Chinchilla does not chew much

I have had my chinchilla for a little less than a year. I got her when she was 3 months old. She barely chews on any of her toys or wood. She will chew on very thin twigs (only certain kinds). I have tried different types of wood, sea grass, banana leaves, vines, finger trap shredders (sometimes will chew on these), coconut shell, and pumice stone. She has shelves with different kinds of wood and different kinds of toys. She will chew on something new the day she gets it then barely touches...
