I am one year+ "out of treatment" and am experiencing the same issues described here. I am being treated at a VA hospital and have been told that all of my remaining teeth must be extracted and I will be fitted with dentures.
At first the HBO treatment was discussed (and the dismissed by the oral surgeon) I have a final consult scheduled in early June and final determination will be made. The current "plan" is to remove 22 teeth in one sitting. Not looking forward to that I can tell you. Don't know what to expect and am a bit freaked.
Good luck to you & husband I will be following your situation and know that you both are in my thoughts.
My best to you & yours,
