Health Effects of Fluoride

  • Skeletal fluorosis at levels above 4 mg/L (bone pain, joint stiffness)
  • Dental fluorosis in children at levels above 2 mg/L
  • At 0.7 mg/L (water fluoridation level), helps prevent tooth decay
  • Possible thyroid effects at high chronic exposure

Health risk severity: Moderate. Governed by the National Primary Drinking Water Regulations.

How Fluoride Gets Into Drinking Water

  • Intentional water fluoridation (0.7 mg/L target, beneficial)
  • Natural deposits in certain rock formations
  • Industrial discharge (aluminum, fertilizer production)
  • Naturally elevated in some groundwater (especially arid regions)
