NEW YORK, March 15, 2019 /PRNewswire/ -- Researchers report a huge increase in dental fluorosis in the USA in a paper just published in the Journal of Dental Research – Clinical & Translational Research.
Dental fluorosis is a tooth enamel defect caused by excessive fluoride intake during childhood. It appears as white spots or lines in milder cases and pitted and stained enamel in more severe cases. Analysis of the most recently available government data (NHANES 2011-2012 survey) found that 65% of American children now have some degree of dental fluorosis.
The survey found the objectionable degrees of dental fluorosis, termed "moderate" and "severe", in 30.4% of children age 12-15. This was an 8-fold increase from the previous national survey in 1999-2004 that found 3.7% affected.
Paul Connett PhD, director of Fluoride Action Network, noted: "This is compelling evidence that fluoride exposure, linked to lowered IQ in children, has skyrocketed. Fluorosis is a permanent marker of excessive early life exposure to fluoride. The US Public Health Service (PHS) has promoted fluoridation since the 1950s, but now must recognize fluoride exposure is out of control. The emerging evidence of harm to developing brains can no longer be dismissed."
