Current research shows that the most likely cause of bruxism is malocclusion (alignment) between maxillary and mandibular teeth. When you close your mouth in contact with your teeth and stress your facial muscles and your chin, you inadvertently place your jaw in places where your muscles feel less stressful. Therefore, the teeth move and rub against each other.
Emphasis on anxiety or stress is also considered to be one of the causes of bruxism in one's life. People with a stressful lifestyle are more likely to grind their teeth at night, sometimes even during the day. One of the recommendations is to reduce caffeine intake to reduce anxiety.
Others believe that when someone has sleep awakening, bruxism may occur. Therefore, bruxism is observed during sleep involving abnormal dreams of sports, emotions, and unconsciousness. Recent studies have also concluded that bruxism is associated with snoring and sleep apnea.
Drug Researshers believes that taking a variety of drugs or recreational drugs may lead to the development of bruxism. These substances include some antidepressants, some antipsychotics, some amphetamines and cocaine and alcohol. People also believe that dental occlusion may be associated with Huntington's disease, Parkinson's disease, Down's syndrome, autism, epilepsy and some other diseases.
