Drinking water with fluoride is neither safe nor effective.
Although, some have called artificial fluoridation controversial, I find that it can be a very easy subjectto understand. It is as easy as 1, 2, 3. http://www.youtube.com/watch?v=l84eU7oQatI
First, does fluoride work to reduce tooth decay if swallowed? No, it does not.1After claiming for more than 50 years that the effects of fluoride on tooth decay were systemic, virtually
all of the fluoridation proponents have now reluctantly acknowledged that the only measurable dental
effects are topical.2
Like sun block, its topical. You shouldnt drink it.
Read the FDAs Warning on fluoridated toothpaste:
KEEP OUT OF REACH OF CHILDREN UNDER6 YEARS OF AGE. IN CASE OF ACCIDENTAL INGESTION,
SEEK PROFESSIONAL ASSISTANCE OR CONTACT A POISON CONTROL CENTER IMMEDIATELY.
Second, is it safe for babies or the handicapped? No, it is not.34
Any doctor would be guilty of gross malpractice if they prescribed the same dose of fluoride that an
infant receives from drinking formula made with fluoridated tap water about 0.25 mg/kg. NationalAcademy of ScienceReview of Fluoride noted that an iodine deficient child is injured by as little as 0.01
mg/kg. They listed dental fluorosis, bone fractures, and endocrine disruption as adverse health effects.5 2
out of 3 children raised in a fluoridated community already have at least some degree of dental
fluorosis.6http://www.youtube.com/watch?v=KgifD0TPKCY&feature=channel
If fluoride is not safe for babies, are other subsets of the population unusually vulnerable to the toxiceffects of fluoride? Certainly!
The U. S. Center for Disease Control Agency for Toxic Substances and Disease
Registry states that, These [susceptible] populations include the elderly, people withdeficiencies of calcium, magnesium, and/or vitamin C, and people with
cardiovascular and kidney problems.7

Third, is ingested fluoride for the purpose of reducing tooth decay FDA approved?
No, it is not.8 (Congressional Hearings 2001 www.keepers-of-the-well.org)
The U. S. Food and Drug Administration has never approved any fluoride containing substance intended
to be ingested to reduce tooth decay. In fact, by 1975 they had rejected 35 new drug applications forfluoride vitamins and supplements stating that, There is no substantial evidence of effectiveness as
prescribed or labeled. 9
It is just as simple as 1, 2, 3.
1) Dental benefit, if any, is only TOPICAL and not SYSTEMIC2) The ADA agrees that tap water formula is NOT safe for small babies.3) NOT FDA Approved as safe or effective because that is not how it works.
The really bad news is they dont use fluoride but rather arsenic, lead and mercury contaminatedhydrofluosilicic acid which is raw untreated hazardous waste from the pollution scrubber systems of the
phosphate fertilizer mines of China, Mexico, Japan and the United States.
In my opinion, the water should be safe for us all to drink. The public agrees. Fluoridation steals dentalcare dollars from children in a fake prevention program that only benefits industry with hydrofluosilicic
acid hazardous waste.
And besides, the state legislature AB733 specifically restricted its compelling legislation to onlysituations where rate-payers and tax payer funds are not required. The Metropolitan Water District
(MET) is not required to fluoridate nor are many of their member water agencies. MET recentlyannounced a 40% increase in their water rates.

The first graph illustrates the expected range of consumption of community water (public tap
water) for various age groups, in quantities of milliliters per day (mL per day). The ranges
include only people who actually consume tap water. Note that some people consumesubstantially more tap water than the usual range. This information is from an EPA reportpublished in 2004.
The total consumption of community water shown here is not to be confused with total fluid
consumption or total water consumption. It does not include well water, bottled water, or

some infants reaching more than 250 mL per kg per day.
In general, the people with the highest tap water intakes include babies fed formula made with
tap water, people with certain medical conditions (e.g., diabetes insipidus, diabetes mellitus) or
taking certain medications (e.g., lithium), people in unairconditioned residences in hot climates,people who work outside in hot climates or do heavy physical labor, and athletes.

