FAQ

First of all, one that does not hurt the gums during use. At the same time, the quality of hygiene oral cavity depends more on whether the teeth are brushed correctly than on the shape or type of toothbrush. Concerning electric brushes, then for ignorant people they are a more preferable option; although you can brush your teeth with a simple (manual) brush. In addition, a toothbrush alone is often not enough - flosses (special dental floss) should be used to clean between the teeth.

Rinses are optional hygiene products which effectively clean the entire oral cavity from harmful bacteria. All these tools can be divided into two large groups– treatment-and-prophylactic and hygienic.

The latter include rinsing agents that eliminate bad smell and promote fresh breath.

As for therapeutic and prophylactic, these include rinses that have anti-plaque / anti-inflammatory / anti-carious effects and help reduce the sensitivity of hard dental tissues. This is achieved due to the presence of different kind biologically active components. Therefore, the rinse aid must be selected for each specific person on an individual basis, as well as toothpaste. And since the product is not washed off with water, it only fixes the effect. active components pastes.

Such cleaning is completely safe for dental tissues and less traumatic. soft tissues oral cavity. The fact is that in dental clinics a special level of ultrasonic vibrations is selected, which affects the density of the stone, disrupts its structure and separates it from the enamel. In addition, in places where tissues are treated with an ultrasonic scaler (this is the name of the device for cleaning teeth), a special cavitation effect occurs (after all, oxygen molecules are released from water droplets, which enter the treatment zone and cool the tip of the instrument). Cell membranes pathogenic microorganisms are torn apart by these molecules, causing microbes to die.

It turns out that ultrasonic cleaning has a complex effect (provided that really high-quality equipment is used) both on the stone and on the microflora as a whole, cleaning it. Oh oh mechanical cleaning you won't say it. Furthermore, ultrasonic cleaning more pleasant for the patient and takes less time.

According to dentists, dental treatment should be carried out regardless of your position. Moreover, a pregnant woman is recommended to visit a dentist every one or two months, because, as you know, when carrying a baby, the teeth are significantly weakened, they suffer from a deficiency of phosphorus and calcium, and therefore the risk of caries or even tooth loss increases significantly. For the treatment of pregnant women, it is necessary to use harmless means anesthesia. The most suitable course of treatment should be selected exclusively by a qualified dentist, who will also prescribe the required preparations that strengthen tooth enamel.

Treating wisdom teeth is quite difficult due to their anatomical structure. However, qualified specialists successfully treat them. Wisdom teeth prosthetics are recommended when one (or more) neighboring tooth missing or it needs to be removed (if you also remove a wisdom tooth, then there will simply be nothing to chew on). In addition, the removal of a wisdom tooth is undesirable if it is located on the jaw in right place, has its own antagonist tooth and takes part in the chewing process. Also, one should take into account the fact that poor quality treatment can lead to serious complications.

Here, of course, much depends on the taste of the person. So, there are absolutely imperceptible systems attached to inside teeth (known as lingual), but there are also transparent ones. But the most popular are still metal braces having colored metal / elastic ligatures. It's really trendy!

Let's start with the fact that it's just unattractive. If this is not enough for you, we give the following argument - the stone and plaque on the teeth often provoke bad breath. And that's not enough for you? In this case, we move on: if the tartar "grows", this will inevitably lead to irritation and inflammation of the gums, that is, it will create favorable conditions for periodontitis (a disease in which periodontal pockets are formed, pus constantly flows out of them, and the teeth themselves become mobile). And this is already a direct path to loss healthy teeth. Moreover, the number of harmful bacteria at the same time increases, due to which there is an increased cariousness of the teeth.

The service life of an accustomed implant will be tens of years. According to statistics, at least 90 percent of implants function perfectly 10 years after installation, while the service life is on average 40 years. Tellingly, this period will depend both on the design of the product and on how carefully the patient takes care of it. That is why when cleaning without fail you need to use an irrigator. In addition, it is necessary to visit the dentist at least once a year. All these measures will significantly reduce the risk of implant loss.

