I have the same problem!
I had to have a tooth pulled after my AN surgery because it cracked. I guess there's a lot of extra wear and tear when you can only chew on one side. After it was all healed, I'm still able to eat (where there's a will, there's a way!), but I will say some things are a lot of work. I'm in the process of deciding if I want to do an implant to replace the tooth or a bridge, but I'm certainly not starving to death in the meantime!
I have had tons of dental problems I didn't have before the facial paralysis. My dentist doesn't want to be too aggressive in fixing them now because we don't know how much movement I will ultimately wind up with after my nerve graft, but I think the time is coming when things will need to be addressed.
You just don't realize that having one thing "fixed" can lead to so many other things breaking!
Good luck - and go get yourself some ice cream!
