Abstract
A toothbrush which automatically provides an up-down stroking action in concert with a side-to-side stroking action as the brush is stroked side-to-side along the teeth of a user. The brush incorporates two pairs of elongate bristle-carrying pads with the pads of each pair positioned side-by-side and the pairs end-to-end. Each pad is hinged to the pad-holding end of the brush with the hinge axis being angularly related to the elongate axis of the pad. The hinge comprises a relatively thin elongate web having a substantially hour-glass cross-sectional shape.
