I rinse with Biotene a few times a day or I have a problem too. I have been out of TX for over 2 years too and the biotene does help keep the moisture up. I wonder if dryness caused the bone to be exposed on my lower right gum? Never thought about that until now. I guess everything is possible in our world.

Since posting this. UPMC, Pittsburgh, Oct 2011 until Jan. I averaged about 2 to 3 surgeries a week there. w Can't have jaw made as bone is deteroriating steaily that is left in jaw. Mersa is to blame. Feeding tube . Had trach for 4mos. Got it out April.
