I have been using CPAP for 15 years plus, I no longer have any issues and use it without a second thought every night. But now my 76yo father has started on his CPAP journey and is really struggling.
His main issue is mouth leak, likely caused by his false teeth. Somethimes he leaves the dentures in sometimes just the upper plate and sometimes he leaves them out enturely. In any case he gets terrible mouth leak.
At the moment he is using a Fisher and Pykel nasal mask, though he also has a Resmed full face mask that he has tried.
The fundamental probem seems to be that his have isn't firm enough without teeth to support the mask seal. Even a chin strap is useless.
Any ideas that have worked for people with dentures? Preferably not wearing the dentures at all at night.
I think the problem he has with a full face mask is that the crease between the chin and the lower teeth doesn't exist so the mask rides up and leaks above the nose.
