A new study in the journal Pediatrics says fillings and sealants used by dentists may expose children to the chemical bisphenol A (BPA), according to an article in U.S. News & World Report.

Research has indicated BPA exposure may be linked to a variety of health issues, including cardiovascular disease, an increased risk for cancer and diabetes, sexual dysfunction and hyperactivity. Particular concerns have centered on risks to the brain, reproductive and behavioral health of children and even fetuses.

The article describes ways to minimize the risks when children are getting fillings or sealants:

Gargling for about 30 seconds following application of a dental sealant will remove any excess BPA derivatives, she explained, and dentists can also clean off the sealant's surface once it has hardened.

BPA expert Scott Belcher, an associate professor of pharmacology at the University of Cincinnati, said the research team's recommendation "is probably the most reasonable choice right now in terms of the tack to be taken."
