Teeth whitening occurs as a result of the oxidation of enamel coloring pigment - in essence, this process is similar to hair bleaching with hydrogen peroxide. Although modern whitening agents are gentle, the tooth tissue loses some of its minerals. The mineral composition of the teeth can be restored with the help of dental remineralization and fluoridation procedures. You can sign up for procedures on the website of the network of clinics Good dentistry.
In most cases, the enamel is restored over time, but some people develop increased sensitivity of the teeth and the hardness of the tooth tissue decreases.
Is it possible to fight it somehow? And what to do with those whose teeth already have increased sensitivity - will they really give up the "Hollywood smile"?
Dental remineralization
Restoration of the mineral composition of enamel is called remineralization. In dentistry, special compounds are used for this, which saturate the tissue of the teeth.
Enamel consists of more than 40 chemical elements, 97% of which is calcium. Therefore, this macroelement must be present in remineralizing compounds. Fluorine belongs to microelements - this means that its content in the body is very small. And in the enamel itself, it accounts for about 0,15%. However, it is difficult to overestimate the importance of this mineral for our teeth. It plays a major role in the formation of enamel and dentin, and also activates remineralization processes, "attracting" other minerals to the tooth tissue. The structural substances of enamel (apatites), which were formed with the participation of fluorine, are significantly harder and more resistant to the effects of acids. Therefore, fluorine is the second element that is usually used in professional enamel restoration procedures. The best result is given by the joint use of these substances.
If fluoride and calcium are used during remineralization, the procedure takes place in 3 stages:
-
Preparation Pollution interferes with the penetration of calcium and fluoride ions into tooth enamel. Therefore, the doctor first of all cleans the surface of the teeth from plaque and hard deposits. Then the teeth are treated with hydrogen peroxide and thoroughly dried.
-
Saturation with calcium ions. The doctor applies tampons soaked in calcium solution to the surface of the patient's teeth for 20 minutes, changing them every 5 minutes.
-
Saturation with fluorine ions. A five-minute application of a fluorine-containing liquid is performed.
The delivery of minerals can also be carried out by a physiotherapeutic method - with the help of microcurrents. But this method is used less often.
It is desirable that the remineralizing substances remain on the surface of the teeth as long as possible, so it is necessary to refrain from coarse food for about 4–5 hours.
Fluoridation
This is a procedure for saturating the tooth surface with fluoride ions. Fluoridation is simple and deep.
Simple fluoridation
The technique consists in applying a fluoridating substance to the enamel. This is done in two ways - with the help of a brush or a special mouthpiece ("spoon").
The procedure with the use of a brush is very simple - fluoride varnish is applied 3-4 times every other day.
The use of mouthguards is more complicated, but also effective. First, an impression of the human jaw is taken, and a mouth guard is made based on this model in the dental laboratory. Then, at each session, it is filled with fluorogel and put on the patient for about 15 minutes. The procedure is repeated every 10 days 10–15 times.
Simple fluoridation is an inexpensive and accessible technique. However, it has a minus - fluorine ions act only in the surface layers.
Deep fluoridation
This procedure is more complicated and expensive, but also more effective. Fluoride penetrates much deeper than when using a simple technique, and its concentration is 5 times higher.
In the process of deep fluorination, two layers are successively applied. The composition of the first includes calcium fluoride and magnesium fluoride, and the second - calcium copper hydroxide. These substances enter into a chemical reaction, resulting in the formation of calcium fluoride particles that crystallize in the deep layers of tooth enamel.
After deep fluoridation, you can eat and drink.
Important! Before fluoridation and remineralization, a professional teeth cleaning is mandatory.
Each of the described procedures has proven itself well and will help you restore the enamel structure after whitening. However, if the enamel is initially too thin, perhaps the doctor will recommend other ways to make your smile snow-white - for example, the installation of veneers.
