“A team of bioengineers have created the first cavity-filling composite that destroys harmful bacteria and restores tooth enamel lost by decay.
Instead of just limiting tooth decay with conventional fillings, the new material, made with nanotechnology, controls destructive bacteria that co-exist in the natural colony of microbes in the mouth and to rebuild the tooth’s minerals, according to lead researcher Professor Huakun Xu from Maryland University School of Dentistry.”
