Recently, some residents in Buffalo, NY, have been pushing to have fluoride reintroduced into their water supply. They claim that the absence of fluoride has led to various health issues. However, their demand for reintroducing what some experts call a “silent poison” is puzzling and highlights how misinformation and a lack of awareness can push people toward supporting harmful policies.
Fluoride, widely used in water fluoridation and toothpaste, is often marketed as essential for dental health. However, beneath this public health narrative lies a darker reality: fluoride is a toxic substance that can harm the human body, even in small amounts. So, why are people eager to fight for something that may harm them in the long run? Let’s explore this issue.
What is Fluoride, and Why Is It Dangerous?
Contrary to popular belief, fluoride does not strengthen teeth. In fact, prolonged fluoride exposure can weaken tooth enamel over time, making teeth more vulnerable to decay. Additionally, fluoride poses significant health risks, including neurological, skeletal, and thyroid issues. Long-term exposure through water and other products can have serious consequences.
- The Chemical Nature of Fluoride: Fluoride is a halogen, part of a chemical family that includes chlorine, bromine, and iodine. These reactive elements can interfere with biological processes. Fluoride has been classified as a neurotoxin, meaning it can damage the brain and central nervous system.
- The Dangers of Prolonged Exposure: Even in small doses, fluoride accumulates in the body. It binds with calcium, damaging bones and teeth, potentially causing a condition known as skeletal fluorosis. This condition makes bones less elastic and more prone to fractures. Additionally, teeth may become mottled and discolored (dental fluorosis). Prolonged exposure to fluoride has also been linked to reduced IQ levels in children. Studies show that children in high-fluoride areas have significantly lower cognitive function compared to those in low-fluoride regions.
- Neurological and Developmental Risks: In 2012, a study by Harvard School of Public Health revealed a strong link between fluoride exposure and reduced IQ in children. The study reviewed 27 international studies and concluded that fluoride negatively impacts cognitive development. This neurotoxicity is particularly alarming for young children, whose brains are still developing.
- Thyroid Dysfunction: Fluoride can also harm the thyroid gland, which regulates metabolism, growth, and development. Fluoride was once used to treat hyperthyroidism due to its ability to reduce thyroid function, but it can also lead to hypothyroidism, causing fatigue, weight gain, and depression. Over time, fluoride accumulates in the thyroid, impairing its function and overall health.

The Lawsuit: A Case of Misinformed Citizens?
In 2023, Buffalo residents filed a class-action lawsuit after learning the city had quietly stopped adding fluoride to its water in 2015. Outraged citizens claimed the lack of fluoride harmed public health, especially among children. The lawsuit argues that the city’s decision violated the residents’ right to a healthy environment, as outlined in New York’s Green Amendment.
While the plaintiffs seek damages and the reintroduction of fluoride, this case reflects a deeper issue: fluoride itself may pose greater harm than good. Despite claims that the absence of fluoride caused health problems, growing scientific evidence highlights fluoride’s toxicity. Even with Buffalo planning to resume fluoridation by summer 2024, the controversy raises important questions about fluoride’s role in public health.
The Global Shift Away from Fluoridation
Many countries, including Germany, Sweden, Japan, and the Netherlands, have entirely stopped water fluoridation, recognizing the risks far outweigh the benefits. Despite widespread promotion, the belief that fluoride prevents tooth decay is increasingly criticized due to its harmful effects on overall health.
Fluoride in Toothpaste: A Hidden Danger
Fluoride isn’t just in our water—it’s in nearly every toothpaste on the market. Adults and children alike are encouraged to use fluoride toothpaste twice daily. However, warnings on toothpaste tubes caution against swallowing it, signaling potential dangers. Fluoride absorbed through the tissues in the mouth can enter the bloodstream, leading to the same health risks associated with fluoridated water.
A Chemical That Doesn’t Belong in Our Lives
Given the evidence of fluoride’s dangers, it’s shocking that people are demanding its reintroduction into their water supply. This reflects how flawed science and misguided government recommendations have misled the public. Instead of advocating for more fluoride, we should focus on removing it from our water, toothpaste, and other products. Fluoride is toxic, and its prolonged exposure leads to serious health consequences, including lower IQs, thyroid dysfunction, and skeletal issues.
Conclusion
Fluoride has long been promoted as essential for dental health, but its risks far outweigh any supposed benefits. The recent lawsuit in Buffalo highlights the urgent need for greater public awareness about fluoride’s dangers. Rather than advocating for its continued use, we should be demanding its removal from our daily lives. By understanding the science behind fluoride’s harmful effects, we can take steps to protect ourselves and our communities.
It’s time to end fluoride’s toxic legacy once and for all.
