Mandibular joint disorders are somewhat self-limiting, and about 10% of patients can slowly heal on their own; the time of self-healing needs to be determined by the patient’s own condition. However, most patients are recommended to go to the temporomandibular joint department of a regular hospital for standardized treatment in order to effectively relieve the symptoms. There are many causes of jaw joint disorders, such as emotional anxiety, mental tension, lateral chewing, strain from biting hard things and cold. If the condition is mild, timely change of bad habits and removal of psychosomatic factors may improve the symptoms and achieve self-healing in 3-5 days. However, if the symptoms are more severe or caused by factors such as misaligned teeth or wisdom teeth interference, it is usually not possible to achieve self-healing, so timely consultation is needed to exclude organic diseases and give the appropriate treatment plan to avoid delaying treatment. In daily life, patients should pay attention to rest, maintain a good state of mind, eliminate mental and psychological factors, and give appropriate joint massage and hot compresses. At the same time, change the habit of lateralization, avoid wide open mouth, do not bite hard things and chew gum, etc.
