In the health system that I'm a part of here in the states, the medical professionals offer CPAP first if the AHI is <15 and greater than five. If the patients balks, they then suggest a dental appliance. However, the health insurance will not cover the dental appliance, nor will they cover the follow up sleep study to see how well the appliance is treating the apnea.
My TMJ dental appliances and treatment cost around $5,000.00, but the expense keeps on above and beyond that due to the necessary maintenance biannually. That was all out-of-pocket for me.
I didn't get these appliances to treat my apnea, but a subsequent sleep test at home showed that my AHI had been reduced by 12, down to twenty-four. My health insurance covered that second sleep study because they wanted to get a base-level reading with my new appliance to see what AHI level remained and whether my CPAP treatment would reduce those remaining apneas down below an AHI of 5. It was an eureka moment. My AHIs today are usually in the 0.5 range.
I was truly out of options. I needed the CPAP, but couldn't do that because its' pressures produced TMJ in me and the pain from that was overwhelming. I had to have the TMJ Disorder treatment in order to tolerate the CPAP. The problem was solved my first night of dental appliance therapy with CPAP. No pain. I knew I had made the right choice for me, but it was a guessing game up until that point.
The trouble with the standard dental appliances issued for sleep apnea is from the constant moving of the lower jaw forward each night and then trying to coax it back into it's original position during the daytime and then repeating this with the each following night of therapy. This puts incredible strain on the TMJs and the whole musculature supporting the jaw. The muscles go into spasm and the pain from that is enough to keep you from eating and even from talking. So you go along hungry and isolated. But you lose weight...in some cases a lot of weight. Then, your brain becomes confused and begs an answer to the question; "Where does my jaw belong?". Your jaw seems to be floating in an empty cavern. Our brains crave a norm of some kind. So, the bite gets thrown off. Teeth get cracked and broken (our bites are powerful) with some teeth needing extraction. And the patient is left wondering; "How did this ever happen?" "Could my dental appliance treatment for sleep apnea be causing this?" And no one seems to know.
Perhaps you're an anomaly. No... you're not. You're just one cog among many, caught up in the machinery of the industry. Your solution in the end is to just take the thing out of your mouth. But the pain doesn't go away while your jaw is floating around in never, never land. Your bite never seems to find "home base" and you're left at ground level once again, with sleep apnea and no treatment and dental bills to boot. This happens more often than anyone is yet really aware of. If you have Medicare and have "failed" (non-compliant) the first go at CPAP therapy, Medicare no longer wants to invest at all in your treatment and you are left on your own. We have to be strong and advocate for ourselves in this sleep apnea business.
So, "B" follows "A" and "C" comes after that. When the dental profession finally catches on to this, there will surely be a revolution - and for the better. But, I'm not going to risk my health and well-being in the meanwhile, as the figuring-out process is going on.
