Dentoalveolar abscess also known as dental abscess is an acute lesion characterized by localisation of pus in the structures and that surround the tooth. It is formed because of regeneration of pulp.


Trauma-causes necrosis of pulp followed by infection.

Caries-dental caries can cause acute pulpitis and necrosis of pulp. The inflammatory exudate passes through the pulp to apical foramen to settle in the apical area.

Chemical Irritants-materials used for devitalizing the pulp through apical foramen and cause inflammation and can lead to abscess formation.

Deep periodontal pocket-the infection from deep periodontal pocket passes to apical region directly or through lymphatics cause inflammation.

During instrumentation of root canal-infected instruments may pass through apical foramen to priapical region.
