I had treatment for TMJD when I was 18. I got to the point where I couldn’t eat anything but meal replacement shakes because I couldn’t get my mouth open anymore. It was horrible!
But, my dad’s insurance wouldn’t cover any treatment. They considered TMJD treatment to be elective. And this was a really good insurance plan, too!
When I first saw my TMJD doctor, I got a packet of info about different kinds of treatment and information about payments. The doctor had so much experience with treatment being denied coverage that he had a bunch of pre-printed sheets on the matter 
My mom actually found the packet the other day and gave it to me, so I actually have it sitting right here. Treatment cost $3900 and this was 12 years ago.
So, I got adjusted and my pain did go away. It was a miracle. Well, 5 years after my first treatment I had to go back and get adjusted again. My alignment had slipped again! I had been seeing the doctor all along, like every 6 months, so it wasn’t a big deal to talk to him about my options. I ended up getting braces again, tho.
He did give me a discount on the second time since he considered it “continuing treatment.”
Anyway, it may sound like I was disappointed in the whole experience but I’m not. I AM disappointed in the insurance company’s treatment of TMJD. I’ve done a lot of research on it in the past 12 years and I have found that most insurance companies do not cover TMJD treatment at all, no matter what the cause or what the type of treatment. I did an extensive article on it in journalism school and interviewed several patients across the country and they all said the same thing.
I’m not disappointed in my treatment, tho. Everything I’ve read said that adjustment isn’t a magic bullet. Neither is surgery. I was bummed but not surprised when I had to go for a second round of treatment in my 20s. I wouldn’t be surprised if I had to go again sometime to get re-re-adjusted.
Not A Platypus, I do hope you do get treatment. The cost will be what it is. In my case, I got to pay off my doctor in monthly installments with no interest. Hopefully yours will be as accommodating. The most important thing is to start getting treatment because living with the pain is just unbearable. It won’t get better, it will get worse. And it will drag everything else about you along with it.
I’ll be thinking about you. Hope you find some relief soon!
