• Water fluoridation, long considered a public health success for preventing tooth decay, is now debated due to its possible link to lower I.Q. scores in children. 

• A recent JAMA Pediatrics study reviewed 74 studies from 10 countries, revealing an inverse relationship between fluoride exposure and cognitive abilities.

A reassessment of fluoride’s role in public health remains critical.
