I tried the TMJ specialist dentist. I was not impressed with the dentist / dental appliance approach to TMJ. Instead, I got good results with physical therapy/myofacial release. The PT went deep into my mouth and worked the myofacial release point.

I tend to clench my jaw while I sleep unless I take my gabapentin before bed. I also was directed to a specialist who uses Botox injections into the jaw muscles to get them to relax their tension. She is known to have good success. The PT resolved my TMJ before I could get an appointment with the Botox specialist.
