The toothbrush of the present invention comprises an elongated handle having a head attached to one end. The head has a bristle-bearing face having longitudinal perimeter portions adjacent longitudinal edges and at least two perimetric, elastomeric massaging elements alternately arranged with groups of bristle tufts along each of the longitudinal perimeter portions. The brush can comprise further massaging elements which are not located along the longitudinal perimeter portions though the use of such additional elements is preferably minimised.
