I'm 66 years old. I had all my remaining teeth extracted about a decade ago. I got dentures a year after all my teeth were extracted. I was diagnosed with Sleep Apnea 17 years ago. I've used nasal pillows and masks that cover the nose and mouth. I've finally admitted all those masks fail to maintain a seal. Now I'm trying to convince my doctor and CPAP nurse that I need a mask that covers the forehead, chin, etc. I'm surprised it's been so difficult.
I don't believe it's safe to wear my dentures when sleeping. At times I woke and realized I was popping the dentures loose when I was sleeping. The dentures banged on the inside of the BiPap mask. It was a really frightening experience. I also noticed that my BiPap mask still gets out of adjustment whenever I wear dentures. The noise of escaping air wakes me up & scares me. Sometimes all that noise becomes part of my dreams.
I'm hoping to finally get a handle on this situation. I hesitate to get a mouthguard. I fear it won't be any better than dentures.
