Cysts in the jaw are caused by infections at the apex of  teeth whose nerves have died. Other causes are retained or impacted teeth.
Cysts are liquid – filled cavities in the jawbone which grow,  weakening the bone but not necessarily causing pain. Their removal is always indicated. They are most often detected by change during x-ray examination.
Small cysts can be removed easily and the bone regenerates itself. Larger cavities caused by cysts are filled with bone or bone regeneration material ( link to ‘ Plasma’ in the menu ). After removal of cysts the gum is closed by suture.
