If there is a noticeable ringing sound in the joint when biting, it means that the temporomandibular joint dysfunction has occurred, and in this case, appropriate treatment must be done. First of all, TMJ dysfunction is usually accompanied by restricted mouth opening and pain when biting, so you should strictly control the large mouth opening and try to talk less and open your mouth less. Secondly, the TMJ should be treated with physical therapy such as microwave physiotherapy and oral medication to relieve the symptoms of the joint. In daily life, we must eat soft food to prevent further damage to the joint by eating hard things. After a period of strict closed-mouth treatment, generally the occlusal joint ringing will gradually disappear.
