Immediate Treatment for a Broken Infected Tooth in the Emergency Room

The immediate treatment for a broken infected tooth in the emergency room includes pain management with NSAIDs (ibuprofen) or acetaminophen, antibiotics if there is evidence of infection, and appropriate referral to a dentist based on the severity of the fracture and presence of pulp exposure. 1

Assessment and Classification of Tooth Fracture

  • Tooth fractures should be classified based on the extent of damage to determine appropriate management and urgency of dental referral 2:
    • Enamel-only fractures (uncomplicated): Minimal sensitivity, no immediate dental referral needed 2
    • Enamel and dentin fractures (uncomplicated): May cause sensitivity, referral within a few days 2
    • Crown fractures with exposed pulp (complicated): Require immediate dental referral for appropriate pulp therapy 2

Immediate Management in the ER

Pain Control

  • Administer NSAIDs such as ibuprofen as first-line treatment for pain management 1
  • Acetaminophen is an alternative when NSAIDs are contraindicated 1
  • Apply cold compresses to reduce swelling and discomfort 1

Antibiotic Therapy for Infection

  • For infected teeth with evidence of spreading infection or cellulitis, antibiotics should be prescribed 3, 4:
    • First-line: Penicillin V or amoxicillin 3
      • Adult dosage: 500 mg every 8 hours or 875 mg every 12 hours 5
    • For penicillin-allergic patients: Clindamycin is preferred over macrolides 3
      • Adult dosage: Based on severity of infection and renal function 6

Preservation of Tooth Fragments

  • If tooth fragments are available, they should be stored properly for possible reattachment by the dentist 1
  • Do not store tooth fragments in water as this causes osmotic lysis of cells 2
  • Appropriate storage media include milk or saline solution 1

Referral Guidelines Based on Severity

  • Immediate dental referral (same day) is necessary for 1:

    • Crown fractures with pulp exposure
    • Severe mobility
    • Significant pain or evidence of infection
  • Referral within a few days is recommended for 1:

    • Enamel and dentin fractures with sensitivity
    • Cases with moderate pain but no pulp exposure
  • Less urgent referral (within a week) is suitable for 2:

    • Enamel-only fractures with minimal symptoms

Special Considerations for Infected Teeth

  • Drainage of abscesses may be necessary alongside antibiotic therapy 4

  • In cases of severe infection with cellulitis, more aggressive antibiotic therapy may be required 3:

    • Second-line regimens include amoxicillin-clavulanate, cefuroxime, or penicillin with metronidazole 3
  • Some evidence suggests that immediate extraction of severely infected teeth may be beneficial for faster resolution of infection, decreased pain, and earlier return of function 7

Common Pitfalls to Avoid

  • Delaying referral for crown fractures with pulp exposure can lead to pulpal necrosis 1
  • Underestimating pain from dentin exposure requires prompt coverage to prevent bacterial contamination 2
  • Using water to store avulsed teeth or tooth fragments causes osmotic lysis of cells 2
  • Failing to prescribe antibiotics in cases of spreading infection or cellulitis 4
  • Over-aggressive removal of infected dentin in deep cavities can lead to pulp exposure and necessitate root canal treatment 8
