Just out of interest, and not detracting from what you're saying, but normal fluoride also forms a compound (flouro-apetite) more resistant to avoid than normal tooth material (appetite). At least according to this chemist: this video (tooth chat at 5:10, but the whole video is interesting)
This is a good little interesting video on fluorine here (previously linked by someone else), and the ending is the best description of tin fluoride for teeth I've ever seen -- well worth the ~6min this video (edit: added link)
Every time I hear anything about Flourine, I’m reminded of “Sand Won’t Save You This Time” [LINK] I also suggest watching the Periodic Table of Videos episode on Flourine: this video
An educational video from Univ. of Nottingham, if you don't know how nasty (and fun) Fluorine is: this video (and they explain the tooth enamel theory towards the end as well).
