Management

Acute pericoronitis – The area underneath the operculum is gently irrigated to remove debris and inflammatory exudate. Often warm saline is used but other solutions may contain hydrogen peroxide, chlorhexidine or other antiseptics.

Definitive treatment – 

Oral hygiene – Pericoronitis can be treated with maintaining good oral hygiene if debris is not much in the coronal region,there is no need of extraction of tooth

Operculectomy – It includes surgical removal of operculum. Remove the part of tissue which is coming to pinch in between the two opposing tooth.

Tooth Extraction- In severe cases where above treatments not works at optimum level,patients are advise for extraction of wisdom tooth.extraction eliminates any further episodes of pericoronitis.
