Dental Abscess

Regular analgesia should be first option until a dentist can be seen for urgent drainage, as repeated courses of antibiotics for abscess are not appropriate. Repeated antibiotics alone, without drainage are ineffective in preventing spread of infection.

Antibiotics are only recommended if there are signs of severe infection, systemic symptoms or high risk of complications.

 

If spreading infection (lymph node involvement, or systemic signs ie fever or malaise) ADD metronidazole.

True penicillin allergy: use clarithromycin
