The Big
Lie: Fluoridation Helps the Poor
By Paul Connett, PhD
Time
and time again, promoters of fluoridation - from the US Surgeon
General down to the local dentist - have told an unsuspecting public
that the reason we have to fluoridate public water supplies is because
it is an "equitable" thing to do. We are told that it helps all
people, regardless of income, and provides much needed "dental care"
to the poor.
This argument is, of course, very powerful emotionally, as most people
want to do what they can to help the poor, particularly children. It
is, however, another example of the "Big Lie".
Lack of Dental Care
Whether
intended or not, for over 50 years fluoridation has served to distract
attention from the fact that the US, despite its enormous wealth,
provides very poor dental care to families of low income. Today,
roughly 80% of US dentists refuse to treat children on Medicaid
because Medicaid's compensation is too low.
One
mother of a Medcaid insured child recently told a group of researchers
from the
University of North Carolina :
"I could not get a dentist to take Medicaid. I got the
book out, the telephone book, and I went through about 10-15
dentists, and no one wanted to take Medicaid. I just gave up."
She is
not alone. The University of North Carolina researchers found that
Medicaid-eligible residents in 40 North Carolina counties have no
private dentist available to them.
The Quick "Fix"
To
remedy this situation, US health departments, instead of calling for
more investment in Medicaid, all too frequently seek the cheap and
easy, albeit illusionary, "fix" of water fluoridation. In such
campaigns, the challenge of finding the much-needed government funds
for strengthening Medicaid is usually bypassed and ignored.
This is, of course, probably one of the attractions of water
fluoridation - no difficult budget decisions - simply add an
inexpensive chemical (inexpensive because it's a hazardous industrial
waste product) to the water, and presto - the poor can enjoy the
dental care they wouldn’t otherwise receive.
In a sense, water fluoridation has become a de facto substitute for
dental insurance. Perhaps this is one of the reasons why western
Europe hasn't felt as compelled as the US to fluoridate their water -
because most of these nations have universal health insurance. As a
result, poor children do not have the same kind of difficulty finding
dentists who will treat them.
Of course, just because fluoridation is cheaper and easier for
government, doesn't necessarily mean that it is an effective
substitute for dental insurance. Indeed, there would be a good
discussion to be had, were fluoridation a safe and effective means of
reducing dental decay among the poor.
Unfortunately, however, that is not the case...
As a mounting body of evidence now indicates, fluoridation does not
reduce inequalities in dental health. Such was the conclusion of
the recent systematic review of fluoridation, published in the British
Medical Journal (the "York Review") and commissioned by the British
Government. According to
Dr.
Trevor Sheldon, the Chair of the York Review's advisory board, in
a letter sent to the House of Lords:
"There was little evidence to show that water fluoridation
has reduced social inequalities in dental health."
The US Experience
Perhaps
nothing illustrates Dr. Sheldon’s point more clearly than the
experience of poor urban areas in the US. Despite the fact that the
vast majority of urban areas in the US have been fluoridated for
decades, dental decay is rampant. The US Surgeon General recently
described the level of decay typically found in such areas as a
"silent epidemic" and an "oral health crisis."
Now, if fluoridation was an effective cure for poverty-related dental
decay, why is it that the nation's highest level of dental decay is
commonly found in the nations' inner cities, the vast majority of
which are fluoridated?
Take, for instance, the situation in Boston.
In 1999, the Boston Globe ran a
front page story detailing the oral health crisis among Boston's
poor. According to the Globe:
"With a study estimating that the number of untreated cavities
among Boston students greatly exceeds the national average, public
health officials are about to launch an offensive against what
they say is a growing dental crisis in the city."
As the
article points out, Boston has been
fluoridated since 1978.
And Boston's situation is by no means unique.
In his book Savage Inequalities, Jonathan Kozel notes
the oral health problems he has observed in the Bronx (a borough of
New York City).
"Bleeding gums, impacted teeth and rotting teeth are routine
matters for the children I have interviewed in the South Bronx.
Children get used to feeling constant pain. They go to sleep with
it. They go to school with it. Sometimes their teachers are
alarmed and try to get them to a clinic. But it's all so slow and
heavily encumbered with red tape and waiting lists and missing,
lost or canceled welfare cards, that dental care is often long
delayed. Children live for months with pain that grown-ups would
find unendurable...Many teachers in the urban schools have seen
this. It is almost commonplace."
The Bronx
has been fluoridated since the 1960s. A recent study published in the
journal Pediatric Dentistry compliments Kozel's observations.
According to the study, children from poor areas in New York City have
much higher rates of dental decay than the national average. The study
also notes that just 10% of the cavities among these children had ever
been filled by a dentist.
Nutritional Status and Fluoride Toxicity
It
would be bad enough, of course, if fluoridation were simply an
ineffective policy that diverted time and attention away from the
efforts and policies that would actually work.
But it
doesn't just stop there.
Adding
insult to injury, it is precisely the poor who are often most
susceptible to the toxic effects of fluoride.
As
noted in
a report by the National Research Council of Canada, fluoride
increases the body's metabolic requirement of certain nutrients. In
other words, the more fluoride one consumes, the more essential
nutrients (e.g., calcium, magnesium, vitamin C) the body will need in
order to stay healthy.
As a consequence, those with deficient nutritional status (which is
often the case with poor children) have less inborn-defense against
fluoride's toxic effects.
The most tangible example of this disparity can be witnessed in India,
China, and other poorer nations, where just slightly elevated levels
of fluoride in the water (e.g., 2 to 3 parts per million) cause a
whole array of health problems, the most prominent being a severe
arthritic bone disorder known as skeletal fluorosis (for
more information see
http://www.fluoridealert.org/s-fluorosis.htm ).
The
importance of nutrition in influencing fluoride's toxicity may
actually be one of the factors explaining why a couple of recent
studies have noted that African-Americans have higher levels of
dental fluorosis than Caucasians.
Dental fluorosis , a defect of the tooth
enamel that causes white and/or brown spots on the teeth, is one of
the first symptoms of excessive exposure to fluoride.
Incidentally, dental fluorosis is now at near epidemic proportions in
the US. The largest US government survey looking into the matter
recently noted that roughly one-third of children living in
fluoridated areas have dental fluorosis on at least 2 teeth. The
British government review, noted above, reckoned that approximately
48% of children living in fluoridated areas develop some form of
dental fluorosis, with roughly 12% developing fluorosis of great
enough severity to cause significant esthetic concern.
What is Causing Tooth Decay in the Inner Cities?
Lastly, let’s be clear about what is, and what is not, the cause of
tooth decay among the poor.
What is NOT the cause of tooth decay among the poor is lack of
fluoride. Despite some claims to the contrary, fluoride is not an
essential nutrient, and is not needed for the development of healthy
teeth. As stated recently by the Centers for Disease Control:
"The prevalence of dental caries in a population is not inversely
related to the concentration of fluoride in enamel, and a higher
concentration of enamel fluoride is not necessarily more
efficacious in preventing dental caries."
What is the cause of tooth decay among the poor is a bit more
complex, but basically boils down to two basic issues:
-
inadequate diets (too many "empty" calories — plenty of
sugar but devoid of nutrients)
-
inadequate dental care (lack of funds to spend on private
dental fees coupled with the absence of a functioning Medicaid
system).
In sum,
"dental equity" will not come with the lazy "magic bullet" of
fluoridation, but rather will require the much more demanding measures
of improving education, improving diet, providing free dental clinics
to serve those on Medicaid, and providing free toothbrushes and
possibly toothpaste to children in school.
In
short, if you truly care about poor children, don't give them poison -
give them genuine care.
