Can Breast Milk Cause Cavities in My Baby’s Teeth?

While breast milk is a wonderful source of nutrition, it naturally contains sugars like lactose. If these sugars remain on baby teeth for long periods—especially overnight—they can feed bacteria, leading to early childhood caries.

The American Academy of Pediatric Dentistry recommends a first dental visit by age one or when the first tooth erupts.

To help prevent cavities, gently wipe or brush your baby’s teeth after feedings.

Talk to your pediatrician about when to wean nighttime feeding. At NexGen Dentistry in National City, we’ll guide you through brushing techniques and fun routines. Regular visits help catch concerns early and keep your little one smiling!
