ABSTRACT:
A toothbrush having one or more wheel members with radially disposed bristles adapted to roll into contact with tooth surfaces. End plates on the wheel member inhibit bristle deflection. In a multiple wheel member version an intermediate wheel member serves to confine bristles against displacement. Side plates carry a spindle for the wheel member or members. A curved guard extends partially about the wheel members.
