New Nanocomposites May Mean More Durable Tooth Fillings

Caption: A calcium phosphate nanocomposite filling in a tooth. The nanocomposite can "smartly" release decay-fighting agents to buffer against acids produced by bacteria, and rebuild the lost tooth minerals by releasing ions into the mineral-deficient area of the tooth.
