Fluoridating the public water supply has been common practice for nearly 80 years in the U.S. It’s an acclaimed public health intervention that helps prevent cavities. For just as long, some have raised concerns about the practice that can veer from evidence-based to unsubstantiated conspiracy. An analysis by government researchers, published Monday in JAMA Pediatrics, is adding to the debate. The research found that exposing babies and kids to high levels of fluoride might be associated with neurodevelopmental harm. Frankly, it’s a lot to digest — so we invited health correspondent Pien Huang onto the show to wade through the debate.
