ABSTRACT:
A method for whitening the teeth of a person, comprises the steps of a retainer made of a plastic material adapted to be moldable when heated for conforming to the shape of one of the upper and lower teeth of the person; heating the retainer until soft and moldable without losing its basic shape; fitting the retainer around one of the upper and lower teeth; applying a layer of tooth whitening composition inside the retainer; wearing the loaded retainer for several hours each day until the teeth to be whitened have become whiter; replacing the tooth whitening composition every 1-2 hours; and repeating the above steps with another retainer for the other of lower and upper teeth.
