PFAS (IMAGE) West Virginia University Caption Being exposed to PFAS--a class of chemicals found in drinking water--has been linked to higher rates of cancer, heart disease, thyroid dysfunction and other conditions. WVU School of Dentistry researchers R. Constance Wiener and Christopher Waters studied whether PFAS exposure is also associated with tooth decay. They found that higher concentrations of a particular PFAS correlated to greater rates of tooth decay in children.
