Fluoride is a mineral that comes from a substance called fluorine. It is the 13th most abundant element in the universe. In case you were wondering, the top 3 most abundant elements are oxygen, helium and hydrogen. Fluorine, on the other hand, is a substance that naturally appears in water and air. This is why its compounds are all around us and you can find them in lots of everyday objects. In fact, it is possible to find fluorine in things like non-stick frying pans, fridges and Prozac. The most popular use for fluoride is its ability to help your teeth prevent tooth decay. This is because there is a lot of credible scientific studies and evidence supporting this idea. It is also the reason why it is recommended by most dentists. However, there are many governments that routinely add fluoride to the water supply. They do this under the guise of protecting the dental health of their population. This started in the early 20th century where most public water supplies contain some fluoride. Seeing this to be a success the water fluoride schemes are continuing to this day. These types of public water fluoridation schemes are still in place 70 years later. This is because 1945 is the start date in the US and 1964 in the UK. So now that we know there is a lot of water fluorination especially in government supplied tap water. The real question is whether fluoride is really harmful to health and, if it is how do you remove it?
