Before whitening your teeth, the practitioner detects possible cavities, makes fillings and redoes those that he considers not tight enough. Indeed, it is essential that the whitening gel cannot come into contact with the ivory of the teeth.
After scaling, he applies a cream designed to preserve the mucous membranes and the skin of the face.

The alternative is to apply compresses around the mouth. The neck of the teeth and the gums must also be protected before whitening the teeth. Once these steps have been completed, the dentist is ready to apply the whitening gel to the teeth. He uses a lamp equipped with a laser beam, which generates a light that helps open the pores of the enamel and facilitates the penetration of the photosensitive product.
