Whether or not TMJ disorders can heal on their own, and how long it takes to heal, needs to be determined by the progression of the condition. Temporomandibular joint disorder is a group of diseases with pain or popping in the joint area, pain in the masticatory muscles, pain in the joint area, and restricted mouth opening as the main symptoms. The cause is not clear, but it is related to trauma, mental stress, poor occlusion, bad habits, immune factors, and specificity of joint anatomy. In the early stage of the disease, it can only be manifested as pain in the masticatory muscles, pain in the opening of the mouth or restricted opening of the mouth, affecting normal life and diet, at this time, such as physical therapy or hot compresses, and supplemented by rehabilitation, can generally achieve self-healing, which takes 2 weeks to several months. However, if the condition worsens, with frequent joint popping and organic lesions of the joint structure, irreversible damage to the joint may occur and surgery may be required. In the case of TMJ pain or discomfort of varying degrees, it is recommended to visit a professional dental hospital to avoid irreversible joint damage due to delayed treatment.
