I just caught my bunny red-pawed munching on a candle, not much but I saw teeth marks. Should I be worried?

It's a really old candle, but like I said, not much of it was eaten. Just some chewed off little slices, just about as much as her teeth would pull, ya know? She's my angel and I just want to make sure she isn't gonna start throwing it up or something cause I know that's bad for them.
