K04: Diseases of pulp and periapical tissues
K04.6: Periapical abscess with sinus
Every tooth consists of 3 sections: the crown, the tooth neck (cervix) and the tooth root. The crown is the visible part of the tooth. The tooth neck is covered by the gums. The tooth root keeps the tooth in the jawbone. The tooth is anchored firmly in the jawbone by the periodontal ligament. This ligament includes, among other things, the outermost layer of the tooth root and the gums. The periodontal ligament also includes the hole in the jawbone in which the tooth is located.
In your case, the periodontal ligament has become inflamed at the bottom of the tooth root. Your periodontal ligament has become inflamed, because the inside of the tooth was inflamed. The inflammation has spread from the tooth to the periodontal ligament.
Because of the inflammation, pus has accumulated at the bottom of the tooth root. Among other things, pus is composed of dead tissue and pathogens. The pus accumulation is connected to the mouth via a duct.
If pus accumulates in the periodontal ligament, you may have a severe toothache, for example. Your cheek may also swell up.
