Perfume works well for mine. I can’t tell you for sure that it wouldn’t damage all wood, but it hasn’t mine. I don’t want a huge smell of perfume, so I spray it on a paper towel (you don’t have to soak it, just a light spray) and then I wipe it on the areas that I don’t want chewed.
Another member had success with pure lemon oil, while others say rubbing lemon rind on worked.
What exactly is she chewing on, a dresser, a table leg??? I know with Jack he likes to chew on the end of a particular door when it’ s open. I use one "Fiddle Sticks" Flexible wood thing around the edge of it and he chews on that instead. Here are some links to what it looks like.

I prefer the more natural wood look so it doesn’t stand out so much.
Note: these are pictures I found on ebay. I don’t know those sellers and can’t vouch for them, but at least it offers pictures. I was having hard time finding the "natural" ones online. I just got mine at a local pet supply.
