Opalescence Boost, an in-office whitening treatment, provides beautiful, long-lasting results. This whitening features a chemically activated formula that allows your dentist to whiten your teeth without heat or ultraviolet rays of a light. Opalescence Boost also contains potassium nitrate and fluoride, which help to improve oral health by strengthening enamel, decreasing sensitivity, and offering increased cavity prevention. The in-office procedure is safe and effective, and offers a brighter, whiter smile after one appointment.
