Dental fistula (/dɛntəl fɪs.tjuː.lə/) is a term used in dentistry to describe an abnormal communication between the oral cavity and the surrounding tissue. The word "dental" refers to teeth, while "fistula" describes the abnormal connection. The spelling of "fistula" might be confusing because of the silent "s" which is not pronounced in the IPA transcription. It is important to spell this term correctly to ensure proper communication between dentists and their patients, and to avoid confusion with other similar terms.
A dental fistula is an abnormal, narrow passageway that develops as a result of an infection or abscess in the mouth. It forms when the infection spreads from the tooth or gum tissue into the surrounding bone and tissues, creating a channel or tract for the pus to escape. The fistula typically appears as a small opening on the gum near the affected tooth, which may be accompanied by swelling, redness, and tenderness.
The dental fistula serves as a drainage route, allowing the accumulated pus to exit the infected area. It acts as a safety valve, preventing a build-up of pressure that could lead to more severe complications such as a spreading infection or an abscess. The pus that emerges from the fistula often has a foul smell or taste and may contain bacteria, dead tissue, and other debris.
Treatment of a dental fistula usually involves addressing the underlying infection. This may include a thorough cleaning of the affected tooth or gum, known as root canal therapy, to remove the infection and prevent its recurrence. In some cases, extraction of the affected tooth may be necessary if it is severely damaged or cannot be successfully treated. Antibiotics may also be prescribed to help combat the infection and promote healing.
If left untreated, a dental fistula can lead to further complications, such as the spread of infection to surrounding structures, the formation of larger abscesses, or damage to nearby teeth, bones, or nerves. Therefore, it is important to seek dental care promptly if any signs or symptoms of a dental fistula are present.

The term "dental fistula" originates from the fusion of two words: "dental" and "fistula".
1. Dental: The word "dental" is derived from the Latin word "dentis", which means "tooth". It entered the English language in the 18th century through the Latin term "dentalis", signifying anything related to teeth or dentistry.
2. Fistula: The word "fistula" has its roots in Latin as well. It comes from the Latin verb "findere", which means "to split" or "to cleave". In medieval Latin, "fistula" specifically referred to an abnormal, tubular passage or tract between two body cavities or organs.
