Correct answer: D — Dental abscess with facial cellulitis

Post-dental procedure facial swelling with fever and trismus suggests dental abscess with associated facial cellulitis or deep space infection. Management includes IV antibiotics (amoxicillin-clavulanate or flucloxacillin + metronidazole), dental review, and consideration of imaging (CT) if deep space infection is suspected.
