There's a thread here that you might find helpful Managing Bar Chewers
Bar chewing is less common in dwarfs, it mostly seems to be a bit of a syrian thing so hopefully you'll be able to break the habit!
You could try giving her something like antos dog chews & some bonio puppy dog biscuits to chew on, make sure she has plenty of toys to occupy her & a big enough wheel to run in.
What cage do you have? If her cage is a bit small that might contribute to the problem.
