You may be surprised to know that many of the stains that darken teeth are not found on the surface of your teeth, but at the interface between your teeth’s enamel (it’s non-vital sheath) and dentin (the living tooth structure).
Teeth whitening (also called tooth bleaching or dental whitening) is a process that lightens dark appearing teeth and the discolored enamel and dentin. Studies show that proper use of a dentist monitored whitening system is an effective method of enhancing your smile. Almost anyone can benefit from tooth whitening.