Removal of a tooth cyst can be performed therapeutically either surgical method. In the second case we are talking about tooth extraction with further cleaning of the gums. In addition, there are those modern methods to save the tooth. This is, first of all, a cystectomy - quite complex operation, which consists in removing the cyst and the affected root tip. Another method is hemisection, in which the root and a fragment of the tooth above it are removed, after which it (part) is restored with a crown.

As for therapeutic treatment, then it consists in cleaning the cyst through the root canal. It is also a difficult option, especially not always effective. Which method to choose? This will be decided by the doctor together with the patient.

In the first case, teeth are used to change the color professional systems, which are based on carbamide peroxide or hydrogen peroxide. Obviously, it is better to give preference to professional bleaching.

Darkening and loss of transparency of the tooth can follow the loss of viability of the pulp of the tooth, both before and as a result of endodontic treatment. So in the case of an acute injury, internal hemorrhage into the dentin occurs. Other causes are infiltration of the dentin with toxins from the necrotic pulp, drug staining, cements, metal posts, or an optical effect due to dehydration of the tooth. When only one of the incisors is affected, most practitioners are reluctant to go down the path of making a full restoration of the tooth. Over a hundred years ago bleaching of discolored teeth was described, where Superoxol was mainly used at a concentration of 30% to 35%.

Superoxol is highly oxidizing and can cause soft tissue burns. The doctor and assistant must be extremely careful when working with liquid to avoid getting it on skin and the patient's mucosa. To initiate the release of oxygen, a heated Superoxol solution is introduced into the cavity of the tooth where endodontic treatment was performed. Oxygen breaks down dark pigmented macromolecules into smaller light-colored molecules. Alternative Treatment is as follows: wet cotton swab in a mixture of Superoxol and sodium perborate, then place it in the tooth cavity and close tightly with a sealed filling for 4-7 days. This method is called "home whitening". The previously used technique of internal devital bleaching was based on the use of 30% hydrogen peroxide (namely Superoxol) and at the same time the resorption of the roots of the teeth in the cervical region ranged from 6% to 8%, in the case of combining the introduction of the material with its subsequent heating, the complication rate increased from 18 % up to 25%. The cause of external resorption of the root of a bleached tooth, as described above, is complex.

Internal whitening technique

Along with careful selection clinical cases internal bleaching remains an excellent treatment option.

Perform a clinical and radiographic examination of the tooth using all the usual additional diagnostic tools to determine the need for retreatment of the tooth.

In order to record the original shade, take an intraoral photograph of the tooth to be bleached with an appropriate sample of the original tooth shade on the ceramic shade chart, placed in close proximity to the tooth.

Spend preventive treatment selected tooth and adjacent teeth.

Probe around the tooth to determine the contour of the CEJ line. Apply rubber dam (including near standing teeth for color comparison) and the tooth to be whitened fix with flux at the level of the gingival margin. Prepare access to the cavity of the tooth. Remove all endodontic filling material, paste, cement and the necessary part of the restorative material, while the amount of dentin removed should be optimal. Ensure that all residual pulp and organic material (common sources of discoloration) is removed from the coronal pulp chamber. Remove 2-3 mm of filling material from the upper third of the root canal.

Rinse the prepared access to the tooth cavity with a small stream of water and dry well without dehydration.

Enter the compomer into the root canal and tooth cavity (in Centrix syringes or using a canal filler). Position the insulating pad so that it follows the contour of the cement-enamel joint (CEJ) line and is 1 mm higher than it. The thickness of the insulating material must be at least 2 mm.

Place a cotton swab on the inner lingual surface of the tooth. Using a syringe with a metal needle, carefully inject Superoxol into the prepared cavity.

Using a dry endodontic spreader or whitening stick (in its lower or middle part), heat the solution to no more than 15 degrees Fahrenheit above body temperature. Repeat if necessary.

