The bone of the jaw contour usually refers to the jawbone. Pain in the jawbone may occur due to factors such as inflammatory infection, local trauma, local tumor, etc. If the pain is obvious or has other accompanying symptoms, it is recommended to seek medical attention promptly.1. Inflammatory infection factor: Osteomyelitis of the jawbone can cause the jawbone to feel pain. In addition, because there is sometimes a bias in people’s perception of pain, feeling pain in the bone is not necessarily a lesion in the jawbone. Infections in the soft tissues around the jawbone, such as lymphadenitis, and odontogenic infections such as periapical infection or pulpitis leading to facial interstitial infection, may cause patients to feel pain in the bone; 2. Local trauma: collision or extrusion of the head and face, resulting in swelling of local soft tissues or bone and pain, and in serious cases, it may even affect the bite of the joint, which can be determined by taking a film to determine whether dislocation or fracture occurs; 3, temporomandibular joint disorder: unilateral chewing, poor dental bite relationship, chewing hard objects, cold and other factors can cause temporomandibular joint disorder, which may cause pain in the bones; 4, local tumor: if the pain attack lasts for a long time and is difficult to relieve, consider whether it is a mandibular cyst or tumor , magnetic resonance or local CT examination is needed to make a clear diagnosis. No matter which kind of pain is needed to go to the hospital to improve the relevant examination, clear the cause of treatment, do not blindly self-medication to relieve, to avoid delaying the disease, causing more damage to health.
