Abstract
A brush head including a housing, detachably securable to a handle of a powered toothbrush. A camshaft extends through a cavity defined in the brush head. The camshaft is operatively engaged with a motorized drive shaft in the handle and causes independent movement in tuft blocks provided on a head region of the brush head. Bristle tufts extend outwardly from each tuft block and through an opening defined in the head region. The rotating camshaft causes a first tuft block to reciprocate linearly in a plane disposed at right angles to the longitudinal axis and causes the second tuft block to oscillate about an axis parallel to the housing's longitudinal axis. The bristles on the first block chisel particulate material from the surfaces of the teeth being cleaned; and the bristles on the second block sweep particulate material from those surfaces.
