Oral care products comprising buffer systems for improved mineralization/remineralization benefits

Abstract

Oral products for the improved mineralization / remineralization of teeth are provided. In an embodiment, the present disclosure provides an oral product comprising a calcium salt, a phosphate salt, a sodium salt and a potassium salt. For example, the molar ratio of the sodium salt to the potassium salt ranges from about 3 to about 4.

Description

[0001] priority [0002] This application claims priority to US Provisional Patent Application Serial No. 60 / 765,289, filed February 3, 2006, the entire disclosure of which is hereby incorporated herein. Background of the invention [0003] The present disclosure relates generally to dental care. More specifically, the present disclosure relates to oral care products that improve mineralization / remineralization of teeth. [0004] The enamel and dentin in teeth are mainly composed of calcium phosphate in the form of calcium hydroxyapatite. The material is highly insoluble at the neutral pH level of saliva, but readily dissolves in acidic media. Thus, when a tooth is exposed to the acids produced during bacterial glycolysis of carbohydrates, areas of damage or demineralization initially appear beneath the surface of intact enamel because the outer edges are more resistant to acid. Dental caries starts from these subsurface lesions, which form before cavities can even be found...

AI Technical Summary

Problems solved by technology

If left untreated, the superficial enamel overlying this subsurface damage will eventually collapse, causing cavities to form and subsequent loss of tooth structure
