Water Fluoridation Myths and Facts

MYTH: “Fluoride doesn’t belong in drinking water.”

FACT: Fluoride occurs naturally in water, though rarely at the optimal level to protect teeth.

  • It’s already there. Fluoride exists naturally in virtually all water supplies and even in various brands of bottled water. If the people making this statement truly believed it, they would no longer drink water or grape juice – or eat shellfish, meat, cheese or other foods that contain trace levels of fluoride.
  • What’s at issue is the amount of fluoride in water. There are proven benefits for public health that come from having the optimal level of fluoride in the water – just enough to protect our teeth. In 2011, federal health officials offered a new recommended optimal level for water fluoridation: 0.7 parts per million. That’s our goal: getting just enough to help all of us keep our teeth longer.

MYTH: “Adding fluoride is like forcing people to take medication”

FACT: Numerous scientific studies and reviews have recognized fluoride as an important nutrient for strong healthy teeth.

  • Fluoride is not a medication. It is a mineral, and when present at the right level, fluoride in drinking water has two beneficial effects: preventing tooth decay and contributing to healthy bones.
  • There are several examples of how everyday products are fortified to enhance the health of Americans – iodine is added to salt, folic acid is added to breads and cereals, and Vitamin D is added to milk.

MYTH: “Our city council can save money by ending fluoridation of our water system.”

FACT: Fluoridation is one of the most cost-effective health strategies ever devised.

  • A community that stops fluoridating or never starts this process will find that local residents end up spending more money on decay-related dental problems. Evidence shows that for most cities, every $1 invested in fluoridation saves $38 in unnecessary treatment costs.

MYTH: “Fluoridation is a ‘freedom of choice’ issue. People should choose when or if they have fluoride in their water.”

FACT: Fluoridation is a public health measure where a modest community-wide investment benefits everyone.

  • Fluoride exists naturally in virtually all water supplies, so it isn’t a question of choosing to get fluoride. The only question is whether people receive the optimal level that’s documented to prevent tooth decay.

MYTH: “We already can get fluoride in toothpaste, so we don’t need it in our drinking water.”

FACT: Fluoridated water is the best way to protect everyone’s teeth from decay.

  • The benefits from water fluoridation build on those from fluoride in toothpaste. Studies conducted in communities that fluoridated water in the years after fluoride toothpastes were common have shown a lower rate of tooth decay than communities without fluoridated water.
  • The CDC reviewed this question in January 2011. After looking at all the ways we might get fluoride – including fluoride toothpaste – the CDC recommended that communities fluoridate water at 0.7 parts per million. Any less than that puts the health of our teeth at risk.
  • Fluoride toothpaste alone is insufficient, which is why pediatricians and dentists often prescribe fluoride tablets to children living in non-fluoridated areas.

MYTH: “Fluoridation causes fluorosis, and fluorosis can make teeth brown and pitted.”

FACT: Very high fluoride concentrations can lead to a condition called fluorosis. Nearly all fluorosis in the U.S. is mild. This condition does not cause pain, and does not affect the health

  •  Nearly all cases of fluorosis are mild – faint, white specks on teeth – that are usually so subtle that only a dentist will notice this condition. Mild fluorosis does not cause pain, and it does not affect the health or function of the teeth.
  • The pictures of dark pitted teeth that anti-fluoride opponents circulate show severe cases of fluorosis, a condition that is almost unheard of in the U.S. Many of these photos are from India, and the reason is natural fluoride levels over there that are dramatically higher than the level used in the U.S. to fluoridate public water systems.
  • In 2011, the CDC proposed a new level for fluoridation – 0.7 parts per million – that is expected to reduce the likelihood of fluorosis while continuing to protect teeth from decay.

MYTH: “Fluoridation causes cancer and other serious health problems.”

FACT: Leading health and medical organizations agree: fluoridated water is both safe and effective.

  • The American Academy of Family Physicians, the Institute of Medicine and many other respected authorities endorse water fluoridation as safe. The Centers for Disease Control and Prevention reports that “panels of experts from different health and scientific fields have provided strong evidence that water fluoridation is safe and effective.”
  • More than 3,200 studies or reports had been published on the subject of fluoridation. Even after all of this research, the best that anti-fluoride groups can do is to claim that fluoride could cause or may cause one harm or another. They can’t go beyond speculating because the evidence simply doesn’t back up their fears.

MYTH: “Fluoridation doesn’t reduce tooth decay.”

FACT: Anti-fluoride groups cite many “studies” that were poorly designed, gathered unreliable data, and  were not peer-reviewed by independent scientists.

  • An analysis of two similarly sized, adjacent communities in Arkansas showed that residents without access to fluoridated water had twice as many cavities as those with access to fluoridated water.
  • In New York, Medicaid recipients in less fluoridated counties required 33% more treatments for tooth decay than those in counties where fluoridated water was prevalent.
  • The benefits of fluoridation are long-lasting. A recent study found young children who consumed fluoridated water were still benefiting from this as adults in their 40s or 50s.

      Only 5% of the world and only 3% of Europe fluoridate their drinking water. They have read the science from the last 25 years and learned that swallowing fluoride is ineffective for teeth and dangerous to health.
      It is illegal for a doctor or a dentist to force anyone to take a drug or a chemical. It should be illegal for the government as well.
      The public water supply should never have been used to deliver a drug. Once added to the water you cannot control the dose, you cannot control who gets the medicine, no doctor is checking side effects such as individual susceptibly and it violates individual’s right to informed consent. Medical professionals should be ashamed to support such a crude and unethical practice which results in cancer, thyroid & pineal gland damage, broken hips from brittle bones, lowered IQ, kidney disease, arthritis and other serious health problems.

    2. This article is fantastic as I’m constantly criticized for being pro-fluoridation and now I have some facts and figures to further support my beliefs. Kudos!

      Let’s get the facts straight. Fluoride is completely safe. It occurs naturally in water. The process of fluoridation is simply adjusting the amount of fluoride (down or up) so that people can get the greatest health benefit possible.

      It is not a drug. It is not medicine. And once carefully and accurately adjusted in the water, it does not need to be “controlled”.

      It might be true that some European countries don’t fluoridated their water. But let’s not misrepresent the reason why. These countries fully understand the health benefits of fluoride and choose to fluoridate their table salt rather than water.

      Fluoride and water fluoridation do not cause cancer or lower IQ. These false and unfounded claims have been refuted time and again and sound science has repeatedly demonstrated the enormous oral health benefit of water fluoridation.

      Does this writer (who is not from Vermont nor Hartford, by the way), really think that the VT Department of Health, national health agencies like the Centers for Disease Control and Prevention, the American and Vermont Dental Association, the American Academy of Pediatrics and so many more organizations of this stature are secretly trying to poison the entire country? That they really know fluoride is dangerous and ineffective, but they just don’t care?

      Community water fluoridation is supported by these public health and medical organizations because it is a proven and safe way to prevent cavities. The common sense people of Hartford know this, too.
