Abstract:

A toothbrush having three section including a head section having bristles, a handle section for griping the toothbrush and a connecting section for connecting the head section to the handle section. In two embodiments the head is parallel to but offset from the longitudinal axis of the handle so that the connecting section and handle do not interfere with the anterior teeth. This allows perpendicular contact of the bristles with the lingual surface of the posterior teeth and the gingiva. The handle is offset above the head so that the connecting section and the handle do not obstruct the view of the lingual surfaces of the posterior teeth while they are being cleaned. A third embodiment, the head at an angle to and is offset below the longitudinal axis of the handle. The bristles are of equal length so that when they are placed perpendicular against the lingual surfaces of the posterior teeth and the gingiva, the connecting section and the handle are away from the anterior teeth and the connecting section and the handle do not obstruct the view of the lingual surfaces of the posterior teeth while they are being cleaned.
