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. 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.
Continued inflammation eventually causes destruction of the tissues surrounding the tooth. Because plaque contains bacteria, infection is likely and tooth abscess may also develop, which increases the rate of bone destruction. Good oral hygiene , including thorough tooth brushing and flossing, and regular professional dental cleaning, is the best means of prevention. The prevention and treatment of gingivitis reduces the risk of development of periodontitis. Early symptoms resemble gingivitis .
