Officials with the Iowa Department of Public Health (IDPH) today (Monday), said 10 Iowa communities have been awarded fluoride certificates by the Association of State and Territorial Dental Directors on behalf of the U.S. Centers for Disease Control and Prevention (CDC) and American Dental Association (ADA). Fluoridation is the adjustment of fluoride in the water to an optimal level for preventing tooth decay.

Denison and Winterset were among the communities receiving a 50-year award for maintaining continuous community water fluoridation from 1964-2014.

Today, approximately 75 percent of Americans served by public water systems drink optimally-fluoridated water. Fluoridated water safely and inexpensively reduces tooth decay by 25 percent in children and adults. The CDC has recognized community water fluoridation as one of the ten great public health achievements of the 20th Century and recommends water fluoridation as a safe, effective, and inexpensive method of preventing tooth decay.
