Breastfeeding beyond 24 months may be linked to a higher risk of childhood cavities, according to a 2025 systematic review and meta-analysis.
Researchers analyzed 25 studies involving 19,681 children and found that children breastfed for more than 24 months had a 2.44-fold higher risk of developing early childhood caries compared with those breastfed for shorter durations. Breastfeeding between 12 and 24 months was not associated with a significant increase in cavity risk.
Importantly, the review found an association, not proof that breastfeeding itself causes cavities. Early childhood caries is a multifactorial disease influenced by factors such as nighttime feeding after teeth erupt, inadequate brushing with fluoride toothpaste, frequent sugar exposure, limited fluoride use, and cavity-causing bacteria.
Maintaining good oral hygiene from the eruption of the first tooth, using fluoride toothpaste as recommended, and scheduling regular dental visits remain important for reducing cavity risk.
