Acute periapical periodontitis

Acute periapical periodontitis is when the apical section of the root of a tooth and the supporting structure surrounding it, becomes infected and inflamed.


The bacteria in the oral cavity cause decay. It damages and destroys the inner soft centre of the tooth – the pulp. The pulp of the tooth dies and this requires a rapid periodontal disease treatment. Failure to do so may increase the infection. Because after the pulp infection, root canal infection will follow. This will result in periodontitis.

Besides infection, trauma or a direct blow to a tooth can cause acute periapical periodontitis. Upon this, the pulp of the tooth dies and the bacteria in the gum tissues start infecting the tooth to its roots. A hard blow, a bite attempt of a hard object, application of unwanted pressure or force during dental treatments, can all lead to acute periapical periodontitis.

Another cause of acute periapical periodontitis can be the root canal therapy UK. Root canal treatment also has the potential to cause inflammation in the periapical area.
