There is no authoritative literature on the most effective method of treating nocturnal teeth grinding. Commonly used treatments include occlusal plate therapy, jaw therapy, and psychotherapy, as follows. 1. Occlusal plate treatment: the occlusal plate is placed between the upper and lower jaw teeth to reduce the abnormal muscle activity and make the temporomandibular joint more stable, in order to reduce the frequency of nocturnal teeth grinding. 2. Jaw treatment: eliminating jaw interference through jaw adjustment, restoration, orthodontic treatment, and occlusal reconstruction in order to alleviate the night grinding caused by it. 3. Psychological treatment: Night grinding is related to depression, anxiety and other negative emotions. Reducing negative emotions through psychological treatment can alleviate the development of night grinding to a certain extent. It is recommended to go to the hospital in time to receive professional treatment as soon as possible.
