Abstract

The present invention relates to a toothbrush which exhibits superior interproximal and gingival margin cleaning. The toothbrush includes an elongated handle member (12) connected to a toothbrush head member (14). The head is divided into a "toe" (20) and "heel" (22) region. A multiplicity of bristles (24) extend from the heel portion, the distal ends of these bristles form a longitudinally aligned concave shape (28) when viewed on end. A multiplicity of bristles (30) extend from the toe region of the head wherein these bristles are at least as tall as the general height of the bristels extending from the heel portion when viewed from the side and wherein the side profile view of the distal ends of the bristles extending from the toe portion form a generally linear surface which forms an angle relative to the general plane of the bristles extending from the heel portion.
