Types of Gum Disease
A dental disorder that results from progression of gingivitis, involving inflammation and infection of the ligaments and bones that support the teeth.
Pyorrhea – gum disease; Inflammation of gums – involving bone
Causes, incidence, and risk factors:
Continued inflammation eventually causes destruction of the tissues and bone surrounding the tooth. Because plaque contains bacteria, infection is likely and a tooth abscess may also develop, which increases the rate of bone destruction.
Periodontitis caused when inflammation or infection of the gums (gingivitis) is untreated or treatment is delayed. Infection and inflammation spreads from the gums (gingiva) to the ligaments and bone that support the teeth. Loss of support causes the teeth to become loose and eventually fall out. Periodontitis is the primary cause of tooth loss in adults. This disorder is uncommon in childhood but increases during adolescence.
Plaque and tartar (calculus) accumulate at the base of the teeth. Inflammation causes a pocket to develop between the gums and the teeth, which fills with plaque and tartar. Soft tissue swelling traps the plaque in the pocket.
Untreated gingivitis can advance to periodontitis. With time, plaque can spread and grow below the gum line. Toxins produced by the bacteria in plaque irritate the gums. The toxins stimulate a chronic inflammatory response in which the body in essence turns on itself, and the tissues and bone that support the teeth are broken down and destroyed. Gums separate from the teeth, forming pockets (spaces between the teeth and gums) that become infected. As the disease progresses, the pockets deepen and more gum tissue and bone are destroyed. Often, this destructive process has very mild symptoms. Eventually, teeth can become loose and may have to be removed.
There are many forms of periodontitis. The most common ones include the following:
- Aggressive periodontitis occurs in patients who are otherwise clinically healthy. Common features include rapid attachment loss and bone destruction and familial aggregation.
- Chronic periodontitis results in inflammation within the supporting tissues of the teeth, progressive attachment and bone loss. This is the most frequently occurring form of periodontitis and is characterized by pocket formation and/or recession of the gingiva. It is prevalent in adults, but can occur at any age. Progression of attachment loss usually occurs slowly, but periods of rapid progression can occur.
- Periodontitis as a manifestation of systemic diseases often begins at a young age. Systemic conditions such as heart disease, respiratory disease, and diabetes are associated with this form of periodontitis.
- Necrotizing periodontal disease is an infection characterized by necrosis of gingival tissues, periodontal ligament and alveolar bone. These lesions are most commonly observed in individuals with systemic conditions such as HIV infection, malnutrition and immunosuppression.
Healthy gums are firm and pale pink and fit snuggly around teeth. Signs and symptoms of periodontitis can include:
- Swollen or puffy gums
- Bright red, dusky red or purplish gums
- Gums that feel tender when touched
- Gums that bleed easily
- Gums that pull away from your teeth (recede), making your teeth look longer than normal
- New spaces developing between your teeth
- Pus between your teeth and gums
- Bad breath
- Loose teeth
- Painful chewing
- A change in the way your teeth fit together when you bite
