When you visit your dentist, it's highly likely he knows if your water is fluoridated. Since America began fluoridating many municipal water supplies, dentists claim to see healthier teeth in their patients. In communities where water is not fluoridated, dentists can quickly pick out a non-native because these patients tend to have fewer fillings and less tooth decay.
The Centers for Disease Control and Prevention (CDC) has deemed fluoridation to be one of the top 10 greatest public health acheivments of the 20th Century. The EPA also has allowably safe levels of fluoride in the water to minmize the risk of fluoridosis. However, even with the constant monitoring of fluoride levels, many people in the US have a growing concern for the fluoridation of water.
Whether or not water should be fluoridated is a controversial topic. Many people and organizations claim that the fluoridation of water has reduced the number of cavities seen in a person and has increased overall oral health of the US population. Those on the other side of the issue see fluoride as toxic and site studies linking the ingestion of fluoride to toxicity and many other health problems. These same people are also frustrated with the fluoridation of water because it is a chemical which is not easily removed from water. There is no standard carbon water filter which removes the chemical. Only reverse osmosis and distillation systems can remove fluoride.
