Community water fluoridation not linked to lower birth weight, large US study finds

A new study from Columbia University Mailman School of Public Health finds that community water fluoridation (CWF) is not associated with significant changes in birth weight—a widely accepted indicator of infant health and a predictor of later-life outcomes. The findings provide reassurance about the safety of fluoridated drinking water during pregnancy. The results are published in JAMA Network Open.
