Over the past several years, more and more people have chosen to whiten their teeth with over-the-counter whitening products. That probably comes as no surprise. After all, we are bombarded day after day with images of celebrities with picture-perfect smiles, and who wouldn’t want to have a movie star smile? But some people have become obsessive about bleaching their teeth, and when it comes to whitening products, too much of a good thing is really, really not good. In fact, over-whitening your teeth can put your oral health in danger. This problem has become so common that dentists have coined the term “bleachorexia” to describe it.
As is the case for most things in life, moderation is the key. Whitening your teeth in moderation is totally safe. If you follow the directions listed on the package with regard to how often to whiten, you shouldn’t have a problem. Unfortunately, many people ignore those directions altogether in favor of having extremely white teeth. While the ingredients in teeth whitening solutions are completely safe when used as directed on the packaging, over-using them can damage the enamel of the tooth surface and cause gums to recede. Ironically, people with damaged enamel actually end up with a more yellow tinge to their teeth since the tooth surface under the enamel is not nearly as white as the enamel itself. Once the enamel is gone, it can’t be replaced, and no whitening product will change the color of the yellow tooth surface underneath the enamel. So over-whitening your teeth can actually lead to more yellow teeth!
Whiten Your Teeth the Sensible Way
If you choose to whiten your teeth, you should know that over-the-counter whitening products don’t work nearly as well as whitening kits purchased from your dentist. There are two reasons for this: 1) your dentist will usually provide you with a custom-made tray to use with the whitening solution, which will allow the bleach to come into contact with more of the tooth surface; and 2) the whitening agent itself is typically much stronger than any OTC product. The fact that over-the-counter products don’t work as well might actually be the reason that so many people are over-whitening. To avoid this situation altogether, it’s best to purchase your whitening product from your dentist, and to follow his or her directions with regard to how often to use the product.
Most dentists offer their patients two varieties of whitening products: those that are administered in the dentist’s office, and take-home kits that the patients can use at their convenience at home. Usually, the most effective results are produced by first having your teeth whitened in the dentist’s office, then following up periodically by using a whitening kit at home.
For more information about whitening your teeth safely, talk to your dentist. Whatever you do, don’t fall into the “bleachorexia” category. If you do, you could harm your gums and ultimately end up with yellow teeth!
