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 of the brush.
Brosse à dents munie d'un premier ensemble de touffes de soies séparées (31), en général rectangulaires selon une coupe dans un plan perpendiculaire à l'axe des touffes, et dont la dimension la plus grande est parallèle au côté de la tête (1) de brosse. Un second ensemble de touffes de soies (32) placé à l'extrémité opposée au manche de la tête (1) présente une coupe en C en U ou arrondie dans un plan perpendiculaire à l'axe des touffes. Cette disposition assure une dureté de brossage moindre dans le sens transversal à l'axe longitudinal de la brosse.
