A survey by the American Academy of Cosmetic Dentistry found that 74% of Americans believe an unattractive smile can hurt someone's career opportunities. Many Americans also falsely believe that white teeth means healthy teeth. However, even white teeth can have cavities or Periodontal Disease. Before beginning a whitening regimen it is important to have an exam by your dentist. Whitening should only begin once it is certain there is no tooth decay or gum disease.
What is in tooth whitening? Most whiteners contain hydrogen peroxide. The peroxides help remove deep (intrinsic) stains and superficial stains. The most common side effect of peroxide bleaching is sensitivity. The soft tissues of the mouth can also be disturbed. It is important to review the different forms of bleaching with your dentist so that the best method is chosen for you.
