Abstract
A prophy cup shield is cylindrical in shape and attaches to a dental handpiece by way of elastic fit around the nose of the handpiece. The inside of the shield includes novel spiral tracks which cooperate with the rotating cup to force any trapped paste that may find its way between the cup and the shield back out over the rim of the rotating cup. The shield prevents the splatter of cleaning paste and patient bodily fluids. The shield also prevents against accidental injury to the patient's gum because when in use the shield extends beyond the circumferential rim of the rotating cup.
