Fluoride in Drinking Water: A Crucial Element for Oral Health
Introduction to Fluoride
Fluoride is a mineral that has been a cornerstone of oral health for decades. It is added to toothpaste, drinking water, and is now a topic of discussion in legislative bills. Two U.S. states have decided to stop adding fluoride to their water supplies, a trend that concerns local dental experts. A new study has revealed the potential consequences of banning fluoride on a larger scale, and the results are alarming.
What Would Happen if the U.S. Banned Fluoride?
Researchers from Brigham and Women’s Hospital and Harvard School of Dental Medicine conducted a study to predict the effects of a nationwide fluoride ban. They analyzed data from the National Health and Nutrition Examination Survey, which includes oral health data from clinical examinations of U.S. adults and children. The study featured 8,484 children and predicted that a fluoride ban would increase dental costs across the U.S. by $9.8 billion within the first five years.
The Cost of a Fluoride Ban
The estimated increase in dental costs is significant, especially considering that it already costs Georgia parents an average of $201,058 to raise a child from infancy to 18 years old. With the added cost of cavities, which averages $191 per cavity, the financial burden on parents would be substantial. The study estimates that within the first five years of a nationwide fluoride ban, there would be 25.4 million more cavities reported in children, representing a 7.5% increase in cases.
Local Dentists Weigh In
A local dentist, Cary Goldstein, spoke to The Atlanta Journal-Constitution in April, warning of the consequences of a fluoride ban. "It will be amazing for our business," he said. "We will have so much work on our hands. We’ve almost put ourselves out of business because fluoride keeps decay down." Goldstein emphasized the importance of preventing major oral health issues down the road, stating that "that small cavity in childhood leads to serious dental work in adulthood."
The History of Fluoride in Drinking Water
It has been 80 years since Grand Rapids, Michigan, became the first U.S. city to fluoridate its drinking water. By 1980, half of the U.S. population was drinking water with fluoride. The Atlanta-based Centers for Disease Control and Prevention (CDC) calls fluoridation "a cornerstone strategy for prevention of cavities in the U.S." that is "a practical, cost-effective, and equitable way for communities to improve their residents’ oral health regardless of age, education, or income."
Why the Push to Ban Fluoride?
Despite the benefits of fluoride, some states have begun to ban it from drinking water. Florida Gov. Ron DeSantis signed a measure prohibiting the addition of fluoride to the state’s drinking water, citing concerns over fluoride overexposure. Utah became the first state to ban fluoride in public drinking water, with all statewide water systems ceasing fluoridation on May 7.
The Risks of Fluoride Overexposure
Fluoride overexposure can lead to fluorosis, causing tooth discoloration. A 2019 review of cross-sectional studies concluded that high doses of fluoride can potentially become neurotoxic to young children, leading to worsened cognitive function. However, the CDC recommends a maximum fluoride concentration of 0.7 mg/L in drinking water, which is 30% less than the high doses observed in the study review.
Conclusion
The study’s findings suggest that fluoridation at safe levels offers both individual and societal benefits that would be at risk if fluoride were to be banned. With the potential consequences of a fluoride ban being so severe, it is crucial to consider the importance of fluoride in maintaining good oral health. As the debate over fluoride in drinking water continues, it is essential to weigh the benefits and risks and make informed decisions about the future of oral health in the U.S.
