Abstract: A device which fits onto a dental hand piece providing a spinning polishing cup at an angle to a long axis of the hand piece. A dental practitioner may use the device to effectively clean and polish teeth and prosthodontic structures within a patient's mouth. The device is disposable for greater sanitation. The device rotates in a direction in conformity with other fittings for dental hand pieces. The device is designed for easy manufacture by snapping a long gear and a short gear into contact with each other within a housing. Low friction secure interfaces between the short gear, the long gear and the housing allow the device to operate effectively at high speeds.
