You invited me, David Kennedy, DDS, as one of the persons interviewed in this film to participate in your blog and I accept with one caveat, we talk about solid science and not opinions. Agreed?
The solid science I would like to address involves the dose of fluoride we receive from water fluoridation with hydrofluosilicic acid especially infants on tap-water-formula. The US EPA has what they call a presumably toxic dose (PTD) of 5 mg/kg which is presumably an acute dose that would be lethal to a substantial portion of the population. They also have a Reference Dose (RfD) of 0.06 mg/kg which is their minimum risk level (MRL) above which certain members of the population will develop adverse health effects. Both these dosages are obviously very out of date as the most recent review by the National Academy of Science in 2006 (Table 8-2) you will notice that injury to thyroid occurs at substantially lower doses.
So my question to you is; what dose of fluoride you would recommend a baby receive? And while you are explaining that dose please explain the rationale for giving a baby a systemic dose of a xenobiotic in an attempt to provide a topical dose of that agent.
