Combined professional and home care nightguard bleaching of tetracycline-stained teeth.

The effectiveness of combining in-office and at-home nightguard vital bleaching on tetracycline-stained teeth was evaluated. Grade 1 and grade 2 tetracycline stains were eliminated completely in two months by this combination approach. Grade 3 stains, the most severe, were lightened significantly with a reduction in the banding effect. The most common side effect was an increase in tooth sensitivity, especially to cold, while actively in treatment. All patients reported disappearance of the sensitivity after termination of the treatment phase.
