He is very patient in explaining the issues and answers all questions in layman’s terms. He tried a few options to alleviate my pain and ultimately it was determined that a pharmaceutical strategy would be most effective. I’m extremely pleased with the results and can now chew without pain. I highly recommend Dr. Grin’s services. His staff is also very friendly and responsive. --- ## Dean Bender ## TMJ & Chronic Headaches 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. --- ## Robert T. ## Sleep Apnea / CPAP Alternative 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. --- ## Sarah L. ## EDS & TMJ Disorder --- ![Book appointment form for South Bay TMJ patients requesting care](https://southbaytmj.com/wp-content/uploads/2026/05/outside-building-southbay-scaled-1.jpg) [Map: Dr. Paul Grin, DDS, MPH, MS & Dr. Eric J.
