What is a periodontal abscess?

A periodontal abscess is a sudden, painful infection in the space between the tooth and the gums. It often arises from a sudden blockage in a deep periodontal pocket, for example by tartar or food debris. The gums swell, become red and tender, and pus may be released. Sometimes there is an unpleasant taste or bad breath. The cause is usually a bacterial infection in already weakened periodontal tissue. Treatment consists of cleaning the pocket and sometimes incising the abscess. Antibiotics may be prescribed if necessary. Prompt treatment prevents the infection from spreading to the surrounding tissues. After healing, further treatment often follows to address the underlying periodontitis. Good oral hygiene and regular check-ups are crucial to prevent a recurrence.
