Gingivitis means inflammation of the gums. It most commonly develops in response to the biofilm called plaque, which is made up of bacteria. Once the bacteria are anchored, they bind to other bacteria floating around the mouth to form a kind of web. As the web grows, it can hold onto more bacteria and the plaque thickens. When the plaque is allowed to build up, it attracts more types of bacteria. Over time, it hardens at the base of the teeth into a material called tartar.
