Abstract

A composition for desensitizing a hypersensitive tooth, comprises an effective amount of charged polymeric particles in a preparation for application to the surface of said tooth to cause desensitization of said tooth. polystyrene microparticles may be used in the method in which the composition is applied to the tooth surface. The method may comprise applying to said surface a sufficient amount of charged polymeric particles to block exposed tubules in the dentin layer of the tooth.
