Here is a link to a lot of peer reviewed journals about the effect of fluoride on Bone Density and Bone Strength that seems to show that fluoride to strengthen bones does not have a great outcome:

"Opposition’s Response
Yes. The Journal of American Medical Association (JAMA) links hip fractures and fluoridation in four different issues since 1990. Studies published in the Journal in August 1992, specifically states that their objective was to “test the effect of water fluoridated to 1 ppm on the incidence of hip fractures.” Their study demonstrated a link between hip fractures in the elderly and water fluoridated at 1 ppm, the so-called ‘optimal dose.’ “Hip fractures, (according to the report) are the second most common cause for admission (of elderly) to nursing homes accounting for approximately 60,000 admissions per year.”
“Each year in the U.S. about 250,000 people over age 65 suffer hip fractures and 25% die within three months.” (Chemical & Engineering News, July 30, 1990.)
" … we recently reported the ecological association of discharge rates for hip fracture and water fluoride levels in 39 county districts in England. … there appears to be a positive association between fluoride levels of county water supplies and fracture discharge rates. This ecologic association is consistent with a recently published study and others in progress." (Journal of the American Medical Association (JAMA) July 24, 1991.)
“We found a … significant increase in the risk of hip fracture in both men and women exposed to artificial fluoridation at 1 ppm, suggesting that low levels of fluoride may increase the risk of hip fracture in the elderly.” (Journal of the American Medical Association (JAMA) Aug. 12, 1992.)
“Thus, adjusting for major individual risk factors, this study suggests a deleterious effect of fluorine in drinking water on the risk of hip fractures, even for moderate concentrations of fluorine, and no effect on other kinds of fractures.” (See 18-1: “Fluoride and Hip Fracture,” JAMA, Vol. 273, No. 10, March 8, 1995, and “Hip Fracture Rates are Much Higher in People Residing in Fluoridated Communities” - chart).
“More recently, attention has shifted to lower dosages of fluoride, such as found in fluoridated water. There are now at least eight studies that showed an increase of hip fracture incidence in fluoridated compared to unfluoridated communities. They are summarized here.” (See 18-2: “Brief Account of the Fluoridation/Hip Fracture Problem,” by John R. Lee, M. D., June 30, 1995, for details on these eight studies).
" … many studies (demonstrate) adverse effects to bone caused by fluoride at levels to which the majority of the U.S. population are exposed. … the (Environmental Protection) Agency needs to take immediate action to prevent further injury from occurring to our aging population that result in fluoride induced hip fractures." (William Marcus, Ph.D., EPA scientist, statement to EPA Office of Drinking Water, July 29, 1991.)
“Based on data from the National Academy of Sciences, current levels of fluoride exposure in drinking water may cause arthritis in a substantial portion of the population long before they reach old age.” (Robert J. Carton, Ph.D., former EPA scientist.)
“A review of recent scientific literature reveals a consistent pattern of evidence-hip fractures, skeletal fluorosis, the effect of fluoride on bone structure, fluoride levels in bones and osteosarcomas-pointing to the existence of causal mechanisms by which fluoride damages bones. … and that there is negligible benefit from ingesting fluoride …” (See 18-3: “New Evidence on Fluoridation,” by Mark Diesendorf, Institute for Sustainable Futures, University of Technology, Sydney; John Colquhoun, Department of Education, University of Auckland, Auckland; Bruce J. Spittle, Department of Psychological Medicine, University of Otago Medical School, Dunedin; Douglas N. Everingham, Former Federal Minister for Health, Canberra; and Frederic w. Clutterbuck, Medical Practitioner, Queensland).
Women in high fluoride communities have much earlier and much worse osteoporosis than in low fluoride communities. There was “no protective effect (on bone mass or fracture) with higher fluoride” but more fractures were reported. (American Journal of Nutrition, 44:889-98, 1986.)
Dr. Saul Genuth, director of the radioimmunoassay laboratory at Cleveland’s Mt. Sinai Hospital, said he “regretfully joined in the endocrinologic and metabolic drugs advisory committee’s unanimous opinion that fluoride has yet to prove its worth in the treatment of postmenopausal osteoporosis.” (See 18-4: “FDA Committee Spurns Fluoride,” in Medical World News, Nov. 13, 1989)."
Fluoride’s benefit for teeth is topical application, that is putting it in direct contact with teeth, not the ingestion of Fluoride which does not get into teeth enamel other than when it passes through the oral cavity. The only time ingestion may have a benefit is when very young children ingest fluoride when developing their teeth but Fluoride in this case can have undesirable neuro developmental effects.
