Health Effects of Element Fluorine (F)

Most countries in modern-day Western Europe have opted out of artificially fluoridated water, dismissing the practice for what it really is: mass medication.[1,14,35] This includes: Austria, Belgium, Finland, France, Germany, Hungary, Luxembourg, Netherlands, Northern Ireland, Norway, Sweden, Switzerland,[2] Scotland,[3] Iceland, and Italy. A 2003 survey of over 500 Europeans from 16 countries concluded that "the vast majority of people opposed water fluoridation".[4,32]

Mekorot, Israel's national water company also states, "In the South of the country, it is unnecessary to add fluoride because it is found naturally in the water."[5] Yes, Fluorine (F) is the 24th most abundant element in the universe and the 13th most abundant within the Earth's crust.

In this article, we will examine the positive and negative health effects of Fluorine.

What's Fluorine?

Fluorine is the lightest halogen and the most electronegative element. Fluorine doesn't hang around for long in the environment— it normally exists as negatively charged fluoride ions in combination with other elements.[15] It requires great care in handling as it is extremely reactive and poisonous. While a few plants and bacteria synthesize organofluorine poisons, fluorine has no metabolic role in mammals.

What Is "F" Used for?

The fluoride ion, when directly applied to teeth, is claimed to reduce decay based on some scientists. For this reason, it is used in toothpaste and water fluoridation, which are also recommended by U.S. Public Health Service, CDC and ADA.  However, water fluoridation was materialized not really due to the true concern for the public dental health, but because the greedy businessman wanting to dump a waste by-product from the manufacturing of aluminum.  Read [35] for the history of it.

What Are the Issues?

Soluble fluorides are moderately toxic. Chronic excess fluoride consumption can lead to skeletal fluorosis, (note that it's not just dental fluorosis) a disease of the bones that affects millions in Asia and Africa.[6,7] Based on a report[9] of National Research Council, it cites severe dental fluorosis (i.e., teeth appear discolored and sometimes pitted) can result from fluoride overdose. Severe dental fluorosis has been found in about 10 percent of children in communities with water fluoride concentrations at or near 4ppm.
That's why each water district tries its best to maintain an optimal fluoride level. For example, SFPUC (the San Francisco Public Utilities) has a CDHS (California Department of Health Services) approved fluoridation control range of 0.8 – 1.5 mg/L, with an optimal fluoride level of 1.0 mg/L.

However, fluoride poisoning and fluorosis are still prevalent.[6,25] The main reasons include, but not limited to:
  • Ingestion of fluoride-containing toothpaste[1]
  • Malfunction of water fluoridation equipment
    • It has occurred several times, including an Alaskan incident that sickened nearly 300 people and killed one.[8]
  • Inhalation of fluoride dusts/fumes
    • Use of coal as an indoor fuel source is still a common practice in China[16]
    • The 1783 eruption of the Laki volcano in Iceland is estimated to have killed approximately 25% of the Icelandic population, and 50–80% of livestock, as a result of fluorosis and sulfur dioxide gases.
  • Drinking water with naturally occurring levels of fluoride in excess of the recommended safe levels
    • In India, the most common cause of fluorosis is fluoride-laden water derived from deep bore wells.
  • Consumption of fluoride from the drinking of tea[17,25]
    • In Tibet, excessive consumption of poor-quality pu-erh tea is reported to cause fluorosis.

Other health risks of "F" include:[14]
  • Sodium fluoride can compromise cellular health and result in adverse thyroid function and adverse neurological effects.[7,13,30,31]
  • Fluoride was theorized to make people more docile and easy to control, and thus it was added to water supplies in occupied regions and POW camps by Nazi's.


We're not just getting fluoride from our tap water and tooth brushing. Bottled water often contains fluoride, as do sodas, juices, and many foods manufactured using fluoridated water. Between all of these sources, you can easily exceed the recommended dose of daily fluoride consumption (i.e.,  not more than 6 milligrams per day)[22] and start to see negative health effects. To avoid fluoride overdose, read [18] for the tips of getting fluoride out of water.

In [12], dentists like Dr. Cole suggest brushing teeth twice a day, for two minutes each time. If you drink tea in the morning like I do, consider reducing brushing to once a day. If you only do it once, bedtime is best, since that is when your mouth salivates less, allowing cavity-causing substances to take hold. If you skip brushing after meals, try the following alternatives:
  • Rinsing your mouth with water
  • Chewing gums
    • But, do avoid gums containing aspartame sweetener;[20] choose the ones containing xylitol[21]
    • Also, see [23] for the reasons that Dr. Mercola is against gum chewing.
    • Based on [36]. chew your gum not longer than 30 seconds if you do.
  • Flossing teeth
  • Scraping tongue 
  • Oil pulling or swishing[28]

If you have infants in the households, try breast-feeding your kids as much as possible. If you choose feeding them with infant formula, do follow ADA's advice:
