That said, you’ll want to go to a dentist who specializes in sleep apnea and is able to test / fit the oral appliance properly. (Source: father is dentist who specializes in TMJ pain and sleep apnea).
Seems like the 3d scanning my kids had for their braces, plus 3D printing could make it less expensive, at least for a prototype device to just try.
I should try that "tape over the mouth" thing to see if it helps, particularly as I'm super mild apnea, but I'm expecting it won't really work with my beard.
I do tape over the mouth every night. It’s worth a try! I also wear an oral appliance to prevent teeth clenching at night which was a game changer for me in terms of jaw muscle inflammation (due to clenching).
Mouth taping is one thing my dad (dentist) recommends for people who snore. While I don’t snore or have sleep apnea, I do feel like I get a more restful sleep.
