BD,
Best wishes for an uneventful surgery for the teeth and a complete, complication free recovery. The hyperbaric medicine is remarkable, I have watched it while using the Wound Center here for my fistulas and surgical wounds. I got to do the engineering documentation on the relocation of one of the Navy's chambers in the late 80's when my company built a new Aviation Physiology building at N.A.S. Pensacola. what an incredible piece of equipment. Best of Luck with both the surgery and the retirement.
