A prominent independent network of researchers recently examined every available study on water fluoridation and found that the practice does not reduce cavities.
The Cochrane Collaboration, a global independent network of researchers, professionals, and patients, narrowed the review down to the most comprehensive, well-designed and reliable papers, before analyzing and publishing their conclusion.
According to Newsweek:
“The review identified only three studies since 1975—of sufficient quality to be included—that addressed the effectiveness of fluoridation in the population at large.
These papers determined that fluoridation does not reduce cavities to a statistically significant degree, says study co-author Anne-Marie Glenny, a health science researcher at Manchester University in the United Kingdom.
