ABSTRACT:
A toothbrush designed for use by orthodontic patients. The toothbrush head includes first conventional bristle tufts on one face, but further includes a lengthwise channel on the opposite face. The bottom face of this channel includes transverse second bristle tufts, and from the side faces of the channel depend interdigitating third bristle tufts, while third bristle tufts depend from the remainder of this face of the toothbrush head. Accordingly, the second and third bristles will be able to reach out small cavities about the braces worn by the patient's teeth, while the fourth bristles will clean tooth portions adjacent the braces. The teeth scrubbing action of the second, third and fourth bristles occurs concurrently in a single toothbrush stroke.
