The first icon on this page leads to an official Canadian Dental Association (CDA) document with highlighted sections demonstrating contradictions between the CDA's claim that fluoridated water is safe & the CDA's guidelines for daily fluoride exposure limits from toothpaste, mouth rinses, oral supplements to protect against children developing dental fluorosis. The second icon link is the exact same document without any highlights confirming that the highlighted document has not been changed in any way.

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 & 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 - .07 mg fluoride / kg / 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 & prepare food with is fluoridated to .7ppm = .7 mg/l = .23mg in a regular glass of water.

NOTE: The Canadian & American dental associations' guidelines for prescribing oral fluoride supplements is even more contradictory as it stipulates that babies 6 months & younger cannot be given any amount of fluoride & children between 6 months & 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 un-fluoridated regions with naturally low levels of fluoride.  Dentists must also assess the child's overall exposure to fluoride from toothpastes, foods & drinks before prescribing fluoride supplements to ensure that their prescription does not lead fluoride over exposure and, like school fluoride rinse programs, parents have a choice & the right to consent. None of these considerations are taken into account when dental and medical associations promote water fluoridation policies.
