Causes of tooth abscess

A periapical tooth abscess occurs when bacteria invade the dental pulp. The pulp is the innermost part of the tooth that contains blood vessels, nerves and connective tissue. Bacteria enter through either a dental cavity or a chip or crack in the tooth and spread all the way down to the root. The bacterial infection can cause swelling and inflammation at the tip of the root.
