Grand Rapids, the test case for fluoridation

In January of 1945, Grand Rapids became the first city to introduce fluoride to its water supply. Was this a net positive or a net negative? It depends on who you ask.

The American Dental Association has established that a .7 parts per million solution of fluoride is the optimal for the prevention of tooth decay, and many West Michigan dentists agree. There is no doubt that the often catastrophic tooth issues that plagued our grandparents are much rarer in American society now, and there is certainly a correlation between children with access to fluoridated water and lowered rates of tooth decay.

The Center for Disease Control considers the fluoridation of American water supplies to be a huge public health victory. About 70 percent of American municipal water is currently fluoridated.

There are a number of groups that exist to advocate for removing fluoridation from water as well, and it's useful to consider their arguments before coming to any conclusion.

One of the biggest arguments against water fluoridation is that essentially it's a rather uncontrolled science experiment on a captive population. By dosing whole communities with fluoride governments ensure access to this chemical, but do these populations know what is going into their body? What grade is the fluoride being added? Apparently it's not pharmaceutical grade fluoride.

Secondly, consuming fluoride isn't necessary to reduce cavities - this is why topical use in toothpaste serves teeth adequately. Taking in regular amounts of fluoride over time has largely unknown long-term health effects, and they are largely unknown because they are largely unstudied. But there does appear to be some evidence that fluoride exposure increases risk for infertility, arthritis, lowered I.Q., thyroid issues, bone problems, and bone cancer.

What's more, not everyone's exposure to fluoride is the same, since people drink different amounts of water and children, particularly babies fed on formula have higher fluoride intake. Furthermore, while poor children without access to other sources of water such as bottled water are more exposed to fluoride in the water, they still have higher rates of dental decay than other children. Dental problems have steadily decreased in American populations, but they've also decreased in European populations without access to fluoridated water.

There are many more arguments against fluoridation, and few people are aware of them since fluoride is viewed as a wonder chemical and actively advertised. Grand Rapidians are increasingly interested in exploring options for better and more natural food options and healthcare. They care about what they put into their bodies. It would be worthwhile for them to be aware of what is going into their bodies without permission as well - and to ask questions.