Rinse the tooth under running water. Place a clean, dry cotton swab into the cavity of the tooth and cover with temporary filling material - Cavit.

Photograph the tooth with the corresponding color sample on the color chart.

Reschedule the patient one week later and note the discoloration after saturating the tooth with water.

Repeat the procedure if necessary. When the desired color is achieved, the tooth is filled with glass ionomer cement.

The patient is scheduled 2 weeks later for a permanent restoration. This will level out the residual oxygen, which is very important and prevent it. bad influence on adhesive materials.

home whitening technique

If the result is not achieved during internal bleaching in the dentist's chair, the technique home whitening recommended as additional method. For many years this method has been the most popular among dentists.

With careful selection of clinical cases, the home whitening technique remains quite successful to this day. Depending on the severity of the residual discoloration and the age of the patient, the physician should also use a mixture of sodium perborate and Superoxyl in addition to sodium perborate and water. Most cases of external root resorption occur in patients under 25 years of age. There is an assumption that young people have more wide dentinal tubules than older patients.

Acid etching of dentin opens the lumen of the dentinal tubules, thereby allowing penetration more bleaching agent (increasing the risk of pore resorption). Acid etching of dentine does not increase the effectiveness of teeth whitening and should therefore not be performed.

The doctor must introduce a whitening paste into the cavity and to prevent micropermeability, the tooth must be covered with a thick layer (at least 2 mm) of a temporary filling such as Cavit.

The mixture should be left in the cavity of the tooth for up to one week. The patient is warned that when the tooth becomes lighter, he should immediately visit a doctor. This procedure may be repeated several times.

The bleaching agent has short period action and its effectiveness is reduced by 50% after 6 months.

The tactics of setting the final restoration was described above.

Note that increasing the amount of bleaching agent increases the risk of cervical root resorption, which can be minimized with a well-placed insulating pad. It has been noted that teeth after whitening are less resistant to fractures.

Repeated visits to the doctor

The manifestation of signs of resorption of the tooth root is not always detected in the next 6 months after the whitening procedure. Teeth that show damage after 2 years can, in principle, be preserved. Early definition and elimination pathological changes significantly improves the prognosis.

Repair of resorptive lesions in the cervical region

Sometimes the use of calcium hydroxide helps to stop resorption on initial stage. In most complex cases, orthodontic traction or coronal lengthening may be required to access the lesion and prevent biological width disturbance.

Often in cases where aesthetics is not a primary concern, silver amalgam is the simplest and preferred material. Composite materials are used to perform the most esthetic restorations. When the quality of the restoration depends solely on adhesion to dentin, the long-term prognosis is poorer.

Dumfahrt and Moschen described a technique for repairing a resorptive lesion in the cervical region of a tooth using an indirect ceramic inlay after a crown lengthening procedure. The disadvantage of this technique is also due to the dependence of the degree of fixation of the material to the dentin. A prudent approach to the choice of restorative material in the area of ​​the upper third of the canal will help prevent resorption of the tooth neck.

Vital teeth whitening

This category includes home whitening (day and night) and office whitening products. The decrease in interest in this technique lies in the fact that before the bleaching procedure, it is necessary to carry out clinical examination and prophylactic treatment of the patient. First, it is necessary to treat the soft tissues of the oral cavity, as well as replace low-quality restorations and fill teeth with carious lesions. Before the treatment, it is desirable to take a photograph of the patient's teeth with a sample of the color chart.

Patients with visible ceramic or composite restorations should be informed that these restorations cannot be bleached and may therefore become more visible. Patients should also be encouraged to continue treatment and need replacement. existing restorations only after bleaching. Patients who are planning to have veneers or full ceramic restorations, external bleaching should be recommended in order to reduce the layer of opaque that masks the underlying tooth tissue, allowing the dental technician to produce a more transparent and natural restoration. Tooth preparation should be delayed for 2-3 weeks after the whitening procedure, which will allow rehydration and full recovery of the teeth, and also allow the release of residual oxygen, which has a negative effect on the fixation of structures.

