South Bay TMJ, Sleep, Headache & Orofacial Pain Institute is a specialized medical practice in Torrance, CA, focused on diagnosing and treating pain conditions of the jaw, face, head, and neck. Our board-certified orofacial pain specialists, Dr. Paul Grin and Dr. Eric Grin, are both Diplomates of the American Board of Orofacial Pain and clinical faculty at UCLA. With over 32 years of clinical experience, our practice offers advanced, conservative care for TMJ disorders, headaches, facial pain, nerve pain, and sleep-disordered breathing.
Orofacial pain is a specialized field with fewer than 500 board-certified practitioners worldwide. Most patients with chronic jaw pain or facial pain see multiple doctors before finding a specialist with the right training. Our practice exists to shorten that journey.
Board-certified orofacial pain specialists are rare worldwide, and both of ours are among them. The American Academy of Orofacial Pain reports that the average TMJ patient sees 5.3 doctors over 4.2 years before finding the right specialist.
Orofacial pain is one of the rarest medical specialties. Most patients see multiple doctors before finding one with the right training. Our doctors completed advanced postgraduate training specifically focused on the conditions affecting the jaw, face, head, and neck.
Both Dr. Paul Grin and Dr. Eric Grin hold the highest credential in the field, earned through rigorous examination and demonstrated clinical competence.
Six commitments that define how we care for every patient who walks through our doors.
We never double-book. When you come to our office, the time you schedule is yours alone. Your doctor gives you full, undivided attention. This is especially important for complex pain conditions that require thorough evaluation.
Your first visit lasts 45 to 60 minutes. We take the time to review your complete medical history, listen to your symptoms in detail, and perform a comprehensive exam before recommending any treatment.

“I needed to visit Dr. Grin for jaw pain, and was referred from my Dentist. Dr Grin has a calm and well run office. I was intaked easily without waiting. His initial exam (H&P) was very detailed and covered my entire history, complaint, prior treatments, concerns, etc. Amazingly thorough. Also had a cat scan on premises!
He developed a straight-forward plan of care which was easy for me to follow. My pain resolved and I was discharged after just one return visit, but welcomed to return if I ever needed his attention again.
Top tier, great bedside manner, well run office and staff. Most impressive and effective for a specialty provider.❤️4″
“I couldn’t tolerate my CPAP machine despite trying for months. Dr. Grin fitted me with a custom oral appliance and a follow-up sleep study confirmed it works. I sleep through the night and feel like myself again.”
“As someone with EDS, finding a TMJ specialist who actually understood my condition was life-changing. Dr. Grin used a conservative approach that protected my jaw and the prolotherapy has made a real difference.”
