Tray tooth bleaching involves the use of carbamide peroxide in a custom-fitted tray to bleach teeth. One of the most difficult stains to bleach is tetracycline. This paper will present several different patient situations of tetracycline-stained teeth being bleached and will discuss the benefits and limitations of bleaching tetracycline-stained teeth. By providing the patient with realistic potential outcomes of bleaching, as well as the preservation of tooth structure and cost-benefit ratio of bleaching compared to veneers or crowns, the chance for a successful acceptance of the outcome is better, even if the outcome is less than ideal. Bleaching before prosthodontic treatment can also provide a better outcome for subsequent veneers or crowns if that is possible, but sensitivity may preclude bleaching.
