Abstract
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.
Claims29
A bleaching composition comprising carrier particles comprisina an inert, non-toxic, inorganic material, and adsorbed on the carrier particles an effective amount of a mixture of at least two red dyes responsive to light that accelerates teeth whitening to decrease the time to bleach a tooth when the composition is exposed to light in the presence of active oxygen.
A bleaching paste for teeth whitening comprising
- a) a source of active oxygen, and
- b) a bleaching composition comprising carrier particles comprising an inert, non-toxic, inorganic material, and adsorbed on the carrier particles, an effective amount of a mixture of at least two red dyes responsive to light that accelerates teeth whitening to decrease the time to bleach a tooth when the bleaching paste is exposed to light in the presence of active oxygen,
- said bleaching paste being red in color when applied to the teeth and becoming nearly colorless when the bleaching process is completed.
A kit including
- a first sealed container holding a predetermined quantity of a bleaching composition comprising carrier particles, and on the carrier particles is adsorbed an effective amount of a mixture of at least two red dyes responsive to light that accelerates teeth whitening to decrease the time to bleach a tooth when the composition is exposed to light in the presence of active oxygen;
- said first container having a predetermined volumetric capacity sufficient to hold from 0.25 to 1.00 ounces of the bleaching composition, and being filled to at least 50 percent of said predetermined volumetric capacity,
- a second sealed container holding a predetermined quantity of a liquid providing a source of active oxygen,
- said first sealed container being adapted to serve as a mixing vessel in which the contents of the first and second containers are mixed to form a bleaching paste to be applied to a patient's for teeth for whitening.
A method for bleaching teeth comprising
- applying to a tooth a bleaching paste including (a) a source of active oxygen, and (b) a bleaching composition comprising carrier particles comprising an inert, non-toxic, inorganic material and adsorbed on the carrier particles an effective amount of a mixture of red dyes responsive to light that accelerates teeth whitening to decrease the time to bleach a tooth when the composition is exposed to light in the presence of active oxygen, and
- exposing the tooth to light.
