In 2008, 64.3% of the population served by public water systems
received optimally fluoridated water.

Public water fluoridation practice varies by city and state.(View MMWR chart.)

Water fluoridation was recognized by the Centers for Disease Control and Prevention (CDC) as one of the 10 greatest public
health achievements of the 20th century.

The CDC, the US Task Force on Community Preventive Services, and the Canadian Task Force on Preventive Health Care have all concluded that there is strong evidence that community water fluoridation is effective in preventing dental caries

In 2015, the U.S. Department of Health and Human Services (HHS) finalized its recommendation that community water systems adjust the concentration of fluoride in drinking water to 0.7 mg/L ppm (change from 0.7-1.2 mg/L).

Water filters may alter the fluoride content of community water.

  • Activated charcoal filters and cellulose filters have a negligible effect
  • Reverse osmosis filters and water distillation remove almost all fluoride from water
