I already had TMJ dysfunction and had worn a lower night guard for millennia. My upper four front teeth were tender and I was getting a gap between the front two teeth. The entire top teeth were spacing more loosely. I could tell this visually as well as by the difference when flossing. My dentist made my nightguard for TMJD on the upper teeth and a lighter nightguard for the bottom teeth.
After getting the new setup I still had tenderness in the upper teeth. I moved my mask up a tad higher and that completed the solution.
My interpretation of the events is that the mask was riding low over my teeth and my tongue was, unconsciously trying to push it off.
After wearing the new nightguards for a couple of weeks, the spacing issue corrected itself.
Not a lot of people have this problem but a few do. More than just you and me by far. It probably has a lot to do with different facial characteristics.
After my experience, I suggest playing with your mask fit. A 1/4 inch higher might be all you need. If you have a different mask, you could also try that. Something that doesn't rest on the upper jaw /teeth. From there you might try a nightguard. Braces would be my last choice unless you have other alignment issues you want to correct.
Thanks for this info, Cpapian. I think I have a short upper lip. There’s really only one spot for my nasal pillows to sit. I used a nasal mask when I first started out with CPAP. Maybe I’ll give that a try again and ask my dentist about a nightguard.
