The most common temporomandibular joint dysfunction (TMD) symptom is orofacial pain. Orofacial pain involves pain at the mouth, face, ear, and the surrounding head and neck areas. 10 the 15% of the US population suffers from some type of orofacial pain, and the most common cause is temporomandibular joint dysfunction. In fact, these TMD symptoms commonly result from muscular trigger points at the face and jaw that are associated with TMD. The orofacial pain component of TMD symptoms are dull, aching, or throbbing. Patients have described the face pain as like a “weight on my face”, “needles, digging in and shooting,” and “painful tightening.” Sometimes the pain will radiate towards the head or neck. Sometimes there is pain isolated to one or more teeth, resulting in a dental evaluation.
