Exposure to high levels of fluoride results in a condition known as fluorosis, in which tooth enamel becomes discolored. The condition can eventually lead to badly damaged teeth. The new study found that fluoride intake during a child’s first few years of life is significantly associated with fluorosis, and warned against using fluoridated water in infant formula.
The Centers for Disease Control and Prevention (CDC) is of a similar opinion. According to their website:
“Recent evidence suggests that mixing powdered or liquid infant formula concentrate with fluoridated water on a regular basis may increase the chance of a child developing … enamel fluorosis.”
