急速に生じるようにすることができる。A similar toothbrush, manual or mechanical, is disclosed in DE 3,706,345. According to this toothbrush, the brush head can flex when a certain contact pressure is transmitted to the brush handle, and in this way, the optimal contact pressure for brushing teeth can be maintained. . This flexible part is formed in the shape of a leaf spring and can be bent or angled, and the flexible part is provided with a longitudinal crack in the center, which increases the contact pressure and increases the contact pressure. If this happens, the brush head can be moved from its initial extended state to a deflected position with respect to the longitudinal axis of the handle. This means that brushing your teeth any further is, if not impossible, at least quite difficult. Deflection can occur gradually and then rapidly beyond a breaking point.
