    • Abstract:
      The number of Americans on a quest for whiter teeth has skyrocketed over the last few years. A recent survey found that 80 percent of adults aged 18 to 49 said that they would like to have whiter, bright teeth. Over the past five years, the demand for tooth bleaching has increased by more than 300 percent. New technology is being perfected to meet that demand. The oldest method of tooth lightening at home is the "nightguard" technique. A custom-fitted plastic mold is filled with a 3 percent peroxide solution that stays on the teeth overnight. Results are often mixed. Some teeth that are gray or grayish brown do not lighten as well as those that are yellow or yellowish brown. Stains caused by tobacco smoke, coffee, and red wine also require more time to lighten. The effects are always temporary. INSET: Untitled.
