In Office - Opalescence Boost, a 38% hydrogen peroxide power bleaching gel, offers brighter, whiter teeth after just one hour in the dental chair. Opalescence Boost is chemically activated, so it starts working as soon as it is placed on your teeth, and doesn't require a hot,
uncomfortable light for efficacy. A safe, dentist-supervised procedure, Opalescence Boost is the ideal choice for in-office tooth whitening.
