Tooth filling – how it happens and how it should be. Is the tooth filling a cure-all or not?

What is more often asked by phone from the administrator of the dental clinic?

How much does it cost to have your tooth filled up? If the price suits you, it is recorded. If not, they call further on other oases of dentists. Such call does not take into account what kind of filling we are talking about, from what material will be made, the main thing is how this very filling will be put. We will try to understand and explain what on what. If you are interested, read for your health.

The filling of teeth is also called tooth restoration, tooth build-up. How should the filling of the tooth go? The option of express filling of teeth in 20-30 minutes will not be considered and you are not advised. This method of teeth treatment takes at least 40-60 minutes. And the maximum can be 2-2.5 hours.

Tooth filling - how it happens and how it should be. Is the tooth filling a cure-all or not?

First, the dentist makes anesthesia. Then, he removes all carious, diseased tissues of the tooth to be restored. If at this stage of treatment the tooth is tooth decay and leave the rudiments of caries, then in six months – a year the tooth filling will no longer meet the gold standard of quality or will simply fall out. Under it, tooth decay will continue its dark business, which will end either with pulpitis or loss of the filling.

Previously, the dentist decided on the complete removal of tooth decay easily – by eye. Nowadays, dentists use special preparations called tooth decay detectors. It is applied to the tooth to be restored. If its color is pleasantly pink, then everything is OK. If the color is different, then tooth decay is still nesting in this place. The dentist can see exactly where to do the additional dissection of the tooth to be restored.

Why such troubles? Isn’t it possible to remove more tooth tissue before filling the tooth? Yes. This is exactly what was once done, it was called “preventive expansion”. There is a common opinion among dentists that the more is left of the tooth, the better. We stick to this when filling teeth. In this, miracle fights help us. They process the tooth selectively – they easily remove cavities and have difficulty dissecting healthy enamel and dentin.

The tooth has been treated, it is possible to put the long-awaited filling of the tooth? No. If, of course, we want to get a decent result, the tooth filling is for a long time, almost forever. It is necessary not only to remove all tooth decay, but also to restore the tooth correctly.

The filling of teeth occurs in the mouth, where there is a lot of moisture. And the filling of the tooth is known not to like water during the filling. For this purpose, during the filling of teeth, the dentist isolates the tooth from moisture and saliva with the help of numerous devices: cofferdam, retraction threads, tooth wedges. Cofferdam – a rubber handkerchief that separates the future tooth filling from the rest of the teeth and saliva. It can also be liquid – it is applied around the tooth filling to the gum and cured with a special lamp. The retraction filament is inserted between the gingiva and the tooth to be filled, so that no moisture from the gingiva gets onto the tooth filling.

When it is necessary to restore the lateral surface of the tooth, the dentist has to be very tight – it is necessary that the filling of the tooth repeats its original shape and fits tightly to the neighboring tooth.

The tooth filling must exactly follow the shape of the tooth. Otherwise, the filling of the tooth does not touch the neighboring tooth – food will enter and the gum will be injured. Or – the food will not get stuck easily, but when it gets there, it will be impossible to get it. Even with a kilo of gum. Such a tooth filling will permanently traumatize the gum, there will be a chronic inflammation, the gum will turn red, it will bleed. And the periodontitis is not far.

How does a dentist work in the tight space between teeth? Do you want to put the material in excess and then remove the excess? This is only Tseriteli under force, and then only with sculptures. Therefore, a retraction filament is placed that moves the gum away so that it doesn’t get pinched and prevents moisture from entering the working field. Then a suitable matrix is placed, repeating the shape of the tooth to be restored and creating the shape of the future tooth filling. One or more wedges holding the matrix in place are selected so that the filling material does not leak between it and the tooth to be filled. There are complete matrix systems and retention devices that we use. We will not describe them separately – their principles and tasks are similar.

Only now can we begin to create a tooth filling directly. At the same time, modern light fillings require careful observance of the technology of their application, exposure, degree of drying, etc. Let us describe only the stages, without their explanation: etching, washing with distilled water, drying (without drying), application of adhesive, drying, polymerization with dental lamp. And only now it is the turn for the filling material, which is introduced not in one portion, but in parts, each of which is separately treated with the lamp.
