When gingivitis is left untreated, the bacteria go on to produce more damage which is not reversible. The enzymes and toxins produced by oral bacteria break down the ligament that holds the tooth in place and subsequently resorbs the bone that supports the teeth. During this process the gum detaches from the teeth and form pockets where even more plaque accumulates. This is called Chronic Periodontitis or more commonly gum disease. Unfortunately periodontitis or gum disease is very insidious in its progression and often symptoms are only experienced at a very late stage when the majority of the bone is lost and the nerve becomes infected. At this stage the only option is extraction. It is therefore imperative that early warning signs are heeded and treatment sought at an early stage.
