In Japan, scientists have created a new tool that many believe will help prevent tooth decay in the future. They call it the “tooth patch,” an ultra-flexible biocompatible film that scientists have designed to fit snugly over the surface of teeth. The film is made entirely of hydroxyapatite, the natural mineral from which tooth enamel is made. The developers of the tooth patch hope that it’s enamel-like composition will make it an effective shield to prevent tooth decay, as well as a restorative material that can be used to repair teeth with pre-existing cavities or dental caries.
Over the past year, the anti-fluoride movement has gained substantial momentum as communities from across the United States have begun to vote against public water fluoridation. Just recently, 3 communities in Indiana have voted to end the fluoridation of their water supplies. Those communities are Walkerton, North Liberty, and Lakeville, home to a combined 5,000 or more individuals who are now safe from fluoride exposure. Other communities in which the anti-fluoride movement is strong include Wichita, Portland, and Santa Fe.
