TMJ popping is caused by anterior displacement of the articular disc. At this time, joint protection actions should be carried out, including not opening the mouth wide, not biting hard objects, and paying attention to local physical therapy and hot compresses, so that the condition can be controlled, and sometimes it will heal itself. If no intervention is given and no attention is paid to joint protection, the condition will develop into irreducible anterior displacement of the disc. If it is irreducible anterior displacement of the disc, the disc will be squeezed and with long-term development, the disc will be prone to rupture or even perforation. Painful perforation of the disc will occur. If not treated in a timely manner, it can progress to the level of osteoarthritis and osteoarthrosis, which is more complicated to treat. If the disc is perforated or ruptured, surgery is required to remove the disc and fill it with tissue from other parts of the body, as well as to make a prosthetic joint. If the TMJ is rattling, it is important to go to a regular hospital to avoid delaying the treatment of the condition.
