Abstract: A toothbrush comprising an elongated handle, a bristle support member articulately mounted on one end of the handle so as to be constrained, in use, into limited reciprocal movement with respect to the handle and in a direction of longitudinal axis of the handle. The toothbrush further comprising a plurality of bristle tuft arrays pivotally mounted on the support member about at least one pivotal axis substantially parallel to the longitudinal axis and articulately coupled to the one end of the handle so that the limited reciprocal movement of the support member gives rise to limited pivotal lateral rocking of the bristle arrays.
