Since 1950, the American Dental Association has repeatedly assessed the safety of community water fluoridation. Based on the overwhelming weight of credible scientific evidence, there is no reason for concern.
As with other nutrients, fluoride is safe when consumed properly. Of the hundreds of credible scientific studies on fluoridation, none has shown any health problems associated with the consumption of optimally fluoridated water (such as in Boulder).
No charge against the safety of fluoridation has ever been substantiated scientifically.
The total intake of fluoride from air, water and food, in an optimally fluoridated community like Fort Collins, does not pose significant health risks.
Fluoride, at the concentrations found in optimally fluoridated water (as in Boulder), is not toxic. Acute fluoride toxicity occurring from the ingestion of optimally fluoridated water is impossible. Many substances in widespread use are very beneficial in small amounts, but are dangerous in very large doses — such as salt, chlorine and even water itself!
Dental fluorosis — a white mottling of the teeth — is the only known possible consequence of water fluoridation. It affects only a small proportion of very young children. Once teeth have developed, a person cannot get it. In any event, dental fluorosis is not a health problem, but a cosmetic one, and often not even noticeable. Despite claims that dental fluorosis weakens teeth, the mottling in fact represents a strengthened area of a tooth!
Reviews of the scientific knowledge about fluoridation confirm that there are NO known links between fluoridation and:
cancer
hip fractures
bone disease of any sort, especially crippling skeletal fluorosis
AIDS
allergic reactions
genetic abnormalities
Down Syndrome
central nervous system disorders, including effects on intelligence
Alzheimer’s
any cardiovascular disease
kidney diseases
problems with the human immune system
impaired thyroid function
disruptions of human enzyme activity
There is no scientific evidence that optimal levels of fluoride affect the quality of water. All ground and surface water in the United States contain some naturally occurring fluoride.
Allegations that fluoridation causes corrosion of water delivery systems are not supportable. Routine water plant operations correct any occurrence of corrosive agents in drinking water.
The concentrations of arsenic and lead are below the EPA-established limits in Boulder water, so fluoridation does not have any toxicological effects related to either of these substances.
The facts are all on the side of continuing fluoridation.
