Fluoride and Water Fluoridation

SOURCE www.factcheck.org
Fluoride, at the right dose, can reduce tooth decay and has been added to tap water in the U.S. since 1945. While some claim fluoride is neurotoxic and harms IQ, experts and studies show conflicting results. Fluoride is safe at recommended levels and plays a crucial role in dental health.

Key Points

  • Water fluoridation has been recommended since 1962 in the U.S.
  • Fluoride exposure from various sources can lead to dental fluorosis
  • Experts have differing views on the association between fluoride and IQ

Pros

  • Fluoride at the right dose reduces the risk of tooth decay
  • Water fluoridation endorsed by CDC and various expert groups
  • Helps improve dental health, especially in children

Cons

  • Some studies suggest potential association between fluoride exposure and reduced IQ
  • Debate on neurotoxicity of fluoride at high doses
  • Concerns about dental fluorosis and skeletal problems at high fluoride levels
