Some have been able to train themselves to keep their tongue in the right position at the front of the mouth so that even when the muscles are fully relaxed, the tongue position creates a slight "suction" effect that keeps the lips shut.
Try it. Place the tongue against the area at the front of the roof of the mouth just above the teeth. Consciously suck the saliva and air out of that area. Now allow the jaw to drop slightly. Can you feel the suction pull at the lips and the sides of the mouth? If a person has slept with his mouth open for years, this doesn't come naturally at first--it has to be relearned. But some have been able to do so with a little conscious effort.
Other people need a chin strap. I had to use a dental device for a while to keep my mouth shut. Still others (controversially) tape their mouth shut. Others use a mask that covers nose AND mouth so they don't have to worry about the mouth coming open.
Finding a way to stay off one's back while asleep can make a big difference too. It is harder for most people to keep the mouth closed during sleep when on their back.
I have the same problem as Cheryl: my cheeks balloon and eventually air is forced through my lips. I've tried the "controversial" taping of the mouth and the chin strap. They both work but are awkward. My solution was to switch from the nasal mask (my favorite) to a full face mask that actually permits my mouth to open. This works great - the CPAP forces air through both my nose and my mouth and I experience really deep sleep. You need a mask that fits under-the-chin, not under-the-lip. I suspect that this works well for me because I have a deviated septum which limits the airflow through my nose. Stanford has recommended surgery. For now, mouth-open-with-full-face is a great fix.
Not trying to upset, but, if you wear a full face mask, you shouldn't be worried about your mouth at all. That's why I went to a full face mask, I had a problem with my mouth being open all the time, so the CPAP was less effective.
Joe, what type of mask do you use? I have 2 that I seem to tolerate okay, except that they hurt my bridge of nose and dig into my cheek bone on one side. NO matter how I adjust it, this happens and I wake with a headache/marks on my face and pain. Now I wore a Liberty mask last nite, but that somehow keeps my mouth open the whole time and dries it so bad. I guess that is the price to pay. For me, the doctors cannot seem to see why I have this sleep apnea. I have no obvious anything in my situation in my mouth that could cause this. I had sinus surgery, coincidentally, the same week I got my results back from the sleep lab. The sinus surgery is still healing and has been about 4 months now, so am hoping it helped with the apnea. But for me, this has been a nightmare trying to find a mask. The fullface used to make me claustrophobic and it weighed down on my face, thus I tried the nasal pillows, but had the mouth fill problem...-it may be getting better, as I am better able to tolerate the fullface, but am still having the marks/pain and dry mouth. I do use the humidifier on my cpap and am hoping that my next sleep lab next week will show this apnea stuff has improved and maybe I can get an autopap or at least look into it. I think I breathe too slow and that is why the mouth fills with air. I'm very new to all this yet and am still trying to figure it all out. Seems like SOOOOO many people have the same problems, thanks for your input
