Study Advises Lethal Levels of
Fluoride in Toothpaste For Children
Researchers from the Cochrane
Oral Health Group are recommending that parent use toothpastes
with lethal levels of fluoride for their children.
The report suggests parents should use toothpastes that contain
fluoride with a minimum concentration of 1,000 parts per million,
a dosage which is 250 times higher than what the Environmental Protection
Agency (EPA) states is the upper limit for humans. Even more concerning
is the author's claims that fluoridated toothpaste will prevent
tooth decay in children.
The same authors were previously responsible for a very flawed
and criticized study that showed a false association between fluoride
toothpastes and a reduction of dental decay compared to non-fluoride
products. The study was shown to be biased with non-supported
conclusions and conflicts of interest.
In case your wondering, funding sources for such studies at the
School of Dentistry, The University of Manchester come from the
toothpaste industry. Actually, the British Dental Association
has always received money from the toothpaste industry for endorsing
fluoride-based products. The British Dental Association also provides
financial support to the University of Manchester for many dental
practices at the School of Dentistry. Get the picture?
There is unequivocally no safe amount of fluoride (whether sodium
fluoride or hydrofluoric acid) that is safe for your child. Sodium
fluoride is a very toxic chemical, acting as an enzyme poison,
direct irritant and calcium inactivator. It reacts with growing
tooth enamel and with bones to produce irreversible damage.
Austrian researchers proved in the 1970s that as little as 1 ppm
fluoride concentration can disrupt DNA repair enzymes by 50%.
Fluoride prematurely ages the body, mainly by distortion of enzyme
Dr. Yiamouyiannis (former science director of the National Health
Federation) cited a 1990 study of 541,000 cases of osteoporosis
that found a definite connection between hip fractures in women
over 65 and fluoride levels.
In JAMA 1994, extremely low levels of water fluoridation 0.1 ppm
were found to produce a statistically significant increase in
According to the National Research Council (NRC), fluoride can
damage the brain. Animal studies conducted in the 1990s by EPA
scientists found dementia-like effects at the same concentration
(1 ppm) used to fluoridate water, while human studies have found
adverse effects on IQ at levels as low as 0.9 ppm among children
with nutrient deficiencies, and 1.8 ppm among children with adequate
According to the NRC, fluoride can diminish bone strength and
increase the risk for bone fracture. While the NRC was unable
to determine what level of fluoride is safe for bones, it noted
that the best available information suggests that fracture risk
may be increased at levels as low 1.5 ppm, which is only slightly
higher than the concentration (0.7-1.2 ppm) added to water for
Fluoride was found to be an equivocal carcinogen by the National
Cancer Institute Toxicological Program and Food and Drug Administration
(FDA) scientists reported a close correlation between decreasing
total fertility rates in women between ages of 10 and 49, and
increasing fluoride levels.
Campaigners and parents are increasingly angry that the risks
are not better publicised. In America, they point out, there is
a mandatory warning on every tube of fluoridated toothpaste: In
case of accidental ingestion, seek professional assistance or
contact a poison centre immediately. Why are British consumers
not given this information? Tony Lees, from Herefordshire, a dentist
for 40 years, believes that fluoride should be banned from toothpastes
and water. The marginal benefit it displays for teeth does not
outweigh its general dangers, he says.
In the scale of toxicity, fluorides fall between arsenic
and lead, he says. Dental fluorosis is not just a
cosmetic problem, but the visible sign of chronic fluoride poisoning,
and children are more vulnerable than adults.
Anyone overdosing on fluoride, he says, is in danger of developing
chronic skeletal fluorosis, which can weaken bones and cause arthritis.
