The toothbrush with a refillable storage chamber (24) for a free-flowing dental cleaning agent in the handle (10) and a manually operated pump (30) for conveying portions of dental cleaning agent through a connecting channel (26, 28) to the bristles, possesses an exchangeable bristle head (14). This merely comprises a plate (40) carrying the bristles (50), so that only a very small part has to be discarded once the bristles are worn, whereas the handle (10) and the stem (12), as well as a fitting protective sheath (16) are retained for a long time. <IMAGE>
