At your initial consultation, the dentist will verify that you're a candidate for whitening, assess your shade and take impressions for your custom fabricated trays. Your in-office procedure will begin with prep and the first of four Zoom WhiteSpeed in-office whitening gel applications. The WhiteSpeed lamp will accelerate whitening so that each of the four sessions last only 15 minutes. Post treatment you will receive your fabricated trays, one DayWhite or NiteWhite take-home whitening gel syringe.
