1. A toothbrush, comprising: a) an elongated handle having a rigid top member extending from an end thereof; b) a rigid plastic perimeter frame, said frame defining an opening extending through a central portion thereof, said frame bonded to a surface of the top member; c) an elastomeric field material within the opening of the frame and bonded to an inner surface thereof, the elastomeric field material including a first surface facing the top member and an opposite second surface, the second surface of the elastomeric field material having a plurality of bristles fixed to and extending therefrom, the first surface of the elastomeric field material being spaced from the top member in a rest position to define a void space there between; d) a longitudinal pressure equalizer disposed in the void space between the elastomeric field material and the top member; and e) whereby the bristles readily conform to both convex and concave surfaces by equalizing bristle pressure.
