摘要 A toothbrush is provided with a first set of discrete tufts (31) that are generally rectangular in the cross section perpendicular to the tuft axis with the larger dimension running parallel to the side of the brush head (1). A second set of tufts (32) is provided at the end of the head (1) remote from the handle, this set of tufts, or single tuft, having a cross section perpendicular to the tuft axis that is either 'C' or 'U' shaped or rounded. The arrangement of bristle tufts described provides a lower brushing stiffness in a direction transverse to the longitudinal axis of the brush.
