Florida has simply banned fluoride in public water, turning into the second state to take action. It’s a part of decadeslong battle that has heated up lately. Native governments debate whether or not it belongs within the water provide. Dad and mom query security. Pseudoscience clouds public notion. Usually, the dialog is framed as a home ideological battle between private liberty and public well being mandates.
As a dentist educated in India and a worldwide well being researcher primarily based in the USA, I’ve noticed the fluoride debate from a broader, international lens. In lots of elements of the world, fluoride isn’t controversial — it’s merely unavailable. Thousands and thousands endure from preventable tooth decay as a result of they lack entry to fluoride, and due to this fact the safety it gives towards oral illness.
In India, I handled sufferers who represented each extremes of the fluoride spectrum. Some rural communities had been uncovered to naturally excessive fluoride ranges, resulting in debilitating skeletal fluorosis. However in lots of city and peri-urban settings, particularly amongst low-income populations, fluoride publicity was just about nonexistent. The results had been seen: superior cavities in kids as younger as 6, power gum infections in adults, and widespread tooth loss among the many aged.
In these settings, fluoridated toothpaste was not all the time inexpensive or obtainable. Water programs had been not often fluoridated. The absence of fluoride was not a well being desire — it was a systemic failure. My sufferers weren’t debating the deserves of fluoridation. They had been residing with the implications of its absence.
This duality formed my understanding of fluoride not as a common good or evil, however as a device — one which should be managed rigorously and distributed equitably.
What to find out about a controversial new research on fluoride and IQ
As we speak, working as a public well being researcher in the USA, I proceed to look at the well being implications of oral care disparities. In some ways, fluoride stays the one preventive dental measure that reaches weak populations who lack common entry to scientific care.
But opposition to fluoride within the U.S. is commonly strongest in well-resourced communities — the place various dental companies are plentiful, fluoride toothpaste is inexpensive, and public skepticism, political distrust, or misinformation can take maintain. For a lot of of those folks, unfluoridated water could not pose an instantaneous threat — they’ve the means to compensate by way of non-public care. However the bans they advocate for lengthen far past their communities, stripping others of a preventive device they can’t simply exchange. Low-income and marginalized populations, significantly Black and Latino communities, expertise disproportionately excessive charges of dental illness and already lack adequate entry to each fluoridated water and inexpensive care.
In these communities, fluoride isn’t an ideological query. It’s a sensible intervention that may scale back the burden of oral illness, which in flip is linked to systemic situations like diabetes, heart problems, and being pregnant issues.
In my present work on HIV and tuberculosis care amongst displaced and migrant populations in Central Asia, oral well being isn’t a part of the care dialog. But oral infections and tooth loss have an effect on vitamin, vanity, immune perform, cardiac well being, and the power to stick to remedy plans.
That is the place American public well being conversations can profit from worldwide perspective. Whereas debates rage about potential overexposure to fluoride, thousands and thousands worldwide nonetheless lack fundamental entry to it. The International South continues to expertise excessive charges of untreated dental illness as a result of infrastructural, financial, and coverage obstacles.
The fluoride debate, due to this fact, isn’t solely about chemistry — it’s about context. The privilege of questioning fluoride’s position exists solely the place different types of care are already accessible. Elsewhere, fluoride represents a vital line of protection.
You will need to query and research each public well being intervention, together with fluoride. However the dominant narrative within the U.S. — typically influenced by misinformation — is prioritizing some folks over others.

Slightly than focusing solely on private autonomy, public well being leaders ought to take into account proportionate universalism: making fluoride obtainable to all however focusing on the best advantages to these most in want. If fluoride is faraway from public water programs, there should be a viable, equitable various, equivalent to sponsored fluoride toothpaste, school-based varnish applications, or group dental sealant initiatives. In any other case, the folks most affected shall be these least in a position to afford non-public care. (This downside is compounded by the brand new effort to ban some fluoride dietary supplements.)
The World Well being Group and quite a few peer-reviewed research proceed to assist fluoride as a secure and efficient public well being measure, significantly the place preventive care entry is proscribed. From Canada to the UK to India, governments proceed to wrestle with balancing public concern towards well being fairness.
I consider the USA has a possibility to guide — not by abandoning fluoride, however by anchoring the dialogue in information, fairness, and empathy. We should not permit coverage to be formed by these with the loudest voices on the expense of these with the best want.
Public well being isn’t about perfection — it’s about progress. Fluoride stays one of many few instruments that, when applied with care, can meaningfully scale back well being disparities. To retreat from it with out substitute isn’t cautious. It’s unjust.
