An improved toothbrush for cleaning teeth and simultaneously cleaning and stimulating gums, which comprises: a brush body having an elongated handle; the brush body having its width substantially perpendicular to the longitudinal axis of the elongated handle, the brush body being longest in width than its length; a plurality of bristles having first ends embedded in the brush body and second ends projecting therefrom defining a brushing surface, the brushing surface\s width being longer than its length; the brushing surface being so adapted to facilitate simultaneous selective application of more than one medication or the like; the brushing surface having two gum-stimulating portions, one disposed along each of its lengthwise edges that primarily contact the gums during horizontal brushing and a teeth cleaning portion that primarily contact the teeth during horizontal brushing, the teeth cleaning portion never extending below the gum-stimulating portions; and the gum-stimulating portions and the teeth portion being so configured that the brushing force results in a lower pressure on the gums than is on the teeth and the brushing surface having means for providing simultaneous contact of the upper and lower gums when the respective upper and lower teeth are contacted by the brush surface, and the brushing surface and handle having further means for providing an overturning moment when the upper or lower teeth are brushed requiring the toothbrush user, to push the brush surface in the buccal corridor to prevent the brush surface from rotating away from the teeth.
