ABSTRACT:
A dental device for removing stains from teeth which includes a housing easily maintained, manipulatable, and operable in one hand of an operator. The housing includes a head member having a first internal chamber and a longitudinally extended handle member defining a second internal chamber. A motor is mounted within the first internal chamber of the head member and is directly connected in rotative displacement to a rubber cup stain removing element which is coupled to the motor external to the housing head member. In one form of the dental device the motor is electrically connected to a pair of batteries which are mounted within the second chamber of the handle member. Operation of the motor is provided by a switch which passes external to the housing and is actuated by one finger of the operator. When actuated, the switch completes an electrical path between the batteries and the motor in order to generate rotative displacement of the rubber cup which serves as the stain removal mechanism from the teeth of the user.
