There are also central nervous system pathologies, such as Parkinson’s disease and schizophrenia, as well as dental occlusion factors, genetics, local irritation, such as gum and periodontal inflammation, and teeth grinding may also be related to blood pressure and blood sugar that are not in the normal range, as well as sleep and breathing disorders, smoking and alcohol abuse, and many other factors. At present, there is no particularly effective treatment for teeth grinding. You can choose psychological and behavioral treatment, that is, to pay attention to relieve the stress of the heart, pay attention to relaxation, reduce mental tension. You can consider methods such as physical therapy and biofeedback to relax the local muscles. Bite plates can be considered to reduce the trauma to the surrounding tissues caused by teeth grinding. If there is a clear local cause, such as periodontal inflammation, the cause should be actively removed.
