CDC Grand Rounds Beyond the Data: Community Water Fluoridation

Articles Blog


I’m Doctor John Iskander, welcome to CDC’s
Beyond the Data. I’m here today with
Dr. Barbara Gooch to discuss community
water fluoridation. Barbara could you for our
audience orient us generally at first to what we
mean by fluoridation or community water fluoridation? Community water fluoridation
is the adjustment of the fluoride content
of drinking water for the prevention
of tooth decay. Overall most water contains
fluoride that is generally at levels too low to
prevent tooth decay. So, after both public health and clinical research done
during most of the 20th century, we learned that at about
one part per million or one milligram per liter
of fluoride in water carries in communities, carries in
communities, that added fluoride to their water to that
level had about a 50 to 60 per cent reduction
in tooth decay. Remember at the time that community water
fluoridation was first introduced beginning in the
1940’s, that was the main source of fluoride, the water supply. So one essential benefit
that you’ve just talked about is prevention
of tooth decay. Gooch: Exactly. Are there other, for
example, economic benefits that we receive from
water fluoridation? Well yes, there certainly
has been, has been, an economic analysis, or
have been economic analysis. And these generally are
going to look at the cost of implementing a water
fluoridation program and the cost of the dental
treatment that’s prevented by instituting such a program. And these have generally found that community water
fluoridation is not only cost effective but also saves costs. One published estimate is
that for every dollar spent on community water fluoridation
programs $38 are saved in dental treatment
costs annually. What have we learned over the
years about adverse effects that might be associated with
community water fluoridation? That’s a very good question,
because we do get a lot of inquiries about
adverse effects. And multiple reviews by panels
of scientist over the years and also public health
professionals have assured that not only is community
water fluoridation beneficial but it’s safe. We’ve had several recent
reviews and those have concluded that the only, perhaps
termed “unwanted” effect, of fluoride in water
at the levels used for community water fluoridation
would be dental fluorosis. And let me just take a minute to explain what dental
fluorosis is. Dental fluorosis is a
change in the appearance of the tooth enamel,
so it’s a change in the appearance of
the tooth surface. In the United States, most dental fluorosis
is very mild, or mild. It’s barely detectable
to most individuals. It appears as just
white spots or flecks and generally it is detectable
by your dental professional. So, we, again we have a
public health intervention which is cost beneficial-
Gooch: Mm. Hmm. — has no evidence of
serious adverse health effects. People may be wondering though, compared to when fluoride
was originally instituted in water supplies, we now have
other sources of fluoride, what should people
know about fluoridation in the modern environment where there is fluoride
from other sources? Well, there are other
sources of fluoride that have become available since community water
fluoridation was introduced in the US. And these of course
are commonly known, fluoride toothpaste is used
daily by most persons in the US, fluoride mouth rinse
is in supplements. But, the available
data indicates that there is still
an additional benefit from drinking fluoridated
tap water. The most recent data indicates that you have an additional
benefit of about a 25% reduction in tooth decay from
community water fluoridation. Very good information. For people in our audience who want more information
what’s a reliable source for them to consult? Well, I would turn
to the CDC’s website, that’s CDC.gov/oralhealth and you will find additional
information on fluoridation and other oral health topics. Thank you very much Barbara. Please join us next month for another addition
of Beyond the Data.

  1. The Community Water Fluoridation, The doubt virus? Looking forward to analyze all of the CDC data. The National Center for Chronic Disease Prevention and Health Promotion. The simplest answer to the question is that there is trillions of dollars involved.

  2. This is medication without consent. Almost everyone has access to fluoridated toothpaste in the United States. Putting in fluoride in drinking water that we SWALLOW is absolutely ridiculous. We don’t swallow toothpaste.

  3. These people come off as snakes.. I'm going to research into Fluoride a little more

    I became concerned after seeing it on so many toothpaste brands especially childrens…

  4. Using a Water Distiller to Get Rid of Fluoride
    One of the best ways to remove fluoride from your water is to invest in a water distiller. Distilled water never contains fluoride as the distillation process effectively removes fluoride and a host of other contaminants that are harmful to your health. In fact, water distillation is so effective that the process is capable of removing just about anything from water.
    Creating distilled water through the distillation process is simple and easy. All you have to do is boil the water that you wish to purify and collect the water vapor in the form of steam. This steam, once collected, will yield fresh, clean drinking water that is fluoride free. Decreasing the amount of fluoride that you consume is a good step to ensuring good dental health and a healthy lifestyle, so if you want to start investing in your future, you can start by investing in a good water distiller.
