Tooth whitening products for use at home work over a short period of time but users should be aware of common side effects and note that long-term data on their use are not yet available.
Products for whitening teeth at home are available 'over-the-counter' or from dentists. This review looks at whether such tooth whitening products work and, if so, which are more effective. The review focuses on products which have a chemical, bleaching action rather than an abrasive action. Results found that over a short period of time these products do work, and that there are differences between the products, mainly due to the levels of active ingredients, hydrogen peroxide and carbamide peroxide. People should be aware of common side effects such as tooth sensitivity and irritation to the gums and note that long-term data on the use of such products are not yet available.
