Feds To Cut Fluoride Levels In US Tap Water

Controversial additive linked to splotchy teeth, brittle bones

LOS ANGELES (CBS/AP) — Is loss of bone density and other potentially harmful side effects worth saving the American public a few extra cavities?

Federal health officials no longer think so, which is why they plan to lower the recommended levels for fluoride in water supplies — the first such change in nearly 50 years.

A recent government study found 2 out of 5 adolescents have tooth streaking or spottiness because of too much fluoride, which can be both a naturally-occurring mineral and an industrial pollutant.

In some extreme cases, teeth can even be pitted by the mineral — though many cases are so mild only dentists notice it. The problem is generally considered cosmetic.

Health officials note that most communities have fluoride in their water supplies, and toothpaste has it too. Some kids are even given fluoride supplements.

The U.S. Department of Health and Human Services is proposing changing the recommended fluoride level to 0.7 milligrams per liter of water. And the Environmental Protection Agency will review whether the maximum cutoff of 4 milligrams per liter is too high.

The standard since 1962 has been a range of 0.7 to 1.2 milligrams per liter.

The Centers for Disease Control and Prevention reports that the splotchy tooth condition, fluorosis, is unexpectedly common in kids ages 12 through 15. And it appears to have grown much more common since the 1980s.

“One of the things that we’re most concerned about is exactly that,” said an administration official who was not authorized to speak publicly before the release of the report. The official described the government’s plans in an interview with The Associated Press.

But there are other concerns, too. A scientific report five years ago said that people who consume a lifetime of too much fluoride — an amount over EPA’s limit of 4 milligrams — can lead to crippling bone abnormalities and brittleness.

That and other research issued Friday by the EPA about health effects of fluoride are sure to re-energize groups that still oppose adding it to water supplies.

The American Dental Association released a statement applauding the government announcement to change fluoride guidance.

Fluoride is a mineral that exists naturally in water and soil. About 70 years ago, scientists discovered that people whose supplies naturally had more fluoride also had fewer cavities. Some locales have naturally occurring fluoridation levels above 1.2. Today, most public drinking water is fluoridated, especially in larger cities. An estimated 64 percent of Americans drink fluoridated water.

Portland, Ore., is one of the largest cities that doesn’t fluoridate its water.

Bill Zepp of the Oregon Dental Association said the city’s anti-fluoridation activists will embrace the recommended fluoride changes “as some type of win.”

Maryland is the most fluoridated state, with nearly every resident on a fluoridated system. In contrast, only about 11 percent of Hawaii residents are on fluoridated water, according to government statistics.

Fluoridation has been fought for decades by people who worried about its effects, including conspiracy theorists who feared it was a plot to make people submissive to government power.

Those battles continue.

“It’s amazing that people have been so convinced that this is an OK thing to do,” said Deborah Catrow said Friday. She successfully fought a ballot proposal in 2005 that would have added fluoride to drinking water in Springfield, Ohio.

Reducing fluoride would be a good start, but she hopes it will be eliminated altogether from municipal water supplies.

Catrow said it was hard standing up to City Hall, the American Dental Association and the state health department. “Anybody who was anti-fluoride was considered crazy at the time,” she said.

In New York, the village of Cobleskill in Schoharie County — west of Albany — stopped adding fluoride to its drinking water in 2007 after the longtime water superintendent became convinced the additive was contributing to his knee problems. Two years later, the village reversed the move after dentists and doctors complained.

What’s in your water? Check out statistics from the CDC on local fluoridation levels.

In March, 2006, the National Academy of Sciences released a report recommending that the EPA lower its maximum standard for fluoride in drinking water to below 4 milligrams. The report warned severe fluorosis could occur at 2 milligrams. Also, a majority of the report’s authors said a lifetime of drinking water with fluoride at 4 milligrams or higher could raise the risk of broken bones.

Late last year, lawyers for the Fluoride Action Network, Beyond Pesticides, and Environmental Working Group threatened legal action if the EPA did not lower its ceiling on fluoride.

In Europe, fluoride is rarely added to water supplies. In Britain, only about 10 percent of the population has fluoridated water. It’s been a controversial issue there, with critics arguing people shouldn’t be forced to have “medical treatment” forced on them. In recent years, the UK has tried to add fluoride to communities with the worst dental health but there’s still considerable opposition.

In the early years of fluoridation in the United States, the range of levels was created because people in warmer climates drank more water, therefore getting more fluoride than cooler regions. Over time, that difference leveled out with air conditioning, the senior administration official said.

