Here is the American Dental Assoc statement saying "fluoride in water PREVENTS DISEASE - tooth decay", again.  The link to it in my previous post doesn't work, hopefully this will.  It works in an email so it should work here.  If not just google 5 Reasons why fluoride in water is good for communities, and read #1. No, I'm not pro fluoride, no, no, again I say no!

Therefore if fluoride prevents disease it is by definition a medicine.

1) According to Websters dictionary Medicine is "the science and art of dealing with the maintenance of health and the PREVENTION, Alleviation, or Cure of Disease." 

Now, please don't argue with me over this.  Argue with the almighty ADA, and Webster's Dictionary.  But now I expect the advocates to say the ADA, and Webster's Dictionary are bogus, lol.  Some people's kids ;oD.
