Here’s my long story.
I got diagnosed with this when I was 18, the first month of college. It sucked, I hurt a lot. It took about 3 weeks to get my first appliance made in which time I drank a lot of Ensure and smoked a lot of weed.
I took a lot of ibuprofen and ended up with an ulcer from that. Sucked.
I had to have all of my teeth re-aligned, which included a palate stretcher and braces. Also my doctor put some junk on my teeth to build them up in spots so I wouldn’t be able to clamp down fully. Basically fake teeth extensions.
I think the whole orthodontics thing went on for about 2 years until I was set. I got a night appliance to wear and also visited my doctor at least once a year for checkups.
None of this was covered by insurance. Not even awesome union insurance from Ford.
So some years later I started having regular pain again. I had been warned by my doctor that this would happen. My jaw had shifted over and now I was getting pain on the opposite side than I had in the beginning.
We did braces again. He gave me a discount since I was a repeat customer or something. Still not covered by insurance. I got a new nighttime appliance after the braces. He took the fake tooth stuff off my teeth (yeah like 6 years later) and built it in to the appliance.
At one time I had to take a ride on the TENS machine, to completely relax the muscles in my face, so he could do some work. Forget what that was for but it was nice.
I started seeing him as my regular dentist for cleanings so I could have TMJD checkups once a year without an extra trip. The TMJ part of the checkup would be the measuring of my bite and sticking his fingers in my ears while I opened and closed so he could feel my joints.
A year or so ago I was having problems with my back and jaw hurting when I woke up, so I went to get more work done. Then I found out my guy was retiring. NOOOO! He was really awesome. The woman who took over was new but very earnest. She got a totally new kind of night appliance made for me, which works ok but she kept getting it wrong until my original doctor got it settled for her. Hopefully I won’t need as much extensive work from her as I needed from him.
So it’s been 14 years, two sets of braces, palate stretching, three or four night appliances. Still have pain. Still can’t eat popcorn or taffy or even whole apples. I get tired chewing too long or talking too long. Yes, s***g ck is a problem 
The other night I fell asleep for 3 hours without my night appliance. Woke up feeling as if I had fallen out of a tree. Everything ached from the top of my head to the middle of my back, for an entire day.
I’ve gone to the doctor before complaining of an ear infection only to be told there is no infection. The issue is in my jaw. I need to de-stress.
What works for me on bad jaw days is ICE and rest. I lie still with my pillows exactly right and my jaw exactly right and put ice on my jaw and just wait it out. Aleve too, of course.
Relaxing the jaw helps. I like to hold a pen between my front teeth. Helps you not clench. It also helps to put the tip of your tongue on the top of your mouth and hold your teeth apart. It forces you to relax the muscles.
If you need any advice, feel free to PM me. Note that everyone has different degrees of TMJD and every doctor has a different cure.
Two very important things I learned in my research (and I did a lot of research, as I wrote an article about TMJD in college):
- Most dentists cannot help you with TMJD, apart from recommending an orthodontist who can help you. TMJD is not taught in dental school. Do not assume your dentist is going to be an expert on TMJD.
- Do not get surgery unless it has been explained to you as your only option, and you’ve tried everything else. Do not get surgery.
Good luck…I hope your ride is a smooth one.
