Community Water Fluoridation

Community water fluoridation is the process of adjusting the fluoride level that occurs naturally in a community's water to the optimal level for preventing tooth decay as proven by hundreds of studies conducted over fifty years throughout the world. Adults as well as children benefit from drinking fluoridated water throughout their lives.

Continued progress has been made in the area of water fluoridation for the state of Arizona. In 1990, the cities of Phoenix and Glendale began water fluoridation, joining Tempe, Bisbee and Chandler. Although Tucson voters approved water fluoridation in 1994, technical problems have delayed its implementation. Communities in Arizona that have chosen to adjust the fluoride level in their drinking water include:

  • Bisbee
  • Mesa
  • Chandler
  • Phoenix
  • El Mirage
  • Tempe
  • Gilbert
  • Yuma
  • Glendale
