Fluoride controversy
The fluoride controversy or fluoridation centers around artificially adding sodium fluoride to public water and dental products. It first became a political issue in the 1950s raised by American Nationalists like Robert Edmondson. The issue originated in that calcium fluoride exists naturally in foods and the water of certain wells. People found that those who drank well water with large amounts of calcium fluoride had protection from tooth decay.
In response, people started adding sodium fluoride to water supplies and dental products. The controversy around fluoridation is that it is using man-made extremely toxic sodium fluoride rather than natural nontoxic calcium fluoride. Yet when main sources like the mass media and Wikipedia speak about the controversy, they will not mention the different types of fluoride and depict it as the same type.

Toxicity of calcium fluoride
CaF2 is classified "not dangerous." With regards to inhalation, the NIOSH-recommended concentration of fluorine-containing dusts is 2.5 mg/m3 in air.[1]
Toxicity of sodium fluoride
The lethal dose for a 70 kg (154 lb) human is estimated at 5–10 g.[1] Sodium fluoride is classed as toxic by both inhalation (of dusts or aerosols) and ingestion.[2] In high enough doses, it has been shown to affect the heart and circulatory system.
In the higher doses used to treat osteoporosis, plain sodium fluoride can cause pain in the legs and incomplete stress fractures when the doses are too high; it also irritates the stomach, sometimes so severely as to cause ulcers. Slow-release and enteric-coated versions of sodium fluoride do not have gastric side effects in any significant way, and have milder and less frequent complications in the bones. In the lower doses used for water fluoridation, the only clear adverse effect is dental fluorosis, which can alter the appearance of children's teeth during tooth development; this is mostly mild and is unlikely to represent any real effect on aesthetic appearance or on public health.
Sodium fluoride causes brain damage
The 2006 National Academy of Science, EPA, Dr. Vyvyan Howard – a PhD fetal pathologist, The National Center for Biotechnology, and studies around the world have found for decades that sodium fluoride lowers intelligence and the chemical builds up in the brain.[3][4][5] In 2014, researchers from Harvard School of Public Health (HSPH) and China Medical University in Shenyang studied the effect of sodium fluoride consumption and found it lowers childrens' IQs by 7 points.[6][7][8]
Sodium fluoride inhibits the enzyme acetylcholinesterase in the brain, which is involved in transmitting signals along nerve cells. Studies on rats given sodium fluoride found the rats had symptoms resembling attention deficit-hyperactivity disorder and fluoride accumulated in the pineal gland, which produces serotonin and melatonin. It also combines with aluminum and builds aluminum up in the brain which encourages Alzheimer’s disease.[9]
