Photobleaching of teeth, what is it? Which method to choose: an overview of the results and feedback. Detailed description of the procedure

Photobleaching is modern technique, which is carried out using special solutions and gels activated by a special ultraviolet, LED, halogen or laser lamp.

This technique provides for the possibility of brightening the enamel up to 12 tones in one visit. Depending on the characteristics of the structure of the teeth, patients can lighten the enamel in one visit, or undergo a more gentle course of three procedures. Lightening with ultraviolet light usually gives a highly visible result.

The principle of teeth whitening with the use of special lamps is simple - a special solution is used, the activity of which is increased by exposing it to ultraviolet or other type of radiation with a wavelength of about 450 nm.

The composition of the gel includes hydrogen peroxide, or its derivatives, active oxidizing agents. These substances penetrate into the surface layer of the enamel, and then disintegrate there under the influence of lamps on water (or other neutral substance) and atomic oxygen, which reacts with the pigment, oxidizing and brightening it.

Advantages and disadvantages of the technique

Photobleaching has a number of advantages relative to others:

But along with the benefits, this technique has some drawbacks:

1. Relative high cost. Photobleaching requires expensive equipment, which makes this method more expensive than other methods.
2. Development . In some patients, due to the weak mineralization of the enamel or its small thickness, whitening leads to the development of hyperesthesia. However, this can be avoided if the doctor preliminarily prescribes pastes containing strontium () for morning cleansing.
3. Violation of the rules of operation or The use of unsuitable lamps can lead to pulp burns and even. If the doctor uses a lamp that can strongly heat the tissues, this is fraught with the development of thermal pulpitis, since exposure to ultraviolet light for whitening is at least 15 minutes. Such a formidable complication can lead, first of all, to the use of lamps for curing fillings instead of special lamps for whitening teeth.

What lamps are used?

4 types of lamps are used:

• LED- safe for use, as they do not heat the tissue; you can lighten the enamel by 5-7 tones after 3 procedures for 8 minutes; an example of such a system is Luma Cool;
• laser use radiation in the range of 488-514 nm, they additionally increase the density of the enamel up to 40% and allow it to be lightened by 7-10 tones in one visit (laser beams are used by the Beyond whitening system);
• halogen lamps in combination with LEDs are used in the system;
• ultraviolet- the most effective, but unsafe systems in which tissue overheating is possible; in one session, it is possible to lighten up to 10 tones, in particular, ultraviolet rays are used in the whitening system.

How is everything going?

The bleaching technology depends on the peroxide gel used, as well as on the type of lamp used. However, preparation for teeth whitening always follows the same pattern:

1. The doctor tells the patient about the cost of a particular type of whitening, its effectiveness and possible consequences.
2. The doctor interviews the patient and conducts an examination, on the basis of which he determines the initial state of the enamel. At this stage, it is possible to conduct a TER-test showing the degree of mineralization.
3. Based on the data obtained, the doctor determines whether there are contraindications to teeth whitening, and which method will be the most effective and safe. After that, the doctor gives the patient recommendations regarding the procedure itself and preparation for it.
4. After desired method selected, the doctor talks about possible complications, dietary habits and other precautions after whitening.
5. Before the procedure begins, the doctor conducts a removal. This is an obligatory stage of preparation, after which some patients experience lightening of the enamel by 1-2 tones.

The whitening process itself depends on the light system used.

• glasses are put on the patient's eyes to protect the retina from UV rays;
• after that, the oral cavity is prepared - the lips are covered with a special balm, a buccal balm and napkins are installed that will protect the lips and cheeks.
• the doctor applies liquid to the gum, which, after light with a photopolymerizing lamp, will become a rubbery consistency;
• applied to teeth special composition— whitening gel Beyond ll, Beyond Max;
• after that, the Beyond lamp is directed to the oral cavity, the light exposure is carried out for 12 minutes, the whole procedure takes place in 3 stages.

