Gingivitis means inflammation of the gums. It most commonly develops in response to the biofilm called plaque, which is made up of bacteria. 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. The plaque and tartar irritate the gums. The immune system sends white blood cells to fight the bacteria, and the gums become inflamed. Active inflammation may contribute to formation of clots in blood vessels. Bacteria entering the blood stream activate platelets and increase clotting factors, which work with platelets to form blood clots.
