The temporomandibular joint (TMJ) is the hinge between your lower jaw and skull, one on each side, just in front of your ears. TMJ disorders — sometimes called TMD — are a category of conditions affecting that joint, the muscles around it, or both. Symptoms include jaw clicking or popping, pain when chewing or talking, locking (open or closed), headaches that originate around the temples, ear discomfort without an ear infection, facial soreness on waking, and difficulty opening the mouth wide.
TMJ disorders are common, but they aren't well taught in standard dental training. Most general dentists can identify obvious cases and recommend a night guard, which helps many patients. The harder cases — chronic facial pain, complex muscle patterns, suspected nerve involvement, conditions that overlap with headache disorders or sleep-disordered breathing — require deeper assessment. Dr. Larsen's USC Master of Science in Oral Facial Pain & Oral Medicine is graduate-level training in exactly this domain, and his published research on NMDA receptor antagonists addresses the pharmacology of orofacial pain specifically.
What that translates to for patients: a more thorough assessment than the typical "do you grind?" conversation. We look at jaw mechanics, muscle tenderness, joint sounds, bite, sleep history, headache patterns, stress patterns, and medication history together. Treatment is matched to the actual diagnosis — sometimes a custom night guard from our on-site SprintRay lab is right, sometimes physical therapy referral is right, sometimes medication management makes sense, and sometimes the situation needs ongoing care across multiple modalities. We don't reach for a single tool and call it done.