The third graph shows estimated fluoride intakes for each age group (mg of fluoride per kg of
body weight per day), assuming the range of tap water intakes shown in Slide 2 and a fluoride
concentration in the tap water of 0.8 ppm (0.8 mg fluoride per liter of water). Also shown is
EPAs reference dose, which is defined as an estimate of a daily oral exposure to the human
population (including sensitive subgroups) that is likely to be without an appreciable risk of
deleterious effects during a lifetime. For fluoride, the reference dose is 0.06 mg per kg per day.As seen in the graph, many infants have a fluoride intake just from tap water that exceeds EPAsreference dose for fluoride. The children (ages 1-10) with the highest water consumption also
exceed EPAs reference dose. Older children (youth) and adults with the highest water
consumption are very close to EPAs reference dose.
Note that this graph shows estimated fluoride intakes only from tap water. These estimates do
not include fluoride intakes from other sources, such as commercial beverages (which are often
made with fluoridated tap water), toothpaste, tea, or food. When these other sources of fluoride
intake are included, total fluoride intakes for many members of all age groups exceed EPAsreference dose.

The final graph shows the estimated fluoride intakes from tap water from Slide 3, plus estimates
of the no-effect levels for various adverse health effects. These no-effect levels representfluoride intakes at or below which most people are not expected to experience any harmful
effects. Note that these are estimates based on average exposures of study populations; theseestimates do not include any margin of safety, and they might not be protective for allindividuals. Intakes above these levels cannot be considered safe.
Note also that most of these no-effect levels are lower than EPAs reference dose for fluoride.
In other words, EPAs reference dose is not protective for most of these health endpoints.
Note also that most of these no-effect levels are exceeded by many members of the population,of all ages, just from fluoride at 0.8 ppm in community drinking water. When other fluoride
sources are included, even more people are expected to exceed the no-effect levels. In order tobe safe for all members of the population, fluoride intakes for all people must be kept below
the lowest no-effect levels, with all sources of fluoride intake are included, and with anadequate margin of safety.
This list of adverse health effects does not include cancer. A carcinogenic (cancer-causing)
effect of fluoride cannot be ruled out from the available data, and at the very least, a cancer-promoting effect is likely. For carcinogenic substances, the risk of cancer increases with the
amount of exposure, such that even a very low exposure carries with it some cancer risk.

In conclusion, I would like to quote from the Director of Laboratories, Department of Water
Supply, Gas and Electric, of the City of New York, from a presentation made in 1956 but stillrelevant today:
The continued promotion of water supply fluoridation in [the] face of mounting
adverse evidence an criticism requires some evaluation. It seems that theproponents hit upon an idea years ago which appealed to them, and which they
felt was sound. As their claims for safety were progressively discredited, rather
than acknowledge this, they persisted in condoning such evidence. At the sametime they were lending their prestige to such equivocation. Certainly the
proponents of fluoridation are not intent upon poisoning or harming anyone,
however, the dilemma of prestige is a very difficult matter to resolve.
The proponents have tried to demonstrate various factors of safety which are
patently nave. . . . It has been customary to consider a minimal factor of safety of
not less than 10 for substances which may be admitted to water supplies. This
would mean that ten times the amount of the proposed substance when present inthe water supply would be definitely without harm to human or beast. It is
obvious from the knowledge of fluoride toxicity that such factor of safety cannotbe established when fluoride is added to the public water supply at the level
recommended by the proponents of fluoridation. In view of the fact that the range
of water consumption may vary over a ratio of 20 to 1 the insistence upon a factorof safety of 10 is exceedingly moderate.
It must be concluded that the fluoridation of public water supplies is a hazardous
procedure, people are bound to get hurt, it remains to find out how many andwhen. I do not believe the water supply fraternity is interested in demonstrating
this with wholesale experimentation on populations.

