Why Is Fluoride Used in Dentistry?
Fluoride has historically been used to help strengthen enamel and reduce cavities. It can:
- Remineralize early signs of decay
- Help make teeth more resistant to acid attacks
- Play a role in lowering cavity rates in communities with poor access to dental care
Because of these properties, fluoride was added to municipal water supplies across the U.S. beginning in the 1940s.
Why We No Longer Support Fluoridating Public Water
At Van Hemert Family Dentistry, we believe in prevention—but also in consent, transparency, and minimizing unnecessary exposure to potentially harmful substances. Emerging science has raised significant concerns about the safety of fluoride—especially for developing children:
- Studies now show that fluoride is a developmental neurotoxin that can lower IQ in children even at relatively low levels of exposure. (Source: Environmental Health Perspectives, Grandjean & Landrigan, 2014)
- A growing number of studies, including NIH-funded research, link prenatal and early childhood fluoride exposure to neurodevelopmental harm. (Source: Bashash et al., 2017; Till et al., 2020)
The “Little Things Matter” video by Dr. Bruce Lanphear (an expert in environmental neurotoxins) beautifully explains how even low-level exposures to substances like fluoride, lead, and mercury can have long-term effects on brain development. (We highly recommend watching it to better understand why “a little” does matter.) Our view:
- Mass medicating the population through the water supply removes informed consent.
- There are safer, targeted ways to prevent cavities without exposing everyone—especially vulnerable populations—to fluoride risks.
What We Offer Instead
Because we want to honor your health and your right to choose, we offer:
- Fluoride-free cleanings and polishing
- Hydroxyapatite products (a natural mineral that strengthens enamel without fluoride)
- Targeted risk assessments—we tailor prevention strategies to your cavity risk, not by blanket policy
- Dietary and remineralization support to naturally fortify your enamel
We still offer fluoride for patients who want it, used selectively and at appropriate strengths—but it’s never our default recommendation.
Common Questions
“Is fluoride safe in small amounts?” Modern research suggests even low-dose fluoride exposure—especially during fetal development and early childhood—can impact neurodevelopment. Like many environmental toxins, there is no truly safe lower limit for some individuals. Our philosophy: When safer alternatives exist, we choose the safer path.
“What is hydroxyapatite and how does it work?” Hydroxyapatite is the main mineral your teeth and bones are made of. Topical products using nano- or micro-hydroxyapatite can rebuild enamel, reduce sensitivity, and protect teeth—without toxic risks.
“Can I still choose fluoride treatments if I want them?” Absolutely. Our role is to inform and empower, not pressure. If fluoride is the right fit for you, we’ll explain how to use it properly and minimize risks.
Our Core Belief
You deserve both protection and choice. We are passionate about helping you make decisions that protect not just your teeth, but your brain, body, and long-term health. Small exposures can matter. And small choices—like choosing safer preventive strategies—can make a big difference over a lifetime. We’re here for the conversation.
