8 things we should know about tooth whitening

The teeth whitening is an aesthetic treatment to clarify the tone of the teeth that counts, each time, with greater demand. The darkening of the teeth occurs with the passage of time due to enamel wear and even beating in the denture can cause color changes.

What does it consist of?

It is the application of a peroxide-based gel that penetrates through the dentinal tubules and generates a reduction and oxidation reaction with which the bonds of the internal pigments of the tooth are broken. In this way, the tooth becomes clear of color.

When would it be indicated and in what cases?

Each case must be assessed individually, but in general terms it can be said that it is indicated in all those who want to improve the appearance of their smile by clarifying the tone of their teeth. It could be said that the contraindication is in cases of very severe functions as a result of the intake of certain antibiotics in childhood, such as tetracycline’s, since whitening will not be able to correct these cases, or in cases in which the anterior teeth are restored. The restorations do not change color and after the bleaching of the natural tooth, a lot of contrast can be seen with the restoration materials.

It is safe?

Yes it is, although at a higher concentration of the peroxide gel may appear tooth sensitivity, which is usually reversible as soon as the treatment is finished.

Do I have to take some special precautions?

In cases of people with very sensitive teeth it is convenient to increase the revisions so that they do not become a problem.

Results more progressively. Ambulatory or clinic

How much does it cost (more or less)?

It depends on the query; not being a health treatment, clinics play a lot with these treatments for strategic and marketing reasons, but more or less around $ 300.
