Tiny particles strenthen the compound used to fill teeth, ward off infection. Nanodiamonds may help patients that have had the dreaded root canal. Dental researchers have developed a nanodiamond-reinforced version of gutta percha, the compound that is used to fill void spaces in dental root canals to prevent infection that can lead to tooth loss. Tested in patient-extracted teeth, the nanodiamond-embedded polymer was substantially stronger than conventional gutta percha...
