When your teeth are infected, this is called an odontogenic (tooth borne) abscess. When your gums are infected, it is known as a periodontal (gum related) abscess. Both are infections, but with different causes and outcomes. Odontogenic abscesses (tooth infections) happen when the nerve in one of your teeth dies. Once the nerve in a tooth dies, its natural resistance to invading germs is lost. This leaves a damp, dark environment where bacteria can feed and multiply freely. There are many causes for the nerve in one of your teeth to die. Breach of your tooth's nerve chamber by fracture or decay will kill it.
