    Impact of Fluoride on Neurological Development in Children

    “Fluoride seems to fit in with lead, mercury, and other poisons that cause chemical brain drain. . .” Based on the findings, the authors say that this risk should not be ignored, and that more research on fluoride’s impact on the developing brain is warranted.

    Water Fluoridation: A Critical Review of the Physiological Effects of Ingested Fluoride as a Public Health Intervention

    This paper reviews the human health effects of fluoride. The authors conclude that available evidence suggests that fluoride has a potential to cause major adverse human health problems, while having only a modest dental caries prevention effect. As part of efforts to reduce hazardous fluoride ingestion, the practice of artificial water fluoridation should be reconsidered globally, while industrial safety measures need to be tightened in order to reduce unethical discharge of fluoride compounds into the environment.

    Study Links Fluoride To Pre-term Birth And Anemia In Pregnancy

    Fluoride avoidance reduced anemia in pregnant women, decreased pre-term births and enhanced babies’ birth-weight, concludes leading fluoride expert, AK Susheela and colleagues, in a study published in Current Science (May 2010).

    Neurobehavioural Effects of Developmental Toxicity

    This article explains that fluoride is one of 11 known “developmental neurotoxicants” which cause “neurodevelopmental disabilities, including autism, attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments . . . Untested chemicals should not be presumed to be safe. . .”

  • Neurotoxicology and Teratology

    Neurotoxicity of sodium fluoride in rats.

    Fluoride exposures caused sex- and dose-specific behavioral deficits with a common pattern. After fluoride ingestion, the severity of the effect on behavior increased directly with plasma F levels and F concentrations in specific brain regions.

    Developmental Fluoride Neurotoxicity: A Systematic Review and Meta-Analysis

    Although fluoride may cause neurotoxicity in animal models and acute fluoride poisoning causes neurotoxicity in adults, very little is known of its effects on children’s neurodevelopment.

    The results support the possibility of an adverse effect of high fluoride exposure on children’s neurodevelopment. Future research should include detailed individual-level information on prenatal exposure, neurobehavioral performance, and covariates for adjustment.

    New Evidence on Fluoridation

    A review of recent scientific literature reveals a consistent pattern of evidence‚ “hip fractures, skeletal fluorosis, the effect of fluoride on bone structure, fluoride levels in bones and osteosarcomas‚” pointing to the existence of causal mechanisms by which fluoride damages bones. In addition, there is evidence, accepted by some eminent dental researchers and at least one leading United States proponent of fluoridation, that there is negligible benefit from ingesting fluoride, and that any (small) benefit from fluoridation comes from the action of fluoride at the surface of the teeth before fluoridated water is swallowed.

    How Science Can Illuminate Ethical Debates A Case Study On Water Fluoridation

    . . . fluoride, at the levels recommended by pro-fluoridationists for reducing tooth decay,
    is not an essential nutrient; is not a natural substance for babies or for most adults; is not a compulsory medication, but is an expensive-to-avoid medication with an uncontrolled dose; and is harmful to some people.

    When considering the fluoride intakes of infants and comparing them with adult intakes, it is necessary to take into account the large differences in body mass. From the viewpoint of toxicology, the important parameter is the fluoride intake per kg of body mass. Infants drink much larger volumes of liquid, per kg of body mass . . .

    There is a natural physiological mechanism which stops fluoride from getting into breastmilk, whatever the fluoride consumption of the mother.

    The medical dictionaries define ‘medication’ to be ‘impregnation with a medicine’, and a medicine is ‘any drug or remedy’, including a preventive medicine. Since fluoridation puts a medicine, albeit a preventive one, into drinking water, fluoridation is medication.

    Evidence of skeletal fluorosis, with severe clinical manifestations, has been reported in at least 8 studies from 4 countries where water supplies contain fluoride naturally in the range 0.7-2.5 ppm.
