Periodontal disease (also known as periodontitis and gum disease) is a progressive condition and the leading cause of tooth loss amongst adults in the developed world. Periodontal disease occurs when the toxins found in plaque begin to irritate or inflame the gingiva (gum tissue). The resulting bacterial infection often known as gingivitis, can eventually lead to the destruction of the gum tissue and underlying bone. If periodontal disease is not treated, it can also lead to loose teeth or tooth loss.
There are many common types of periodontal disease including aggressive, chronic, necrotizing periodontitis, and periodontitis associated with systemic diseases. Each of these types of periodontal disease has its own distinct characteristics and symptoms, and all require prompt treatment by a dentist to halt subsequent bone and tissue loss.
