Summary
Robert F. Kennedy Jr. announced that a Trump administration would prioritize removing fluoride from public water systems, a position at odds with major health organizations like the CDC, the American Dental Association, and the American Academy of Pediatrics, all of which endorse water fluoridation as safe and beneficial for dental health.
Despite Kennedy’s controversial stance on health and environmental issues, which includes previously debunked claims linking vaccines to autism, Trump has praised his passion, stating that Kennedy would have significant freedom to influence health policy if Trump were elected.
Those concerns are for unrealistically high doses though. The last sentence of the abstract you linked:
Calling concerns about the safety of fluoridated water “founded” is a bit of a stretch.
