What does teeth whitening involve?
Teeth whitening is still one of the most expensive procedures. And recently it has become especially popular because prices have fallen a bit. Everyone wants a white snow smile. But not everyone knows what harm such a desirable procedure does.
This was told by the leading dentists:
According to them, there are various methods of bleaching, and they all have different effects on the teeth.
The chemical method is the effect of atomic oxygen on enamel. Gums for the procedure are treated with a special protective gel. The procedure is aggressive, and if the substance gets on the gums, you can get a serious burn. The laser method is more efficient and safer because the laser acts separately on each tooth. The ultrasonic method is the softest method because the heating of the tooth enamel and tissue is minimal.
Blue light teeth whitening is a fairly new method. The hydrogen peroxide gel is activated by the halogen light of the lamps and under the influence of light oxygen is released from the gel, which breaks down the dark pigment. Although there are a lot of options, all have a negative effect on tooth enamel. In particular, teeth whitening cannot be people with sensitive enamel or gum disease. People who have metal crowns can whiten their teeth only after consulting a doctor.
After regular bleaching, the teeth become weaker and the enamel becomes thinner. Therefore, many then experience hypersensitivity during eating or brushing teeth or bleeding gums. Bleaching can even lead to slow tooth decay. Therefore, after the procedures, teeth should be strengthened with special pastes.
But how safe are modern methods of professional teeth whitening?
Careful and numerous studies conducted by clinical trials prove that modern methods of teeth whitening, used by dentists, are safe for patients. Of course, if all conditions are kept. In compliance with the protocol of the procedure, careful identification of contraindications and the choice of whitening method, the hypersensitivity of the teeth passes through 1-3 days after the procedure.
Here is an example of how one of the bleaching procedures goes:
Whitening begins with a careful examination of the oral cavity. The dentist listens to the wishes of the patient and determines the indications and contraindications for whitening. Then, after the special preparation of the oral cavity, the doctor proceeds to apply the whitening gel on the teeth and activates it with a special light source.
