Abstract

A toothbrush head has several bristle support segments movable relative to each other, and driving elements that change the position of the bristle support segments relative to each other. The driving elements have a cam control surface that causes the individual bristle support segments to execute an additional movement superposed upon the movement of the bristle support.
