    • The present invention relates to a toothbrush with uniform diameter bristles containing a polishing agent with a particle size of from about 0.01 mu m to about 100 mu m, wherein cleaning of the teeth is improved without any of the adverse side effects associated with over aggressive abrasion. An embodiment of the present invention includes a toothbrush including a handle associated with a head having at least one tuft securely affixed in or attached to the head, said tuft including a plurality of filaments comprised of (a) a thermoplastic filament base material and (b) an effective polishing amount of a polishing agent having a particle size of from about 0.1 mu m to about 10 mu m. Particles less than 0.1 mu m can be used if aggregation occurs such that the aggregate size on bristle is as described. Another embodiment of the present invention includes a method of cleaning the oral cavity comprised of: (A) providing a toothbrush including a handle associated with a head having at least one tuft securely affixed in or attached to the head, said tuft including a plurality of filaments comprised of (a) a thermoplastic filament base material and (b) an effective polishing amount of a polishing agent having a particle size of from about 0.10 to about 10 microns; (B) applying an effective amount of an abrasive-free and polishing agent-free dentifrice to the free ends of said bristles; and, (C) brushing the teeth, gums, etc. of said oral cavity.