For clarification using Zoom technology, the doctor:

• prepares the oral cavity and puts goggles on the patient's eyes, also uses a buccal retractor, wipes, liquid rubber dam;
• applies the gel to all surfaces of the teeth of the upper and mandible; in addition to peroxide compounds, the product contains amorphous phosphate calcium, which makes the effect on the enamel less aggressive;
• produces light activation of the gel, the duration of illumination is 15 minutes, after which the gel is applied and activated with light 2 more times; thus, total duration procedures - 45 minutes.

When using the Luma Cool system, the doctor:

• puts on goggles for the patient, and also carefully isolates the oral mucosa with the help of a retractor, napkins and liquid rubber dam;
• applies a whitening gel;
• the lamp of the device is set so that the teeth of the upper and lower jaws are illuminated;
• exposure under the lamp lasts 8 minutes, after which the cycle is repeated 2 more times; the total duration of the whitening procedure is 24 minutes.

Which method to choose: review of results and feedback

When choosing a bleaching method important role plays the degree of darkening of the enamel and its thickness, as well as the degree of mineralization.

For a slight lightening of the enamel or with its weak mineralization, LED or halogen bleaching is suitable. LED and laser exposure are considered the most gentle.

For teeth with strong pigmentation and a large thickness of enamel, enamel whitening with ultraviolet light is suitable, which allows you to get the most pronounced and quick effect.

Our photo gallery of patients before and after the procedure, as well as their reviews, will help you evaluate the effectiveness, as well as compare the results after applying all the methods that are used for photowhitening of teeth.

About 3 months ago I decided it was time to say goodbye to my yellow teeth - ugly, especially for a girl. After reading about different ways bleaching, determined on the light.

After I arrived at the clinic, the doctor told me clearly about how the procedure would go, what dietary restrictions should be, what consequences might arise. But I was determined.

After the procedure, I compared the color of the enamel with the “before” photo, and was pleasantly surprised - my teeth became much whiter! A few days after bleaching, it was a little painful from the cold, but I followed the recommendations - I used the paste for sensitive teeth, avoided coloring products. And thanks to this, I am still happy with the effect of this procedure. I am very satisfied, because now I am 100% confident in myself.

Nina, 29

Agreed to teeth whitening with ultraviolet light. The teeth became, of course, not porcelain-white, but light, as I wanted. The first days the pain from the cold was severe, I had to go to the doctor so that she covered her teeth with fluorine varnish.

After that, there are almost no problems. It's been 4 months now. Teeth darkened a little, but this is from the fact that I do not adhere to a strict diet. And so - super, for important event, and to please yourself - that's it!

Lena, 31

I whitened my teeth two days ago. My enamel is thick, but yellow. Immediately asked the doctor to varnish the enamel after the procedure. I can say that although my teeth sometimes hurt, I don’t have anything as terrible as some write. The enamel became whiter, although not quite white.

I am now on a diet, do not eat or drink coloring foods, brush my teeth with fluoride toothpaste. Sometimes a little if you eat ice cream, but you can put up with it. Or not to eat ice cream ... But positive - the sea! I don't understand why I didn't do this before?); after the procedure, as well as the use of .

Price

Depending on the equipment used, the price of photobleaching ranges from 6-8 to 25 thousand rubles.

Teeth whitening involves two processes:

1. The whitening gel applied to the enamel, containing 30-40% hydrogen peroxide, penetrates into the surface layers of the dentin
2. Photocatalysis, accelerating and activating the rate of penetration of the gel into the dentin of the tooth.

The light source is halogen, LED or ultraviolet lamps. Thanks to light pumping, the process of gel penetration through the enamel is accelerated, and the whitening time is reduced. Today, the most famous professional photo-whitening system in Russia is (zoom) zoom 3 teeth whitening, patient reviews confirm this.

How is teeth whitening performed?

The clinical protocol for photobleaching of teeth is carried out in the following way:

1. Determination and fixation of the initial color of the teeth.
2. Installation of the cheek retractor.
3. Application of gingival protective gel on the gum.
4. Applying whitening gel to teeth.
5. The direction of the light flux on the whitening gel.
6. Removal of the remnants of the whitening gel from the enamel.
7. Removal of protective gel from gums.
8. Coating of tooth enamel with protective fluorine varnish and remotherapy.

