IADR 2017: Lower water fluoridation level effective in preventing caries
March 24, 2017 -- SAN FRANCISCO - Reducing community water fluoridation to 0.7 mg/L appears to be effective at reducing fluoride exposure while still preventing caries, according to research presented at the International Association for Dental Research (IADR) annual meeting.
Helen Whelton, BDS, MDPH, PhD.
A team of scientists from Ireland and the U.K. compared the caries incidence rates before and after Ireland lowered the recommended water fluoridation level from 0.8-0.9 mg/L to 0.6-0.8 mg/L in 2007. They found that the lower fluoridation rate did not increase caries levels.
"Caries levels did not increase following the reduction in fluoride levels, and there was no increase in caries between 2002 and 2013/2014," said Helen Whelton, BDS, MDPH, PhD, in her presentation at the IADR annual meeting.
Dr. Whelton is a professor of dental public health and preventive dentistry and the dean of the University of Leeds School of Dentistry in the U.K.........................
.......In addition, they found that caries levels were still dramatically lower for kids in fluoridated counties than those living in counties without community water fluoridation. In fact, living in an area with fluoridated water reduced the odds of a child having caries by about 46%.46% - do we believe it?

Don't believe it. For one, they didn't include income. Low-income children always have more tooth decay regardless of fluoridation status. I don't know where they got that 46% figure. I'm thinking it's creative math because what the charts depict is that in 2014 there's a small difference between tooth decay rates in 5 year olds in Fl vs Non-Fl areas (.07 or .08 to 1.4 respectively) or about 1/3 to 1/2 tooth saved over their lifetime.
In 12 year olds, there's only a difference of six tenths of a tooth "saved" in fluoridated Cork and Kerry compared to non-fluoridated Cork and Kerry. We have no evidence that this "study" was peer-reviewed or published.
Further, a very recent newspaper report out of Ireland reported "A leading Irish dentist said that more children than ever are undergoing procedures to remove decayed teeth before the age of four."
