Removal of surface stains from enamel surfaces with at-home vital bleaching: a case report.

Stone model casts of a patient's maxillary and mandibular arches were used to fabricate a clear, soft, vacuum-formed custom mouth guard that was scalloped to end 1.0 mm supragingivally. The patient was given prophylaxis and oral hygiene home care instruction, and instructions regarding the placement of an at-home bleaching gel into the mouth guard and the mouth guard into the mouth. The patient was asked to wear the mouth guard for two hours daily before bedtime for one week and to return to the clinic for evaluation. This protocol was followed for three weeks for each arch. At the end of the three weeks, the stains on the most affected teeth were reduced dramatically.