This is how zoom 3 teeth whitening works. On average, the entire whitening session takes about one to one and a half hours. To maintain whitened teeth for as long as possible, in some cases, zoom home whitening is prescribed.

Photobleaching results

The results and durability of photobleaching of teeth depend on several parameters:

1. from initial situation and color of teeth
2. from the implementation of the recommendations of the dentist after tooth whitening.

As a rule, it is possible to whiten teeth by 3-5 tones compared to the original version. But it is necessary to take into account all factors, for example, with fluorosis or tetracycline teeth, a satisfactory result may not be achieved, so it makes sense to immediately think about installing veneers or lumineers. It is also very difficult to bleach live grey-white teeth (according to the "Vita" scale, sector C), here we are not talking about 3-5 tones, as they say, you would change the color of your teeth by at least 1-2 tones.

In addition, it must be understood that even if all the recommendations are followed, the period of preservation of the new color of the teeth will not exceed 2-3 years.

Tooth sensitivity during photobleaching

To prevent tooth sensitivity after photobleaching, it is necessary to prepare for the procedure. The dentist recommends curing all caries, as well as removing dental plaque and tartar. It is necessary to carry out remotherapy, which consists in saturation of dentin and tooth enamel with calcium and phosphorus. After the zoom whitening procedure, without fail tooth enamel is covered with fluoride varnish in three four days in a row and remotherapy is also carried out. The first three days limit the intake of hot and very cold food. And home hygiene and brushing of teeth is carried out with the help of toothpastes that reduce tooth sensitivity.

Harm to teeth during photobleaching

The main and most serious harm for teeth during a photo-whitening session, it can be applied due to overheating of the dental pulp, as a result of thermal radiation from a halogen lamp. As a complication, the development of thermal pulpitis is possible. This mainly happens when the clinical protocol dental photobleaching.

Therefore, it is very important to whiten the dentition by qualified doctors, with experience in aesthetic dentistry. Problems are also possible with too frequent whitening procedures, the required rest period between sessions is at least 9 months.

There are many ways to make teeth whiter. But what is the best teeth whitening? This article is the answer to this question.

At first glance, it is enough to analyze the advantages and disadvantages of one or another type of whitening in order to understand which technology is better. In reality, things are a little more complicated. The fact is that each person has individual teeth. Therefore, the final conclusion about the effectiveness of enamel lightening technology can only be taken into account the feedback from patients of dental clinics.

Professional whitening

What we see in the search results in the browser in response to a request: best whitening teeth? Hundreds, and maybe thousands of thematic pages with advice from incomprehensible "specialists", and sometimes outright charlatans, recommending the best teeth whitening. At the same time, the advertised systems must certainly be used at home. Naturally, you should not trust such advisers, because home whitening teeth for safety and efficacy can't compete with a professional.

My teeth are naturally yellow. For a long time I did not dare to make them lighter, but then whitening strips caught my eye. Advertising on the package promised excellent results, and I was led. I did everything according to the instructions. My teeth really became a little lighter, but along the way, I burned my gums with strips. They were sick for a long time. A few months later I went to the dentist. Only in the clinic they did a good whitening for me.

What is the best whitening?

Dentistry offers several systems professional whitening teeth. All of them are good. All have advantages and disadvantages. So which system should you choose? The one with the most pros and the fewest cons. Therefore, each system should be evaluated according to the following parameters:

• Safety.
• Efficiency.
• Speed.

Photobleaching

It's relative new method enamel lightening, which allows you to work safely even with sensitive teeth. Bare roots, cracked enamel and even chips are not a hindrance to photobleaching, since this technology has healing effect and helps repair damaged enamel. Reviews of this technology are overwhelmingly positive.

During dental treatment in the clinic, the dentist suggested that after the completion of the procedures, I should lighten my teeth with photobleaching. I agreed. The whole procedure took 30 minutes and gave an excellent result. The only drawback is that the sensitivity of the teeth has increased. The doctor said it would go away with time.

Marina, Moscow

Photobleaching is carried out using a gel applied to the teeth. His dentist irradiates special lamp. Ultraviolet activates active substances in the gel, due to which the enamel is lightened.

