5. Assuming all teeth are the same
Do you know if it’s safe to bleach all of your teeth? “Some patients aren’t sure if they have porcelain crowns or veneers in their mouth. Applying whitening products to them can remove the surface glaze, or the shiny part of the restoration and make them look worse,” says Albert. Your dentist can tell you if you have these restorations in place, and provide advice on how to safely whiten the neighboring teeth.
