It is important to have an examination by a dentist to assess the condition of your teeth and determine the reason for the tooth discolouration to decide if bleaching will help you. A dentist’s role is also critical in educating patients about the safest way to bleach their teeth, and assess the effectiveness as well as treat any adverse effects. For example, bleaching gel has been shown to have minimal effects on white fillings, but can cause mercury release from silver amalgam fillings so it is important to avoid bleach contact with these teeth. In addition, it can damage the glaze on porcelain crowns or veneers.
