How Does Tooth Whitening Work?

If your teeth have become stained or discolored as the result of diet, aging, or hereditary factors, ask your dentist about tooth whitening in Kendall. Watch this video to find out more about how tooth whitening treatments work.

The presenter explains that red wine, coffee, and smoking can all stain teeth, as they contain chromogens or intensely pigmented substances which can adhere to tooth enamel, causing extrinsic (surface) stains. The video explains that extrinsic stains can be removed by brushing with a whitening toothpaste. However, if staining agents penetrate the tooth’s dentine layer, the resulting stains can only be removed by a dental professional. The dentist will apply a peroxide bleaching agent to the teeth. The presenter explains the peroxide can separate the large chromogen molecules into smaller components, which contain less pigmentation. This procedure can leave your teeth whiter than before.
