ABSTRACT:
The present invention relates to a toothbrush which exhibits superior interproximal and gingival margin cleaning. The toothbrush includes an elongated handle member connected to a toothbrush head member. The head is divided into two regions. A "toe" region is defined as the part of the head which is furthest from the handle and a "heel" region is the portion of the head which is closest to the handle. A multiplicity of bristles extend from the heel region of the head; the distal ends of these bristles form a longitudinally aligned concave shape when viewed on end. Likewise, a multiplicity of bristles extend from the toe region of the head, wherein said bristles extending from the toe portion of the head are at least as tall as the general height of said bristles 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 of from 0.degree. to about 45.degree. declining from the edge of the toe portion distal to the heel portion to the edge of the toe portion which is proximal to the heel portion.
