A new study reports that children who drink typically-fluoridated tap water have higher blood-lead levels (BLL) than children, who drink bottled water, according to dental researchers Sanders and Slade (American Journal of Preventive Medicine, Nov 2017).
While this wonky study is flawed, several previous studies link fluoridation chemicals to higher BLL; others link blood-lead to more tooth decay.
We’re not sure if Sanders and Slade are protecting dentistry’s sacred cow, fluoride, instead of America’s children and future, when they oddly put tooth decay on the same level with brain damaging lead.
Without knowing the fluoride content of any of the water consumed by their test subjects, they imply that tap water drinkers have less tooth decay and the reason is the presumed fluoride content of tap water. They hint that parents might need to choose between damaging their children’s brains with lead or save their teeth with fluoride.
No! Cavities can be fixed but lead poisoning is irreversible.
Even low blood-lead-levels are linked to lower IQ, according to the CDC
The three artificial water fluoridation additives are fluorosilicic acid, sodium fluorosilicate (both silicofluorides) and sodium fluoride (CDC) All can contain contain lead when added to public water supplies.
Masters and Coplan (Neurotoxicology 2000) reported a link between fluoridation chemicals (silicofluorides) and children’s lead absorption.
A CDC study (Macek) attempted but failed to dispute Masters and Coplan’s findings. Macek’s research also revealed that fluorosilicic acid was associated with an elevated risk for high blood-lead-levels, according to the Fluoride Action Network (FAN). Macek decided the findings weren’t significant except among children living in houses of unknown age who had a 530% increased risk for high-blood-levels, reports FAN
A re-analysis of Macek’s data, after placing children exposed to fluorosilicic acid and sodium fluorosilicate in one group (silicofluorides) and all others in another, Coplan et al. found that the children exposed to silicofluoridated water had a significantly elevated risk of having high blood lead levels.
Coplan explained to this writer that, since silicofluorides don’t come apart totally in water, a breakdown product may enhance the uptake of lead into children’s blood – lead that’s already in the environment (not necessarily in the water). Sodium fluoride completely comes apart in water.
An Environmental Health Perspectives 2002 study, supports Masters and Coplan’s findings. Children in the silicofluoridated Boston area have more tooth decay and higher blood lead levels than children in non-fluoridated Farmington, Maine.
Lead is linked to more tooth decay
Several studies link blood lead levels, even low amounts, to higher rates of tooth decay. (BMC Oral Health Jan 2017; Caries Research 2015; Journal of the American Medical Association 1999 ; Journal of Clinical Pediatric Dentistry 2013 & 2017; Vojnosanit Pregled 2013 )
In fact, “Associations between childhood lead exposures and dental caries in children have been reported for over 30 years,” according to Science of the Total Environment(2007)
Children’s teeth with a high lead and high fluoride content had significantly more cavities than teeth with less lead and fluoride (Journal of Dental Research 1977).
Fluoride Can Increase the Uptake & Toxicity of Lead
Rats exposed to lead and sodium fluoride accumulates higher lead concentrations in their blood than rats only exposed to lead, according to NIH government researchers in 1976.
Lead intensifies fluoride’s teeth damaging effects causing a greater incidence and severity of dental fluorosis. (Leite 2011)
Exposure to lead exacerbates dental fluorosis. (Arch Oral Biology)
In fact, there’s some evidence that fluoride caues cavities.
“Despite significant financial, training, and program investments, US children’s caries experience and inequities continued to increase over the last 20 years.” ( American Journal of Public Health 2017). This after 72 years of fluoridation, reaching 2/3 of Americans, promising to substantially reduce tooth decay, especially in poor children.
The Journal of the American Dental Association (Dye 2017) reports,
65% of poor 6-8 year-olds and 12-15 year-olds have cavities in their primary and permanent teeth, respectively.
“The prevalence of pediatric caries in the United States has remained consistent for the past 3 decades,” reports Dye.
“… there has been little improvement in preventing caries initiation,” said Dye.
Perhaps Sanders and Slade are protecting organized dentistry or just can’t believe the obvious. Fluoride is harming America’s children and America’s future. Fluoridation must be halted right now!
It’s up to every individual to urge legislators and water departments to stop adding this unnecessary, health-robbing, ineffective and money-wasting chemical, fluoride, into your bodies via the water supply. If you don’t, nothing will change. It’s time to speak truth to power and see the dominoes fall just as the powerful predators are being taken down by courageous women in the workplace.
