Oral Care Compositions and Methods for the Same

Abstract

A film forming composition and methods for preventing acid erosion of teeth and preventing the formation of caries on teeth are disclosed. The film forming composition may include a hydrophobic copolymer, a fluoride compound, and an orally acceptable solvent. The film forming composition may also include a cellulose derivative, a rosin, a fluoride compound, and an orally acceptable solvent.

Description

BACKGROUND[0001]Conventional oral care products are often utilized to deliver fluoride to surfaces of the oral cavity to thereby prevent the formation of caries. For example, fluoride containing toothpastes and mouthwashes are often utilized to deliver or apply fluoride to surfaces of teeth, thereby preventing the formation of caries. The efficacy of fluoride in preventing the formation of caries, however, is partially determined by the ability of the fluoride to maintain contact with the surfaces of the teeth. As such, the efficacy of fluoride delivered to surfaces of the teeth via conventional oral care products (e.g., mouthwashes and toothpastes) is generally unsatisfactory, as the fluoride is often easily removed from the teeth by either physical or chemical processes. For example, fluoride on the surfaces of the teeth may be physically removed by chewing and / or chemically removed by prolonged exposure to the varying temperatures and pH levels of the foods and drinks we consume....

AI Technical Summary

Benefits of technology

The present patent provides a film forming composition for preventing the formation of caries on teeth. The composition includes a hydrophobic copolymer, a fluoride compound, and an orally acceptable solvent. The composition can be applied to the surface of the teeth using a method described in this patent to prevent acid erosion. The technical effect of this invention is the prevention of dental caries and acid erosion on teeth surfaces.

Problems solved by technology

As such, the efficacy of fluoride delivered to surfaces of the teeth via conventional oral care products (e.g., mouthwashes and toothpastes) is generally unsatisfactory, as the fluoride is often easily removed from the teeth by either physical or chemical processes.

While conventional tooth varnish compositions incorporating fluoride demonstrate relatively increased efficacy in preventing the formation of caries as compared to conventional oral care products, they are often highly viscous and slow to dry, which results in the formation of a tacky or sticky coating, which is unpleasant and undesirable.

Further, conventional tooth varnish compositions may often utilize natural resins that tend to form relatively thick films having a yellowish tint, which may make the teeth appear stained.
