Bacteria in the pure culture were killed in seconds, whereas bacteria in the plaque samples were killed selectively. Those containing iron-porphyrins were most affected - a beneficial result as it is iron-porphyrins that help bacteria in harming the gums. It is the acidic environment produced by the harmful bugs that results in tooth decay.
