Cosmetic dentistry
Teeth whitening is the process of returning discoloured teeth to a brighter shade using hydrogen peroxide, a key ingredient in whitening products. This compound reacts with the enamel or within the tooth to lighten it. It suits people with yellow or discoloured teeth caused by stains or by their natural colour.
Whitening does not damage the tooth structure or make the enamel brittle. Some temporary tooth sensitivity may occur during and shortly after the procedure, but it usually eases within one to two days.
