Patent ID: 6851153

Claim:
A toothbrush which comprises: a rounded handle and a head on one end of said handle having a) a longitudinally elongated face, b) a back flat side of the head opposing the face, and c) a plurality of bundles of bristles embedded in said head and projecting from said face and terminating with a free end cumulatively creating a bristle end contour arranged in five to eight longitudinal rows in transversely spaced relation and with the bundles in each row being longitudinally spaced, there being two outboard rows, one on each side of the longitudinal length of the head, and the remainder of longitudinal rows are classified as inboard rows, the bristle bundles in the outboard rows having uniform heights to lightly engage the gums of the teeth being scrubbed and the bristle bundles in the inboard rows having variable heights that simultaneously mate with and scrub a group of adjacent teeth, the longitudinally elongated face of the brush head being contoured to similarly match the bristle end contour of both outboard and inboard rows thereby presenting a mirror image of a group of adjacent teeth to be scrubbed, whereby humans can thoroughly brush their dentition more efficiently with greater bristle contact and force, at the same time yielding less harm to the teeth and gums.
