CDC: “Two studies reported that extended consumption of infant formula beyond age 10–12 months was a risk factor for enamel fluorosis, especially when formula concentrate was mixed with fluoridated water…The Iowa study also reported that infant formula and processed baby food contained variable amounts of fluoride.”
ME: So are you asking formula and baby foods also be fluoride labeled?
ME: So, if ingested fluoride doesn’t reduce tooth decay and if saliva fluoride levels aren’t high enough to prevent tooth decay, what good is fluoridation?
CDC: “ drinking fluoridated water, brushing with fluoride toothpaste, or using other fluoride dental products can raise the concentration of fluoride in saliva present in the mouth 100- to 1,000-fold.”
ME: When I do the math this works out to 0.6 ppm to 6 ppm in non-fluoridated communities and 1.6 – 16 ppm in fluoridated communities. Isn’t that high enough to cause fluorosis since all fluorides get absorbed into the bloodstream via the mucous membranes of the mouth and some fluoridated dental products get swallowed inadvertently.
CDC: The concentration returns to previous levels within 1–2 hours but, during this time, saliva serves as an important source of fluoride for concentration in plaque and for tooth remineralization.
ME: Assuming you haven’t brushed away the plaque. But you didn’t answer my fluorosis question.
CDC: “Some persons choose to modify this condition with elective cosmetic treatment”
ME: Is this cost factored into the cost/benefit of water fluoridation?
CDC: “most persons would be classified as low risk (for cavities) at any given time.”
ME: There you go again changing the subject. So, if the dentist isn’t sure, he/she treats my child as a low risk cavity person.
CDC: “when classification is uncertain, treating a person as high risk is prudent until further information or experience allows a more accurate assessment. This assumption increases the immediate cost of caries prevention or treatment and might increase the risk for enamel fluorosis for children aged
