Researchers create a cavity filling to fight off decay  

The best way to avoid developing tooth decay is to practice proper dental health habits. This means brushing, flossing and visiting the dentist twice a year, but sometimes cavities still pop up. Recently, researchers at the University of Maryland School of Dentistry announced a major breakthrough in the field of dental care. According to the scientists, they have created a cavity-filling composite that kills harmful bacteria and regenerates tooth structure.

"Rather than just limiting decay with conventional fillings, the new composite is a revolutionary dental weapon to control harmful bacteria, which co-exist in the natural colony of microorganisms in the mouth," according to researcher Huakun Xu, Ph.D., M.S.

When a dentist drills out a decayed tooth, residual cavity bacteria still remains in the mouth. It's not possible for the dental health professional to get rid of it all, so Xu and his team created the nanocomposites to neutralize that bacteria.

The American Dental Association states that cavities are not something that just kids need to worry about. In fact, the majority of people over age 50 have tooth-root decay.
