The obvious ringing of the joints when biting indicates that the temporomandibular joints are dysfunctional, in which case appropriate treatment must be done. First of all, the temporomandibular joint dysfunction is usually accompanied by limited mouth opening and pain when biting, etc. At this time, you should strictly control the opening of the mouth, and try to talk less and open the mouth less. Secondly, corresponding physical therapy such as microwave physiotherapy should be done for TMJ, and oral medication can be taken to activate blood circulation and eliminate blood stasis, so as to alleviate the symptoms of the joints. In daily life, we must eat soft food to prevent eating hard things for further damage to the joints, through a period of time after strict closed mouth treatment, the general bite joint rattle will gradually disappear.
