Who should not use OTC tooth whiteners?

If you have very sensitive teeth, you should avoid OTC tooth whiteners. The bleaching agents can cause pain and may make your teeth even more sensitive. You should also avoid OTC tooth whiteners if you have gum disease, crooked or damaged teeth. OTC whiteners won't bleach crowns or veneers, so it you have them and you whiten your teeth, you could end up with "Technicolor teeth:" natural teeth that are white and restored teeth that aren't. Avoid OTC tooth whiteners if you're pregnant or nursing, since any whitening bleach you swallow could be harmful to your unborn or nursing baby.
