Periodic Videos visits a fluorine expert to show how reactive the element is in action. It also includes a discussion of fluoride and tooth enamel.
Why Hacker News points people here: Recommended in fluoride and fluorine threads as a short, fun demonstration of how nasty fluorine is.

“if you don't know how nasty (and fun) Fluorine is”
Shows how nasty and fun fluorine is, plus tooth enamel.
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).
“I also suggest watching the Periodic Table of Videos episode on Flourine”
Periodic Table of Videos episode on fluorine.
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
“well worth the ~6min”
Interesting fluorine video with a great explanation of tin fluoride for teeth.
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)

A chemist explains fluoride and tooth enamel.
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)