Whitening agents

Being represented in various options gels and pastes, hydrogen peroxide remains, as before, the most effective bleaching agent. The concentration of hydrogen peroxide is from 30% to 50%. Overnight whitening gels are available in 5% to 22% sodium perborate (sodium tetraborate peroxide), which is more effective than 2-5% hydrogen peroxide solution (but only for a short period of time). This shows that the oxidative efficiency of hydrogen peroxide in alkaline solution much higher than in acid.

Preliminary preparation of the patient:

The patient should be covered with a special protective cape to prevent contact of the bleaching agent on hands, skin or clothing.

The patient is wearing goggles.

If pain or any discomfort occurs, it is necessary to maintain feedback with the patient, so local anesthesia does not apply.

To protect the tissues from the side of the lip and tongue, before fixing the rubber dam, a light-curing material - Oraseal or Orabase paste should be freely applied.

Next clinical stage is the imposition of a rubber dam fixed to certain teeth with the help of dental floss. Oraseal can also be applied to existing amalgam restorations to reduce heat from the light source. The holes made by the perforator should be smaller than usual and placed more anteriorly in order to adequately cover the proximal gingiva.

Before applying the rubber dam frame, Vaseline is applied to the patient's lips. A wet wipe is placed over the patient's lips to prevent thermal injury from the heat lamp. During the procedure, it is very important to re-moisturize it.

Pre-treatment of teeth

Most authors agree that enamel etching before bleaching does not practically enhance its effect and leads to irregularities, tissue loss from the enamel surface (namely, 10 µm when treated with pumice and 20 µm after etching). In order to restore the lost gloss to the enamel, after bleaching it is polished with diamond paste. During this procedure, a 20 to 30 micron layer enriched with enamel fluorine is removed. In practice, there are unsuccessful cases of whitening without preliminary etching of the enamel. Before applying a whitening agent, the doctor must ensure that all foreign matter, such as Orabase, petroleum jelly, or varnish, is removed from the surface of the teeth. The next clinical step is cleaning the teeth with a pumice stone and thoroughly rinsing the mouth. Areas of cervical erosion, chipping or abrasion within the dentin can be protected with adhesive.

In most cases, practitioners need to follow the instructions for use, and freely apply the gel or paste to the surface of the teeth with a thickness of 3-4 mm without excessive pressure. In the case of hypoplasia or fluorosis, where spots or streaks occur, the doctor will modify the application method accordingly. Some teeth may be darker than others. As a rule, yellow-brown staining responds better to bleaching than blue-gray, the translucent incisal edge brightens faster than the cervical region of the tooth crown. This is due to the different thickness of the dentin.

Traditional vital whitening

The traditional whitening protocol requires the use of a special whitening lamp. After applying the hydrogen peroxide solution to the surface of the teeth, the lamp is set at a distance of 12-14 inches (corresponding to 30-35 cm) from the patient's face for 20-30 minutes. Most importantly, this does not require the doctor or assistant to move the light source from tooth to tooth.

Despite the fact that the heating source has a fixed temperature that does not cause thermal injury dental pulp, many patients complain of discomfort from radiant heat on the skin surface. After the teeth are isolated with a rubber dam, a single-layer disposable gauze pad is applied to the surface of the teeth, since Superoxol is a liquid and the gauze acts as a tampon and reservoir to keep this solution in close proximity to the teeth. A two-layer gauze pad, respectively, is placed over the rubber dam, covering lower lip and preventing the solution from entering the oral mucosa. Other devices that control the heating temperature are used with special metal tips. various forms and sizes for whitening in the area of ​​various grooves and recesses.

snow white beautiful smile is the best calling card. Wherein dark teeth won't be a decoration. True, after the treatment of caries, people often experience darkening of the enamel. Then the question of aesthetics comes to the fore. Previously, it was difficult to solve such a problem. However, nowadays medicine offers effective solution- intracanal teeth whitening.

