Following a recent blog on Birmingham’s fluoridated water supply, a thoughtful reader said she could not understand why hip fractures would increase when fluoride was accumulated, adding to bone mass. An online search followed.
The most relevant findings (10th page, Google search!) follow this summary of points made in the blog: Birmingham – together with only 10% of the UK’s population – accepted the expense of adding fluoride to its water supplies in 1964. Scientific research gives cause for concern on several counts:
- Thyroid malfunction
- Childhood cognitive impairment
- Effect of fluoride accumulation on bone structure over many years
- The effects of cumulative fluoride intake
“Fluoride has been used in the past and is possibly one of the oldest drugs available for managing osteoporosis. It would actually produce dramatic effects in changing the radio-graphic appearance of bones by making them appear much denser.The actual bone mass seemed to increase but it did not promote any mineralization (depositing of calcium) resulting in poor bone quality and hence chances of fractures are high,” says Gurinder Bedi, Senior Consultant, Department of Orthopedics, Fortis Hospital.
Vivek Logani, Chief of Joint Replacement Surgery at Paras Hospital in Gurgaon, agrees to the side effects of fluoride intake, “It is widely recognized that fluoride therapy for osteoporosis adds mass to bones but produces inferior bones. Numerous studies show that fluoride may cause not only increased skeletal fragility (more non-vertebral fractures such as hips) but also osteomalacia (deficiency of bone mineralization).” Infants, elderly, people with deficiencies of calcium, magnesium and vitamin C and those with cardiovascular and kidney problems are more susceptible to the toxic effects of fluoride and its compounds. According to experts, lower body pain, prolonged pain, body stiffness and inability to walk are some of the symptoms of bones being affected by high fluoride concentration.
“Due to this counterproductive action of fluoride on the strength and elasticity of the bone, the Food and Drug Administration of United States has rejected the use of fluoride for treatment of osteoporosis,” Logani added.

Cancer rates in the ten largest fluoridated cities in the United States and in the ten largest nonfluoridated cities were found to be the same before fluoridation began. After 20 years, the ten fluoridated cities had 10% more cancer deaths than the nonfluoridated cities. The cancers were found in the tongue, mouth, pharynx, esophagus, stomach, colon, rectum, pancreas, larynx, bronchi, and lungs. Hip fractures in two cities in Utah were compared: fluoridated Brigham City and nonfluoridated Cedar City. In the fluoridated (1 ppm) city, the hip fracture rate was twice as high as in the nonfluoridated city, in women around age 75. Men aged 80-85 also had twice the hip fracture rate in fluoridated Brigham City.
The insidious nature of fluoride toxicity is that it does not cause bone density loss as found in osteoporosis by bone scans, but causes an increase in bone density with no clinical benefit. Fluoride makes both bones and teeth more brittle. Early reports of supposed benefits of fluoridation to bone were quoted without citing later corrections or retractions. Dr. A. K. Susheela of the India Institute of Medical Sciences in New Delhi found that fluoride severely disrupts formation of bone matrix, inhibiting the hardening of bones. She found that about 20 countries in the world have serious health problems due to excess fluoride. Her work showed that high levels of fluoride in drinking water were associated with birth defects, stillbirths, and early infant mortality . . .
Water fluoridated to 1ppm fluoride is not safe in the general population. How much of the toxicity results from the arsenic and heavy metal contamination in the newer fluoridating agents is not yet known. Additionally, certain populations such as patients with diabetes or renal impairment are at increased risk, especially if they drink more than average amounts of water. A study comparing 25 young adults with fluorosis against 25 matched controls showed very significant impairment of glucose tolerance in those with fluorosis, which, however, was reversible when water with low fluoride levels was given . . . –
