The icon on this page leads to an official Canadian Dental Association (CDA) document demonstrating contradictions between the CDA's claim that fluoridated water is safe and the CDAs guidelines for daily fluoride exposure limits from toothpaste, mouth rinses and oral supplements to protect against children developing dental fluorosis.  In the first pages, fluoridating water is endorsed as a safe way of reducing tooth decay. 

NOTE: Fluoridating water = chemically raising the fluoride levels in a population’s water to
0.7 ppm = 0.7 mg/l = .23mg in a regular glass of water (333ml) = a pea size amount of toothpaste.

 

Then on pages 3 and 4, guidelines to minimize exposure to fluoride from fluoridated toothpaste, mouthwash and oral supplements are incongruous with the idea that it is safe to increase everyone's — and especially children's — overall daily dose of fluoride through fluoridating water. 

 

The dosage .05 to .07 mg fluoride per kg per day is provided as a blood level of fluoride from all sources that the CDA states must not be exceeded to protect against the development of dental fluorosis. 
 

When you do the math, the following are examples of children and people whose fluoride levels would exceed the CDA’s daily limits if the water they drink and prepare food with is fluoridated to .7ppm = .7 mg/l = .23mg in a regular glass of water.
 

  • Formula fed babies whose formula is mixed with fluoridated water.
     

  • Children who regularly consume industrially grown & especially processed foods & drinks that now contain significant levels of fluoride due to:
     

    • The common use of phosphate fertilizer that has increased since the '70s.
       
    • The common use of fluoride-based pesticides that has been increasing since the '70s.
       
    • The processing of foods and drinks with fluoridated water that has been increasing since the '80s.
       

Boxed cereals processed in fluoridated regions, mechanically deboned chicken, tea, especially bottled ice tea and white grape juice are examples of foods that published analysis have shown to contain 6 to 9 times the amount of fluoride found in fluoridated water.

NOTE: The Canadian and American dental associations' guidelines for prescribing oral fluoride supplements is even more contradictory as it stipulates that babies 6 months and younger cannot be given any amount of fluoride and children between 6 months and 3 years of age can be given no more than 0.25 mg of a fluoride supplement per day. This level of fluoride is far below what children, especially formula fed babies, receive when their water is fluoridated to 0.7 ppm = .7 mg/l = .23mg per regular glass of water (333 ml).

Fluoride supplement prescription guidelines also emphasize that
fluoride supplements are only for children living in unfluoridated regions with naturally low levels of fluoride.  Dentists must also assess the child's overall exposure to fluoride from toothpastes, foods and drinks before prescribing fluoride supplements to ensure that their prescription does not lead to fluoride over-exposure and, like school fluoride rinse programs, parents have a choice and the right to consent. None of these considerations are taken into account when dental and medical associations promote water fluoridation policies.