Photobleaching has the following advantages:

When photobleaching, you should not be afraid for ceramic, metal and plastic prostheses. They will not change their color.

The advantages of photobleaching also include the low cost of the procedure.

Chemical bleaching

Frankly, the chemical method little different from photobleaching. In both cases, a special whitening gel is used. But with the chemical method, no catalyst is required to activate the gel.

Chemical bleaching gives positive effect only if there are no composite, ceramic or polymer inserts on the teeth. The fact is that the gel can only work with natural dentin. You should also consider the natural color of the tooth enamel. When whitening yellowish teeth, this method gives good result, but Brown color does not lend itself well chemical attack. grayish enamel chemical method does not bleach at all.

The main advantage of chemical bleaching is no heating of the teeth.

Every year I do chemical teeth whitening in the clinic. I like coffee very much, so the procedure has to be repeated often. I am quite satisfied with the result, but after the fifth procedure, the teeth became too sensitive.

Michael, Eagle

Mechanical and ultrasonic whitening

Such clarification gives a good result, but it cannot be called a full-fledged whitening. The fact is that mechanically you can only remove deposits from the surface of the teeth. In fact, this is a professional teeth cleaning.

The most famous mechanical whitening technology is AirFlow. It looks like this: to the patient's teeth the nozzle is supplied, from which a mixture of water, air and a very fine abrasive is supplied under pressure. This jet quickly removes all excess from the enamel and returns it to its original color.

Ultrasonic whitening is a more expensive option for mechanical whitening. With this method of cleaning, the risk of damage to the enamel is minimal.

Mechanical and ultrasonic clarification does not make the enamel lighter than it was by nature.

Whitened teeth with ultrasound. The result is good. Along the way, the doctor cleaned gum pockets. This is important to me because sore gums- my problem.

Angelina, Saransk

At its core, laser lightening is a kind of photobleaching. However, due to the fact that the active gel is catalyzed by a laser, dentists separately highlight this whitening system. The laser allows doctors to more precisely act on each tooth individually. That is, the entire bleaching process becomes completely controlled, which cannot be said about chemical and photobleaching.

Using laser beam damage to the enamel or soft tissues of the oral cavity is excluded. The procedure is completely painless and allows for short term get a very good result.

Advantages of the laser method:

• This procedure strengthens the enamel.
• The laser is safe.
• Doesn't take long.
• Gives good results.
• It has a bactericidal effect and serves as an excellent prevention of caries.
• Long shelf life results achieved- up to 10 years.

There is only one disadvantage of laser whitening - high price procedures.

Decided to leave a review. I went through five laser whitening procedures: I wanted to get maximum lightening and got it. Friends frightened that the procedure is quite unpleasant. Everything went great for me. If a laser whitening causes discomfort I advise you to change doctors. Good luck to all.

Conclusion

It's time to sum up. This article has reviewed the most common whitening systems. Exotic and homemade enamel lightening options were not considered. What conclusion can be drawn after analyzing the advantages and disadvantages of all the considered methods? He is obvious. A combination of pros and cons the best way whitening dentists themselves consider laser whitening. It allows cope with any variant of darkened enamel, has no restrictions, completely safe. Of course, this type of whitening is the most expensive, but the result is worth the money spent.

Millions of people suffer from tooth discoloration. This is one of the most common cosmetic problems that are now being addressed to doctors in the beauty industry. Even those who regularly brush their teeth, floss, and visit the dentist regularly may find that food, drink, exposure environment and even just age takes away the whiteness and attractiveness of their smile. Luckily, modern science is able to offer a wide range of teeth whitening products that are becoming more effective and safe every year.

Today, the choice of tools that brighten enamel is greater than ever. And their range ranges from whitening toothpastes and kits to home use available for free sale, up to professional systems office whitening when the whole process takes place in the doctor's office under his control. And it is not for nothing that the method of professional whitening has now gained the greatest popularity.

