ABSTRACT:
A mechanically or electrically operated toothbrush is actuated by a reversing switch operated by a movable handle section mounted over the housing of the toothbrush. The direction of the rotation of the toothbrush is changed by movement of the handle relative to the housing while the brush is applied to the teeth to provide the desired direction for the section of teeth being brushed.
