A dental instrument to prevent accidentally swallowing a filler, etc. has a circumferential wall for drop prevention mounted on the periphery of a receiving plate. A grip is attached to the receiving plate or circumferential wall. The dental instrument is inserted in the mouth to catch the prosthetic appliance, filler, etc. coming off during a dental treatment, preventing the prosthetic appliance, filler, etc. from dropping into the trachea or gullet. |
