Discover the Countries That Don’t Fluoridate Their Water—And the Surprising Reasons Behind It!

With the discussion around water fluoridation heating up in the United States, it’s essential to explore why some countries opt against it, while others have even reversed their fluoridation policies.

In the U.S., about 63% of people—around 209 million—drink fluoridated water. Interestingly, nearly 12 million of those rely on naturally occurring fluoride in their water supply. Critics of fluoridation often highlight that many nations do not add fluoride to their water. But is this accurate, and why do certain countries choose not to fluoridate?

Current Global Perspectives on Fluoridation

In countries like Finland and the Czech Republic, the debate on fluoridation has center-staged, but only a handful cite safety as a primary concern. A study found that, among 11 countries that stopped fluoridation, only two expressed doubts about its effectiveness.

Countries like Italy showcase how unique geological settings can influence fluoride levels. Some regions naturally have fluoride levels reaching up to 30.2 mg/L due to volcanic rock, leading to water treatment efforts to dilute fluoride to meet WHO guidelines of 1.5 mg/L.

Children’s Oral Health and Fluoridation Benefits

Research shows that fluoride can be crucial in preventing tooth decay, especially in areas lacking dental care. Dr. Zoe Zohoori, a public health expert, emphasizes fluoride’s role in reducing health disparities. In her study, she noted stark tooth decay differences between Middlesbrough and Hartlepool in England, where kids in Hartlepool had a significantly lower decayed teeth rate due to natural fluoride in their water.

A recent study in Japan found that children in regions with higher fluoride levels had about a 3.3% lower chance of developing cavities for every 0.1 ppm increase in fluoride. This suggests possible benefits of fluoride in maintaining dental health.

Alternative Approaches to Fluoride Delivery

In some countries, like Thailand, innovative strategies have emerged. Rather than fluoridating water, Thailand provides fluoridated milk to over one million schoolchildren daily. This approach reduces tooth decay significantly and includes educational components promoting dental health.

Salt fluoridation is another method—Switzerland was the pioneer in adding fluoride to table salt back in 1955. While this reduces dental issues, experts like Zohoori caution against promoting salt intake.

Access to Dental Care Matters

Access to dental health services heavily influences countries’ decisions on fluoridation. A 2015 study highlighted that dental care coverage in Europe far exceeds that in the U.S., where fewer than half of the population has dental insurance. This disparity raises concerns about health inequalities if fluoride is removed from the water supply.

The Future of Fluoridation

The WHO recently reported that Europe has the highest rates of dental issues globally. Notably, Calgary, Canada, which discontinued fluoride in its water, reinstated it after seeing increased tooth decay in its community.

As more discussions occur, experts warn that removing fluoride from water could exacerbate health inequalities, disproportionately affecting lower-income communities.
