I believe that the hydroxyapatite found in enamel is also the same that is found in bone. It may not possible to modify one without the other thus there may be some broader-reaching toxicities associated with this application of fluoride, especially when you are talking about incorporating it into developing systems. Your teeth may be better off, but the damage that was incurred during bone development way outweighs it. Evolution may have avoided/eliminated direct exposure to fluoride during these sensitive time periods and instead opted for later incorporation via exposure of the external compartment. Of course, this is purely hypothetical.
