Full face mask but dry mouth? - ttsoldier - 01-21-2025

I was using a p10 with mouth tape to stop my mouth breathing but it started becoming uncomfortable and I still found myself breathing through my mouth even with the tape. I decided to switch to a full face mask and went with the F40 but sometimes I wake up with my mouth a bit dry. I thought dry mouth would only happen without a full face mask when breathing through your mouth. Is there anything to be concerned about here? Is there anything I can do better? I attached screenshots of 3 nights since I started using the mask on Jan 13th.

I found out that breathing through the mouth 'full stop' causes dry mouth. It's happened with my F40. I also found that even some recommend the use of a chin strap/soft cervical collar (not tape) with a full face mask. With the chin strap or soft cervical collar you can still open your mouth if you really need to. It worked for me. But I switched to a P10 as I'm growing a beard. And the F40 does not get along with beards.

I'm a mouth breather. No way can I breathe thru my nose at night while sleeping. I get dry mouth and I just deal with it. I don't know of any tips or tricks to avoid it.

Ya I tried the chin strap too and no luck with that. Guess I’ll stick with the f40 - beard isn’t in my genetics lol

What was it about the chin strap that didn’t work?  I had some issues with the type of chin straps that put far too much pressure on my chin/jaw to keep it closed. 

I switched to the knightsbridge and it works a treat. Even though it can be a bit of a faff to put on correctly.

I just felt like no matter how tight it was , I could still open my mouth and breathe.

Lots of people use xylimelts for dry mouth. They work well. Here's a link in case you are interested:
