ABSTRACT:
A rocker toothbrush is disclosed wherein the brushhead includes three bristle tuft bundles, each on a separate, elongated base. The middle bundle is elastically hinged to the two side bundles, which, in turn are hinged to the brushhead. A force applied to the middle bundle, during normal use, causes the two side bundles to turn in the direction toward the middle bundle.
