What does “Periodontal abscess” mean?
A periodontal abscess is an acute, localized collection of pus in tooth-supporting tissues, such as the wall of a periodontal pocket. Pain, swelling, and rapidly progressing tissue damage may occur, requiring assessment and treatment of the cause.
Deep pockets and acute changes
It often occurs in an existing periodontal pocket but can also develop without previous periodontitis, for example due to foreign material. Gum swelling, pus, pain on chewing, and tooth mobility may occur. Visible drainage does not mean the cause has resolved.
Distinguishing infection inside the tooth
Pocket probing, pulp responses, and radiographs distinguish a periodontal origin, a root canal origin, or both. Cracks and other causes are also assessed when needed. Diagnosis determines the need for drainage, local cleaning, root canal treatment, and subsequent periodontal care.
Care after emergency treatment
Drainage and removal of the infection source are important; antibiotics alone do not complete treatment. Their use depends on spreading infection or systemic symptoms. After acute symptoms settle, periodontal status is reassessed and treatment and maintenance are planned to prevent recurrence.
Frequently Asked Questions
Will antibiotics alone make it better?
A procedure to address the local cause and pus may be needed. Antibiotics are not automatically used for every abscess, and leftover medication should not be taken on your own.
Which symptoms need immediate care?
Seek prompt care if swelling spreads rapidly or fever develops. Difficulty breathing or swallowing, or severe mouth or facial swelling, requires emergency assessment.
