Buy a few tough plastic teething rings (make sure at least one of them vibrates) and everytime you see her starting to bite into somthing that she shouldn't, pick her up and out of the way of whatever she's planning on sinking her teeth into, hand her one of the teeth rings and tell her something like, "this is what we can chew." This could all be part of her teething process or her need to explore her world with her mouth -- all perfectly normal.
If you find that, several months down the line, her interest in chewing things and mouthing things doesn't seem to be fading away, I would suggest talking to your pediatrician about this and ask him to give you a referral to have your daughter evaluated by an Occupational Therapist. Some children have what's knowns as Sensory Processing Disorder which causes them to seek out sensory input with their mouth. If this is the case, the the OT can help regulate your daughter's senses so that she is not constantly putting inedible objects in her mouth and chewing on them.
Hope this helps. Have a good day.
