As the number of tooth-whitening products on the market multiply so does the discussion on their safety.
Whether products are purchased over-the-counter, administered by your dentist, or dispensed by your dentist for use at home, there are two major categories: peroxide-containing whiteners or bleaching agents; and whitening toothpastes (dentifrices).
The most commonly observed side effects to hydrogen or carbamide peroxide are tooth sensitivity and occasional irritation of the soft tissues in the mouth (oral mucosa), particularly the gums. Tooth sensitivity often occurs during early stages of bleaching treatment. Tissue irritation, in most cases, results from an ill-fitting tray rather than the tooth-bleaching agents. Both of these conditions usually are temporary and stop after the treatment.
With years of accumulated data to support its position, the American Dental Association (ADA) has found tooth-whitening products to be safe and effective.
The ADA Council on Scientific Affairs grants its Seal of Acceptance to whitening toothpastes (dentifrices) containing polishing or chemical agents rather than bleaches. Bleaching products in the program contain 10 percent carbamide peroxide. Click here to do an ADA Seal Product Search.
