Intra-canal teeth whitening is a modern technique for restoring the aesthetics of darkened teeth. Endobleaching is carried out using a special gel. The technique restores the color of the tooth from the inside, and does not lighten the enamel, as with traditional way bleaching.
The procedure has already received the approval of specialists. The technique pleased patients with pulpless teeth. Endobleaching is cheaper than installing crowns. There are other advantages of the original method, which returns a pleasant color to a filled tooth. For you - information about modern technology.
What is intracanal whitening:
Intracoronal loss of whiteness occurs under the influence of various factors:
Please note the restrictions:
The procedure has several positive aspects:
Pay attention! An innovative in-canal whitening technique replaces the installation of crowns. The darkened, pulpless unit is visible through the all-ceramic plate; the aesthetics cannot be completely restored.

The innovative technique has several stages. No special preparation is needed for the procedures. Required condition– taking an x-ray of the problem unit to control the quality of canal filling.
Stages of intracanal teeth whitening:
The technique is complex, Proper intracoronal bleaching requires high professionalism. Unnecessary procedures can destroy the restored unit; it is dangerous to lighten the internal tissues more than three or four times during one course.
The rules and methods for treating gum inflammation in children are described on the page.
The cost of modern technology depends on several factors:
The price includes:
The average price of intra-canal whitening for one unit is 500–600 rubles. The total cost of the course is in the range of 8,000–10,000 rubles, taking into account all procedures and visits to the dentist.
Each tooth reacts differently to the action of dental gel with a whitening effect. To lighten the tissues of one tooth, two visits are required; with another unit, the dentist has to work for three visits.
Patients appreciated the effectiveness of the original technique, restoring the aesthetics of the problem unit. Reviews of intra-canal teeth whitening are often positive. The only caveat is that not all clinics offer patients modern methodology to restore a pleasant color pulpless tooth.
Sometimes the dentist recommends installing thin onlays on the teeth to improve the aesthetics of the dentition. Porcelain or ceramic plates are much more expensive; they only mask, but do not eliminate the yellowness or grayness of the problematic unit of the dentition.
If a pulpless tooth darkens, do not rush to collect a fabulous sum for the installation of veneers or lumineers. Look for a dental clinic that performs in-canal whitening. Just 2-3 weeks, and you will return a pleasant appearance to the problem unit, lighten the tissue from the inside. Safe, effective technique recommended for restoring the aesthetics of pulpless/injured units.

Frequently asked questions
First of all, one that does not injure the gums during use. At the same time, the quality of hygiene oral cavity depends more on whether your teeth are brushed correctly than on the shape or type of toothbrush. Regarding electric brushes, then for uninformed people they are a more preferable option; although you can clean your teeth efficiently with a simple (manual) brush. In addition, a toothbrush alone is often not enough - floss (special dental floss) must be used to clean between the teeth.
Rinse aid is optional hygiene products, which effectively cleanse the entire oral cavity from harmful bacteria. All these products can be divided into two large groups - therapeutic and preventive and hygienic.
The latter include rinses that eliminate bad smell and promote fresh breath.
As for therapeutic and prophylactic ones, 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 in the composition of various types of biologically active ingredients. Therefore, the rinse aid must be selected for each specific person individually, as well as toothpaste. And since the product is not washed off with water, it only consolidates the effect of the active ingredients of the paste.
This type of cleaning is completely safe for dental tissues and causes less trauma. soft fabrics oral cavity. The point 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 area and cool the tip of the instrument). The cell membranes of pathogenic microorganisms are ruptured by these molecules, causing the microbes to die.
It turns out that ultrasonic cleaning has a comprehensive effect (provided that really high-quality equipment is used) both on the stone and on the microflora as a whole, cleansing it. Oh mechanical cleaning you can't say that. Moreover, ultrasonic cleaning more pleasant for the patient and takes less time.
According to dentists, dental treatment should be carried out regardless of your situation. Moreover, a pregnant woman is recommended to visit the dentist every one to two months, because, as you know, when carrying a baby, the teeth are significantly weakened, suffer from a deficiency of phosphorus and calcium, and therefore the risk of developing caries or even tooth loss increases significantly. To treat pregnant women, it is necessary to use harmless anesthetics. The most appropriate course of treatment should be selected exclusively by a qualified dentist, who will also prescribe the required medications that strengthen tooth enamel.
