Breast and bottle feeding as risk factors for dental caries: a systematic review and meta-analysis

Do bottle fed children have more dental caries in primary dentition than breastfed children?

Four studies showed that bottle fed children had more dental caries (p<0.05), while three studies found no such association (p>0.05).

The scientific evidence therefore indicated that breastfeeding can protect against dental caries in early childhood. The benefits of breastfeeding until age two is recommended by WHO/UNICEF guidelines.
