Dental occlusion refers to the way the teeth fit together or the “bite”. Historically, the dental profession has viewed malocclusion (abnormal bite) as a primary causative factor in TMD. Recent valid research studies have shown that malocclusion is usually not the cause of TMD except in a limited number of cases. There may be situations when the way the teeth fit together may play a contributing role in the initiation or progression of those limited situations. Each case needs to be individually evaluated by the orofacial pain doctor to determine a possible relationship.
