I'd laugh so hard if one of you guys had serious health problems caused by Flouride, which would mean Jinx was right all along.
Joke aside, I think that, while you shouldn't believe every last part of the video just yet, you shouldn't completely cast it away, either. I found something about the guy in the video and I think he knows what he's talking about:

Also, I hardly ever brush my teeth, and I haven't had a toothache in about 5 years. Now I think that here in Serbia, water isn't flouridated (not completely sure but I think they only use chlorine), but I'm more than sure there's flouride in our toothpaste.
I say stay open-minded. Don't ignore potentially correct information when it's staring you in the face just because the majority of this forum is doing so, at least in this case.
