PRESS RELEASE - Another Blockbuster Fluoridation Report: No Longer Any Significant Reduction of Cavities
• Fluoridation’s effectiveness has declined to almost nothing over the past 50 years
• Authoritative review finds less than 4% reduction in tooth decay
• Only about “one quarter of a tooth” reduction
• Stopping fluoridation is now a no brainer - confirmed risk of lowering child IQ and no significant benefit to teeth. What’s the point?
The Cochrane Collaboration – highly respected for its independent reviews of health interventions – released its updated assessment of water fluoridation for the prevention of dental caries.
After a thorough search and review of available studies, it concluded contemporary evidence doesn’t show a reduction in cavities of more than 4%, and there may be no benefit at all. The report said the average benefit was only about “one quarter of a tooth,” which is one cavity in every four children.
The review found a large decline in fluoridation effectiveness over the past 50 years.
While 1970s studies showed young children in fluoridated areas may have saved as many as 4 cavities in their baby teeth, the most recent study from 2022 found a reduction of only 0.16 decayed teeth.
This represents a 25-fold decline in fluoridation effectiveness to an amount so small as to be of questionable clinical or public health value, and likely a net economic loss rather than benefit.
The Cochrane report’s main conclusions were:
“Adding to water may slightly increase the number of children who have no tooth decay in either their baby teeth or permanent teeth. However, these results also included the possibility of little or no difference in tooth decay.”
“We could not be sure whether adding fluoride to water reduced tooth decay in children’s permanent teeth.”
“We were unsure whether there were any effects on tooth decay when fluoride is removed from a water supply.”
“We were unsure if fluoride reduces differences in tooth decay between richer and poorer people.”
The large decline in fluoridation’s effectiveness over the past 50 years is illustrated by graphs created by FAN’s Science Director, Chris Neurath, from the report’s data.
