Abstract
A dental prophy cup comprises a flexible body having a cavity formed therein. A rear end of the cavity includes a paste reservoir for storing an abrasive paste. Paste-delivery channels extend forwardly from the reservoir and intersect front and rear circumferentially extending paste-distribution channels. Under the action of centrifugal force occurring during a tooth-cleaning procedure, paste is fed forwardly along the delivery channels and is distributed within the distribution channels. Between the channels is disposed a pattern of ridges which are capable of flexing relative to one another to conform to the shape of a tooth surface.
