Periodontal Abscess

Consider local measures in the first instance. Antibiotics are only indicated as an adjunct to treatment where there is pyrexia, evidence of systemic spread and local lymph gland involvement or where local measures are ineffective.

Broad-spectrum antibiotics, such as clindamycin, cephalosporins or co-amoxiclav, are rarely indicated in routine dentistry and have the potential to cause adverse effects and contribute to the development of antibiotic resistance.

Local Measures

  • If pus is present in a periodontal abscess drain by root surface debridement through the pocket or by extraction of the tooth.
  • If pus is present in the soft tissue attempt incision.


If antibiotics deemed clinically indicated, follow recommendations for Acute Dento-Alveolar Infection.
