In exceptional circumstances patients may be unable to access dental services in a timely manner; in which case, the guidance below is designed for the management of acute oral conditions pending review by a dental specialist.
See guidance in section 12.3 Oropharynx
Temporary pain and swelling relief can be attained with saline mouthwash.
Use antiseptic mouthwash if more severe & pain limits oral hygiene to treat or prevent secondary infection.
The primary cause for mucosal ulceration or inflammation (aphthous ulcers, oral lichen planus, herpes simplex infection, oral cancer) needs to be evaluated and treated.

Commence metronidazole and refer to dentist for scaling and oral hygiene advice.
Refer to dentist for irrigation & debridement.
Use antiseptic mouthwash if pain and trismus limit oral hygiene
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 recommended if there are signs of severe infection, systemic symptoms or high risk of complications.
Severe odontogenic infections; defined as:
Refer urgently for admission to protect airway, achieve surgical drainage and IV antibiotics.
The empirical use of cephalosporins, co-amoxiclav, clarithromycin, and clindamycin do not offer any advantage for most dental patients and should only be used if no response to first line drugs when referral is the preferred option.
If pus drain by incision, tooth extraction or via root canal. Send pus for microbiology.
Metronidazole is a suitable alternative for the management of dental abscess in patients who are allergic to penicillin. It can also be used as an adjunct to amoxicillin in patients with spreading infection (lymph node involvement, or systemic signs i.e. fever or malaise) or pyrexia.
