gack. My son used to do this...reminded me of a horse cribbing.
I also have vague memories of doing this myself (i can remember off and on from about 1 year)...how wonderful it felt shoving my teeth into something that offered resistance, but that "held" my teeth (aka tooth-marks). Plus it was kind of fun to make a lot, or make them deep, etc. I remember that I preferred wood over cloth/rubber for those reasons, but the memory dies there. I have no idea how my mum handled it. (A problem with a memory that goes back that far, incidentally, is acute embarrassment. Sheesh. What a bizzare series of things to remember...especially when I search and search and search for my car keys).
My two suggestions are this:
1) Redirect whenever you can
2) Broccoli stems, BIG carrots (too big to be put in her mouth and have an end bitten off), potatoes, etc. Frozen, if you like...keeps them from chunking longer. But let's face it...if she's alredy chunking wood...while you have to monitor so she doesn't choke with EITHER at least with the fibrous/hard veggies you don't have to worry about splinters.
