Delaware has a long history of promoting community water fluoridation to improve the oral health of its residents. The state has consistently maintained high levels of access to fluoridated water, with recent data showing that 85.9% of the population served by community water systems had access to this important public health measure in 2018. This article will delve into the key statistics and facts about water fluoridation in Delaware, highlighting its impact on dental health and the state’s efforts to expand access.

Here are some of the most notable statistics about water fluoridation in Delaware:

  • In 2018, 85.9% of Delaware’s population served by community water systems had access to fluoridated water, significantly higher than the national average of 73%.
  • Delaware passed a mandatory law in 1998 requiring fluoridation, changing from a previous requirement for a referendum in 1974.
  • Community water fluoridation can save communities anywhere from $1.10 to $135 for every $1 invested, with per capita annual benefits ranging from $5.49 to $93.19.

Delaware’s Commitment to Fluoridation

Delaware has demonstrated a strong commitment to water fluoridation over the years. The state provides funds for fluoridation equipment for three years from the date of the passage of the 1998 mandatory fluoridation law, showcasing its dedication to promoting this public health measure.

  • From 1992 to 2018, the percentage of Delaware’s population with access to fluoridated water increased from 67.4% to 85.9%.
  • Delaware’s 2018 fluoridation rate of 85.9% is significantly above the national average of 73%, indicating a higher coverage compared to the national level.

The Impact of Fluoridation on Oral Health

Community water fluoridation has been identified as a major factor in reducing rates of tooth decay in the United States. Since its implementation, each generation of Americans has enjoyed better oral health than the one before.

  • Fluoride helps prevent tooth decay by making teeth more resistant to acid attacks from plaque bacteria and sugars.
  • Studies have shown that fluoridation can reduce tooth decay by 20-40% in children and adults.

National Fluoridation Statistics

While Delaware boasts impressive fluoridation rates, it’s important to consider the national context as well. Here are some key national statistics:

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

Delaware’s high fluoridation rates and ongoing efforts to promote this public health measure demonstrate the state’s commitment to improving the oral health of its residents. As more communities recognize the benefits of fluoridation, it’s likely that access to this important dental health tool will continue to grow, both in Delaware and across the nation.
