A 40-year-old woman with worsening mouth pain and facial swelling after extraction of a mandibular molar; she cannot fully open her mouth. Which is the most appropriate management?

• A. Oral antibiotics
• B. Observation
• C. CT scan
• D. Transfer to the emergency department

Answer: (D)

Recognizing a rapidly spreading dental infection that threatens the airway is the key idea here. Worsening mouth pain, facial swelling after a tooth extraction, and inability to fully open the mouth point to infection spreading into the facial spaces, which can quickly progress to airway obstruction (think of a dangerous process like Ludwig’s angina). The safest, most appropriate step is urgent transfer to the emergency department for immediate evaluation and stabilization. In the ED, clinicians can assess the airway, start IV broad-spectrum antibiotics, provide pain control and fluids, and determine the need for surgical drainage or airway management. Oral antibiotics alone won’t address the risk of airway compromise, and observation is unsafe given the potential for rapid deterioration. CT scanning can help delineate the extent of infection, but it should not delay access to urgent ED care where definitive treatment can begin.
