Abstract
A toothbrush which is particularly well adapted for properly cleaning tooth surfaces and interproximal areas having a plurality of tufts of bristles mounted in the head of the toothbrush with the tufts cut in a series of at least two rounded peaks extending laterally across the head and in which the tufts of bristles may be arranged in at least two longitudinally disposed outer rows defining an inner area lying therebetween and at least one longitudinally disposed inner row is positioned in the inner area, with the tips of the inner row of tufts of bristles being feathered.
Claims21
