Common drinking water toxin may fuel tooth decay in kids

Toxic chemical substances commonly found in drinking water may be fueling tooth decay in children, according to a new study. The researchers found that children who had higher concentrations of a PFAS substance called perfluorodecanoic acid in their blood also experienced more tooth decay. These same toxins have also been linked to health problems that include heart disease, cancer, and thyroid disease.
