• Dental subluxation
• Dental avulsion
• Bleeding dental socket

Odontogenic Infections

• Acute necrotizing ulcerative gingivitis (trench mouth)
• Dental abscess

Other

• Scurvy
• Gingival hyperplasia
  • Phenytoin
  • Cyclosporine
  • Nifedipine, Amlodipine
  • Leukemia

Evaluation

• Occurs 2-4d after tooth extraction
• Initial post-extraction pain subsides followed by sudden/severe pain at extraction site
• Physical exam often unremarkable

Management

• Analgesia (often requires dental block)
• Irrigate and suction
• Pack with iodoform ribbon gauze soaked with eugenol (oil of cloves) or local anesthetic
