Abstract
A brush head for a motor-driven toothbrush includes a multitude of bristles and a plate shaped bristle support to which the bristles are attached. The brush head is connectable to a motor-driven toothbrush for oscillatory rotation and translation. The bristle support is divided into several bristle support segments that are movable relative to each other. In particular, diametrically opposed bristle segments are tiltable on a shared tilt axis or on separate tilt axes arranged in a plane perpendicular to the axis of rotation of the brush head.
