A patient has a fractured root tip of tooth #18 (mandibular third molar), presents with inability to swallow and dyspnea, and has active infection. The BEST management is:

Correct answer: D. Hospitalize immediately and manage airway; extract under general anesthesia

• A. Supplemental oxygen addresses oxygenation but does not treat the airway obstruction or infection causing dyspnea.
• B. Prescribing antibiotics and delaying treatment is inappropriate when the airway is threatened.
• C. Attempting office extraction with local anesthesia in a patient with compromised airway and deep space infection is dangerous and insufficient.
• D. Correct. Dyspnea (breathing difficulty) with inability to swallow in the context of a deep dental infection signals imminent airway compromise. This is a life-threatening emergency requiring immediate hospitalization, airway management (potentially intubation or tracheostomy), IV antibiotics, and surgical drainage/extraction under controlled conditions.