Board of Supervisors
County of Santa Cruz
701 Ocean StreetSanta Cruz, CA 95060RE: Drinking Water FluoridationMarch 1, 1998Dear Supervisors,I am David Kennedy, DDS. I am a preventive dentist. I have practiced dentistry in San Diego for morethan 20 years. My father and grandfather before me were also dentists. I served on the board of the San Diego Better Business Bureau for over 10 years, and have been amember of the Centre City Optimist Club for 20 years as well.I have been a member of the San Diego County Dental Society for over 20 years, and for three yearselected to the Board of Directors. I have participated on numerous committees including. Senior Care,Speakers Bureau, Political Action Committee, and the Council on Dental Care.In 1974 Eddy Oriole and I planned and built the Chicano Children's Dental Health Clinic at 1809 NationalAvenue. I care about children's dental health.I am immediate Past President of International Academy of Oral Medicine and Toxicology, the author of abook on preventive dental health entitled How to Save Your Teeth, and a nationally and internationallyrecognized lecturer on toxicology and restorative dentistry.I am intensely interested in the welfare of my patients and the community at large. Although I am a member of the San Diego County Dental Society (SDCDS), The California Dental
Association (CDA) and the American Dental Association (ADA), I must begin my statement by expressing
my opposition to these organization's stances concerning the safety of fluoride and further clarify what anendorsement by any of these organizations represents.1) CDA and ADA perform no research of their own.2) These trade associations have successfully argued in court that they assume no legal liability for anyharm that may result from their recommendations.3) Dental organizations are not responsible for studying adverse systemic effects of water fluoridation.
These issues are appropriately studied by medical researchers, epidemiologists and toxicologists.
4) CDA and ADA have never provided their members any large scale blinded studies which prove thatfluoridation reduces tooth decay. An expert for the ADA testified in court that she was not aware of any
blinded animal or broad based blinded human epidemiological studies that has ever found a reduction intooth decay from drinking water with one part per million fluoride.5) CDA and ADA have never polled their membership for their knowledge or opinion of water fluoridation.The two following examples clearly illustrate the depth and reliability of dentist's understanding of thiscontroversial issue.

