ABSTRACT OF THE DISCLOSURE A toothbrush for controlling brushing-stroke comprises a brush portion studded with bristles; a handle portion extending from the brush portion; a cavity associated with the handle portion for defining a space; and a moving member placed within the space for reciprocally moving within the space by reciprocal movement of the toothbrush and for hitting an end of the space and making a continuous hitting sound when the brushing-stroke of the reciprocal movement of the toothbrush is longer than a predetermined value. The use of the present toothbrush will reduce the brushing stroke until the continuous hitting warning sound ceases to perform the so-called "Bass' method" or "scrubbing method".
