A – Z of Illnesses & Conditions

Abscesses: An abscess is a collection of pus in any part of the body that causes swelling and inflammation around it.  Abscesses occur when an area of tissue becomes infected and the body's immune system tries to fight it.  White blood cells move through the walls of the blood vessels into the area of the infection and collect in the damaged tissue. During this process, pus forms. Pus is the buildup of fluid, living and dead white blood cells, dead tissue and bacteria or other foreign substances.

Abscesses can form in almost any part of the body. The skin, under the skin, and the teeth are the most common sites. Abscesses may be caused by bacteria, parasites and foreign substances. Abscesses in the skin are easy to see. They are red, raised, and painful. Abscesses in other areas of the body may not be seen, but they may cause organ damage.

Brush and Floss Daily: To keep your teeth and gums healthy, you need to floss and brush them every day. But even with the best of care, you can still develop dental problems, including a tooth infection called an abscess. Bacterial infection of the tooth causes pus to become trapped underneath. An abscessed tooth is typically the result of untreated tooth decay but can also occur after a broken tooth or lost filling.

See your doctor if you think you may have an abscess. An infected tooth should be treated by your dentist to save the tooth.
