Teeth Whitening is a safe and effective way of achieving a brighter smile. This can be done in two ways: in chair whitening or a custom made home whitening kit. Both options are available at our office. The treatment works through the introduction of a whitening gel to the surfaces of the teeth and they break down the superficial stain molecules that make the teeth appear dark and dull. In chair whitening is administered by a dentist to ensure careful and safe handling of the material during treatment. Home whitening kits are custom made for the patient: this uses a customised whitening tray inserted in the mouth for the delivery of the whitening material to the teeth surfaces.