Fluorosis has generally been seen as the primary down side of fluoride.

According to the CDC, nearly 23 percent of children ages 12-15 had fluorosis in a study done in 1986 and 1987. That rose to 41 percent in the more recent study, which covered the years 1999 through 2004.

“We’re not necessarily surprised to see this slow rise in mild fluorosis,” Dr. William Kohn, director of the CDC’s division of oral health, said in a recent interview.

Health officials have hesitated to call it a problem, however. In most kids, it’s barely noticeable; even dentists have trouble seeing it, and sometimes don’t bother to tell their unknowing patients.

Meanwhile, the U.S. prevalence of tooth decay in at least one tooth among teens has declined from about 90 percent to 60 percent. Health officials call water fluoridation one of the 10 greatest public health accomplishments of the last century.

“One of water fluoridation’s biggest advantages is that it benefits all residents of a community — at home, work, school, or play. And fluoridation’s effectiveness in preventing tooth decay is not limited to children, but extends throughout life, resulting in improved oral health,” said HHS Assistant Secretary for Health Dr. Howard Koh, in a statement.

Indeed, many health leaders continue to be worried about cavities, particularly among poor families with kids who eat a lot of sweets but don’t get much dental care.

Secretary Kathleen Sebelius could make a final decision on details of the changes within a few months, the administration official said.

    People who want fluoride in their food can take fluoride supplements.Not thanks for me.

    People should quit using toothpaste too it is meant to wreak your teeth! Use baking soda – cheaper and much better for ya!

  • nyscof

    More than 3,200 professionals (including over 290 dentists) urge the US Congress to stop water fluoridation citing scientific evidence that fluoridation, long promoted to fight tooth decay, is ineffective and has serious health risks.

    Dental fluorosis was a known harmful side effect from the start of fluoridation and parents and children had a right to know. Why was this information not shared with every home before fluoridation began? Those who wanted fluorides for their children could have asked for alternative methods, which would have given those who did not, freedom of choice to refuse.
    Already Doctors are very strict about patient information on drugs, and consumer information guidelines are more stringent with food additives. Why was information on side effects of water fluoridation not given to the public?
    If a dentist sees fluorosis they are obliged to inform the patient or carer or patient. It is a defect in the teeth as shown as far back as 1940 when Drs. M.C. and H.V. Smith stated in American Journal of Public Health “that although mottled teeth are more resistant to onset of decay, they are structurally weak……”. Parents and children need to know this from the dentist.
    It is time to be open and transparent on the whole picture of the grave mistake that is water fluoridation, and stop this policy now.

      If you have read the history you will know the fluoridation had nothing to do with teeth. During the atomic Manhattan project back in the 40’s millions liters of fluoride laced water was used for uranium processing. There was so much illness amongst the military that and the general public were becoming increasingly angry.
      Powerful corporations did what they have been doing in the US since that time and during Ronald Regan’s time later with total freedom from the people. They employed Mr American Publicity himself. The master of deception, Edward Bernays, to convince the public that water fluoridation was safe and effective (Their parrot catch cry!) for teeth. Fluoride then had a safe image instead of a destructive toxic image. You can dress an angry wolf up in sheep’s clothing but it is still an angry wolf! Fluoride is arguably responsible for more pain and suffering in the US and other countries that the US convinced should introduce it that the US alone has a myriad of joint and soft tissue diseases including hyperthyroidism that the best scientists around the world are proving is directly attributed to fluoride poisoning. You have to revolt against corporations not the least of which is Colgate Palmolive. They make billions of $ world wide from this evil toxic waste. For every dollar they spend being magnanimous in universities and third world countries they make billions poisoning humans and animals. During the second world war the Russians and the Germans used fluoride in the prison camps they thought to improve teeth but what they discovered was that it made humans docile and subservient. Do you really believe that corporations responsible for putting it into 60% of America’s water don’t know that? And finally better teeth is totally attributed to better nutrition, it has nothing whatsoever to do with fluoride.

    Diversionary, misleading, hiding the culling of U.S.Americans from 300,000,000 to 500,000. The health & safety issue is overwhelmed by politics.

  • James Rogers

    Feds should eliminate all fluoridation activity. You did not report the issue accurately.

  • Anaconda

    This is just idiotic…Since when does INGESTING fluoride help your teeth in anyway?! I hate how the government and corporations think they can hide the truth from American citizens!!
