History of Present Illness
Patient presents to the ED following a bar fight. He sustained blunt facial trauma resulting in the complete avulsion of tooth number eight. Patient was initially evaluated, deemed stable, and prepped for discharge before the unaccounted missing tooth was noted during morning rounds.

Morning Rounds & Reassessment
Reviewing patient for planned discharge.
Medical Decision Making
Noticed tooth #8 was avulsed and missing. When the patient could not account for the tooth's location ('Fuck if I know'), the attending correctly halted the discharge. An unaccounted missing tooth in a trauma patient with altered sensorium (from alcohol/head trauma) must be assumed aspirated or swallowed. Aspiration poses a severe threat to the airway and pulmonary parenchyma.
Diagnostics & Findings
- Chest X-ray (CXR)
Findings:
- Complete avulsion of tooth #8
- Tooth unaccounted for
Interventions
- Discharge cancelled
⮑ Outcome & Reassessment
Patient remained stable and was sent to radiology for the ordered Chest X-ray.
Lab/Diagnostic Review
Chest X-ray results resulted.
Lab/Diagnostic Review
Chest X-ray results resulted.
Medical Decision Making
CXR confirmed the presence of the aspirated tooth in the lungs. An aspirated tooth is a nidus for bacteria (especially oral flora) and causes post-obstructive pneumonitis, which frequently progresses to a life-threatening lung abscess or necrotizing pneumonia if not retrieved. Immediate pulmonary consultation is required for bronchoscopy.
Diagnostics & Findings
- Chest X-ray (Reviewed)
Findings:
- Aspirated tooth visualized on Chest X-ray.
Interventions
- Consulted Pulmonology for foreign body retrieval.
⮑ Outcome & Reassessment
Diagnosis of foreign body aspiration confirmed; patient prepped for definitive pulmonary intervention.
Diagnoses & Disposition
Evolving Diagnoses
- [Morning Rounds]Avulsion of tooth #8
- [Diagnostic Review]Tracheobronchial foreign body aspiration (aspirated tooth)
Current Disposition
Admitted to Pulmonology / Awaiting Bronchoscopy
Casebook Analysis
Episode Context
This case functions as a brief, high-yield 'catch' during morning rounds to establish the baseline competence of the attending physician (Dr. Robby) and emphasize the rigorous attention to detail required in emergency medicine, while contrasting with the initial resident who was ready to mistakenly discharge the patient.
Attending's Review
Medical Accuracy
Highly accurate. In emergency and trauma medicine, a missing tooth must be accounted for. If it cannot be located, a chest X-ray is the gold standard next step to rule out aspiration. The show accurately states that discharging the patient would have likely led to a fatal lung abscess within a week due to anaerobic oral bacteria.
Complications & Errors
- Diagnostic Error: The initial resident or provider who saw Charlie failed to account for the avulsed tooth and incorrectly cleared the patient for discharge. This is a classic 'anchoring bias' or 'premature closure' error where the provider treated the superficial trauma but missed the hidden threat.
Clinical Pearls
Always account for missing teeth in maxillofacial trauma. If the tooth is not outside the body, assume it is in the lungs or the stomach until proven otherwise by imaging.
Aspirated foreign bodies in adults frequently lodge in the right mainstem bronchus because it is wider, shorter, and more vertical than the left.
Untreated foreign body aspiration (especially a tooth covered in oral flora) carries a massive risk for post-obstructive pneumonia, lung abscess, and empyema.
