<p>The present invention relates to a U-shaped toothbrush, which remarkably reduces time and efforts required to brush teeth as the narrow plane, the tongue plane and the occlusal plane of teeth are brushed at the same time. Also, food residue stuck between bristles can be easily cleaned, thereby keeping the toothbrush hygienically. The own elasticity due to a U-shape allows to be deformed to correspond to the size or shape of teeth, thereby simultaneously contacting the bristles with the narrow plane, the tongue plane and the occlusal plane of teeth regardless of the size or shape of teeth, and the toothbrush is elastically deformed to correspond to the height of the occlusal plane with vertically different heights, thereby performing effective tooth brushing. The U-shaped toothbrush according to an embodiment of the present invention has a U-shape so as to simultaneously brush the narrow plane, the tongue plane and the occlusal plane of teeth, and comprises a head unit formed by connecting multiple U-shaped head members, in which bristles are vertically planted along the inner side, by a connection member, and a handle unit connected to the head unit as one body. Furthermore, the connection member is preferably formed to be lower than the height of the U-shaped head members so that cleaning discharge grooves are formed between U-shaped head members on both sides, and the connection member of the toothbrush head unit is formed with an elastic material capable of elastic deformation.</p> |