What is phototeeth whitening

Among all the methods of in-office use, bleaching with light or photobleaching has gained particular popularity. In fact, this way is not a separate, fundamentally different option for obtaining snow-white teeth. By itself, the light does not affect the enamel of the tooth and does not cause any direct changes in its structure. Photobleaching is one of the options for chemical bleaching. For more light shade a special gel is used, which is based on hydrogen peroxide or carbamide peroxide. A light source is needed to initiate a chemical reaction.

Thus, the main component of photobleaching is gel. Since the procedure is performed under the supervision of an experienced doctor, the concentration active substance- peroxides - can be very high and reach up to 40%. Under the influence of a radiation source, chemical reaction destruction of the agent with the release of active oxygen. Oxygen is a strong oxidizing agent and easily penetrates tooth enamel, destroying and removing impurities that give teeth dark color. The longer the exposure of the components to the surface and the higher the concentration, the more coloring pigments will be eliminated and the lighter the final shade will be.

According to the light source for the reaction, photobleaching can be divided into:

• Light-emitting diode (LED). It is characterized by minimal heat generation during operation, therefore it is considered the safest, since there is no destructive thermal effect on internal structure tooth. Diodes emit cold blue light.
• Plasma. Today it is considered the best option in terms of efficacy and safety for the patient. It is characterized by high power and minimal heating during operation, but the equipment is very expensive.
• Halogen. One of the most common light source options in modern office whitening. Efficiency and power allow you to achieve the desired results, however increased excretion heat during operation forces the use of special technical solutions to reduce it harmful influence, such as infrared filters in
• Ultraviolet (UV). Ultraviolet light is the best catalyst for the chemical reaction to release oxygen from the gel, so until recently this type of lamp played a leading role in office whitening systems. Unfortunately, high-power ultraviolet radiation has a very destructive effect on human tissues, including the teeth themselves. If the dentist can isolate outer area, then nothing can be done about the oral cavity, so it is exposed to a detrimental effect. That is why, after the discovery of the properties of cold blue LEDs, UV lamps began to be actively forced out of the market.

Who will suit?

Photobleaching, like other methods of enamel lightening, has its own areas of application. Whitening procedures today are safe and affordable for a wide range of consumers. Best Results can be achieved in patients with moderate or closer to severe tooth discoloration. Particularly well treated yellow teeth. But if your color has a gray or reddish tint, the effect may be much lower than expected.

In addition to the original color itself, before deciding on a whitening procedure, it must be taken into account that there are cases when such manipulations are contraindicated.

• The presence of visible artificial structures. If the patient has such structures as veneers, crowns or, then it must be remembered that they do not change the light when exposed to the agent. Then, after the end of whitening, they may need to be replaced due to a strong difference from the new color of the teeth.
• Internal lesions of the tooth. If the tooth has darkened due to pulp necrosis or nerve death, as well as the presence of white spots, this indicates a discoloration deep inside, in the dentin and pulp. Whitening will not help restore whiteness in such cases, as it acts more with enamel. With such lesions, other methods of dealing with discoloration may be needed, such as intracanal bleaching or veneers.
• Weakened enamel. If, as a result of some reason, the enamel has been eroded or there are visible signs of surface damage, exposure to aggressive chemical agents can only worsen the situation and lead to serious complications.
• Increased tooth sensitivity. When a patient suffers from this feature, whitening may simply become impossible, as active oxygen enters the dentinal tubules and exacerbates sensitivity.
• The presence of caries and leaky fillings. It is important to ensure that the whitening gel is exposed to the surface and not allowed to enter the tooth. Otherwise, this may lead to serious consequences until the death of the pulp and nerves.

How whitening works

In order to get the desired result, the patient needs to take a number of preliminary steps to prepare for the procedure. Since the radical change in the color of the teeth, which photobleaching offers, implies a serious burden on the patient's body, especially his oral cavity, it is necessary to carry out careful preparation. Allotment heightened attention preparatory stage will allow not only to get the desired result, but also reduce the number and severity.

First of all, you need to get a consultation with a dentist and conduct a thorough analysis of the condition of the teeth. Experienced doctor will help not only to determine the causes of discoloration of the teeth, but also help to make right choice way to lighten them. In addition, if necessary, a therapeutic treatment. Same way important step is holding professional cleaning teeth to eliminate all surface contaminants and ensure an even discoloration of the teeth.

