Abstract
A prophylaxis cup is provided which has a lower portion and an upper portion. The lower portion of the cup is adapted to mount the cup to a driven member of a prophylaxis angle. The upper portion of the cup includes a wall having an inner surface and an outer surface. The inner surface is smooth and uninterrupted and defines a cavity having a floor and which receives prophylaxis paste. A central post extends up from the cavity floor. A continuous, uninterrupted, circumferential flange extends inwardly from a top of the wall's inner surface. A sloped working surface extends between the flange inner edge and the wall outer surface. The cup is pre-formed to define a flare or annular wedge at the outer edge of the working surface which is sized to permit the working surface to clean a tooth subgingivally and interproximally. A generally circular groove on the working surface helps hold the prophy paste. The groove spirals outwardly.
