Abstract
A toothbrush for cleaning individual teeth includes a longitudinally extending handle portion (10) connected to a curved head portion (20). The head portion (20) carries a plurality of relatively long, soft bristle tufts (31) arranged in transverse rows and a plurality of relatively short, hard bristle tufts (32) arranged in transverse rows sandwiched between the transverse rows of the plurality of relatively long, soft bristle tufts (31). The curved head portion (20) has a small radius of curvature of between 1.4 and 1.8 centimeters, optimally 1.5 centimeters, while the relatively long, soft bristle tufts (31) each extend radially from the curved head portion (20) by a distance of between 0.8 and 1.2 centimeters, optimally 1 centimeter. In this manner, the entire arrangement (30) of bristle tufts is made to converge substantially on the area of an individual tooth and its surrounding gum line.
