Full mouth toothbrush

Abstract

A full-mouth toothbrush may include a semi-elliptical channel confined between an outer semi-elliptical wall and an inner semi-elliptical wall conforming to contours of a set of teeth, a brush assembly mounted within the semi-elliptical channel with a first bristled brush head, a second bristled brush head, and a connecting rod coupled between the outer semi-elliptical wall and the inner semi-elliptical wall. The first bristled brush head and the second bristled brush head are rotatably mounted on the connecting rod and an actuating mechanism may actuate a rotational reciprocating motion of the brush assembly. The actuation mechanism includes a first pedal and a second pedal coupled to the brush assembly that may be actuated by opening and closing motions of a user's mouth and urge the brush assembly to assume a rotational reciprocating motion.
