Teeth whitening

Teeth whitening is used to correct discoloration of the teeth by removing the brown and yellow staining. Dark teeth can be whitened with a peroxide formulation which bleaches the enamel and makes your teeth whiter. The dentist makes custom plastic trays to fit your teeth exactly, which allows you to apply teeth whitening gel at home. It usually takes one to three weeks to achieve maximum results. However, existing fillings cannot be bleached.
