Water Fluoridation

Since community water fluoridation began in 1945, it has been demonstrated to be a safe and cost-effective way to prevent tooth decay. It has been identified by the Centers for Disease Control and Prevention as one of 10 great public health achievements of the 20th century.

Water fluoridation protects teeth in two ways:

  • When delivered through the water supply to children during the tooth forming years.
  • Through direct contact with teeth throughout life.

Hundreds of millions of Americans now receive fluoride through their community water.