Of course, you can also encounter darkened enamel when treating with leaky fillings, as well as colored pastes, or due to injuries. Various dyes also contribute. These include eating certain foods or drinks. Smoking negatively affects the color of teeth. In each case, intracanal bleaching will help.

Features of the procedure

Intracanal whitening(endobleaching) is a specific method of intracoronal correction of the color of molars. A special whitening gel is placed inside the tooth cavity. However, doctors prescribe x-ray examination to reveal discoloration of the enamel. Then a temporary filling is placed. An assessment of the condition of the teeth can be given after one to two weeks. Through the same period, the doctor conducts repeated procedure. As a rule, the result is achieved fairly quickly. According to statistics, for a full-fledged intracanal teeth whitening, about three to four procedures are enough.

The indisputable advantage of the endo whitening procedure is painlessness, high level efficiency and long-term results. Full restoration of the tooth is carried out only after obtaining the required shade. Similar procedure may be re-appointed a year later or later. It depends on how long the desired effect will be maintained in the individual case.

Before proceeding with endobleaching, it is necessary to take care of the sanitation of the oral cavity, eliminate any defects and carious lesions as well as tartar. To strengthen the enamel, a fluorine-containing composition is used. This results in dazzlingly white and strong teeth.

Possible side effects

In endo-bleaching are used chemical substances that destroy protein dyes. During this procedure, very active ingredients capable of providing effective impact. They allow to destroy the dyes accumulated in filling materials. However, the first procedure may not give a noticeable effect.

Another side effect such a technique is to weaken the strength of the tooth. This is due to the fact that in a tooth that is depulped, lesions are not restored after bleaching. Therefore, the probability of fracture of the dental crown is high. Consequently, maximum amount carrying out procedures for endobleaching - four. Greater number will not only have no effect. Additional endo-bleaching procedures can only weaken the dental crown.

Experienced professionals do not recommend the use of pastes, gels or formulations intended for self-whitening. After all, such means will not have an effect on internal cavity teeth. In addition, they contain abrasive substances. They destroy the enamel, increase its sensitivity.

Basic contraindications

Endo whitening like everyone else medical procedures, is not without certain contraindications. Among them:

A beautiful smile is the dream of almost everyone. modern man. "Living" teeth lend themselves well to whitening through the use of a number of methods, among which you can easily choose the right one for a particular patient. With depulped (without a nerve) and sealed dental units, the situation is more complicated. They darken or become mottled due to the influence of internal causes, so it is useless to act outside. In order to restore whiteness to a “dead” tooth, intracoronal bleaching will be required. What is this procedure, in what cases it can be carried out, who is recommended to refuse to use the technique - the answers to all questions can be found in this article.

Features of the endo whitening procedure

Intracanal bleaching is considered relatively new technology in the field aesthetic dentistry. Before deciding to do so, there are a few things to consider. characteristics. First of all, you should not hope that after in-channel clarification the element will remain white forever. The active chemical agent will remove the pigmentation, however, the tooth will still not receive nutrients and it will darken again over time. On average, the result “keeps” up to two years, but with proper care this period can be doubled.

In one visit to dental office reach tangible effect will not work. It is necessary to repeat endobleaching about three times with an interval of several days. Sometimes this is not enough, and the dentist after the examination prescribes the fourth procedure. It is not recommended to decide on the fifth, as this can lead to the development of complications.

Can a tooth with a dark filling be whitened?

When restoring with a filling, especially when it comes to the front teeth that are in the smile zone, the dentist tries to choose the most natural shade. However, sometimes after a while the patient is faced with the fact that the filling looks dark against the background of the rest of the teeth.

Often this is not due to the fact that the material installed during the restoration has darkened. This is the result of lightening natural teeth. For this reason, a natural question arises - is it possible to whiten a tooth if it has a dark filling? Modern technologies make it possible to carry out restoration and / or brighten filled teeth, but only if they are depulped. Then you can help in solving the problem with the help of intracanal tooth whitening.

