It is a scenario playing out nationwide. From Oregon to Pennsylvania, hundreds of communities have in recent years either stopped adding fluoride to their water supplies or voted to prevent its addition. Supporters of such bans argue that people should be given the freedom of choice. The broad availability of over-the-counter dental products containing the mineral makes it no longer necessary to add to public water supplies, they say. The Centers for Disease Control and Prevention says that while store-bought products reduce tooth decay, the greatest protection comes when they are used in combination with water fluoridation.

The outcome of an ongoing federal case in California could force the Environmental Protection Agency to create a rule regulating or banning the use of fluoride in drinking water nationwide. In the meantime, the trend is raising alarm bells for public health researchers who worry that, much like vaccines, fluoride may have become a victim of its own success.

The CDC maintains that community water fluoridation is not only safe and effective but also yields significant cost savings in dental treatment. Public health officials say removing fluoride could be particularly harmful to low-income families — for whom drinking water may be the only source of preventive dental care.

“If you have to go out and get care on your own, it’s a whole different ballgame,” said Myron Allukian Jr., a dentist and past president of the American Public Health Association. Millions of people have lived with fluoridated water for years, “and we’ve had no major health problems,” he said. “It’s much easier to prevent a disease than to treat it.”

According to the anti-fluoride group Fluoride Action Network, since 2010, over 240 communities around the world have removed fluoride from their drinking water or decided not to add it.

    Very little of our tap water actually touches human teeth.

    Very little of our tap water actually touches human stomachs too, but we still make sure it isn’t filled with amoebas.

      Without chlorination people would get sick and possibly die. Amoebas & bacteria can enter our bodies when showering or even flushing a toilet - via aerosolization. Chlorination is also important for the water infrastructure itself, and to prevent buildup within home pipes and appliances.

      Should we put multi-vitamin compounds in our drinking water too? It is strange that this one thing is added to water vs the host of other compounds which are shown to benefit human health.

        Sure, why not? If they can be absorbed by the body that way and do some good, what’s the problem?

          Do you consider water to be medicine, or a resource? Why don’t we add caloric value to our tap water too, for the sake of malnutrition in impoverished communities?

            Because not everyone benefits from extra calories, but as long as you don’t include vitamins that you can’t take too much of as long as it is in small quantities, what’s the harm?

              I was being facetious and think your argument is completely preposterous, but continuing for fun. Let’s say you are dictator of your loyal subjects, and decide to medicate their water with… vitamins, including copper. What if someone is sensitive to added copper, either because of damage to their copper plumbing, copper cookware, or a metabolic issue? What if someone is working outdoors in the summer heat and consumes 2 gallons of water per day, but begins to experience symptoms of copper toxicity due to the volume of water intake? The water is excreted, but our bodies do not excrete most excess vitamins, such as copper. This copper intake then causes an imbalance/deficiency of zinc and subsequently magnesium.

              Should we add prozac/SSRIs to our water to thwart depression and make the populous happier?

              Most of the world doesn’t medicate their water, and their citizens are surprisingly healthier than us in the US & Australia where we “medicate” our water. How about we give people access to clean, pure water and let them supplement as they & their doctors see fit?

                I like how you ignored the “as long as you don’t include vitamins that you can’t take too much of as long as it is in small quantities” and moved on to “what if someone takes too much?”

                  You’re ignoring the overarching debate, but fine I’ll address your nit-picky distraction.

                  “Small” is a relative term, and to the amounts that would be harmless in all situations would have negligible health benefits, to the point of questioning “why bother”. Also even small quantities add up, such as the example of 2-gallon consumption on a hot day. What isn’t controversial or subjective, though, is pure water.

                  The simplest solution is usually best - instead of a one-size-fits-all “medicated” water approach, just take a multivitamin that works best for your individual biology and preferences… assuming you can’t consume foods which contain the variety of compounds our bodies need, being the ideal solution. Even the USDA recommendations for vitamins & minerals are mere guesstimated guidelines which varies per individual & lifestyle.

                    How do you know all of this? From where did you get your pharmacology degree?
