The procedure is simple but requires great care on the part of the professional who performs it.
First of all, the type of colouring of the teeth must be assessed in order to know what degree of white we can realistically achieve. There are stains that cannot be removed, such as those caused by tetracyclines.
The teeth are then impregnated with the concentrated whitening gel and activated with the LED light. The gel is exposed to the light for 15 to 20 minutes on the teeth. One to three procedures are performed with a break between them in the same session.
IT IS A VERY SAFE PROCEDURE AS LONG AS THE INDICATIONS ARE STRICTLY FOLLOWED AND IT IS SUPERVISED BY A PROFESSIONAL.
A poor evaluation of the health of the gums and teeth, an excess of concentration or application time must be avoided, as they can end up producing hypersensitisation of the teeth, alterations of the enamel or irritation of the mucous membranes. It is therefore necessary that it is carried out in the clinic.
