Does breastfeeding cause cavities?

My sister's baby developed some cavities, and she mentioned she was exclusively breastfeeding. Could there be a connection? Does breastfeeding cause cavities in babies' teeth?

Breastfeeding itself doesn't cause cavities, but nighttime feeds can if milk sits on the baby's tiny teeth! Just wipe their gums and teeth with a damp soft cloth after feeds. It works wonders and keeps those little smiles bright.

I completely understand why you are worried, I panicked when my teeth started feeling sensitive while nursing. It turns out I was ignoring my own dental hygiene and calcium intake due to baby exhaustion. Please don't worry, just take care of your nutrition and visit a dentist once.

If you are talking about mother's teeth, breastfeeding can deplete calcium if your diet is poor, which makes teeth weak. For babies, sleeping with milk in the mouth is the main culprit. Make sure you brush twice daily and clean your baby's mouth too, no shortcut here.

My grandmother used to say breastfeeding causes mother's teeth to fall, but our family dentist cleared this myth. It only happens if the mother does not take enough calcium supplements during lactation. Please consult your dentist for a proper calcium plan.

According to health trackers and dental studies, breast milk alone doesn't cause decay, but when mixed with other sweet foods or juice, it can speed up cavity formation. Keep track of when your baby eats and try to clean their mouth before bed.
