Whitening the teeth can give a profound improvement to the smile. It is the most cost effective and pro-health procedure for a cosmetic improvement. Often I start our patients out with an In-Office Bleaching procedure that takes about an hour. The person continues with at-home whitening strips over a 30 day period. Then the patient returns and we make a decision if another In-Office Bleaching is needed. Some patients may not be able to whiten more due to their enamel translucent level.
