Minnesota Water Fluoride: Updated Statistics

Water fluoridation is a widely recognized public health measure that has been instrumental in reducing tooth decay and improving oral health across the United States. Minnesota, in particular, has demonstrated a strong commitment to this practice, with nearly all of its population having access to fluoridated water. Let’s take a closer look at the current state of water fluoridation in Minnesota and its impact on public health.

Minnesota boasts one of the highest percentages of population with access to fluoridated water in the country. The state has consistently maintained this high level of coverage over the years, reflecting its dedication to promoting oral health through community water fluoridation.

• In 2018, 98.8% of Minnesota’s population served by public water systems had access to fluoridated water.
• Minnesota’s fluoridation coverage of 98.8% is significantly higher than the national average of 72.7% in 2020.
• Every dollar spent on fluoridation by a community in Minnesota saves $20 in avoided dental treatment costs.

Consistent Access to Fluoridated Water

Minnesota has maintained a consistently high level of access to fluoridated water over the years.

• The percentage of Minnesota’s population with access to fluoridated water has remained at 98.8% in 2018, 2016, 2014, and 2012.
• Even as far back as 2006, 98.7% of the state’s population had access to fluoridated water.

Legislation and Public Health Support

Minnesota’s high fluoridation rates can be attributed to strong legislative support and a focus on public health.

• Minnesota Statute 144.145 requires the fluoridation of water in all municipal water supplies, except where natural levels are sufficient.
• Community water fluoridation prevents at least 25 percent of tooth decay in children and adults, even with the widespread availability of fluoride from other sources, such as toothpaste.

Fluoride Regulation and Monitoring

To ensure the safety and effectiveness of water fluoridation, Minnesota has strict regulations and monitoring practices in place.

• Municipal water supplies must adjust fluoride levels to maintain a concentration prescribed by the state commissioner of health.
• Water systems monitor performance, collect daily samples, and submit monthly reports to the Minnesota Department of Health (MDH).

National Fluoridation Statistics

While Minnesota excels in water fluoridation, it’s important to consider the national context as well.

• In 2020, 72.7% of the U.S. population on community water systems, or 209,145,650 people, had access to fluoridated water.
• The Healthy People 2030 objective aims for 77.1% of people served by community water systems to receive water with the optimum level of fluoride.

Minnesota’s commitment to water fluoridation has resulted in nearly universal access to this important public health measure, setting a strong example for other states to follow. By prioritizing oral health and implementing effective policies and monitoring systems, Minnesota continues to champion water fluoridation as a means to prevent tooth decay and improve the well-being of its residents.
