ABSTRACT:
A shaft is formed with a curved neck. The long axis of an oval brash head at the end of the neck is approximately perpendicular to a handle region of the shaft. Four semi-circular rows of bristles and two relatively straight rows of bristles project from the brush head at approximately right angles to the handle region. Two of the semi-circular rows are proximal to the handle and define a generally convex brushing surface. The other two semi-circular rows are distal to the handle and define a generally concave brushing surface. The two relatively straight rows are medial to the concave and convex brushing surfaces and define a generally planar brushing surface.
