A cyst is a closed, abnormal sac of tissue within your body containing fluid or soft materials. They most commonly occur in your jaw bone than in any other bone in your body. You may develop a cyst in your jaw due to many reasons, for example from:
- Infection from a broken or bad tooth.
- Inflammation at the root of a tooth containing a dead/non-vital pulp
- Gum inflammation over erupting teeth, like the wisdom teeth
- Cells and fibres surrounding a developing tooth
- Inherited condition (e.g. Gorlin-Goltz syndrome)
