Teeth whitening involves a chemical reaction that penetrates the enamel of the teeth to bleach stains below the surface. Hydrogen peroxide or carbamide peroxide may be used. In either case, these chemicals work their way into the porous parts of the enamel to bleach stain deposits in the dentin, which is the layer just below the enamel. Teeth whitening at a dental office is hastened through the use of special lights that accelerate the bleaching process.
