Experts say to remember the following when choosing a tooth whitener:

  • The ADA recommends discussing the options with your dentist and choosing a dentist-supervised whitening plan.
  • Bleaching effectiveness is directly related to the percent of peroxide and length of time it's in contact with your teeth. Over-the-counter tooth-whitening products generally contain no more than 10% peroxide. Professional teeth-whitening processes can use up to 43% peroxide.
  • Bleaching works best for yellow teeth, not as well for gray teeth.
  • Crowns, fillings and dental veneers are not affected by lightening products -- something to keep in mind if you have a prominent crown or bridge.
  • For best results, have your teeth professionally cleaned to remove surface stains before beginning a whitening treatment.
  • Using desensitizing toothpaste before and after whitening can help to reduce sensitizing effects. For more information, see our report on toothpaste.
