We use the Pure whitening method, which involves a combination of dental practice whitening and at-home whitening. The patient applies the gel at home using custom-made trays. After two weeks of nightly at-home whitening, the patient comes in for an in-office whitening session. This may be followed by additional at-home daily 2-hour whitening or proceed directly to the maintenance phase, which is ideally practiced approximately every 3-4 months for one night at a time.
