so, then, if i'm going to do a fluoride treatment, i should do it in the presence of hydroxyapatite, rather than space it out. i want the fluoride to absorb with the hydroxyapatite.

for now, i should make sure that i'm mixing the high fluoride with the novamin, which has the same ions, but in a different combination.

again: i don't know why that wouldn't work, if the ph is high.
