Professional whitening, done by your dentist in Denver is the safest, and the most effective option for best results. Because superficial stains must be dealt with before whitening, your dentist in Denver will examine and clean your teeth, and determine if you are a good candidate for whitening.
The external covering of the tooth, the enamel, has a clear finish, but underneath there is a layer of dentin, which is usually yellowish in color, and shows through the enamel. The whitening process uses a peroxide blend, painted onto the enamel. This coating seeps through to the dentin, and lightens it, producing the whitening effect.
