Fluoride added to about 2/3 of US public water supplies is supposed to
reduce tooth decay but these six studies and from dental journals show it hasn’t and, in fact, may have increased the likelihood of rotten choppers.
. “No increase in caries (cavities) was found in Kuopio (Finland) 3
years after the discontinuation of water fluoridation,” according to Caries Research (1). In fact, when Kuopio was compared to a similar never-fluoridated Finnish town, cavity rates in both towns either remained the same or decreased six years after fluoridation was stopped in Kuopio.
· Seven years after fluoridation ended in LaSalud, Cuba, cavities
remained low in 6 to 9 year olds, decreased in 10 to 11 year-olds, significantly decreased in 12 to 13 year olds, while caries-free children increased dramatically, reports Caries Research (2).
· East German scientists report, “following the cessation of water
fluoridation in the cities Chemnitz (formerly Karl-Marx-Stadt) and Plauen, a significant fall in caries prevalence was observed,” according to Community Dentistry and Oral Epidemiology (3)
. Additional surveys in the formerly-fluoridated towns of Spremberg and
Zittau found. “Caries levels for the 12-year-olds of both towns significantly decreased… following the cessation of water fluoridation.”
· Not only did decay rates remain stable during an 11-month
fluoridation break in Durham, NC, between September, 1990, and August, 1991 but dental fluorosis declined in children born during that period, according to the Journal of Dental Research (4)
· In British Columbia, Canada, “the prevalence of caries decreased
over time in the fluoridation-ended community while remaining unchanged in the fluoridated community,” reported in Community Dentistry and Oral Epidemiology. (5)
· In 1973, the Dutch town of Tiel stopped fluoridation. Researchers
counted drilled, missing, and filled tooth surfaces (DMFS) of Tiel’s 15-year olds, then collected identical data from never-fluoridated Culemborg. DMFS initially increased in Tiel then dipped to 11% of baseline from 1968/69 to 1987/88 while never-fluoridated Culemborg’s 15-year-olds had 72% less cavities over the same period, reports Caries Research. (6)
A Canadian government report (7) shows similar negative results and
offers a reason. Fluoridation was launched in the 1940’s when dentists believed fluoride’s beneficial effects were achieved internally, through the bloodstream then absorbed inside the teeth. The Canadians report that “this effect is likely to be minor… The evidence for a post-eruptive (topical) effect,… is much stronger.”
Therefore, swallowing fluoride doesn’t reduce tooth decay but does
cause dental fluorosis – white spotted, yellow or brown stained and sometimes pitted teeth.
Poughkeepsie NY stopped fluoridation in 2008. Yet, third-graders cavity rates declined steadily – 61% in 2013; 51% in June 2014; 45% in October 2014; and 31% in 2015, according to NYU researchers.
According to the Americn Dental Association (ADA) “Over time, dental decay can be expected to
increase if water fluoridation in a community is discontinued, even if
topical products such as fluoride toothpaste and fluorde rinses are widely used.” (10)
Science proves the ADA is wrong about the claimed benefits of
water fluoridation and they are wrong about the safety of water
fluoridation, too.
Other US government studies and statistics support the findings of
these six studies and the Canadian government report. For example, children in fluoridated-since-1945 Newburgh, New York, have no less tooth decay but significantly more dental fluorosis than children from never-fluoridated Kingston, New York, according to Community Dentistry and Oral Epidemiology June 1999. New York State Communities which have stopped or rejected fluoridation are: Suffolk, Nassau & Rockland counties, Elba, Naples, Levittown, Canton, Corning, Johnstown, Oneida, Carle Place, Beacon, Poughkeepsie, Riverhead, Rockville Center, Central Bridge Water District, Homer, Ithaca, Rouses Point, Pulaski, Romulus, Amsterdam, Walden, Glens Falls, Manhasset and Wilton Water and Sewer Authority, Yorktown and Somers. NYS Dept of Health statistics show there is no correlation between the fluoridation rate of a county and tooth decay rates or to fewer dental-related hospital ER visits for toddlers
