ABSTRACT:
An oscillating toothbrush is disclosed in which an offset brushing head is integrally attached to a shank, the shank being housed with a two piece cylindrical handle. A pair of opposite pin surfaces cooperate with internally enclosed helical slots to provide an oscillating up down movement as the toothbrush moves across the surface of the teeth. The handle is provided with a rear stop surface cooperating with the end of the shank at which there is also located an apparatus of smaller diameter than the end of the shank in order to permit cleaning of the insides of the oscillating toothbrush.
