What is pericoronitis?

Pericoronitis is a painful inflammation of the gum around a partially erupted tooth. It most commonly occurs with wisdom teeth in the lower jaw. Symptoms include pain, swelling, difficulty opening the mouth and sometimes fever. Bacteria and food debris become trapped under the flap of gum tissue. Mild cases can be treated with rinses and antibiotics. In the case of recurrent infections, extraction of the affected tooth is recommended. Thorough cleaning of the area can provide temporary relief. Rinsing with warm salt water helps to reduce the inflammation. If left untreated, the infection can spread to other areas. Prompt treatment prevents complications and more serious infections.
