The main cause of dental abscesses is untreated tooth decay, which is often invaded by bacteria. This is referred to as deep decay: an advanced lesion of the tooth that reaches the inner layers. However, dental abscesses can be caused by other factors such as:
- dental trauma
- an infection in a wisdom tooth
- a periapical abscess: an infection that forms at the root of the tooth
- A periodontal abscess: an infection of the supporting tissues around the tooth that leads to bacterial spread and pus accumulation.
The appearance of an abscess is often due to fear of visiting the dentist. It is necessary to react quickly when a dental abscess appears, before the inflammation turns into an emergency. This is because it can lead to severe complications, such as sepsis.
The abscess may be the result of periodontal disease, untreated chronic periodontitis, or treatment for chronic periodontitis. It may be caused by a foreign body in the periodontal pocket or damage to the root, promoting the presence of bacteria and the formation of a pocket of pus. Treatment must be prompt and comprehensive in order to address the causes of the abscess and prevent more serious complications.
