Perhaps find a blanket that she chewed on in the past (and obviously likes) and cut it down to a smaller size and put this near her when she's going to bed or for naps. I'm thinking that perhaps she'll chew on this instead. (I'm not sure of this, just thinking that it could be something that you may want to try).
Topher has done this to one decorative pillow on my bed. It's velvet, so perhaps he loved the softness, I don't know, but he has all of the corners chewed and sucked on. He still prefers that to anything, so it's officially his pillow now.
