What is a jaw cyst?
A jaw cyst is a fluid-filled cavity in the jawbone that usually grows slowly and often causes no symptoms at first. For this reason, many cysts are discovered incidentally during a dental X-ray examination. Depending on its location, however, a cyst can displace or weaken the surrounding bone. If left untreated, it can affect neighboring tooth roots, nerves, or other structures.
The most common causes are inflamed tooth roots, teeth that have not fully erupted, or developmental abnormalities during tooth formation.
