The abscess can occur at different areas near the tooth for different reasons. A periapical (per-e-AP-ih-kul) abscess occurs at the tip of the root. A periodontal (per-e-o-DON-tul) abscess occurs in the gums at the side of a tooth root. The information here is about periapical abscesses.</p> <p>A periapical tooth abscess usually occurs as a result of an untreated dental cavity, an injury or prior dental work. The resulting infection with irritation and swelling (inflammation) can cause an abscess at the tip of the root.</p> <p>Dentists will treat a tooth abscess by draining it and getting rid of the infection. They may be able to save your tooth with a root canal treatment. But in some cases the tooth may need to be pulled. Leaving a tooth abscess untreated can lead to serious, even life-threatening, complications.</p> <fig> <title>Periapical tooth abscess</title> <desc> <p>Bacteria can enter the innermost part of the tooth through either a deep cavity or a chip or crack in your tooth.

To do this, your dentist drills down into your tooth, removes the diseased central tissue (pulp) and drains the abscess. The dentist then fills and seals the tooth's pulp chamber and root canals. The tooth may be capped with a crown to make it stronger, especially if this is a back tooth.
