When you see them again, make sure to discuss all options. For example, rather than extracting, the tooth can get a root canal and can also be "ground down", forgot the official name, but basically bring the tooth down to the gum line but leave the root in place. If this works then you can avoid the HBOT treatments.

I know abut HBOT but not researched it much at all since thus far that bridge is not on the horizon, knock on wood. So far my teeth are holding up. I have had some dental work done post treatment but it was not associated with the rads.
