Full Answer

Fifteen to 78 percent of patients using hydrogen peroxide on their teeth will experience tooth sensitivity due to the breakdown of enamel from the peroxides, according to the National Center for Biotechnology Information. Hydrogen peroxide-based whitening solutions and over-the-counter options remove surface stains, which can also remove and break down the enamel of the teeth. For this reason, dentists suggest using professional products, in-office whitening options or whitening agents approved by and bearing the seal of the American Dental Association. Lower amounts of peroxide exposure are recommended to reduce the chance of enamel breakdown and tooth sensitivity.

Hydrogen peroxide can be used on its own as a whitening option to remove coffee stains, tea stains and berry stains. This can be used as a rinse or applied directly to the teeth. If these options are used, they should be followed by a mouthwash or water rinse to remove the peroxide.
