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." 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.
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. 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  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 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.
However, fluoride poisoning and fluorosis are still prevalent.[6,25] The main reasons include, but not limited to:
- Ingestion of fluoride-containing toothpaste
- Malfunction of water fluoridation equipment
- It has occurred several times, including an Alaskan incident that sickened nearly 300 people and killed one.
- Inhalation of fluoride dusts/fumes
- Use of coal as an indoor fuel source is still a common practice in China
- 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:
- 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) and start to see negative health effects. To avoid fluoride overdose, read  for the tips of getting fluoride out of water.
In , 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; choose the ones containing xylitol
- Also, see  for the reasons that Dr. Mercola is against gum chewing.
- Based on . chew your gum not longer than 30 seconds if you do.
- Flossing teeth
- Scraping tongue
- Oil pulling or swishing
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:
Mixing your infant formula with nonfluoridated water

- Many felt dental health was an issue to be dealt with at the level of the individual, rather than a solution to be imposed en masse.
- Natural groundwater contains fluoride in varying levels.
- Skeletal fluorosis is caused by prolonged intake of excessive amounts of fluoride through water, food or both. The optimum upper safe limit is not more than 6 milligrams per day.
- High amounts of fluoride over several years can cause brittle bones.
- If you don't use any filter in your water system, your body is the filter.
- Most of fluorides are accumulated in your bones.
- (At 43:40 mark) A combination of nutrients like Magnesium (Mg), Calcium (Ca) and Vitamin C can bind free fluoride ions and help to excrete fluoride from your body more effectively.
- Fluoride replaces the hydroxyls of hydroxyapatite, thereby improving the strength of tooth enamel, but this process can also occur in other active calcifications.

- Since 2006, epidemiological studies have documented six additional developmental neurotoxicants—manganese, fluoride, chlorpyrifos, dichlorodiphenyltrichloroethane, tetrachloroethylene, and the polybrominated diphenyl ethers.
- A meta-analysis of 27 cross-sectional studies of children exposed to fluoride in drinking water, mainly from China, suggests an average IQ decrement of about seven points in children exposed to raised fluoride concentrations
