  • A more virulent infection into the alveolus produces alveolar periostitis.
  • Infection spreads from pulp or from gingivitis to produce the periostitis.
  • This may then break out of the alveolus into the bone causing osteomyelitis.
    • Seen in infection of carnassial teeth in dogs as chronic sinus discharging below eye. So called 'malar' abscess.
  • Only treated by removal of tooth.
  • Abscess may break through into maxillary sinus. If drained will get recovery.
    • Other maxillary cheek teeth can be involved in pyaemic infection with sinus formation.
  • Hard to evaluate on mandible, may produce fistula that also needs tooth removal.
