Study shows fluoride may not help teeth at all
Fluoridation of public water supplies offers no meaningful health benefit, according to a new study comparing cavity rates in two different Ontario provinces.
"Fluoridation is no longer effective," said Hardy Limeback, head of the University of Toronto's preventive dentistry program. Considering all the dangerous effects of fluoride consumption, in fact, he concluded that fluoridation is "more harmful than beneficial."
Fluoridation, the addition of fluoride to public water supplies, has been popular in First
World countries for more than six decades, and the U.S. Centers for Disease Control classifies it as one of the greatest health breakthroughs of the 20th century. Fluoridation proponents claim that the mineral strengthens teeth, thereby cutting cavity rate by 20 to 40 percent.
Yet the practice has always been controversial, primarily due to fluoride's undisputed status as a highly reactive neurotoxin. More recent studies suggest that ingestion of fluoride can damage the thyroid gland and reduce children's IQ levels. In 2006, a study published in Cancer Causes and Control found that exposure to large amounts of fluoridated water made seven-year-old boys four times more likely to develop a rare bone cancer known as childhood osteosarcoma.
