## Abstract

Methods and compositions for reducing, (e.g., controlling, inhibiting, preventing, protecting against, or minimizing) staining, (e.g., resulting from stains and/or discoloration) of teeth in the oral cavity are provided. Aspects of the compositions include a component or components (e.g., a wax and an oil) capable of reducing staining of the teeth. In some instances, the compositions further include an agent which enhances the mineralization of teeth.

## Claims

### Claim 1

A method for reducing staining of a tooth in a subject, the method comprising:
(i) applying a composition consisting of a bee's wax, a coconut oil, and optionally a mineralizing enhancement agent to the tooth in a manner sufficient to produce a temporary coating of the composition on the coated tooth; and
(ii) contacting the coated tooth with an agent capable of staining teeth such that staining of the tooth by the agent is reduced.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the reducing comprises controlling, inhibiting, preventing, protecting against, or minimizing staining of the tooth.

### Claim 3 (depends on 1)

The method according to claim 1, wherein staining is manifested as the occurrence of stains and/or discoloration of the tooth.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the composition further includes a mineralizing enhancement agent.

### Claim 5 (depends on 4)

The method according to claim 4, wherein the mineralizing enhancement agent comprises a calcium phosphate.

### Claim 6 (depends on 4)

The method according to claim 4, wherein the mineralizing enhancement agent comprises a fluoride.

### Claim 7 (depends on 1)

The method according to claim 1, wherein the composition is applied in the form of a coating.

### Claim 8 (depends on 1)

The method according to claim 1, wherein the agent comprises a beverage, food item, or smoke.
