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.
Yes hydrogen fluoride can be dissolved in pure water.
no
Only filters that use reverse osmosis or activated alumina are effective at removing fluoride from tap water. "Brita" filters do not remove fluoride. Source: http://www.ewg.org/EWGFAQ#
Fluorides are water soluble.
Not all towns fluoridate the water; Sacramento, CA, for example, does not. Most bottled water is fluoride-free. However, fluoridated water causes very few health problems.
yes
No. Boiling water will not remove fluoride. Distilling it will.
Fluoride is added to drinking water to prevent tooth decay
Sodium fluoride dissolves in water but does not chemically react with water.
Yes hydrogen fluoride can be dissolved in pure water.
Fluoride is added to public drinking water to help prevent cavities.
usually bottled water does not have fluoride in it unless they advertise that it does (like nursery water or water specifically for kids they may add fluoride to those)
Distillation does remove at least some fluoride - this is why a dentist will recommend fluoride treatment at your 6-month dental cleaning if you drink distilled or filtered water. However, to get all the fluoride out the water would have to be deionized.
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.
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.
No, most natural dietary fluoride comes from mineral deposits containing fluoride salts, this then leaches into drinking water. But with only a few rare exceptions this is rare. Most municipal water supplies have fluoride added and this would overwhelm any natural dietary fluoride sources.
Healthier Teeth is a pro, as a dentist I would suggest only brushing your teeth with toothpaste that has fluoride in it. Fluoride is actually a poison if swallowed in large amounts, so purify your water if it contains fluoride in it.
