Disclosed is an apparatus for removing a dental prosthesis using a solenoid, which can prevent damage to neighboring teeth or wound on gums in removing a dental prosthesis encapsulating teeth, and easily remove a dental prosthesis inside the mouth regardless of position of teeth which the dental prosthesis encapsulates. According to an embodiment of the present invention, the apparatus for removing a dental prosthesis using a solenoid is applied to an apparatus for removing a dental prosthesis in order to remove the dental prothesis encapsulating teeth. The apparatus for removing a dental prosthesis using a solenoid comprises: a dental prothesis-removing tip having a hook portion formed on one end； a case composed of a lower case in which the other end of the dental prothesis-removing tip is connected to the bottom surface thereof to be able to be detached, and an upper case which is tightly fixed to the upper part of the lower case； a solenoid embedded in the case and including a plunger which moves along a straight line as much as any strokes when electrical signals are applied to an electromagnetic coil from the outside； and a hitting body formed on the end of the plunger to hit the upper case when the solenoid is run on. When the hook portion is hooked to the lower part of the dental prosthesis, and electrical signals continue to be applied and blocked repeatedly to the electromagnetic coil of the solenoid, the hitting body of the plunger moving along a straight line repeatedly hits the upper case such that repulsive force is generated to separate the dental prosthesis from the teeth.COPYRIGHT KIPO 2018게시된 내용은 치아에 덧씌워진 보철물을 분리시킬 경우 주변 치아의 훼손 또는 잇몸 부위에 상처 입는 것을 방지할 수 있고, 보철물이 씌워진 치아 위치에 상관없이 구강 안쪽의 보철물도 용이하게 제거할 수 있는 솔레노이드를 이용한 치아 보철물 제거장치에 관한 것으로,본 명세서의 일 실시예에 의한 솔레노이드를 이용한 치아 보철물 제거장치는치아에 덧씌워진 보철물을 제거하기 위한 치아 보철물 제거장치에 적용되고,갈고리부가 일단에 형성되는 보철물 제거팁；상기 보철물 제거팁의 타단이 바닥면에 착탈가능하게 연결되는 하부 케이스와, 상기 하부 케이스 상단에 밀착고정되는 상부 케이스로 이루어지는 케이스；상기 케이스에 내설되고, 외부로부터 전자코일에
