Pericoronitis
Diagnosis:
Photos of Pericoronits / Operculitis effecting Lower Jaw Wisdom Teeth
Pericoronitis is an inflammatory reaction of the
operculum
(this is the dense, fibrous flap that covers
about 50% of the biting surface of a completely or
partially erupted lower jaw wisdom tooth) covering an
erupting or impacted tooth, usually the lower wisdom
tooth.

Predisposing Factors:

  • Poor oral hygiene
  • Occlusal trauma to the operculum (i.e. the operculum
    is bitten on by upper jaw molars)
  • Gingival (gum) infection