It is quite difficult to treat wisdom teeth due to their anatomical structure. However, qualified specialists successfully treat them. Wisdom teeth prosthetics are recommended when one (or several) adjacent teeth are missing or need to be removed (if you also remove a wisdom tooth, there will simply be nothing to chew). In addition, removal of a wisdom tooth is undesirable if it is located in the correct place in the jaw, has its own antagonist tooth and takes part in the chewing process. You should also take into account the fact that poor quality treatment can lead to the most serious complications.
Here, of course, a lot depends on a person’s taste. So, there are absolutely invisible systems attached to inside teeth (known as lingual), and there are also transparent ones. But the most popular are still metal bracket systems with colored metal/elastic ligatures. It's really fashionable!
To begin with, it is simply unattractive. If this is not enough for you, we present the following argument - tartar and plaque on the teeth often provoke bad breath. Is this not enough for you? In this case, we move on: if 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 form, pus constantly flows out of them, and the teeth themselves become mobile ). And this is a direct path to loss healthy teeth. Moreover, the number of harmful bacteria increases, which causes increased dental caries.
The service life of a well-established 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. Typically, this period will depend both on the design of the product and on how carefully the patient cares for it. That is why during cleaning mandatory 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 dental cyst can be done therapeutically or 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 which allow you to save the tooth. This is, first of all, cystectomy - a rather complex operation that involves 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 (the part) is restored with a crown.
As for therapeutic treatment, then it consists of cleaning out the cyst through a root canal. This is also a difficult option, especially not always effective. Which method should you choose? This will be decided by the doctor together with the patient.
In the first case, professional systems based on carbamide peroxide or hydrogen peroxide are used to change the color of teeth. Obviously, it is better to give preference to professional whitening.
A beautiful smile is the dream of almost everyone modern man. “Living” teeth lend themselves well to whitening using a number of techniques, among which you can easily choose the one that suits a particular patient. With depulped (without a nerve) and sealed dental units, the situation is more complicated. They darken or become stained due to the influence internal reasons, so it is useless to influence from the outside. To restore the whiteness of a “dead” tooth, intracoronal bleaching will be required. What this procedure is, in what cases it can be performed, who is recommended to refuse to use the technique - answers to all questions will be found in this article.
In-canal bleaching is considered relatively new technology in the field aesthetic dentistry. Before you decide to carry it out, you should consider some characteristic features. First of all, you should not hope that after in-channel clarification the element will remain white forever. The active chemical agent will eliminate pigmentation, but will still not penetrate the tooth. nutrients, and it will darken again over time. On average, the result “lasts” up to two years, but when proper care this period may double.
It is not possible to achieve a noticeable effect in one visit to the dental office. Endobleaching has to be repeated about three times with an interval of several days. Sometimes this is not enough, and after an examination the dentist prescribes a fourth procedure. It is not recommended to decide on the fifth, as this can lead to the development of complications.
When restoring with a filling, especially when it comes to the front teeth located in the smile zone, the dentist tries to choose the most natural shade possible. 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 restoration has darkened. This results from the lightening of natural teeth. For this reason, a logical question arises: is it possible to whiten a tooth if it has a dark filling? Modern technologies make it possible to restore and/or lighten filled teeth, but only if they are pulpless. Then you can help solve the problem with intra-canal tooth whitening.
Intracoronal bleaching is a procedure for lightening a tooth element that has previously been depulped. The result is achieved by introducing a special lightening composition not onto the surface of the organ that needs lightening, but into its cavity.
The benefits of endobleaching include:
This article talks about typical ways to solve your issues, but each case is unique! If you want to find out from me how to solve your particular problem, ask your question. It's fast and free!
The procedure for whitening a pulpless tooth or an element that has darkened under the influence of other internal reasons must be performed in a dental office. In order for the session to be safe and effective, you should inquire in advance about the qualifications and experience of the doctor. The photo accompanying the article allows you to get an idea of in-canal whitening.
There are several main stages of endobleaching:
The intracoronal lightening procedure will be ineffective if a dead tooth that was filled a long time ago has darkened (we recommend reading:). This is not a direct contraindication, but it will simply be useless to carry out the procedure.
