I 'd give extra baths with a little athletes foot powder in it to makes sure it's not a fungus or even something sticky she has gotten into.
And then give her new/extra chews, and keep switching them out every night.I have even gone as far as move shelves around now and then or even the spot they sleep.
I find adding new pine really helps keep them entertained, they have a real problem with new and straight edges.

I'm steady flipping shelves and turning over huts so I get every edge chewed before I replace. Some of my 6" deep shelves only have an inch left holding them up.
