Abstract

Oral compositions containing a polyorganosilsesquioxane particle, preferably polymethylsilsesquioxane particles having a particle size of from about 1 to about 10 microns and an orally-acceptable carrier. Method of using such compositions for the cleaning and polishing of dental enamel, such methods including the step of applying such oral care compositions to the teeth of a user.

Description

technical field [0001] The present invention relates to oral care compositions comprising abrasives, and methods of using these compositions for cleaning and polishing teeth. Background technique [0002] Effective oral compositions maintain and protect the appearance of teeth by removing tooth stains and polishing teeth. It also cleans and removes external debris, which can help prevent tooth decay and promote healthy gums. [0003] Abrasives in oral compositions aid in the removal of the firmly adherent film to which dental stains adhere. The pellicle typically consists of a thin covering of acellular glycoprotein-mucin that adheres to the enamel within minutes of tooth cleaning. The presence of various food pigments present within the film is responsible for most of the various instances of tooth discoloration. Effective abrasives remove films with minimal abrasion to oral tissues such as dentin and enamel. [0004] In addition to cleaning, it is also desirable for ab...
