PATENT APPLICATION for CIRCULAR TOOTHBRUSH by Thomas Sung ABSTRACT OF THE DISCLOSURE A circularly movable mechanical toothbrush having a fly wheel type drive shaft loosely joined to a rod near one edge thereof. Actuation of the fly wheel causes the rod to rotate in a distinct motion that causes toothbrush bristles to be maintained at all times toward selected teeth, which motion compactingly massages gums during a gradual approach stroke, aligns the bristles with tooth striations and interdental spaces during a sweeping brush stroke, and keeps the bristles disposed away from the user's cheek during a return stroke. - 1 -
