ABSTRACT:
A toothbrush comprises a handgrip formed on one side with a substantially plane fingerrest and a concave thumbrest and on an adjacent side with a palmrest including a convex portion spaced apart from the thumbrest and a substantially linear portion adjacent to the thumbrest. A neck is connected to the handgrip, and a head is connected to the neck. The head is formed with a substantially plane wide oval-shaped bristle-supporting surface and includes soft flexible bristles extending outward from the bristle-supporting surface. The neck has an axis that is angularly displaced with respect to an extension of the linear palmrest portion through an acute neck angle, the angular displacement of the neck axis being clockwise for a right-hand brush or counterclockwise for a left-hand brush, as seen from the side of the toothbrush on which the fingerrest and the thumbrest are located. The bristle-supporting surface is angularly displaced with respect to the neck axis through an acute crank angle and with respect to the plane of the finger rest surface through an acute rotation angle. The angular displacement of the bristle-supporting surface is, in the case of the crank angle, counterclockwise for a right-hand brush or clockwise for a left-hand brush, as seen from the side of the toothbrush opposite the palmrest. In the case of the rotation angle, the displacement of the bristle-supporting surface is clockwise for a right-hand brush or counterclockwise for a left-hand brush, as seen from the head end of the toothbrush.
