Gingivitis is a mild, often reversible form of gum disease. If left untreated, gingivitis can progress to a serious condition called periodontitis.

A substance that forms on teeth called plaque causes gingivitis. Plaque is a sticky material, composed of bacteria, mucus, food, and other substances. It hardens to form tartar or calculus. When plaque is left on the teeth for an extended period of time, it can lead to gingivitis. Toxins produced by bacteria in dental plaque irritate the gum tissue and cause infection, inflammation, and pain.
