes from above. Over the next few years, the baby loses the lower incisors growing on the sides of the jaw, then the upper ones. Starting from the age of seven, the upper and lower molars fall out, then the canines come in the same order, and the last to fall out large molars. In some children, the canines and large molars change places, that is, the canines fall out last.

Table. Approximate age loss of milk teeth.

There is an opinion that absolutely all milk teeth in babies fall out and change, but in fact this is not entirely true. The structure of the children's jaw differs from the structure of the adult - if babies have only 20 teeth, then an adult has 32. The first permanent teeth that appear in a child are molars, or sixes. They erupt after the age of four behind the second milk molars and simply stand in line with the milk teeth.

The so-called baby teeth that should fall out are the lateral incisors, two pairs of molars, a pair of premolars, and canines. In addition, the child will grow 4 more additional teeth (second molars - sevens), that is, at the end of the process of loss, there will be 28 of them. lower teeth, as a rule, grow faster than the upper ones - an exception may be premolars. Eights - or wisdom teeth - grow already in adulthood, and in some people they remain in their infancy.

As in the case of milk teeth, the sequence and timing of the appearance of permanent teeth are individual and depend on a number of factors. But there is also one important nuance- too much fast loss milk teeth can cause the permanent ones to grow crooked, as a result of which the child's bite will deteriorate.

Table. Approximate age at which permanent teeth appear.

How is the process of changing teeth?

The process of changing teeth in the human body is laid down at the genetic level - for small children, twenty teeth are enough for high-quality chewing of food. After the age of five, the period begins active growth, the jaw increases, gaps appear between the milk teeth, which are subsequently filled with permanent teeth.

Unlike teething, the process of changing milk to permanent teeth does not cause discomfort to the child. The roots simply dissolve, after which the teeth fall out under the pressure of the “brothers” growing from below. A feature of newly grown permanent teeth is that they have an incompletely formed root - it takes about three years.

Despite the fact that in most cases the process does not require outside intervention, parents should keep it under strict control. Once a week, it is necessary to examine the child's oral cavity - from about the age of five, the baby's teeth seem to be thinning, and subsequently begin to stagger. Having noticed this phenomenon, you can begin to loosen your teeth a little so that they come out of the gums more easily.

  1. If a loose tooth gets in the way, you can pull it out yourself. To do this, wrap it with a piece of sterile gauze, gently swing it to the sides and pull it up. You should not make too much effort, otherwise you can inflict on the baby serious injury. If the tooth does not give in, it is better to leave it alone for a while or consult a dentist.

  2. Sometimes milk teeth sit firmly in the gum and interfere with the growth of permanent ones - in this case It is recommended to visit a doctor who will remove the tooth. If this is not done in a timely manner, the permanent tooth may grow incorrectly or “knock out” of the general row, due to which the bite will deteriorate in the child.
  3. Many parents are faced with such a phenomenon as caries of milk teeth. The decision to treat the disease should be made exclusively by a specialist (sometimes such a procedure is simply not advisable). It must be remembered that after filling milk teeth, their roots dissolve much more slowly.

  4. If after a tooth falls out of the wound there is blood, you should clamp the wound with a clean piece of bandage or cotton wool, and hold for several minutes. For two hours after the loss, it is better to exclude food, especially cold, hot, sour and salty foods.
  5. You can rinse your mouth after a tooth falls out, but not too actively - in the hole left in the place of the tooth, a blood clot which protects it from the ingress of microbes.
  6. If the change of teeth gives the child discomfort, you can buy a special toothpaste that eliminates discomfort.

  7. During the period of changing teeth, it is important to pay attention to caries and other dental diseases. If the milk tooth is affected carious process, there is a risk that his constant "brother" will also be sick. In addition, the child's nutrition at this time should be balanced, and contain enough vitamins and minerals, especially vitamin D and calcium. It is better to limit the amount of sugar and sweets so as not to create an environment favorable for the reproduction of bacteria. To cleanse and strengthen the teeth, you can give your child hard fruits and vegetables, such as apples or carrots.
  8. To protect a child's permanent teeth from negative impact, you should contact your dentist, who will carry out fluoridation of the teeth or sealing of fissures (protection of areas that are in hard-to-reach places).
  9. Even if the process of changing teeth is easy and without discomfort, the child should visit a doctor at least once every six months - this will help to identify caries in the early stages, as well as prevent its occurrence.
  10. If a permanent tooth has not appeared in place of the milk tooth within 3-4 months, parents should consult a dentist. The reason for this may be a rare pathology called adentia - the absence of rudiments of teeth. If the examination indicates this diagnosis, prosthetics will need to be performed to maintain a beautiful bite and shape of the face.

    Oral care when changing teeth

    During the period of change of milk teeth to permanent care behind the oral cavity plays a special role, since in soft tissues wounds are formed where the infection can get. To avoid infection of the gums and the inflammatory process, the child should rinse his mouth after each meal. For these purposes, you can buy special solutions at the pharmacy (for example,) or prepare a decoction of chamomile, sage, oak bark.

    To care for your teeth, you should use not only a brush and paste, but also dental floss, brush for teeth and other dental appliances. At proper care behind the oral cavity, the change of milk teeth will be absolutely painless, and permanent teeth will not become a source of problems for parents and the child.
