Pericoronitis is an acute infection in which there occurs the inflammation of gingival and surrounding soft tissues around an incompletely erupted tooth and the most infected one is the area around 3rd molar or wisdom tooth.
Signs and Symptoms of Pericoronitis

Types of Pericoronitis
There are three types of Pericoronitis and these are Acute, Sub-acute and chronic. The most common that is seen amongst the people is the acute type of Pericoronitis.
This is defined by varying degree of involvement of pericoronal flap as well as systemic complications. This infected flap gets traumatized by contact with the opposing jaw and inflammatory involvement is aggravated.
Lymphadenitis is a common finding of the Pericoronitis and the patient can be detected with complications like having fever and malaise.
Complications of Pericoronitis
• The involvement may become localized to some limit and this can result in the formation of Pericoronal abscess.
• Due to the existence of Pericoronitis mainly exists in the partially erupted tooth this can lead to cyst formation.
• This infection can spread through the ear, nose and throat to the floor of mouth and thus the engulfing action of the person can become impossible to perform.
• There are some complications that can be life threatening related to Pericoronitis and these are Cellulitis and Ludwig’s Angina.
Treatment of Pericoronitis
When the patient diagnosed with Pericoronitis come to the dentist the following procedure is followed:
-The infected area is irrigated properly with warm water to remove the superficial impacted food contents and the exudates and then the application of some topical anaesthetic agent is given to the infected area.
-Then the flap is reflected with a scaler and the underlying impacted food is again flushed out with the warm water irrigation.
-Patient is instructed for the warm saline rinses at home and this should be done after each hour and if the condition is worst then the antibiotics are also prescribed.
-If the flap is found to be swollen then the incision is given on the part and then drainage of the exudate is the procedure for that.
Treatment of Pericoronitis also depends upon the condition of involved tooth, the extent of inflammation that has taken place and the decision whether to save the involved tooth or not.
