A child with a swollen face and a first permanent molar
A 9-year-old boy is brought in by his mother on a Friday afternoon with a 2-day history of right facial swelling. He has a temperature of 38.4°C, is lethargic but alert and drinking, and has a firm, tender swelling of the right buccal space that is closing his right eye slightly. The 46 is grossly carious with a large pulpal exposure, and the 16 is also carious but asymptomatic. He has no known allergies, weighs 28 kg, and has never taken antibiotics before. The practice has no out-of-hours cover and the nearest paediatric emergency department is 25 minutes away. His mother asks if he can just have antibiotics and be seen on Monday.
1. How would you assess the severity of this infection and decide on the urgency of management?
Read the worked answer
This is a spreading odontogenic infection in a child with systemic signs: fever, lethargy and facial swelling. Red flags to check include difficulty swallowing, drooling, trismus, voice change, swelling that is tense and spreading towards the eye or neck, and any airway compromise. Eye closure suggests significant swelling in the buccal and possibly infraorbital region, which warrants urgent referral. Lethargy and fever indicate systemic involvement, and in a child the potential for rapid progression is greater.
Assess airway, breathing and circulation, measure temperature and record observations, and check for trismus and submandibular or neck swelling. Document the dental cause. The presence of systemic signs plus spreading facial swelling means this is not suitable for outpatient antibiotics alone and a Monday review. The correct action is same-day referral to a paediatric or oral and maxillofacial service with emergency department access, with arrangements for intravenous antibiotics and possible drainage.
Explain to the mother that antibiotics alone will not treat the cause, that the source is the infected tooth, and that delay risks the infection spreading to the eye or neck. Give the referral in writing and confirm the receiving team has accepted the patient.
2. What would you do before he leaves, and what definitive dental treatment would you plan afterwards?

Before transfer: do not delay referral to give antibiotics in primary care unless instructed by the receiving team; if antibiotics are started, follow local guidance and the child's weight (28 kg) and record the allergy history. Provide analgesia advice appropriate for his weight and age, ensure he is drinking, and give the mother the referral letter and the emergency department details. Telephone ahead so the department expects him.
Definitive plan: once the acute infection is controlled, the 46 needs pulp therapy or extraction depending on restorability and the stage of root development. In a 9-year-old the 46 root is likely incomplete, so pulpotomy or apexification-type approaches may preserve the tooth; discuss with a paediatric dentist. The 16 also needs restorative care. Prevention is essential: diet and oral hygiene advice, fluoride varnish, and a plan for the other primary and permanent teeth. Arrange follow-up and communicate with his general medical practitioner if he has any relevant history.
Document the referral, the discussion with the mother including the risks of delay, and the fact that she was advised not to wait until Monday. Review the case afterwards to consider whether earlier access could have prevented the admission.
