Background
- Occurs during tooth eruption through the gingiva
- Food and bacteria can accumulate between the erupting tooth and operculum (flap of gingiva) leading to infection and pain
- The wisdom tooth (3rd molar) is the most common site of pericoronitis
Clinical Features
- Pain at site of recent tooth eruption with operculum
Differential Diagnosis
Dentoalveolar Injuries
Odontogenic Infections
- Acute alveolar osteitis (dry socket)
- Acute necrotizing ulcerative gingivitis (trench mouth)
- Dental abscess
- Periapical abscess
- Periodontal abscess
- Ludwig's angina
- Pulpitis (dental caries)
- Pericoronitis
- Peritonsillar abscess (PTA)
- Retropharyngeal abscess
- Vincent's angina - tonsillitis and pharyngitis
Other
Evaluation
- Clinical diagnosis
Management
- Analgesia (often requires dental block)
- Treat with chlorhexidine rinses, a randomized trial showed green tee was equally effective [1]
- ED debridement of the operculum or debris is usually not indicated
- Refer to dentist for surgical excision of the operculum and/or removal of the offending tooth
- Severe pericoronitis can be treated with oral antibiotics.
- Penicillin VK 500mg PO QID OR clindamycin 300mg PO QID
Disposition
- Discharge with dental follow-up
