My mom had oral cancer and follow up radiation 6 years ago. She has dementia and it has been hard to make sure she looks after her teeth properly, and that has been exacerbated by severe dry mouth post radiation during this period. Now she needs a few teeth removed including 2 molars on the radiated side. We had multiple oral surgeons and dentists concur on the need for this. One is saying she might need hyperbaric oxygen treatment to heal, which, when I investigated the treatment, looks like it might be quite tough for my mom – both the daily nature and the confined sitting time. Any views or recommendations on any of this to help her through it or what to expect? Thank you!
