The answer to that question that I was always given was "I don't know", reason that everybody's different.
I am new to this forum, but am 3 years out of treatment. I feel it took me over two years to recover to where I could be, which, of course, is not where I used to be.
But I was older when I was diagnosed and now I'm even older, so false teeth and pain every day is not really a surprise but somewhat expected and someway of a surprise.
Paul is right: was the hardest thing I've ever done.
Good luck and get lots of support.
