Something in plastics may be weakening kids’ teeth


Over the last two decades, the share of children with defective tooth enamel has been rising. It “now affects 15 to 20 percent of children 6 to 9 years old,” says Sylvie Babajko of the French National Institute of Health and Medical Research in Paris. A chemical used to make many plastics could be partly to blame, her team now concludes. The researchers showed that the chemical, BPA, can trigger the same problem in lab rats that had been showing up in children. BPA is present in many foods (from packaging), rubs off of many store receipts and is an ingredient in some sealants applied to kids’ teeth.