A) Despite the local dental society's recommendation of water fluoridation, my conversation with the
President of the San Diego Dental Society, Dr. Joel Berick, revealed that he was completely unaware ofeven the existence of numerous studies linking water fluoridation to hip fracture.B) An elderly dentist from Chula Vista took umbrage with my position opposing water fluoridation. He
claimed that, over the last 50 years in his practice, he had personally witnessed the tremendous benefit ofwater fluoridation in Chula Vista. When I pointed out that Chula Vista was a nonfluoridated community, he
appeared disoriented and mumbled, "It had to be the fluoride. Tooth decay is not nearly as prevalent aswhen I began to practice 50 years ago." The above summary is not intended to criticize the dental society, but rather to place the dental tradeorganizations endorsements in their proper perspective.Increasing the fluoride intake of a patient without regard to established risk factors such as age, kidneyfunction, weight, physical condition, water consumption, total fluoride intake, and mitigating dietarycalcium is medical negligence. Although the courts have ruled that the state has the power to do so under
police powers. mandating fluoridation for 25 Million Californians or the entire city of Mountain View is noless negligent.
Dental FluorosisThe first visible sign of this negligence will be a doubling in dental fluorosis. The cells that produce the
collagen matrix, which forms enamel, are poisoned to the point that they can no longer produce
opalescent pearl-like enamel. Fluorotic enamel is irregular in texture, porous, chalky white to brown incolor, and brittle. In severe cases, the enamel forms incompletely and corners easily break off the teeth.All of the organizations promoting water fluoridation agree that dental fluorosis, which is the first visiblesign of systemic poisoning, increases with water fluoride levels. The Legislative Office of Budget
Management acknowledges that drinking water fluoridation would increase disfiguring dental fluorosis, but
since treatment of this disease is not covered for children on welfare, calculated that there would be noadditional. cost to the state. Clearly they are not considering the enormous legal liability for physical andpsychological damage which accompany this disfiguring disease. The fact that the state will not spend money to correct this defect does not alter the basic truth thatfluorosis will have to be treated if the child is to be happy in our image conscious society.Let's be clear about what children will be adversely affected. Bottle fed babies are most likely to develop
dental fluorosis. Mothers milk has virtually no fluoride present. Those children who are deficient in intakeof protein, calcium, magnesium, phosphorous, and Vitamin C are especially vulnerable to fluoridepoisoning. The accumulation of fluoride is greatly increased if the person has impaired kidney function. In
short, the weakest members of our society, the undernourished, the underfed, the very children that
fluoridation was to allegedly benefit. In some poorer communities as much as 80% of the children havefluorosis[1].The correction of this permanent disfigurement involves crowns, laminates, bonding, and bleaching. Thephysical, psychological, emotional, and financial costs of the repeated trauma necessary to correct this
condition far exceeds any projected benefit that fluoridation can possibly produce. This is truly a case
where the treatment is worse than the problem.The incidence of dental fluorosis has steadily increased since the introduction of fluoride to the drinkingwater in 1945. Since the introduction of fluoride containing toothpaste the amount of fluorosis hasdramatically risen[2]. Fluoride tablets which deliver in prescription form the amount of fluoride alleged to
be beneficial for tooth decay, reduction cause dental fluorosis in 64% of the children (Pebbles 1974).These same tablets if swallowed provide no protection against decay. If they are chewed and dissolved inthe mouth, they do appear to reduce decay[3]. The effect is topical[4].
Hip FractureFluoride has been tested on humans for the purpose of treating osteoporosis. The theory was that fluoride
would strengthen bones. What the researchers found was that it did increase bone mass; however, the
8/2/2019 Kennedy, DDS Presentations to Officials
10/12
bone was much more brittle -- leading to a dramatic increase in hip fracture[5]. Numerous studies havelinked long term consumption of fluoridated water to increased risk of hip fracture.[6]This is not a small matter, it is about life and death. The surgical cost of repairing a hip fracture is
$35,000. 25% of the victims die in the first 30 days. Only 11% of the victims ever return to independent
living. 100% of the victims are debilitated and few, if any, of the elderly ever regain their former ability towalk normally. The research clearly shows that water Fluoridation increases the number of people who willsuffer this devastating injury.Nine of thirteen studies show a correlation between hip fracture and fluoridation, including four published
in the Journal of the American Medical Association in the last five years. In matters as serious as thehealth of our nation, no risk is acceptable if it is avoidable.
CancerResearch has shown in numerous studies that fluoride is a mutagen (genetic damage), a carcinogen
(cancer causing), and cancer promoting in laboratory cell studies, animals, and humans. In 1990 theCongress-ordered National Toxicological Program (NTP) found bone cancers in male rats.The test animals, in the words of the board certified pathologists, "were awash with disease." T he highdose animals had kidney failure and cancers of their lips, cheeks, throats, livers, and bones. The highest
rates of cancer were found in the highest dose animals. The lucky rats and mice that drank the distilledfluoride free water had no significant disease. When the actual data indicated a causal relationshipbetween fluoride and bone cancer the NTP down-graded the results to "equivocal."Dr. William Marcus, former senior science advisor at the office of drinking water Environmental ProtectionAgency (EPA), concluded that the NTP studies proved fluoride was a carcinogen[7]. In July 1997 the
National Federation of Federal Employees. the Union representing all of the scientists, toxicologists and
statisticians at EPA headquarters, also stated that "Our members review of the body of evidence over thelast eleven years, including animal and human epidemiological studies, indicate a causal link betweenfluoride/fluoridation and cancer, genetic damage, neurological impairment, and bone pathology. Of
particular concern are recent epidemiological studies linking fluoride exposure to lower 1.0. in children.[8]Political protection for fluoride is not new. The Spin Doctors of fluoridation routinely minimize the peer-
reviewed documented scientific research by setting up biased review committees, which then publish theirown opinion claiming that fluoridation is safe, without regard to the original findings. The US Public Health
Service has been accused of scientific fraud by the National Federation of Federal Employees over thecover-up of the cancer/fluoride link.After the NJ Department of Health documented a dramatic increase in bone cancers in young men who
resided in their fluoridated cities, New Jersey Assemblyman John V. Kelly asked the Food and DrugAdministration (FDA) for the evidence they relied upon in approving prescription fluoride drops andtablets.The FDA responded that no application for approval, or studies of safety or effectiveness, had ever beensubmitted and that they were not in possession of any such evidence. Ask yourself for another example of
a prescription drug on the United States market (30 plus years) for which no FDA Application has everbeen submitted.When pressured as to why he did not remove the drops and tablets from the market Frank R. Fazzari,
Chief of Prescription Drug Compliance reportedly expressed concern for his position and recommendedAssemblyman Kelly sue him in order to have a Federal Judge make him comply with congressional law. The new Food and Drug required warning should provide some clarification as to the safety of fluoride.The FDA now requires all toothpaste containing fluoride to have the following warning attached,
"WARNING: Keep out of reach of children under 6 years of age. In case of accidental ingestion, seek
professional assistance or contact a Poison Control Center immediately." The amount to be used inbrushing is a pea sized amount or about 1 milligram. One liter of water in a fluoridated community will
contain one milligram.

