ABSTRACT:
An improved dental instrument for use in cleaning teeth, the instrument having a polishing cup with a self-contained abrasive and a system for automatically supplying a cooling fluid to the polishing cup when the cup is rotated; the cooling fluid serving the additional purpose of lubricating the cup driving mechanism, thereby eliminating the need of packing the driving mechanism in grease and allowing the instrument to be sterilized between uses.
