Although this post is still old, I thought the information would be relative.  In the early 1900's a unseen hand began to wrap it's hands around this world and the US.  The relativity of this is how fluoride negatively effects us.  I cannot argue if or if not fluoride positively effects your teeth.  Fluoride, if it does indeed positively effect tooth decay, is recommended in a topical application only.  This means that drinking it will have -zero- benefit, in fact consuming fluoride is extremely harmful to your body.  Fluoride can be compared to chlorine (something you will likely also find in your water), I won't go into depths concerning what chlorine does to your body, but it is stated that it is the cause of the tremendous rise in heart disease, and a strong increase in cancers of all kinds.

There is a substance that is often handed out like candy to anyone who might feel emotions, these substances are often called 'anti-depressants'.  As shocking as it may come to be learned by anyone, fluoride is a prime ingredient in an anti-depressant.  Why would they put fluoride in an anti-depressant?  Because that is one of the terrible ideas around what fluoride does to the human body and mind, it essentially prevents a person from caring about anything and installing a level of apathy and stupidity in an individual.  Fluoride slows and stops the growth of the brain in human beings, it literally makes them less intelligent.  This substance is being indoctrinated under lies to essentially enslave the human race.  I am a skeptic at heart.  I have much doubt and paranoia in those I trust and love and who I am friends with and meet by chance.  I feel that skepticism and question are natural and essential to your livelihood which is why I implore you to look deeper into the details I have written.  The man behind the counter or the guy with the white jacket might try and tell you something that is untrue, for reasons that involve petty profits and power, but you must always seek the truth.