Tooth Decay Costs SavingsAll of the recent large scale studies have found no relationship to tooth decay and water fluoride levels.Earlier studies that are often cited by fluoridation promoters are transparently flawed. The examiners were
not standardized or blinded. There are no randomized controlled blinded studies of animals or humans
that have ever found a reduction in decay from ingesting fluoride. On the contrary, all of the recent large-scale studies have failed to show any significant reduction. Studies of fluoride have confirmed that the effect it has on tooth decay reduction is not systemic. The
effect is not produced by swallowing the toxic substance, but is in fact a topical effect upon the bacteria
that live in the mouth and cause tooth decay. It poisons them. The design of the experiment leaves littledoubt -as to the results. Cavity-prone rats were given fluoride in two ways. One group got fluoride in themouth from a time release tablet bonded to the outer surface of the tooth. The other group got the same
amount administered in a slow pump under the skin. The oral dose of fluoride produced some reduction in
decay over controls, but the systemic exposure did not reduce tooth decay at all. However, the poisonousnature of fluoride does not change when ingested.Animals fed sugar-water and fluoride fare no better in terms of tooth decay than animals fed sugar-wateralone. Human tooth decay is linked to diet, sugar intake, tooth brushing technique, hours of sunlight,
parental education, and family income. These variables must be considered in order to produce accurateresults.In the largest study of tooth decay in America, there was no significant difference in the decay rates of
39,000 fluoridated, partially fluoridated, and non fluoridated children, ages 5 to 17, surveyed in that 84city study. The decayed missing or filled rate in non-fluoridated Los Angeles was not significantly differentthan fluoridated San Francisco. In fact, the lowest decay rate was found in non-fluoridated Buhler, KS. Comparing the State of California 1994 non-weighted dental costs for the 14 largest counties reveals thatcounties 90% fluoridated spent on average $121.93 per eligible recipient for treatment of tooth decay,and counties with less than 10% fluoridation spent only $118.33 per eligible recipient.
Weighted 1995 California per Eligible Welfare Recipient Dental CostsCA Counties 90 -100 % Fluoridated $125.27
CA Counties 0.5- 10% Fluoridated $107.26With less than 17% of the state fluoridated, California children have fewer cavities than the nation as awhole. Where is the alleged proof of safety and effectiveness? Why are the costs of dental care higher influoridated areas?This public health fraud will result only in increased misery-- kidney disease, hip fractures, cancers and
even death to its many unfortunate victims. Not only will fluoridation not reduce the dental care costs, itwill exponentially increase the fluorotic damage to underprivileged children.Sincerely,David C.
