A dental disorder that results from progression of gingivitis , involving inflammation and infection of the ligaments and bones 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. 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. Early symptoms resemble gingivitis . Deposits of plaque and calculus may be visible at the base of the teeth, with enlarged pockets in the gums. The gums are usually painless or mildly tender, unless a tooth abscess is also present.
