"I am a medical doctor, and I strongly oppose artificial water fluoridation. It is said that if a lie or mistruth is repeated often enough, it will finally be accepted as true.

In this article published by DRUTHERS, Dr. Dickson summarizes the history and challenges of water fluoridation and why fluoridation is NOT safe.

Dr. Bob Dickson, Chair of Fluoride Free Canada


  • In 1945, Grand Rapids, Michigan, became the first community in the world to add fluoride to tap water, on the premise that it would prevent tooth decay.

  • The type of fluoride commonly found in many rocks and the source of the naturally occurring fluoride ion in water supplies is calcium fluoride.

  • The three main fluoride compounds generally used to fluoridate municipal water are industry byproducts: sodium fluoride, hydrofluorosilicic acid (hexafluorosilicic acid) and sodium silicofluoride.

Raw Materials, Manufacture, Toxicity and Public Health Concerns as an Active Ingredient in the Fluoridation of Drinking Water [September 2012]



  • The public water supply is being used to deliver fluoride indiscriminately to every man, woman and child in our communities:

    • Without control of dose (infants and adults alike get the same dose).

    • Without consideration of the age, or nutritional and health status of the recipient (for example, those with a weak kidney or liver can be impacted).

    • Without allowing for the individual’s informed consent on the matter.

  • Dental fluorosis and skeletal weakness

    • Children develop dental fluorosis by ingesting too much fluoride between 0 and 8 years of age. It doesn't matter if the fluoride comes from foods and drinks due to pesticides or processing, or toothpaste, or fluoridated water etc.  ​

    • Those with dental fluorosis have higher bone fractures as well as higher rates of learning disabilities.

  • Thyroid issues:

    • Thyroid medication is the third most prescribed medication to Canadian women, because fluoride is displacing iodine on the cell's receptors.

    • Study shows that adults living in Canada who have moderate-to-severe iodine deficiencies and higher levels of urinary fluoride may be at an increased risk for underactive thyroid gland activity.

  • Irritable Bowel Syndrome (IBS)

    • Paul Connett interviews Dr. A. K. Susheela from India, who discusses how ingesting fluoride irritates the stomach lining, leading to IBS. She discovered that from the moment you eliminate fluoride, the gastrointestinal mucosa and the microvilli will regenerate within 10-12 days.

    • Canada has one of the highest prevalence of IBS in the world – estimated 18% vs. 11% globally. (Lovell et al. 2012).
