How Does Teeth Whitening Work?

by Natalie (SU)

First off, there is a difference between teeth whitening and teeth bleaching. Whitening involves removing the surface stains on your enamel with a mild abrasive. The color of your teeth will not be whiter than their original color, but whitening can remove stains from coffee or other foods and drinks that leave teeth yellow and dull.


Teeth bleaching, on the other hand, makes your teeth whiter than they ever were. The bleaching agent penetrates through the enamel and into the dentin of each tooth. It reacts with the substances there that are making the tooth appear darker and bleaches them white. Bleaching is what most people think of when they hear “teeth whitening”.


Both whitening and bleaching have been shown to be safe, in moderation. It is the most common cosmetic dental procedure. The active ingredients in most of today’s bleaching systems is called carbamide peroxide. Some treatments have a higher concentration of this bleaching agent, but although they work faster to whiten teeth, they do not actually make teeth whiter than gels with lower concentrations. You simply get your desired result more quickly.


As many kinds of teeth whitening systems are available over the counter, one major advantage of treatments available only in your dentist’s office is that you get faster results. The bleaching agent can cause sensitivity when it gets on your gums, so trusting the experience of your dental professionals to keep it only on your teeth practically eliminates the possibility of tooth sensitivity caused by teeth whitening. From custom molded trays to fit your teeth, to precision painting befitting a renaissance master, your dentist specializes in the health and appearance of your smile.


Teeth whitening can help you look and feel great with a whiter and brighter smile than you ever had before. Whether the stains on your teeth were caused by drinking coffee, smoking, taking medication, or just getting older, teeth whitening is a safe and effective way to get a beautiful smile.
