“Wedge” for the wisdom tooth. What myths about fillings are still strong

The word “filling” is familiar to everyone who regularly treats teeth and undergoes examinations at the dentist. After all, this is one of the most common types of repairs after certain manipulations. So, for example, after eliminating even a small caries, the doctor will put a filling.

At the same time, despite the fact that a person can have many fillings – both 8 and 9, etc. – anyway, he is sometimes ready to believe myths. Some of the misconceptions lead to a delay in the treatment process or the choice of the wrong methods on the part of the patient to care for his teeth, which causes the loss of teeth altogether.

About what myths about fillings are still tenacious, AiF.ru told dentist, chief physician of the dental clinic Ilya Antonov… “First of all, we need to figure out where the myths about fillings come from. This is often associated with stories that came to us from the period when dentistry did not reach the modern level of development of equipment, technologies, properties and qualities of materials. Today it is possible to treat those teeth that were previously only removed. If we compare the filling material in the early 90s and now, this is heaven and earth, ”notes Ilya Antonov.

According to the dentist, modern compamer filling materials have greater strength, better adhesion to the tooth tissues, a wide range of colors, allowing the restoration of damaged areas with an accurate selection of the color of the filling to the tissues of your tooth. Modern technologies have allowed new filling materials to expand the indications for their use and improve the quality of the restoration. Therefore, the dentist often has to deal with the ideas of patients who were pumped from the past and have already become myths or delusions.

Myth one: once a seal is installed, it must last a lifetime.

The opinion that a filling should live forever is one of the most common. “Patients do not think that their tooth tissue, which is much stronger than a composite filling, can no longer withstand their chewing load. How can a plastic seal, even if it is made of modern material, stand in such conditions without being erased all its life? No way, ”says Ilya Antonov.

You also need to understand that the filling is placed in a decayed tooth, which has lost its integrity, says the dentist. The damaged area of ​​the tooth is the one where the maximum chewing pressure fell. Therefore, it collapsed. “Before placing the filling, the affected tissues were drilled out of the tooth, thereby making the walls around the filling in the tooth even thinner. In this case, the filling, filling the cavity of the tooth, begins to work as a “wedge”, which accounts for the chewing pressure. This pressure is transmitted by it to the surrounding walls, and over time, the walls of the tooth begin to collapse, ”the dentist notes. In this case, the filling itself is erased due to the fact that the opposite tooth, covered with enamel, which is much harder than the filling material, presses on it, the specialist emphasizes. In this case, the annual scheduled examination by the dentist allows you to assess the condition of the fillings in a timely manner and, if necessary, change them.

Myth two: modern materials can be used to make overlays on the front teeth, similar to veneers.

There is also an opinion that composites are becoming an excellent material for creating onlays on the front teeth, which will replace veneers and will last a long time. “First of all, you need to know that the filling material, even after very good polishing, remains porous on the surface. These pores can only be viewed under a microscope, and it is important to understand that bacteria are also small. Plus, over time, the composite is impregnated with organic matter from the oral cavity and swells slightly, thereby making the restoration object more visible, ”says Ilya Antonov.

At the same time, this does not happen with fillings that are located on the chewing surface of the tooth, since there the filling is always polished with the opposite tooth, says the dentist. “Therefore, the composite restoration of the anterior parts of the tooth is possible only in a small volume, and if it covers the entire surface of the anterior tooth wall from the outside, then such a restoration is temporary and it must be changed periodically (depending on the material swelling or its color change from the plaque penetrated into the structure of composites), and it is better to replace it with a more reliable and aesthetic veneer, ”the dentist notes.

Myth three: a tooth after filling should not hurt

Many people believe that after treatment and filling, the tooth should not hurt. In fact, this is not always the case. “In 2/3 of cases this is exactly the case, but there is very deep damage to the tooth, in which the filling is located close to the pulp chamber. In this case, the material, when pressed on it during chewing, transfers the load to the bottom of the cavity, which is already thin. Under this load, the bottom cannot adequately redistribute the resulting pressure over the dentin of the tooth, and part of it goes to the pulp of the tooth. In this case, a short-term painful sensation is possible, which disappears immediately. This is considered within the normal range, ”says Ilya Antonov.

The doctor, as a rule, explains to the patient that such sensitivity will pass over time, as the dental tissue adapts to new conditions, but the tooth takes time for this, the dentist says. Therefore, in no case should you stop chewing on it, but you should not overdo it. Otherwise, there will be a pulp injury from excessive pressure and the tooth will have to be depulpated, the doctor emphasizes.

The fourth myth: electric brushes and irrigators loosen the seals

Modern technologies have brought a lot of doubts and worries into human life. For example, people believe that active dental care using electric brushes and irrigators can ruin the situation with fillings.

“Here you need to know that a similar situation took place, but in a very short period of time. Then 2 factors coincided, the first composite materials with not the best physicochemical properties were on the market, and ultrasonic toothbrushes had just appeared, which worked at a wave frequency at which really old fillings swayed, ”says Ilya Antonov.

Brush manufacturers reacted to this problem very quickly by changing the frequency of the vibration wave to a more gentle one without losing the quality of cleaning, plus the properties of composites improved, and for a long time, for reasons associated with the use of electric brushes and irrigators, fillings do not fly out, says the dentist.

The fifth myth: a wisdom tooth is not filled

For many, wisdom teeth are an unpleasant defect that can only be removed. Therefore, people rarely decide on filling. But in fact, it is quite possible to put fillings on wisdom teeth. “They even get a filling, there is only one nuance with it – it should be normally located in the oral cavity, that is, normal access should be provided to it. These are, as a rule, the lower teeth and the upper ones in the case when the patient can open his mouth wide, and the doctor has the opportunity to work with the tip and instruments without strong restrictions in place, ”says Ilya Antonov.

Myth six: don’t eat for 2 hours after filling

The recommendation to restrict food after the filling procedure is still firm. And often people give it to themselves. “Before the doctor put a seal and said that you should not eat for 2 hours. Now this limitation is due only to the fact that we use anesthesia for treatment. The patient after it does not feel part of the cheek and lips. Having started to chew in this state, the patient risks biting something to himself. Therefore, I always say that you can eat right away, as soon as the anesthesia is gone, ”says Ilya Antonov.
