This thread hasn't been active in many years so you may not hear back from anyone on it. I will share a few things; I have had TMJ for 40 years. Effective treatments have come a long way.
Teeth pain can be a sign of teeth clenching at night. Taking magnesium before bed helps me a lot with that. There are many physical therapists and chiropractors that have effective techniques for treating TMJ. In your area look up TMJ Physical Therapy or TJM Chiropractor.
You may also benefit from a custom appliance to wear at night. I have worn one for many years and I wouldn't go without it. A good dentist can help you with that.
