- Do Tooth Whitening Products Really Work?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I have noticed a lot of advertisements for a new type of tooth
- paste that claims to actually whiten your teeth. The type of programs that
- promote these products always make me suspicious, so I thought I would write
- and ask your opinion. Do these products really work, how do they work and are
- they safe to use? Your comments would be most appreciated.

- ANSWER: The tooth pastes you refer to use a method that does make teeth
- whiter through a bleaching process. Most of them use a type of chemical known
- as an "oxygenating agent" that actually bleaches the discoloration out of the
- tooth, removing the color much as a laundry bleach removes dirt from clothing.
- In the case of these tooth paste products, the most commonly used chemical is
- a 10 percent concentration of carbamide peroxide, which, when it comes in
- contact with the fluids in the mouth, is transformed into hydrogen peroxide
- that releases the highly active form of oxygen that finally reacts with the
- teeth. As to the safety of these products, particularly over time, that is
- more difficult to answer. The American Dental Association (ADA) has expressed
- concerns about the safety of these products, and has asked the Food and Drug
- Administration (FDA) to investigate the problem. The ADA says there is not
- enough scientific data on the safety of the products, the manufactures of the
- tooth products say they are safe to use as directed, and the FDA is trying to
- decide whether these are cosmetic products or drugs, for which there are more
- stringent rules concerning safety and efficacy. These new products seem to be
- most useful in cases where the discoloration is mild to moderate, resulting
- from cigarettes, coffee food or aging, but severe discoloration that results
- from the exposure to certain antibiotics during the growth years is less
- likely to be affected. Some dentists offer treatments with similar products
- that have the advantage of being used under supervision, and the disadvantage
- of being costly and time consuming.
