In the present invention, disclosed is a tooth crusher which comprises a collision unit with a certain height in a crushing container and a filter mesh having an iron mesh on an upper end portion of the collision unit and can crush a tooth into an implantable material in a uniform size to crush an extracted tooth or a bone piece into a uniform size or a uniform diameter needed for treatment of teeth. The tooth crusher comprises: a main body (50)； the crushing container (20)； a cutter (30) which is located in an accommodation unit of the crushing container (20), is joined to a motor, and is rotated； and a cover (10) joined to an upper end portion of the crushing container (20). The tooth crusher comprises a filter mesh (60) which is located in the accommodation unit of the crushing container (20) and covers a rotation area of the cutter (10). The filter mesh comprises: the collision unit (62) with a certain height； and the iron mesh (61) which is formed on the upper end portion of the collision unit (62) and has holes in the same size. Since the tooth crusher has the collision unit with the filter mesh, time of coming in contact with the cutter is increased. Consequently, the tooth crusher crushes an implantable material within a short time. The tooth crusher has a barrier function, prevents a raw material, having passed through the iron mesh, from colliding with the cutter, consequently prevents the raw material from being crushed into a smaller size, and thus can manufacture the implantable material in a uniform size. Compared to a conventional technology wherein a filter mesh is arranged on a lower end portion of a crushing container, work time is reduced by 30-50% and uniformity of the size of the implantable material is increased by 50-60%.본 발명은 발치한 치아나 뼈 조각을 치아 치료에 필요한 크기나 직경을 일정하게 분쇄하기 위하여, 분쇄통 내부에 일정높이의 충돌부와 상기 충돌부 상단부에 철망을 구비한 거름망을 구비하여 일정한 크기의 이식재로 분쇄할 수 있는 치아 분쇄기를 개시하고자 한다. 본 발명은, 본체(50)와 분쇄통(20)과, 상기 분쇄통(20) 수용부에 위치하며 상기 모터와 연결되어 회전하는 커터(30)와, 상기 분쇄통(20
