HUSZTI dental care
Fluoride is a naturally occurring chemical that has been added to public water supplies for nearly a century. In 1944, Michigan's own Grand Rapids was the first city in the world to take this step. Today, 70% of the world's population living in more than 133 countries benefit from the practice of adding low-levels of fluoride to the water their residents drink.
Decades of research has shown that fluoride reduces cavities, increases oral health and has no realistic downsides. In fact, the U.S. Centers for Disease Control put the addition of fluoride to water systems — along with vaccines, recognition of smoking's health hazards, motor vehicle and workplace safety regulations — in the top 10 greatest public health achievements of the 20th Century. It's safe, inexpensive, and effective in preventing tooth decay no matter what the economic status or access to care.
And yet, remarkably, probably part of the trend of distrust in public institutions that has roiled the United States for many years, removing fluoride from the water is on the table.
Here's what you need to know.
In the early 1900s, oral cavities were commonplace among the population. Yet dentists noticed that there were some areas of the country where they were not. Researchers looked into the issue and found that, in some parts of the country, fluoride was naturally present in the water supply. They also noticed that many people who lived in those areas had discolored teeth. It turned out fluoride — more accurately really high levels of fluoride — were responsible for that too. After much study, scientists and doctors determined that a very low level of fluoride in water would prevent cavities and all the issues that come with them. In the United States, the recommended ratio is 0.7 milligrams fluoride per liter. Individual states can set their own levels, up to the maximum level of 4.0 milligrams per liter.
Some people have suggested there are side effects from hip fractures to bone cancer to delays in brain development in fetuses and young children. All studies have proven there is no relationship to these concerns and fluoride at low levels.
In some countries where fluoride naturally occurs at very high levels people can develop a condition whereby their bones become very brittle. There are no areas in the United States where that is a concern, according to Johns Hopkins Bloomberg School of Public Health.
While it may be good to question some institutions and long-held beliefs, questioning the efficacy of fluoride in public water supplies should not be one of them. It would be irresponsible to remove it.
