Civil servants in fluoridated countries are behaving as if it is more important to protect the fluoridation program than it is to protect the health of their citizens!

News from the UK yesterday: “ News from the UK yesterday: “ Water fluoridation above a certain level is linked to 30 per cent higher than expected rate of underactive thyroid (hypothyroidism) in England, suggests research published online in the Journal of Epidemiology & Community Health. “ The researchers call for a rethink of public health policy to fluoridate the water supply in a bid to protect the nation’s tooth health.”
16
the UK study found a relatively strong and statistically significant effect, with General Practice (GP) areas being 62% more likely to have high rates of diagnosed hypothyroidism if their drinking water fluoride levels were above 0.7 ppm compared to areas with fluoride levels below 0.3ppm. This was after researchers had accounted for key confounders, which are other factors that influence hypothyroid rates.
17
This was after researchers had accounted for key confounders, which are other factors that influence hypothyroid rates. But Dr. David Crum of the the New Zealand Dental Assn is saying - "the research was flawed because fluoridated areas of Britain were also the areas with high iodine deficiency"

Part 1. Better ways of fighting tooth decay 1) Fluoridation is Unusual
20
The vast majority of countries do NOT fluoridate their water

Part 1. Better ways of fighting tooth decay 2) Fluoridation is Unnatural
24
Nature’s verdict: Nature’s verdict: The level of fluoride in mothers’ milk is EXTREMELY LOW The level of fluoride in mothers’ milk is EXTREMELY LOW 0.004 ppm 0.004 ppm (NRC, 2006, p. 40) (NRC, 2006, p. 40)
25
Mothers’ milk protects our babies from early exposure to fluoride F = 0.004 ppm
26
Water fluoridation removes nature’s protection F = 1.00 ppm 250 x level in mothers’ milk
27
A bottle-fed baby in a fluoridated community (0.7 – 1.2 ppm) is getting 175-300 times the fluoride dose that nature intended! A bottle-fed baby in a fluoridated community (0.7 – 1.2 ppm) is getting 175-300 times the fluoride dose that nature intended!
28
In other words by Nature’s standards In other words by Nature’s standards 1 ppm is not small it is HUGE!
29
Please Note: Life evolved from the sea where the level of fluoride is about 1.4 ppm, BUT not one single process in the body requires fluoride to function! Fluoride is NOT an essential nutrient
30
Please Note: Many biological processes and components are harmed by fluoride (enzymes, G-proteins etc)
31
Part 1. Better ways of fighting tooth decay 3) Fluoridation is Unethical
32
W e should NEVER use the public water supply to deliver ANY medical treatment W e should NEVER use the public water supply to deliver ANY medical treatment a) You can’t control the DOSE b) you can’t control who gets the treatment AND treatment AND c) it violates the individual’s right to informed consent to medication
33
Part 1. Better ways of fighting tooth decay 4) Fluoridation is Unnecessary
34
In 1999, the CDC Oral Health Division (the #1 promoter of fluoridation in the world) conceded that the predominant benefit of fluoride is TOPICAL not SYSTEMIC.
35
CDC, MMWR, 48(41); 933-940, Oct 22, 1999 “fluoride prevents dental caries predominantly after eruption of the tooth into the mouth, and its actions primarily are topical…” “fluoride prevents dental caries predominantly after eruption of the tooth into the mouth, and its actions primarily are topical…”
36
This admission by the CDC Oral Health Division should have ended fluoridation worldwide!
37
If fluoride works primarily on the outside of the tooth not from inside the body, Why swallow it and expose every tissue of the body to a toxic substance, when you can brush it on your teeth and spit it out? And why put it in the drinking water and force it on people who don’t want it?

Fluoride – but not necessarily water fluoridation – Damages the bone Lowers thyroid function Damages the brain
41
Since 2006 much more has been published on fluoride and the brain. Many animal and human studies indicate that fluoride is a potent neurotoxicant – www.FluorideALERT.org/issues /health/brain
42
30 out of 32 Animal Studies Have Found Fluoride Impairs Learning/Memory
43
IQ studies – the current tally 44 out of 51 studies have found an association between fairly modest exposure to fluoride and lowered IQ (China, India, Mexico and Iran ) 44 out of 51 studies have found an association between fairly modest exposure to fluoride and lowered IQ (China, India, Mexico and Iran )

More details on one of the IQ studies
53
Xiang et al. (2003 a,b) Compared IQ of children in two villages: Low Fluoride Village Average F in well water = 0.36 ppm (Range = 0.18 -0.76 ppm) High Fluoride Village Average F in well water = 2.5 ppm (Range 0.57 – 4.5 ppm) Controlled for lead exposure and iodine intake, and retrospectively for arsenic. Found a drop of 5-10 IQ points across the whole age range between the two villages
59
The lowest level that lowered IQ in Xiang study See group B, mean fluoride concentration = 1.53 ppm +/- 0.27 See group B, mean fluoride concentration = 1.53 ppm +/- 0.27 Some children had IQ lowered at 1.26 ppm Some children had IQ lowered at 1.26 ppm This leaves no adequate margin of safety to protect all children drinking water between 0.7 and 1.2 ppm. We usually use a safety factor of 10 to account for the wide range of sensitivity expect to any toxic substance in a large population.

