No! the American Dental Association (ADA) and the Food and Drug Administration (FDA) have approved the use of peroxide for over-the-counter use. Our customers perform the teeth whitening (sometimes called teeth bleaching) procedure on themselves. Since our products are all self-administered, either by the chairside method or by our take home products, it is no different procedurally from what they can perform on their own. We never give them dental advice, and we never represent ourselves as dentists. We do recommend that our customers visit their dentist regularly and if they do not, we will advise them not to whiten their teeth until they have done so.
