A cyst is a sack or pouch which forms within tissues and contains fluid. This cyst is not cancerous growth. Cysts can develop in many places in the body. Around the face and mouth, they can develop under the skin, under the mouth lining, within the saliva glands, and within the jawbones.
There are different types of cysts within the jawbones.
- The commonest type is called a periapical cyst. These develop around the roots of teeth usually as a result of a chronic infection.
- Other cysts can develop around an uninterrupted tooth such as a wisdom tooth. These are called dentigerous cysts.
The final common group of jaw cysts develops from cells that form teeth. These are known as odontogenic cysts.
