Pericoronitis

What is pericoronitis?

Pericoronitis is inflammation of the gum tissue surrounding the crown portion of a tooth. Pericoronitis usually affects the lower third molar (wisdom) tooth where gum tissue overlaps the chewing surface of the tooth. Pericoronitis can be either chronic or acute. Chronic (or recurrent) pericoronitis is a mild persistent inflammation of the area. Acute pericoronitis is when the symptoms intensify to fever, swelling, and pain which indicate a spreading infection.

Pericoronitis is differentiated from gum disease (or periodontitis) in that it occurs specifically around a partially erupting tooth. The cause of this condition is similar to the formation of a gum abscess in periodontitis by the entrapment of debris under the gum tissue.

What causes pericoronitis?

The primary cause for pericoronitis is accumulation of bacteria. Usually, the tooth is only partially exposed (erupted) and forms excess gum tissue that overlaps the tooth. Bacteria and food debris gets trapped in the space between the tooth and the overlapping gum. This overlapping gum is called an "operculum." Active infection is associated with an abscess that contains pus, which has the ability to spread if left unattended.

Who is at risk for pericoronitis?

Most commonly, pericoronitis affects young adults and people in their mid-20s who are dealing with poorly erupting wisdom teeth.

What are the signs and symptoms of pericoronitis?

Symptoms of pericoronitis can range from mild to severe and include pain, swelling of the gums, tenderness, redness of gum tissue, bad breath, bad taste from pus, difficulty opening the jaw, difficulty swallowing, swelling of the lymph nodes, fever, loss of appetite, and feeling unwell.
