No problem Dizzey! From what I understand not all OC patients have teeth issues due to radiation, and I believe it's something that happens down the road if you do. Probably why it wasn't mentioned. But studies are showing that HBO has great benefits for OC patients above and beyond jaw deterioration prevention. I learned that radiation to the oral cavity is so damaging that it takes a lot of dives to repair some of the damage. My insurance covered the maximum of 60, which is what I did. I hope your NHS will help cover the treatment if you decide to do it. I would like to see HBO therapy promoted by all Radiologists for follow-up treatment after radiation. I think it should be protocol after experiencing my results. Good luck to you! I am not on this site all that often but I've read some of your posts and it sounds like you have an excellent attitude and you are taking this massive life changing challenge by the horns. It's remarkable and inspiring.
