 An individuals quality of life can be seriously affected by the severity of dental pain. The emergency department is a common place to find those seeking relief from their dental pain- often times seeking removal of the affected tooth, dental anesthetic injections or oral pain medications. There are a number of dental infections that cause this type of debilitating pain. One such dental infection is termed periapical abscess. This infection involves the tooth pulp. These infections can arise in three ways: introduction through a defect in the enamel and dentin; from a periodontal pocket or an adjacent tooth; or hematogenous seeding of the pulp from mechanical irritation. As this disease process continues there are a number of complications including chronic pain and, more seriously, the spread of infection into deep spaces which can be a life threatening condition.
