I'm not sure what your first quesiton was about, but I can answer your second question.

Fluoride is a natural mineral that occurs in many places all over the world.

Fluoridated water is a process where nuclear power plants take the Uranium Yellow Cake that is produced through nuclear fusion, and they break it down. The use what they want and the waste from the Yellow Cake is known as Hexafluorisilicic Acid. They take this toxic waste, call it "Fluoride" to deceive people and add it to our water supply. It was also used by Hitler to dumb down people when he was attempting to take over.

Currently, the US is one of the few places left that still has water fluoridation because it is a posionous and unnatural compound. There has been some proof that it can help teeth on a topical level, but even that is debated and almost everyone who isn't being paid by the CDC, Big Pharma or the Gov, agrees that it has no business being in peoples water.

Fluoride is actually just a natural mineral. It's not best in large amounts, but is helpful in very small amounts and is naturally found in many places.

Flouridated water is a whole nother subject. They tell you that they simply add "fluoride" to the water, when in fact, what they add is actually called "hexyfluorasilic acid" (I might have spelled that wrong), which is a waste product made from uranium yellow cake used in Nuclear power plants. The reason they put it into the water, is to cut down on how much radioactive waste is stored away, because radioactive waste takes anywhere from 50 to 50,000 years to break down into safe waste. They tell you that it's just "fluoride", because when you look up the mineral fluoride, it doesn't seem all that bad, and they don't want you to know they are really poisoning the water. Sadly, only a few countries actually recogize the difference and have banned fluoridated water.

Hexyfluorasilic acid is very corrosive and because of this, anyone who handles it needs to wear hazmat suits and gear to avoid being burnt or poisoned. Each area uses different amouns of it in their water system, so it can very on how many "bags" they use.
