I had this trouble with my chocolate syrian girl, Kashi (rip). She was in the barney cage (from zooplus) 100cm x 54cm. I gave her loads of cardboard woven in amd out of the bars which I replaced very regularly.

I also got her the lovely silent runner wheel. She did stop chewing and remained lively and inquisitive til the end.

Best of luck finding ways to entertain her.
