Dental abscess (Pediatrics - PEDS)

Low urgency
Common-
It is a collection of pus in the gums, secondary to a dental infection. The most common cause is tooth decay. It manifests with pain in one area of the mouth that coincides with chewing or with temperature changes when consuming food and drink. It can cause inflammation on one side of the face, inflamed lymph nodes and fever in more severe cases. It is diagnosed by closely inspecting the teeth, gums, mouth and neck. At first, painkillers will be administered to reduce the pain and antibiotic treatment to control the infection. At a later stage, a root canal treatment or dental extraction will be performed.
