Fillings that do more than just fill in decay? It’s true! Scientists at the University of Maryland have created the first dental filling that not only kills bacteria, but also helps regrow tooth that has been damaged be decay.
Professor Huakun Xu explains,
“Tooth decay means that the mineral content in the tooth has been dissolved by the organic acids secreted by bacteria residing in biofilms or plaques on the tooth surface. These organisms convert carbohydrates to acids that decrease the minerals in the tooth structure.”
These new fillings, called nanocomposites, should last longer than the normal amount of time (five to ten years). More tests must be conducted to confirm this, but this new technology will definitely change the world of dentistry.
