K04: Diseases of pulp and periapical tissues
K04.5: Chronic apical periodontitis
Every tooth has a hollow interior. Connective tissue such as nerves and blood vessels is found inside a tooth. Through its interior, a tooth is formed and sustained.
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.
If the periodontal ligament is inflamed, the gums may bleed rapidly or appear red, for example. If the periodontal ligament is inflamed for a long time, the gums may retract from the tooth necks. The teeth may then also become loose. Sometimes small lumps also form in the gums as a result of the inflammation.
