Grand Rapids, Michigan was the first municipality in the United States to add fluoride to its water system.
No Sedona, Arizona does not put fluoride in it's water supply. In the US over 70 percent of cities and towns put fluoride in the drinking water.
Fluoride is water soluble. It dissolves in water to form fluoride ions.
Boiling water does not remove fluoride. As water evaporates, the fluoride concentration actually increases slightly. Special filters like reverse osmosis systems are needed to effectively remove fluoride from water.

No. Boiling water will not remove fluoride. Distilling it will.
Yes, fluoride can evaporate from water when it is heated.
Pure water does not contain fluoride, but much drinking water does contain fluoride that is deliberately added to reduce tooth decay of children who drink the water. Some drinking water supplies also contain fluoride naturally.
But merely boiling the water will not eliminate the fluoride and can in fact concentrate it because you have the same amount of fluoride in less water. You can distill the water. Meaning you can boil the water then capture the steam, which will be pure. But the process is expensive. You need special filters to remove the fluoride.
What does fluoride seems to be helpful in preventing? Fluoride is found naturally in soil and water. However, because it is helpful in preventing tooth decay and in making teeth stronger, it is also added to water in most cities. Fluoride protects teeth from the demineralization that is caused by acid buildup in the mouth. Further, if there is already damage caused by this acid, fluoride will help strengthen the enamel and remineralize the teeth. Fluoride helps make tooth enamel more resistant to the acid that can damage the enamel and cause cavities.
No, a water softener does not remove fluoride. It only removes hardness-causing minerals like calcium and magnesium. To remove fluoride, you need a different system, like reverse osmosis.
In the U.S. - 1945. However, a lot of cities have naturally fluoridated water. In the U.S., there are a lot of news articles about adding fluoride to water. But for the rest of the world, too much fluoride in the water is a concern and there are lots of programs to remove it down to safe levels.
Fluoride is added to public drinking water to help prevent cavities.
