Gum disease is a range of conditions involving the supporting tissues of the teeth. It has two stages known as gingivitis and periodontitis. Gingivitis is the earlier stage, affecting only the surface tissues seen in the mouth and caused by bacteria accumulation, which later form into plaque and calculus near the teeth.
Once this happens, the gums bleed easily, which often occurs when you eat or brush your teeth. Without early diagnosis and treatment, gingivitis advances to a more serious form of gum disease called periodontitis. The latter condition affects the deeper tissues like ligaments, root surfaces and jawbone. Periodontitis can proceed to complications such as receding gums, abscesses and trench mouth including tooth loss and even bone loss.
