ABSTRACT:
A toothbrush which provides superior cleaning as well as gum and inter dental stimulation. The toothbrush has an elongated member extending between two ends. The elongate member has a head at one of its ends. The head has a plurality of tufts comprising a multiplicity of bristles. The tufts have proximal ends attached to the head, distal ends extending outwardly from the head and sides extending between the distal and proximal ends. The distal ends of the tufts are angled downwardly from a peak so that adjacent tufts form a V shaped profile when looking at the side of the tufts. The head further includes a number of additional bristles attached thereto and extending above the peaks of the tufts. Alternatively, the tufts of bristles may include a predetermined number of bristles that are stiffer than the rest.
