TREATMENT FOR DENTIN SENSITIVITY WITH AQUEOUS DISPERSIONS OFHYDROPHOBE-CO-HYDROPHILE COPOLYMERS

摘要

A desensitizing agent for the cleaning and treatment of sensitive teeth comprising a copolymer having repeating hydrophobic and hydrophilic regions. Preferred examples include polysoaps such as: a monovalent salt of a hydrolyzed copolymer of an .alpha.-olefin and maleic anhydride; e.g., structurally represented in Formula (I). When applied thereon by brushing or rinsing or other method of application, the copolymers occlude the tubules a nd seal them off from the external oral environment and thereby alleviate the pain caused by the tooth's sensitivity.
