Sleep Apnea is literally when you (mildly) choke-yourself while sleeping and can't breath. If the mouth-guard falls off easily and causes a choking hazard, then the mouthguard is worse than the disease.
I know there's online discussion about chin-straps moving the jaw forward. That's closer to something I think I'd be willing to experiment with. I don't see much potential choking hazards or other problems.
At $15 you should try that before forking $1000 (on something that you can get for $150 outside the USA, btw).
Also mouth guard don't cause choking hazard.
I had a dentist prescribed/adjusted MAD which cost $400. I hated that thing. I purchased a $10 nightguard at Target, less intrusive, smaller, more flimsy and flexible version, at target. It works great and last 6 months.
Its not like I'm on Amazon checking prices while the doctor is talking to me. And its not like doctors tell you how much something costs until after they give it to you. These things are mostly "do as the doctor says" and then look at the bill later.
In any case, a lot of the mouthguards are just bruxism / teeth grinding protection. I'll let you know that "pushing the jaw forward" is how my device works.
Other people have linked cheaper stuff from various places online which seem like they push the jaw forward. But most dental-guards I see at Target / CVS / etc. etc. are just bruxism protection, probably not designed for sleep apnea.

Now that I know what I have and can do comparison shopping, the thing that has gotten good reviews seems to be "ZQuiet". Seems to be well reviewed by 3rd party websites, and not super-expensive. $80 or so. https://zquiet.com/
Another person upthread claims they got good results from something from Amazon, but I couldn't find much information about that company or website.
