Is fluoride bad for you?

Wait. Did you just ask “Is fluoride bad for you”? What kind of question is that?

After all, we’ve all been putting fluoride on our teeth since we were kids. Fluoride supposedly makes our teeth stronger and more resistant to cavities….right?

Regardless, the debate on whether or not fluoride is actually healthy for us has become increasingly heated in recent years. When considering whether or not fluoride is bad for you, it’s important to point out that this has been quite a controversial topic for decades.

Dental professionals have recommended the use of fluoride to children and adults as part of basic daily dental care for a long time. Due to the purported benefits of fluoride, municipal water supplies routinely add it to their water. Authorities want to ensure that people are getting enough fluoride to support the health of their teeth.

However, in recent years, more and more people have been asking themselves this question: is fluoride bad for you?

What is Fluoride?

Fluoride occurs naturally in soil, plants, rocks, water, and the air. It is also present in your teeth and bones. The fluoride present in dental products and drinking water is a synthetic fluoride.

How Does Fluoride Work?

Fluoride purportedly benefits the teeth by:

  • Altering enamel structure in children under 7 and strengthening it against acid
  • Creating an oral environment that is resistant to acid
  • ​Making plaque bacteria unable to produce acid

The Complicated History of Fluoride

In 1901, dentist Frederick McKay discovered that fluoride is beneficial for teeth.

Moreover, through his work with children in the Colorado Springs area, he noticed that many area children had brown stains on their teeth. At the same time, these children appeared to have quite strong teeth.

Eventually, officials in Colorado Springs uncovered a large amount of naturally occurring fluoride in its water supply. Therefore, they concluded that this caused the mottled brown stains on the teeth, now known as dental fluorosis.

Further investigation of this phenomenon led to the understanding that fluoride aids in the process of remineralization. Remineralization is a process that occurs naturally. In this process, saliva repairs enamel by neutralizing acid before the formation of cavities can occur.

In the 1940s, the Center for Disease Control conducted research studies to further explore the relationship between fluoride and its effects on the teeth. The results of these studies indicated that fluoride reduces cavities by 50 to 70 percent.

Then, in 1962, the CDC officially recommended adding fluoride to public water supplies. The recommended level of fluoridation range at that time was 0.7 to 1.2 milligrams per liter.

Proctor & Gamble was the first company to offer fluoride in their toothpaste. After conducting a multi-million dollar research study on cavity prevention in children, they determined that 50 percent of the participants had decreased cavities from fluoride.

Based on these results, they released Crest toothpaste in 1955, the first toothpaste to contain fluoride. The ad campaign slogan was “Look, Mom! No cavities.”

From that point onward, it became common knowledge that fluoride is necessary to maintain strong teeth and reduce cavities.

​​​​Fluoride Use Today

Ask a dentist “is fluoride bad for you?” and you’ll likely get a funny look (or a dirty look).

Nearly all dentists and the American Dental Association support the daily use of fluoride in toothpaste, mouthwashes, and as part of routine dental visits. They insist that fluoride is both effective and safe.

Furthermore, school personnel also give periodic fluoride rinses. The official CDC statistics on the use of fluoridated water show that 75 percent of the population receives water fluoridation.

The Fluoride Debate

Regardless of the dental health community’s support of fluoride, many individuals, independent scientists, and some dentists have been speaking out in recent years about their concerns regarding the possible risks of fluoride. Professionals are finally questioning the side effects of fluoride.

Their opinions range from the belief we should completely ban the use of fluoride to the view that our current level of use is particularly excessive, especially with regard to its inclusion in public water supplies.

Critics of fluoride believe that individuals should be allowed to choose what they put into their bodies and at an amount that makes them comfortable.

Check out the list below to see some of the arguments against fluoride.

  • ​​Fluoride is naturally occurring in water; it’s unnecessary to add more
  • ​People have the right to choose whether they ingest fluoride
  • ​Different people may need different amounts
  • ​Current levels might be dangerous
  • ​Harmful to the environment
  • ​Fluoride is a neurotoxin at high doses
  • ​Excessive exposure can lead to health problems

In 2015, the U.S. government lowered the recommended fluoridation range for the first time to 0.7 milligrams per liter of water. Concerns regarding dental fluorosis due to fluoride toxicity sparked this change. Some suggest that once the level of fluoride in the body has resulted in visible effects on the teeth, it should also be assumed that the body, as a whole, is in a state of fluoride toxicity.

Ways Fluoride Can Impact Your Health

Research has provided conflicting evidence regarding the benefits of fluoride use. While results have indicated an association between the use of fluoride and a decline in dental cavities, other studies have shown that the benefits are rather minimal.

Furthermore, one study found that the rates of dental cavities have also declined in countries that do not have fluoridated water, which seems to suggest that we don’t really know the exact reason why cavities are declining.

Therefore, we should be cautious when attempting to attribute this success to fluoride alone. We also must weigh this information against what we know about the risks associated with excessive fluoride intake.

To further answer the question, “is fluoride bad for you?”, we have compiled a list of the ways fluoride may impact your health below:
