Nightguard vital bleaching: dark stains and long-term results.
Since its introduction to dentistry in 1989, nightguard vital bleaching has proven to be a simple and safe procedure for lightening discolored teeth. Efficacy of the technique is 98% for non-tetracycline-stained teeth, and with extended treatment time, tetracycline-stained teeth can be expected to lighten in 86% of cases. Satisfactory retention of the shade change without additional treatment can be expected in 63% of patients 3 years post-treatment and in at least 42% of patients at 7 years. Side effects are usually mild and transient, disappearing within days of treatment completion. Patients report that they are glad they went through the procedure and 98% recommend the procedure to a friend.