The US EPA is in the process of determining a new MCLG (maximum contaminat level goal) for fluoride as recommended by the NRC in 2006. They say they are using SEVERE dental fluorosis as the most sensitive end point of fluoride’s toxicity. They say they are using SEVERE dental fluorosis as the most sensitive end point of fluoride’s toxicity. They claim that if they protect for this it will protect against damage to the bone and any other tissue. They claim that if they protect for this it will protect against damage to the bone and any other tissue.
69
To demonstrate that SEVERE DF is a more sensitive end point than lowered IQ they would have to show that ALL the children in the “High Fluoride” village in all the 40+ studies where IQ was lowered To demonstrate that SEVERE DF is a more sensitive end point than lowered IQ they would have to show that ALL the children in the “High Fluoride” village in all the 40+ studies where IQ was lowered had only SEVERE DF and not other milder categories had only SEVERE DF and not other milder categories

Part 1. Better ways of fighting tooth decay 6) Fluoridation is Ineffective
74
1) No RCT after 70 years!
75
RCT = randomized control trial, the gold standard of epidemiology testing of drugs
76
2) WHO data
77
According to WHO data tooth decay in 12-year-olds is coming down as fast in NF as F countries

3) The largest survey of tooth decay in the US
82
NIDR survey: Brunelle & Carlos (1990) They looked at 39,000 children in 84 communities. They looked at 39,000 children in 84 communities. In Table 6 Brunelle and Carlos compared tooth decay of children who had spent all their lives in a Fluoridated Community with those who had spent all their lives in a Non-Fluoridated one In Table 6 Brunelle and Carlos compared tooth decay of children who had spent all their lives in a Fluoridated Community with those who had spent all their lives in a Non-Fluoridated one

85
Brunelle and Carlos, 1990 Average difference (for 5 - 17 year olds) in DMFS = 0.6 tooth surfaces 3.4 DMFS NF 2.8 DMFS F
86
Not only was this saving very small (0.6 of one tooth surface) but it was not even shown to be statistically significant!
87
4) The most precise study of tooth decay in the US
88
Warren et al. (2009) (the “Iowa” study) examined the relationship between the amount of fluoride ingested by individual children (in mg/day) and their level of tooth decay
89
They found no clear relationship! The authors state: “These findings suggest that achieving a caries-free status may have relatively little to do with fluoride intake…” Warren et al., 2009 Warren et al., 2009
90
Part 1. Better ways of fighting tooth decay 7) There are better ways of fighting tooth decay in low-income families
91
A Better Strategy Most of the tooth decay today is concentrated in low-income families. We need to target those families with better dental services, better dental education and better diet. They have done this in Scotland
92
Scotland Instead of water fluoridation, the Scottish Government instigated its ChildSmile program. This involves: Instead of water fluoridation, the Scottish Government instigated its ChildSmile program. This involves: a) teaching toothbrushing at nursery-school a) teaching toothbrushing at nursery-school b) plus healthy snacks & drinks; b) plus healthy snacks & drinks; c) plus health, dental hygiene and diet advice to their families; c) plus health, dental hygiene and diet advice to their families; d) annual dental check-ups and treatment if required including fluoride varnish applications. d) annual dental check-ups and treatment if required including fluoride varnish applications.
93
Scotland The proportion of children aged 4–6 years without obvious dental decay has risen from 42% in 1996 to 67% in 2012. The proportion of children aged 4–6 years without obvious dental decay has risen from 42% in 1996 to 67% in 2012.

95
The message: The message: our kids need MORE BRUSHING! our kids need MORE BRUSHING! MORE FRUIT AND VEGETABLES! MORE FRUIT AND VEGETABLES! LESS SUGAR! LESS SUGAR! Less sugar means less tooth decay and less OBESITY Less sugar means less tooth decay and less OBESITY Less obesity means less diabetes and fewer heart attacks Less obesity means less diabetes and fewer heart attacks In other words education to promote less sugar consumption is a very good investment!

102
Make that 173, over the last few days we heard that Montello, Wisconsin; Boynton Beach, Florida and East Brunswick, New Jersey have voted to end fluoridation
103
1n Nov 2012, Queensland lifted mandatory requirement
104
In August 2014, the Israeli Minister of Health announced an end of fluoridation in Israel.
