ABSTRACT:
A dental prophy cup includes a polishing surface formed by a plurality of annular ridges spaced along a longitudinal axis of rotation of the prophy cup. Each ridge includes a generally forwardly facing side which has a micro-cellular texturing capable of retaining abrasive paste. The cup is molded of a solid elastomeric material in a mold which forms the micro-cellular texturing on the polishing surface.
