Abstract
An apparatus for tooth stain removal is presented. The invention comprises a powered device with a chisel tip at its distal end, a body at its proximal end and an electric motor housed within the body for driving the chisel tip. The chisel tip has a proximal end removably coupled to the body and an exposed distal end along a generally longitudinal axis. The chisel tip comprises a pointed end on a first side for cleaning area between teeth and a broad cleaning surface on a second side for cleaning the main surface of each tooth. The chisel tip operates in a reciprocating motion driven by the electric motor. The reciprocating motion repeatedly moves the chisel tip in a back and forth direction by a finite displacement along the chisel tip's longitudinal axis.
