Rik - The reason I reacted so stongly to your statement is that very mistaken beliefs around fluoride and the fearful rhetoric cold of harm children if people start to believe it and stop using fluoride toothpaste. The folks at the American Academy of Pediatrics have guidelines that include having fluoride in toothpaste, water, and varnish for children. I'm concerned for the health of our children.

No, aspirin should not be added to water. That is a silly idea. Fluoride, however is already in water, it's in ocean water at more than fluoridated water. Fluoridation is adding just enough to help build tooth enamel - to mimic water where it occurs naturally. 

I'm not going to try and argue every twist from the other respondent. I'm going to spend some time with my child who brushes with toothpaste and drinks fluoridated wate when it's available.
