Dear Vicky,
If you remember, I joined this forum when I was suffering from severe post nasal drip that did not respond to all sorts of sprays and also suffered severe dry tongue and mouth. I was using a nose mask Resmed Mirage Activa. I tried our nasal irrigation and saline sprays etc as learnt from this thread. I also tried using the Biotene Dry Mouth toothpaste.
None of these really worked and I was getting nose and throat infections repeatedly.
On 13th December my sleep technician said the problem was caused by air leaking through my mouth an recommended a Resmed Mirage Quattro Full Face mask.
While this mask leaks like a sieve I have realsised that with a full face mask and a humidifier my dry mouth and tongue disappeared altogether and I have not had any antibiotics the last four months, no nasal sprays, no nasal irrigation.
The full face mask and the humidifier seems to have solved my problem finally. So if members who are suffering dry mouth and tongue are using nose masks, this might be the solution they are looking for for eliminating dry tongue and mouth
