Methods for whitening teeth
First Claim
1. A tooth whitening method comprising:
- applying to at least one surface of one or more teeth in place in an oral cavity an oxidizing composition comprising an oxidizing agent in an oxidizing agent fluid carrier, wherein the oxidizing agent consists of hydrogen peroxide and the oxidizing agent fluid carrier consists of water and ethanol;
thereafter applying a separate sealant composition without an oxidizing agent directly onto one or more teeth surfaces having the oxidizing agent thereon, wherein the sealant composition comprises a water-resistant polymer dispersed or dissolved in a sealant fluid carrier, the water-resistant polymer consisting of one or more modified cellulosic polymers, silicone polymers, urethane polymers, polyamide polymers, vinyl polymers, or mixtures thereof; and
maintaining the sealant composition in place on the teeth surfaces for a sufficient time to permit the sealant fluid carrier to evaporate and form a coating on the teeth surfaces that resists moisture contamination of the previously applied oxidizing agent.

Abstract
Compositions and methods for whitening the teeth of a patient or subject include the application of at least one tooth whitening composition having a viscosity of at least 100 centipoise to the surface of a stained tooth, accompanied by the application of a sealant composition that forms protective film or coating on the tooth surface to resist moisture contamination of the oxidizing composition. The whitening procedure can be further enhanced by removal of acquired pellicle from the tooth surface prior to application of oxidizing and sealant compositions. The novel procedure allows for a high degree of tooth whitening by protecting the oxidizing composition while it is in contact with the tooth surface.

15. A tooth whitening method comprising:
-
applying to at least one surface of one or more teeth in place in an oral cavity an oxidizing composition comprising (i) an oxidizing agent in an oxidizing agent fluid carrier, wherein the oxidizing agent consists of hydrogen peroxide and the oxidizing agent fluid carrier consists of water and ethanol, and (ii) at least one component with a non-tooth whitening function; thereafter applying a separate sealant composition without an oxidizing agent directly onto one or more teeth surfaces having the oxidizing agent thereon, wherein the sealant composition comprises a water-resistant polymer dispersed or dissolved in a sealant fluid carrier, the water-resistant polymer consisting of one or more modified cellulosic polymers, silicone polymers, urethane polymers, polyamide polymers, vinyl polymers, or mixtures thereof; substantially avoiding contact of the oxidizing agent with saliva prior to the step of applying the sealant composition; and maintaining the sealant composition in place on the teeth surfaces for a sufficient time to permit the sealant fluid carrier to evaporate and form a coating on the teeth surfaces that resists moisture contamination of the previously applied oxidizing agent. - View Dependent Claims (16)
