Abstract: The present invention relates to a toothbrush with uniform diameter bristles containing a polishing agent with a particle size of from about 0.01 &mgr;m to about 100 &mgr;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 &mgr;m to about 10 &mgr;m. Particles less than 0.1 &mgr;m can be used if aggregation occurs such that the aggregate size on bristle is described.

Abstract: Elastomeric polymeric flosses comprising particulate modification agents stably associated with the surface thereof, as well as methods for their fabrication, are provided. In the subject flosses, particulate modification agents are either adsorbed to the surface of the floss or embedded in the surface of the floss. To fabricate the subject flosses, unmodified elastomeric flosses are contacted with particulate modification agents under conditions which provide for the stable association of the particles with the floss surface, where the floss surface may be softened to promote embedding of the particulate modification agents in the surface of the floss.
