Water fluoridation is a critical public health measure that helps prevent tooth decay and promote oral health. Ohio has been a leader in this effort, with a long history of providing fluoridated water to its residents. This article will explore the current state of water fluoridation in Ohio, highlighting key statistics and the impact on public health.

Ohio has consistently maintained a high percentage of its population with access to fluoridated water, well above the national average. The state’s commitment to this important public health measure is evident in its legislation and the support from public health organizations. Let’s take a closer look at some of the most notable statistics:

  • In 2018, 92.5% of Ohio’s population served by public water systems had access to fluoridated water, significantly higher than the national average of 72.7% in 2020.
  • Ohio is ranked #10 among the states for the percentage of its population receiving fluoridated water.
  • More than nine out of 10 people living in Ohio who are served by public water supplies have fluoridated water.

Ohio’s High Fluoridation Rate

Ohio has maintained a high percentage of its population with access to fluoridated water over the past decade.

  • The percentage of Ohio’s population with access to fluoridated water has remained relatively steady, hovering around 92.5%.

Comparison to National Averages

Ohio’s fluoridation rate is well above the national average, demonstrating the state’s strong commitment to this public health measure.

  • Nationally, 72.7% of the U.S. population on community water systems received fluoridated water in 2020.
  • In 2018, 63.4% of the total U.S. population and 73.0% of the population on community water systems received fluoridated drinking water.

Legislation and Public Health Support

Ohio’s high fluoridation rate is supported by legislation and public health organizations.

  • Ohio’s Fluoridation Law, passed in 1969, requires public water systems that serve more than 5,000 persons to fluoridate. Communities served by these systems have the option to be exempt from the law through a special vote.

Public Health Impact

Community water fluoridation is a significant public health measure for reducing tooth decay and promoting oral health.

  • The CDC has identified community water fluoridation as one of the ten great public health achievements of the 20th century.

Ohio’s high percentage of population with access to fluoridated water is a testament to the state’s commitment to improving oral health. By maintaining this level of access, Ohio is helping to prevent tooth decay and promote better overall health for its residents. As the state continues to prioritize this important public health measure, it sets an example for other states to follow in the fight against oral disease.
