You will find plenty of great information about dental care and post OC cancer treatment dental care on this site if you search previous posts. Ther are also many here who will offer their personal experiences and give you great advice.
It sounds like your OMF surgeon is on the ball and as my colleague Jerry states, find a prosthodontist.
Wether you have no teeth or a few teeth left, you still have the same treatment options that non-cancer patients have. The only difference being that their may be certain precautions and or limitations to the way the treatment is performed.
I know that my statement is very vague but I would be happy to answer any questions you may have. Let me know if I can help.
Cheers,
Mike
