How does fluoride harm us?

Answer 1

Thanks for the question. Fluoride is dangerous. If you have in excess of 3.4g you will die promptly. Please be aware of this. It is a very dangerous substance. Proffesor J. Ellis. Ex-Manager of the Distribution of Fluoride Ltd.

Yes, fluoride in water can be bad for you.

Children who drink fluoridated water are at increased risk of developing fluorosis, a defect of the permanent teeth resulting in staining and, in severe cases, substantial corrosion of the enamel. According to the Centers for Disease Control, about 30 percent of children who drink fluoridated water have some degree of fluorosis. The National Academy of Sciences has also raised concerns about fluoride exposure and bone fractures in the elderly, skeletal fluorosis, thyroid hormone disruption, and neurotoxicity (including effects on IQ). In addition, there is evidence that fluoridated water is linked to osteosarcoma, an often fatal form of bone cancer, in boys.

Evidence-based Scientific ViewFluoride is not bad for you. It is considered by most public health experts to be one of the major advances in public health of the last century. Unfortunately, it has become politicized and the target of internet conspiracy theorists. What one must remember is that everything is toxic (even water and oxygen) at high enough levels. "The dose makes the poison" and so when reading the claims of people citing support to the claims of the evils of fluoride one must pay attention to make sure they are not citing industrial exposures, high dose supplements, etc etc.

• It does reduce tooth decay dramatically.
• It saves society money by promoting better health.
• It is associated with less gun disease, which may be a contributing factor in Heart disease.
• Nearly all dental fluorosis (mottling of the teeth from too much fluoride) is from eating toothpaste or taking too much supplementation in pill form, not from drinking water.
• There is no credible evidence that it causes cancer.
• There is no credible evidence that fluoride from drinking water causes osteoporosis or fractures (taking high dose pills can and studies of drinking water are on-going).
• There is no credible evidence that it causes birth defects, ADD or other toxicity at the doses found in water.

Answer 3

In 2006 the National Research Council published a report entitled "Fluoride in Drinking Water: A Scientific Review of the EPA's Standards." The review panel found that hydrofluorosilicic acid if ingested in sufficient quantity has been linked with preventable diseases like Arthritis, Diabetes, osteosarcoma, Alzheimer's, Down's syndrome, osteoporosis, chronic fatigue, and hypocalcemia, that fluoride can cause damage throughout the human organism: cells, skins, bones, joints, ligaments, kidneys, liver, lungs, and intestines. Fluoride may depress the thyroid gland, impair kidney function, and calcify the pineal gland. Fluoride may also cause neurological damage that lowers IQ and combine with aluminum to cause Alzheimer's and dementia. Fluoride can also damage the DNA by causing cells to mutate, which is one of the triggers of cancer.

The amount of fluoride needed to cause these effects is much more than is normally found in fluoridated drinking water. After a study in 1991 by the National Toxicology Program detected an increase in bone tumours among rats exposed to fluoride, numerous studies have been made on the cancer-causing properties of fluoride: by the Public Health Service in 1991 including a study by the National Cancer Institute, by the NRC in 1996 and the CDC in 1999. All studies concluded that water fluoridated to the level recommended does not increase the likelihood of cancer. In fact these and all other studies performed showed that the only significant health risk from fluoridation is dental fluorosis, a discoloration of the teeth.

However the NRC study did suggest that the levels of fluorides in drinking water may be, in some cases due to natural leaching, pesticides and industrial pollution containing fluourides, higher than the recommended amount. In such a case the health risks might be more significant.

The beneficial effect of fluoridated water in preventing tooth decay has been so often demonstrated in the last seventy years that it cannot be seriously doubted. In the minds of most people this far outweighs the disadvantages.

Answer 4

acute toxicity(margin between toxic & therapeutic dose is very narrow)

artritis

bone fracture

teeth deformation

brain defects

thyroidal problems

cancer

cardiovascular disease

dibetes

endocrinal disruption

hypersensitivity

kidney disease

skeletal fluorosis

Answer 5

More toxic than lead, (if swished like in my school) can kill cause its poison, and it wears away teeth enamel and makes the bone stop growing. Not Good !!!!!!!!!!!!!!!! ~By 5th grader

Answer 6

The only disadvantage I can think of is that tou should NOT swallow it. Trust me : (
