"The available data, responsibly interpreted, indicate little or no beneficial effect of water fluoridation on oral health." - Dr. Kathleen Thiessen, 2006 National Research Council panelist (2011)

The author of that study, a vocal fluoridationist, compared data from 2004/5 to data from 2013/14 to claim increase since cessation in 2011. There was data from 2009/10 and when you compared that data to the earlier and later data, the greatest increase in cavities was from BEFORE they took the fluoride out, and the control town did worse. It is a put up job and inconsistent with a much larger study from British Columbia as well as every other valid study.
