Orofacial Pain Group

Orofacial pain specialists assess, diagnose and treat patients with complex, chronic pain in the mouth, jaws and face. They treat orofacial pain that may result from an accident or trauma, or as a symptom of a disorder or disease, such as migraines or jaw pain.


Orofacial pain specialists utilize patient history, pathology (lab work and imaging), and other assessments to assist the dental health care team with a diagnosis and treatment plan.


At the Dental Faculty Practice, orofacial pain specialists provide services in the management of chronic orofacial pain and other sensory disorders.


Services include:


  • Treatment of pain from temporomandibular (jaw) disorders (TMD)
  • Treatment of chronic post-traumatic pain
  • Treatment of pain from maxillofacial nerve injuries
