Does breast milk cause cavities?

My baby is 6 months old and exclusively breastfed. My sister-in-law mentioned that breast milk can cause cavities if babies sleep with the bottle. Is it true that breast milk can cause cavities, even without a bottle?

Breast milk alone does not cause cavities, but if it pools in the mouth at night along with other food residues, bacteria can grow. The practical solution is to wipe your baby's gums or teeth with a clean, damp cloth after the last feed. This keeps their mouth clean without stopping feeding.

I was told that night feeding breast milk can cause cavities because of the natural sugars, and now I'm so worried. Did anyone else's baby get cavities from sleeping while feeding? Please tell me if I need to stop night feeds.

I totally get it, you are doing your best to feed your baby and then someone tells you it might ruin their teeth! Don't feel guilty. Just start gently cleaning their tiny teeth with a soft baby brush, and they will be absolutely fine.

My niece had this issue recently. The dentist told us that while breast milk has antibodies that protect, it still contains lactose which can contribute to decay if combined with poor oral hygiene. Just wipe their mouth after feeds and avoid letting them sleep with a bottle.

Actually, breast milk itself isn't the main culprit, yaar. It is when milk sits on the teeth overnight with other solid foods that bacteria start acting up. Just brush their teeth twice a day and you are sorted, no need to panic.

We ignored my son's slight tooth discoloration thinking breast milk is completely safe, but it turned into severe cavities that required dental treatment under anesthesia. Please don't ignore any white spots on the teeth. Take your baby to a pediatric dentist for a checkup early.
