Pericoronitis

Pronunciation: pair-ih-core-oh-NY-tis

Inflammation of the soft tissues surrounding the crown of a partially erupted tooth, typically affecting third molars.

Full Definition

Pericoronitis is an inflammatory condition affecting the gingival tissue (operculum) that covers or partially covers an erupting tooth crown. Most commonly associated with mandibular third molars, this condition results from bacterial accumulation beneath the tissue flap where normal oral hygiene is difficult to maintain. Symptoms include pain, swelling, bad taste, and difficulty opening the mouth. Treatment ranges from conservative irrigation and antibiotics for mild cases to operculectomy or tooth extraction for recurrent episodes. Acute pericoronitis may progress to cellulitis or deeper space infections if untreated.

Usage

Usage note: Specify acute versus chronic forms and associated complications in documentation.
