Supersmile is the ONLY whitening toothpaste clinically proven to remove stains from artificial tooth surfaces, such as bondings, veneers, caps, crowns, and dentures as well as professionally-bleached teeth and braces. Because it doesn't penetrate the tooth surface, opening the enamel rods and dehydrating teeth, it won't cause sensitivity. And without harsh abrasives, it won't compromise enamel.
