Hope you're reading this reply after getting some sleep
I've also had a tooth out recently, one of the top front ones, so I know how you feel. Fortunately, I didn't have too much trouble with bleeding, though it was pretty sore for a few days. I do now find that my mask pushes against the gap and so it gets a bit sore sometimes, but I've only got to wait a couple of months before the dentist can build a bionic one to replace it
Have you got a comfortable armchair? When I was struggling to get used to sleeping with xPAP and the attached stuff, I got to the stage where I didn't like the idea of lying down with the mask on - it was in the days before I had a
heated humidifier so I got lots of nasal congestion.
So one afternoon, in desperation, I used pillows, a couple of quilts and a footstool to get comfortable in a sitting position in my favourite armchair, put on the mask and managed to get about 90 minutes sleep. Doesn't sound a lot, but that was probably the longest uninterrupted period of sleep I'd had for months
The trick is getting the pillows organised so your neck is reasonably upright and secure, so that your head doesn't flop forward.
Good luck
