Abscessed Tooth
 |  | | Oral cancer is the sixth most common cancer, and accounts for about 3.6 percent of all cancers diagnosed, with roughly 40,000 new cases of oral cancer reported annually in the United States. The vast majority of oral cancers occur in people older than 45 years, with men being twice as likely as women to develop the disease. |

| An abscessed tooth is one that has become infected. Tooth decay is often the culprit; when tooth decay advances deep into the tooth, it can cause destruction of the pulp, the core of the tooth. When this happens, the pulp gets infected and swollen and pus builds up near the jawbone.
Left untreated, infected pulp can cause more serious problems, including damage to surrounding tissue and bone.
Root canal treatment is the most common form of treatment for an abscessed tooth. Root canal treatment involves removing the infected tissue, cleansing and sealing the canal of the tooth and restoring the tooth with a crown, or cap.
