Crest Whitestrips | Teeth Stains Removal at Home

A stain on the tooth's outside is referred to as an extrinsic stain. These stains settle on your enamel, the coating of the tooth that guards the dentin, the softer part of the tooth, underneath. Even though the enamel is the toughest layer of the tooth, it is in constant touch with food and liquids and can eventually absorb some of the colors, staining the tooth. The good news is that extrinsic stains can be more easily removed since they don't penetrate past the enamel to the interior portion of the tooth.
