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.

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
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; andmaintaining 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. 2. The method of claim 1, further comprising removing the coating. 3. The method of claim 1, further comprising performing a dental prophylaxis by cleaning and scaling teeth in the oral cavity, including the one or more teeth having the oxidizing agent and coating in place, in proximity to at least one of a gum line, gingival margin, and crevicular space while avoiding excessive disruption of the coating. 4. The method of claim 3, further comprising performing the following steps after performing the dental prophylaxis: applying another oxidizing composition comprising a fluid carrier and an oxidizing agent to one or more of the teeth having been cleaned and scaled while performing the dental prophylaxis; andthereafter applying another liquid sealant composition to one or more teeth having the other oxidizing agent thereon, wherein the other sealant composition comprises a fluid carrier and a water-resistant polymer, and forms a coating that resists moisture contamination of the previously applied oxidizing agent in the other oxidizing composition. 5. The method of claim 1, further comprising performing a dental prophylaxis by cleaning and scaling one or more teeth in the oral cavity prior to application of the oxidizing composition thereto. 6. The method of claim 1, further comprising removing acquired pellicle from the surfaces of the one or more teeth in place in the oral cavity before applying the oxidizing composition thereto. 7. The method of claim 6, wherein the removing step includes applying a conditioning composition including at least one tooth conditioner in a conditioner fluid carrier. 8. The method of claim 7, wherein the conditioning composition is separate from the oxidizing composition and the tooth conditioner is selected from the group consisting of phosphoric acid, hydrochloric acid, acetic acid, lactic acid, citric acid, EDTA, phytic acid, 1-hydroxyethylidene-1,1′-diphosphonic acid, and combinations thereof. 9. The method of claim 1, further comprising substantially avoiding contact of the oxidizing agent with saliva prior to the step of applying the sealant composition. 10. The method of claim 1, wherein the oxidizing composition is hydrophobic when in contact with the teeth surfaces. 11. The method of claim 1, wherein the oxidizing composition further comprises a water-resistant polymer. 12. The method of claim 1, wherein the oxidizing composition further comprises at least one component with a non-tooth whitening function. 13. The method of claim 12, wherein the component with a non-tooth whitening function is a tooth conditioner. 14. The method of claim 13, wherein the tooth conditioner is an organic acid. 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; andmaintaining 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. 16. The method of claim 15, wherein the component with a non-tooth whitening function includes an organic acid.
