Initial evaluation. A cross-polarized picture is taken to better asses the extent of the lesion. It is decided to start a bleaching therapy to try to minimize the contrast between the spots and the tooth.

IMPORTANT:Bleaching trays must be extremely precise, cervical sealing should be perfect in order to keep the bleaching product in place and safe of intraoral moisture.
