The bones that ring here are actually the temporomandibular joint, which is located in the depression in front of the ear screen and can be felt in front of the ear screen. The bone will ring when the mouth is opened wide and may be accompanied by pressure pain in front of the joint. If there is a misalignment of the temporomandibular joint disc and joint surface, or if there is acute congestion and inflammation, there will be symptoms of popping of the mouth, pain in the joint area, and a series of symptoms such as crushing sounds and restricted mouth opening. Patients whose mouths open wide and bones ring must avoid opening their mouths wide when talking, eating, or yawning to avoid re-damaging the joint. You can also use hot compresses, or local physical therapy of the joint to promote the absorption of inflammation in the joint, or go to the hospital to use jaw adjustment or wear occlusal pads to relieve the inflammation in the joint area.
