I have been trying to find an answer to that question also.
I have been trying to find a dentist here, a fairly sizable city, for one who can make the device, and it has been futile for the most part.
My sleep doctor recommended a dentist, but I found after a phone call, that he was not taking on any new patients.
Well, I kept trying, so I asked for a recommendation from my own dentist.
Long story short, he didn't know any, but said there was a new orthodontist that had recently begun practise just a few doors from his office.
So, on a lark, I went by the office and asked about the possibility of a mouth device for sleep apnea.
To my surprise, they said they would be glad to help me. So I now have a consultation session set up, and the consultation is cost-free (a rarity)
It will be very similar to the Tap-3 device. http://www.premierdentalcedar.com/conte ... apnea.html
Also, best of all, I asked my sleep doctor for a prescription for the device, and he gave it.
So, as far as I can tell, it is also paid for by Medicare.
I'll keep you informed on how it goes.
