The Atlanta Journal-Constitution stated that although “tea, red wine, and blueberries” may provide health benefits, they may also contribute to teeth changing color. The article noted that several options for whitening teeth are available, adding that even for mild stains, “it’s a good idea to check with your dentist before beginning any whitening process.” Dentists “can help you distinguish between intrinsic (internal) and surface (extrinsic) stains,” the article stated, noting that intrinsic stains can “only be corrected by a dentist.” The article also provided several tips to prevent staining and discoloration, recommending regular dental visits, brushing and flossing daily, avoiding tobacco products, and limiting beverages that contributing to staining, such as coffee, tea, and soda.
MouthHealthy.org provides additional information on what causes teeth to change color and also on teeth whitening. In addition, several whitening toothpastes and a whitening product have the ADA Seal of Acceptance.
Whether you choose over-the-counter or professional tooth whitening, talk it over with your dentist to make sure you’re informed. It’ll save you time, money, and possibly problems.
