Filling of teeth

What is tooth filling knows, it seems, every person. However, only in general terms. Let's try to figure out what is going on with this procedure.

Filling of teeth begins with the fact that the doctor makes anesthesia to relieve the patient of pain. After that, he carefully removes all affected tooth tissues. This stage is very important, because It is enough to leave at least insignificant remains of tooth decay - and after a maximum of a year the seal will have to be changed. At first, the quality of caries removal directly depended on the doctor's experience, but now modern technologies allow to accurately estimate its quantity with the help of special detectors, which are applied to the tooth. Thanks to them, you do not have to remove obviously more tissues teeth, so that probably there are no tissues infected with caries.

After the removal of diseased tissues, the doctor isolates the tooth from moisture (because the seals must be dry during the installation) with the aid of special devices (rubber cofferdam headscarf, dental wedges or retraction threads). And only after carrying out all these manipulations the doctor starts to do directly tooth filling.

What are the fillings for the teeth?

When a person turns to dentistry with the question of how much it will cost a tooth filling, he still does not think about what kind of seal he will put, and about the fact that the cost of filling depends on this choice.

First, the seals are divided into temporary and permanent. Temporary, as the name suggests, is put for a period. This is necessary in order for the dentist to determine whether the nerve is damaged or in order to put a medicine under it. Permanent seals are placed for a minimum of several years, and ideally - for decades.

Constant seals are made of different materials.

1.Metallic. Are made of alloys of metals with mercury. It is believed that tooth filling with such seals is very reliable, especially if the alloy is of high quality (with silver). Such seals are 20-30 years old, unless, of course, another foci of caries is formed next. However, the installation of such seals takes quite a long time, because They dry out for about 3 hours. Another drawback is the visibility, you can not put such a seal on the front teeth.

2. Cement. They also differ in composition. Most often there are phosphate and glass ionomer. Phosphate fillings can now be safely called a relic of the past. They strongly abrade, fall out and do not fit well to the edges. Their service life rarely exceeds a couple of years. Therefore now in any decent stomatology such seals to you will not offer. Glass ionomer fillings are somewhat more durable and their composition inhibits the development of caries. However, their quality, too, leaves much to be desired, so they are used mainly for sealing baby teeth or put under the crown.

3. One more kind of short-lived and gradually leaving in the past seals - plastic.

4. Composite fillings are divided into several subspecies:

- Acrylic fillings are very strong, but they often cause secondary caries and pulpitis.

- fillings with a base of epoxy resins are less toxic, but wear out more quickly and darken over time. Therefore, if you need to fill the front teeth, do not use such seals.

- Light - cured fillings last about 5 years. It is these seals that are considered the most modern. When exposed to ultraviolet light, they gradually polymerize, which allows them to form their shape and choose a shade.

5. One more modern way of sealing is the tabs. With this method of sealing, an impression is made from the hole in the tooth, and then, according to it, something like a prosthesis made of metal, porcelain or plastic is made. Then the prosthesis is attached to the tooth. The disadvantage of this method can be called a high price.

In the event that caries has passed into the pulpitis, the root canals will also need to be sealed, which remain empty after removal of the nerve. Materials for sealing the root canals are quite diverse, their choice depends on the recommendations of the dentist and the amount you are willing to pay.
