Periodontal disease is most often preceded by gingivitis, which is a bacterial infection of the gum tissue. A bacterial infection affects the gums when the toxins contained in plaque begin to irritate and inflame the gum tissues. Once this bacterial infection colonizes in the gum pockets between the teeth, it becomes much more difficult to remove and treat. Periodontal disease is a progressive condition that eventually leads to the destruction of the connective tissue and jawbone. If left untreated, it can lead to shifting teeth, loose teeth and eventually tooth loss.
Periodontal disease is the leading cause of tooth loss among adults in the developed world and should always be promptly treated.
Types of Periodontal Disease
When left untreated, gingivitis (mild gum inflammation) can spread to below the gum line. When the gums become irritated by the toxins contained in plaque, a chronic inflammatory response causes the body to break down and destroy its own bone and soft tissue. There may be little or no symptoms as periodontal disease causes the teeth to separate from the infected gum tissue. Deepening pockets between the gums and teeth are generally indicative that soft tissue and bone are being destroyed by periodontal disease.
Here are some of the most common types of periodontal disease:
- Chronic periodontitis – Inflammation within supporting tissues causes deep pockets and gum recession. It may appear the teeth are lengthening, but in actuality, the gums (gingiva) are receding. This is the most common form of periodontal disease and is characterized by progressive loss of attachment, interspersed with periods of rapid progression.
- Aggressive periodontitis – This form of gum disease occurs in an otherwise clinically healthy individual. It is characterized by rapid loss of gum attachment, chronic bone destruction and familial aggregation.
- Necrotizing periodontitis – This form of periodontal disease most often occurs in individuals suffering from systemic conditions such as HIV, immunosuppression and malnutrition. Necrosis (tissue death) occurs in the periodontal ligament, alveolar bone and gingival tissues.
- Periodontitis caused by systemic disease – This form of gum disease often begins at an early age. Medical conditions such as respiratory disease, diabetes and heart disease are common cofactors.
Ask your dentist if you have questions or concerns about periodontal disease, periodontal treatment, or dental implants.
