Chronic Apical Abscess

A chronic apical abscess is a slowly progressing infection at the tip of a tooth's root, which usually drains gradually and for that reason causes few symptoms or none during long periods.

How it shows up: It is often discreet; a small bump may appear on the gum that releases fluid, a bad taste in the mouth, or a mild, intermittent discomfort.

Common causes: It generally comes from a damaged or dead dental pulp that was not treated, maintaining a persistent infection in the root.

Which specialist treats it? The endodontist assesses the root and the interior of the tooth to identify the source of the infection. Even if it hurts little, it is best to have it reviewed with this professional, since a silent process also needs follow-up.
