Tpn and teeth

Anyone had a nicu baby? My baby was in the nicu for two months and on TPN for 45 days. I read a post on a Facebook group a long while back and a vast majority said tpn affected their babies baby teeth. Weak, brittle, and yellow in colour.

But I’m wondering how long it took anyone’s littles to get their first teeth if maybe it took longer because of tpn. My baby will be 9 months on the 1st and doesn’t have any teeth and has not showed any signs of teething since she was born besides red cheeks once and a while.

Thank you.