If approval is received from the doctor for the whitening procedure, then the process itself will take one session and about 1 hour of pure time.

1. Teeth are cleaned from dirt, plaque and hard deposits are removed, followed by polishing. After this procedure, using the standard Vita shade scale, the initial color of the enamel is determined. The data is entered into the map.
2. The treatment area is released with a retractor, and the oral cavity is isolated with a rubber dam or cotton rolls for free access and tissue protection.
3. A protective gel strip is applied to the gingival margin. It insulates the gums from harsh chemicals and radiation exposure.
4. Apply to the dried surface. Its concentration is determined by the doctor depending on the specific clinical picture.
5. The surface is irradiated with a lamp. Under the influence of light, the reaction proceeds and the coloring pigments are destroyed.
6. The spent gel is removed and a preliminary evaluation of the results is made. If the goal is not achieved, a new portion of the gel is applied and activated. The process is repeated until the result is obtained, but no more than 3-4 times per visit.
7. The final removal of the remaining gel is carried out. The protective layer is removed from the gums. The oral cavity is washed. A drug is applied to the enamel to remineralize and reduce sensitivity.

The effect of the procedure

No wonder photobleaching is considered one of the most effective methods. At controlled level side effects and high speed, this method offers a serious brightening of the color of the patient's teeth. And although the specific result is very individual and will depend on the condition of the enamel, heredity, the causes that caused the discoloration and the initial shade of the teeth, today this is the best that dentistry has to offer in this area.

A good result is teeth whitening 3-8 shades according to the Vita scale. And all this can be done in one visit! It is not uncommon when whitening reaches 10 tones, despite the fact that the standard shade scale has 16 gradations. So photobleaching may well offer getting the most bright color- B1 - a wide range of patients.

Side effects

Like almost any medical procedure, teeth whitening, in addition to the benefits, entails the appearance of certain side effects. The reactions of the organism are difficult to predict with accuracy and there are many reasons on which the development of events in each case will depend. Nevertheless, the accumulated experience allows us to say that there are a number of side effects that most patients experience both during and after the whitening procedure.

• Increased sensitivity. It can manifest itself both with physical contact and with contact with cold or hot.
• Irritated gums. Whitening gel is very aggressive. If during the procedure there was a leak outside the working area, a chemical reaction can damage the gum, up to discoloration of some area.
• Pain and discomfort in the teeth. This sign can serve as an indicator that penetration has occurred active components inside the structure of the tooth and its nerve is affected. Or, as a result of excessive heating, damage to the pulp has occurred. Same way common cause is the dehydration of the enamel during the procedure.

Photobleaching systems

There is a wide range of solutions on the market today from different manufacturers. All of them are based on the principle of activating the whitening gel with a light source. However, the implementation of this idea can vary widely, which distinguishes products from competitors.

Zoom

This whitening system from DISCUS DENTAL, which is currently owned by the well-known manufacturer PHILIPS, is one of the most famous and popular on the market today. It is based on the use of LED lamps with a special infrared filter. This solution allows not only to effectively control the process of gel operation, but also to avoid thermal effects on the structure of the patient's teeth. The process itself takes about 45 minutes and allows you to achieve clarification in 6-8 tones. Office Whitening Kit Zoom! includes components for all three stages of treatment: preparation, whitening and post-treatment care.

Beyond Polus

One of the new products on the market that offers innovative LightBridge technology. This method allows you to completely exclude UV radiation from the range of the light source, while maintaining the radiation power, which is important for the effectiveness of the whitening gel. A special lamp that emits light of two wavelengths at once, in which both halogen and LED radiation are used. Also, the BEYOND POLUS system has the function of precise positioning, which allows you to narrow the range of irradiation to a narrow area, up to a single tooth. In 30 minutes you can get a smile up to 8 tones lighter.

Elena Kudryashova

Photobleaching of teeth - simple and effective procedure through which you can become the owner snow-white smile in just one session.

