The toothbrush has an elongate member (50) extending between two ends. The elongate member (50) has a head (5) at one of its ends. The head (5) has a plurality of tufts (10) comprising a multiplicity of bristles (20). The tufts (10) have proximal ends (11) attached to the head (5), distal ends (12) extending outwardly from the head (5) and sides extending between the distal and proximal ends (12). The distal ends (12) of the tufts (10) are angled downwardly from a peak so the adjacent tufts form a V-shaped profile when looking at the side of the tufts. The tufts (10) are arranged on the head (5) so as to define outer tufts (18), adjacent the outer perimeter of the head (5), and inner tufts (19). A predetermined number of the outer tufts (18) have their peaks extending further away from the head (5) than all of the peaks of the inner tufts (19) so as to provide improved inter proximal penetration. |