In-canal bleaching is indicated in the following cases:
Not all categories of patients can undergo intracoronal bleaching. Internal tooth whitening should not be performed on women during pregnancy and lactation, children and adolescents under the age of sixteen. For patients suffering from dysfunction thyroid gland or diabetes mellitus of any type, you should also avoid endobleaching of darkened teeth. Contraindications also include:
The difference between endo-whitening and classical methods of “external” teeth lightening is that internal procedure aimed at eliminating pigmentation of dead tissue. Dyes that give an unattractive tint to a tooth in such cases penetrate deep into its tissue, so even a properly performed intra-canal whitening 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 a high concentration of bleaching substances will be required to eliminate pigmentation. Their use leads to weakening of dentin and increased tooth fragility. As a result, fillings on such elements do not hold up as well, and the risk of fracture of the coronal part increases. To avoid such complications, endobleaching is recommended to be repeated no more than 4 times.
Not everyone has the desire or opportunity to go to a dental office to whiten a darkened, pulpless tooth. Is it possible to carry out the procedure at home? There is a technology for night whitening using special trays. They are a kind of silicone or plastic covers for teeth. The mouthguard is filled with a special composition and worn at night. The method is safe, however, when whitening a long-depulped tooth, it may be ineffective.
There is also a method home whitening, which is part of a set 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 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.
Darkening of teeth can occur not only from the outside, but also from the inside. And in such cases, the most advanced external whitening techniques, such as laser or Zoom 3, are absolutely ineffective. Why does internal staining occur, and how to deal with it?
The main reason for discoloration of molars is medical intervention. After caries treatment and filling, internal tissues may become stained. So, for example, when using filling material with an admixture of silver, fabrics are dyed gray, formaldehyde-based compounds give teeth a pink tint. The unnatural tone is also visible after the crown is applied, since in the gum area the lower part of the molar remains uncovered, and the gum itself acquires a bluish tint.
Other reasons for discoloration of teeth from the inside:
Indications for endobleaching of teeth include darkening of teeth due to the above reasons.
Contraindications are:
Intra-canal teeth whitening is performed after X-ray examination, allowing us to clarify the features of the preliminary treatment method. After this, the doctor opens the tooth cavity, cleans out dark tissues, and introduces a special whitening gel based on sodium perbonate. The patient is given a temporary filling.
By acting directly on the affected area, the whitening composition allows you to achieve excellent results. But obvious lightening is achieved after the second or third procedure, after which you can put permanent filling. In this case, the doctor installs special gaskets between the filling and the walls of the tooth to prevent darkening in the future. The total treatment period is 2 weeks.
Using a bleaching solution more than 4 times is dangerous, as it can lead to tissue destruction from the inside.
An important advantage of teeth whitening is the absolute painlessness of the method. Its effectiveness allows it to be used for patients with filled “living” teeth, as well as for people with “dead” molars and when wearing modern ceramic crowns, through which the darkening of the covered tissues comes out.
Possibility of periodic access as needed - Another advantage of intra-canal teeth whitening. Reviews demonstrate that the effect persists for up to several years, but if the molar darkens again, the doctor can open it again and carry out sanitation from the inside.
It is important to remember that endobleaching is the same medical intervention in the tooth cavity as its treatment, and therefore requires high professionalism of the doctor. With a qualified approach, it is possible to completely get rid of the unpleasant shade of enamel without consequences.
The main disadvantage of treating caries or pulpitis is the discoloration of the treated units. First, their crown part darkens, and then the root structure changes color.
Previously, this problem was solved in only one way - covering with veneers or crowns. Nowadays, a new technique has been developed and successfully used in dentistry - endo-bleaching (otherwise intra-canal bleaching).
This is a method in which teeth are lightened by introducing root canals bleaching agents. This technology has revolutionized aesthetic dentistry and added to the list of services that satisfy patients’ aesthetic requirements.
Previously existing bleaching methods showed good results, but only on vital (living) units. The same cannot be said about the change in color of non-vital elements when the result of the procedure did not coincide with the expected result.
Now it is possible to return the original color to those teeth whose nerve was removed during treatment. So that in appearance they do not differ from all elements jaw arch, the product is injected into the pulpless cavity and acts on the tissue from the inside.
To achieve this result, the patient will have to visit the doctor more than once. After all the preparatory procedures, the product is injected into the cavity, which is then sealed with a temporary filling. After a certain period of time, the dentist evaluates the effect of the whitening components, and according to this, he performs a repeat procedure or completes the course.
Lightening of nonvital units was first proposed in 1864, but the desired effect was achieved only recently. In the 70s of the last century, endobleaching began use aqueous solution sodium perborate. Until this time, all lightening components were used as independent means and were constantly replaced.
