    Microbes that cause cavities can form superorganisms able to ‘crawl’ and spread on teeth
    Three microscopic images labeled with green and blue show a group of microbes changing shape and moving

    In the microbial assemblages, fungal cells (blue) made up the periphery with bacteria (green) in the middle. Fungal hyphae, or elongated filaments, enabled the cluster of microbes to propel itself along the surface of a tooth. (Image: Penn Dental Medicine)

    Microbes that cause cavities can form superorganisms able to ‘crawl’ and spread on teeth

    These multicellular, cross-kingdom assemblages were more resistant to antimicrobials and removal and caused more extensive tooth decay than their single-species equivalents, according to research led by School of Dental Medicine scientists.