Why is photobleaching necessary?

As a rule, in many people, over time, the teeth begin to darken. This may happen as a result frequent use coffee, tea, red wine, as well as other drinks and products that contain dyes.

In addition, the enamel is negatively affected by the tar formed when smoking cigarettes, and medications especially antibiotics. Thanks to innovative technologies was developed modern method, which allows you to effectively and efficiently get rid of plaque and give the enamel a snow-white color.

Popular methods of photobleaching

The name of this method comes from the word "photos", which in Greek means "light". The procedure itself is performed using gels containing hydrogen peroxide, however, activated chemical substances only under the influence of special photolamps.

To date, there are several ways to whiten:

1. Halogen. This method involves the use of light sources with a halogen emitter, due to which the dental tissues practically do not heat up.
2. LED. This method is the safest, since the LEDs do not have a thermal effect on the enamel.
3. ultraviolet. Such lamps are considered the most powerful. They highlight a large number of heat, resulting in a sufficiently strong heating of the teeth.

Most modern systems photobleaching using cold light:

• Beyond Polus.
• Luma Cool.
• zoom.

Process details

First, the patient comes for a consultation with the dentist to examine the oral cavity. The specialist determines the condition of the gums and teeth and, if necessary, removes plaque and tartar. In the presence of caries, appropriate treatment is prescribed, and only after filling, the client undergoes photobleaching of teeth.

The procedure itself usually takes no more than an hour. It is carried out only in the dental office, in comfortable and safe conditions for patients. The doctor determines the color of the enamel using a special scale, asks the client what result he wants to get, and then installs a mouth expander (retractor) in order to provide access to the teeth. soft tissues isolated with cotton swabs or napkins. After that, the gums are covered with a protective agent, and a whitening composition is very carefully applied to the enamel so that it does not get into the tissues of the oral cavity.

To date, dentists use several types of gels:

• Preparations, which include a light-active catalyst that speeds up the process, as well as various emollients, for example natural oils and glycerin.
• Products containing amorphous calcium phosphate.

Under the influence of a halogen photo lamp, the components contained in the mixture begin to release substances that break down dark patina present on enamel. As a rule, radiation is carried out for 30 minutes, and then the chemical is washed off the teeth and applied to them. new layer. This procedure carried out until the desired effect is achieved. Whitening is usually carried out in two or three stages, each of which lasts about 20 minutes. However, keep in mind that in one session it is not recommended to repeat the procedure more than six times.

Photobleaching results

According to experts, using this method, you can whiten your teeth by 8-12 tones. Many people want to use this service after reading positive reviews about it on the Internet. However, before taking such a step, it should be borne in mind that the effect obtained largely depends on your individual features, for example from the natural color of the enamel. It is also important to remember that in about 7% of the population, enamel cannot be processed at all.

Teeth with gray tint are usually less subject to lightening than yellows, so it will be difficult for them to give a dazzling white color. Unfortunately, patients with fluorosis or tetracycline teeth also have little chance of becoming owners of a snow-white smile. During the procedure, the doctor acts only on dental tissues, so it should be borne in mind that teeth made of plastic and ceramics also do not change their color.

But if the enamel darkened as a result frequent smoking or drinking coffee, after the session, patients can expect a positive result.

Despite the fact that the effect of the procedure is noticeable immediately, final result can be seen in about 10 days.

Treatment of sensitive teeth

Despite all the advantages of this method, it can have backfire for people with sensitive teeth. Enamel can be adversely affected heat and gels, which include chemicals.

In order to avoid this problem, you should first make an appointment with a dentist who will identify factors that serve as contraindications and prescribe suitable treatment. Decreasing the sensitivity will also help. professional hygiene and remineralizing paste, which is applied to the enamel after the procedure.

Side effects

Unfortunately, this service has not only advantages, but also certain disadvantages. How harmful can phototeeth whitening be? Complications can arise if you turn to unqualified specialists.

For example, if the condition of the patient's oral cavity is incorrectly assessed or if the exposure to a photolamp is too powerful, there is a danger of pulp overheating, which, in turn, can lead to necrosis.
