NYSCOF – When Fluoridation Ends – Cavities Drop

New York – — Cavity rates declined in several cities that stopped
water fluoridation, new studies report, contradicting American Dental
Association (ADA) predictions.

Fluoride added to about 2/3 of US public water supplies is supposed to
reduce tooth decay but these six studies from dental journals show it
hasn’t and, in fact, may have increased the likelihood of rotten

. “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

· 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.

According to the 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)

However, non-fluoridated Nassau County, NY, has lower tooth decay rates
than the state average despite that New York State is 73% fluoridated.

“Well, science proves the ADA is wrong about the claimed benefits of
water fluoridation and they are wrong about the safety of water
fluoridation, too” says lawyer Paul Beeber, President, New York State
Coalition Opposed to Fluoridation. “Studies have linked fluoridation
chemicals to increased blood lead levels, neurological defects, brittle
bones, thyroid dysfunction, cancer and more,” says Beeber.

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.

Hawaii and California, the least fluoridated US states (13.0% and
15.7%, respectively) also produce residents least likely to be
toothless, according to the Morbidity and Mortality Weekly Report. Yet
Kentucky and West Virginia, 100% and 82.1% fluoridated, have the most
toothless residents.

    Let it be known by researchers. The ADA does not have a patent on the testing of fluoride in saliva. Saliva is loaded with fluoride.