Today, the technique of performing the procedure and the drugs for it have changed. They still contain the previously used substances, but in a different ratio, and the water has been replaced with hydrogen peroxide.
Changes in the tooth surface (discoloration) occur due to external influences, problems with general health, and is also caused by dental actions.
Darkening occurs due to:
The named factors, together or separately, have a detrimental effect on the shade of the elements of the jaw row. In addition to changes in color and loss of healthy shine, deposits accumulated on the surface provoke the development of various pathologies.
The correction for this type of darkening is simple - you need to abandon the actions that caused the darkening, devote enough time to hygiene and carry it out correctly.
This group includes the following states:
Iron sulfites in the blood permeate the dentinal canals, which also leads to a change in the appearance of individual elements. This staining will be more pronounced if the pulp is completely destroyed.
In this state, scratches and cracks quickly appear, through which food dyes, nicotine and bacteria easily penetrate into the internal tissues. They speed up the process age-related changes colors.
Changes in color from the inside are also caused by unprofessional actions of the doctor and some features of the materials used:
The reasons given are indications for performing intracanal clarification.
Based on the reasons that provoked a change in the shade of the teeth from the inside, it is advisable to carry out endobleaching in the following conditions:
The dentist decides how justified intra-canal bleaching will be for the given indications after assessing the degree of darkening and identifying the cause of this process.
Before deciding on the procedure, the patient should be aware of the limitations under which bleaching using this method is not recommended:
Intra-canal lightening shows a poor result on a “dead” unit with a long-standing composite filling.
In case of internal darkening, endobleaching is considered gentle alternative option prosthetics.
In addition, there are other advantages:
A disadvantage is the increased fragility of the element that has been clarified. If the procedure is performed repeatedly (more than four times a year) with a short time interval, there is a possibility of its destruction.
Also considered negative are:
The first thing endobleaching begins with is preparing the patient’s oral cavity. First, a visual and instrumental inspection is carried out.
X-rays are required. Based on its results, the doctor determines the nature and severity of the problem, determines the process diagram, checks the quality of fillings placed long ago and examines the tooth for the presence of a latent form of inflammation.
The next visit begins with the patient being asked to rinse his mouth with an antiseptic to eliminate bacterial infection.
The main phase of intracanal bleaching takes place in the following sequence:
A week later the process is repeated again. To get the desired result, the patient will have to visit the dentist 2 to 4 times at the same time interval. When will the tooth become desired color, a permanent filling is installed.
Important! To avoid destruction of dental tissues (resorption), a person needs to come for an examination once a year and have an x-ray taken.
The video shows a diagram of intra-canal teeth whitening.
Multiple studies by specialists from the Department of Dentistry of SSMU named after. Razumovsky confirm that the efficiency of intra-channel clarification is 83%.
The result may be worse if contraindications were not taken into account before implementation and the individual characteristics of the body influenced.
During the procedure, only some patients may experience weak sensitivity and a feeling of fullness in the treated unit. The effect obtained after the procedure lasts for a year, then it is recommended to repeat the procedure.
As statistics show, the number of patients resorting to this technique is growing every year. The demand for it is explained by the fact that when carried out, the bleaching agent acts on one specific unit, maintaining its shape and without damaging neighboring elements.
A possible complication of endobleaching is the fragility of the hard tissues of the problem unit. A similar consequence occurs if products with a higher concentration were used for lightening.
The need for their use is explained by the strong darkening of the non-vital element, on which the action of gels with a conventional composition is ineffective. For this reason, it is not recommended to carry out this procedure more than 4 times.
Dentists warn that if the tooth was initially weakened, then after whitening there is a possibility of its rapid loss.
A very rare consequence is disease of the gum tissue adjacent to this unit. It develops only when an infection occurs during the procedure.
Since the technique for performing endobleaching differs significantly from the surface method, the recommendations for the patient will be different.
In the future, you should take into account that a whitened tooth is not as reliable and durable as all the others. Therefore, you need to be more careful with it while eating.
Don't neglect daily hygiene. You should also brush your teeth twice a day, but with a paste that does not contain abrasive components. To prevent plaque formation, use rinses and floss.
Cost of endobleaching per unit in different clinics differs, but on average such a procedure will cost 1 thousand rubles. Price full course, consisting of several visits, is in the range of 8-10 thousand rubles.
The price includes:
