How can cancer be prevented? Cancers

This bacterium is found in dental plaque. The plaque on our gums and teeth is comprised of a complex structure created by Streptococcus mutans that allow the bacteria to live and survive successfully in our mouths. When these mutans are active they are producing an acid that slowly begins to erode our gums and teeth. Even though this bacterium occurs naturally in even the healthiest
