A disposable prophy angle for mounting on a powered dental handpiece with an elastomeric grip where the elastomer of the grip is disposed along the back of the neck, the back of the shoulder, and about the base of the device so that the prophy angle may be comfortably grasped by the fingers and thumb of a user, so that it will resist slippage from the user's hand, and so that it will tactilely direct the user's fingers and thumb into the proper position to handle the prophy angle in an effective manner.
