Periodontitis is inflammation of the gums and supporting structures of the teeth. It is one of the most common human diseases.
Periodontal Diseases are caused by certain bacteria (known as periodontal bacteria) and by the local inflammation triggered by those bacteria. Although these periodontal bacteria are naturally present in the mouth, they are only harmful when the conditions are right for them to increase dramatically in numbers. This happens when a layer of bacteria and food debris, known as plaque, builds up and is left undisturbed on the teeth, commonly in hard-to-reach areas such as between the teeth.
