Tooth Whitening
ooth whitening is a process that lightens discolorations of enamel and dentine without causing damage to the tooth surface. Mildly discoloured teeth respond better than darker stains such as those caused by antibiotics. Whitening has no effect on restorations such as fillings and crowns. The degree of whiteness will vary from patient to patient and will depend on the structure of the teeth and the period for which the product is applied.
