Fluoride in water supply

Did you know Canada..  right now many communities are in the decision making process of removing fluoride from the water supply.  Just this month Calgary city council voted 10-3 to remove fluoride from their city's drinking water.

There's multiple sides to this controversy - some are saying there is too much fluoride coming from too many sources and to reduce this it should be removed from the local water. It's claimed (citing many studies) that fluoride is a toxic chemical that is an unnecessary drug responsible for cancer, thyroid disease, and reducing IQ.

While others say fluoride in the water supply is a public health measure to achieve optimal oral health, reducing cavities and decay.

What we do know is that too much fluoride can cause fluorosis, it's said to be a cosmetic condition causing white spots on the teeth, and in severe cases the teeth have brown stains. Now some say maybe that's not all fluorosis is causing, it's just the only visible sign.

What's your take?
