Me too -- although I think that fluoride detox can be a culprit in convincing people that Fl is good. c.f. Fl-based antidepressants.
Spdina, you may want to look at some of our old posts from about a year ago where we did a lot of teeth-health discussion and research. (Also a lot about the dangers of Fl on the Iodine forum, and I'm sure Wombat and V and Trapper could point you in the right direction over there!) But Fl is of questionable efficacy even when topically applied, and ingested, it's of no help in preventing tooth decay and in fact is harmful to bones. Much research supporting this. Fluoridealert.org is a great clearninghouse for this info, well documented.
Don't mean to be a contrarian, but if you do the research you will never want to drink water with Fl, brush with it, ingest foods or drugs that contain it, etc. again.
Let me know if I can send you my Flouride Primer (send me your e-mail and I will send it to you!)
I brush with oil and then xylitol, Sea Salt and baking soda and my teeth are clean and strong...
The other teeth rebuilder is to eat raw milk and also dessicated bone wafers for teeth and bone-replenishing minerals.
