Who doesn't want a "movie star" sparkling smile? Many types of teeth whiteners are available, including whitening strips, whitening toothpastes and rinses, gels, trays, lights and lasers. What products might work for you? It depends upon the health of your gums, how many composite resin (white-colored) fillings or crowns you have, and the degree of discoloration of your teeth.
What Causes Tooth Discoloration?
As you get older, teeth naturally tend to darken. The American Academy of Cosmetic Dentistry says there are internal and external factors. Internal causes include tooth decay, restorations, trauma or the use of some antibiotics as a child. External reasons include eating foods with tannins, such as coffee, tea, red wine, carrots and oranges. Smoking also is a big factor in yellowing teeth.
