OBJECTIVE: To determine if there is an association between longer breast-feeding duration and dental caries in healthy urban children. METHODS: We conducted a cross-sectional study of urban children aged 1 to 6 years recruited through The Applied Research Group for Kids (TARGet Kids!) practice-based research network between September 2011 and August 2013. The main outcome measure was parental report of dental caries. RESULTS: The adjusted predicted probability of dental caries was 7%, 8%, 11%, and 16% with total duration of breastfeeding duration of 12, 18, 24, and 36 months, respectively. In the adjusted logistic regression analyses, relative to breastfeeding 0 to 5 months, the odds of dental caries with total breast-feeding duration > 24 months was 2.75 (95% confidence interval 1.61-4.72). CONCLUSIONS: Among healthy urban children, longer breast-feeding duration was associated with higher odds of dental caries. These findings support heightened awareness and enhanced anticipatory guidance for preventive dental care, particularly among children who breast-feed beyond 2 years of age.
