Baby biting while nursing

My little girl has started to bite me with her two bottom teeth while nursing! A few mom friends told me to push her head into my boob to “smother” her for a second or two while nursing to get her to release ... the little chomper just bites harder! Any tips or tricks on getting them to release and to also nip this habit in the butt? My boobs are in rough shape right now. I don’t want to stop nursing as I love the bonding but not sure how much more I can take!!