Intracoronal whitening

Intracoronal bleaching is a procedure to lighten a tooth element that has been previously depulped. The result is achieved due to the introduction of a special clarifying composition not on the surface of the organ that needs clarification, but in its cavity.

The benefits of endo whitening include:

• affordable cost;
• high level of performance;
• it is possible to subject only one tooth to the procedure, without affecting the neighboring ones;
• intracanal whitening is absolutely painless;
• if all contraindications are taken into account, and whitening is carried out qualified specialist, the technique is safe;
• harmless to enamel;
• there is no need to grind the whitened tooth.

Stages of intracanal tooth whitening with photo

This article talks about typical ways to solve your questions, but each case is unique! If you want to know from me how to solve exactly your problem - ask your question. It's fast and free!

It is necessary to perform the procedure for bleaching a pulpless tooth or an element that has darkened under the influence of other internal causes in a dental office. In order for the session to be safe and effective, you should ask in advance about the qualifications and experience of the doctor. The photo for the article allows you to get an idea of ​​intracanal bleaching.

There are several main stages of endo whitening:

1. x-ray examination to establish the condition of the roots, determine the cause of the darkening of the teeth, select a treatment regimen;
2. rinsing the patient's mouth with an antibacterial solution;
3. removal of the old filling;
4. checking the condition of the roots, removing inflamed areas, if any;
5. filling a clean tooth cavity with a whitening composition;
6. laying a temporary filling (it can be installed for up to 4 weeks);
7. after the desired result is achieved, the temporary filling is removed and a permanent one is placed.

Indications and contraindications

Carrying out the procedure of intracoronal clarification will be ineffective if a dead tooth has darkened, which was sealed a long time ago (we recommend reading:). This is not a direct contraindication, but it will be simply useless to carry out the procedure.

Intracanal bleaching is indicated in the following cases:

• resorcinol-formalin type filling (tooth enamel acquires a pinkish color);
• silvering (the shade of the teeth can become black or pronounced gray);
• in the presence of cracks or microcracks in the enamel layer, through which substances that cause pigmentation penetrate;
• for whitening a pulpless tooth (that is, there should be no nerve in the element);
• if there is a dead nerve in the tooth;
• if the tooth has undergone significant damage with concomitant hemorrhage.

Not all categories of patients can carry out the procedure of intracoronal bleaching. Women during pregnancy and lactation, children and adolescents under the age of sixteen should not be exposed to internal tooth whitening. Patients suffering from dysfunction thyroid gland or diabetes of any type, endo-whitening of darkened teeth should also be abandoned. Also among the contraindications are:

Possible Complications

The difference between endo whitening and classical methods in terms of “external” teeth whitening is that internal procedure aimed at eliminating the pigmentation of dead tissues. Dyes that give an unattractive shade to the tooth in such cases penetrate deep into its tissues, so even a properly performed intracanal bleaching procedure does not always give the desired result. In this case, the doctor will recommend restoration with veneers.

Filling materials may contain persistent chemical dyes, as a result of which a composition with high concentration bleaching agents. Their use leads to a weakening of the dentin and an increase in the fragility of the tooth. As a result, fillings on such elements hold worse, and the risk of fracture of the crown part increases. To avoid such complications, endobleaching is recommended to be repeated no more than 4 times.

How to whiten a pulpless tooth at home?

Not everyone has the desire and opportunity to go to the dental office to whiten a darkened pulpless tooth. Can the procedure be done at home? There is a technology of night whitening using special caps. They are a kind of silicone or plastic covers for teeth. Kapu is filled with a special composition and put on at night. The method is safe, however, when whitening a long-standing pulpless tooth, it may be ineffective.

There is also a home whitening method, which is part of a complex of procedures and is carried out in parallel with the clinical one. The patient comes to the dentist, the doctor fills the tooth cavity with a mixture of sodium perborate and a 3% hydrogen peroxide solution (the substance looks like a paste). The composition remains in the hole until the next visit to the doctor - unnoticed by the patient, the tooth gradually brightens from the inside.
