A composition and method for bleaching teeth is disclosed wherein red dye is dissolved in a solvent and combined with an inert, inorganic carrier. The composition is mixed chairside by the dental practitioner, with a source of active oxygen to form a bleaching paste, which is applied to prepared teeth. Teeth coated with the paste are then exposed to light of a visible wavelength range of from 400-550 or an argon laser. When the active oxygen is spent, the bleaching paste on the teeth turns colorless. The red dye greatly accelerates the bleach time.
