A dental cyst is a pathological cavity, usually fluid-filled, that forms at or around a tooth root. It typically arises as a result of infection, trauma, or developmental anomalies. Dental cysts generally grow slowly and may not produce symptoms in the early stages.
Dental cysts may be asymptomatic initially. However, as they enlarge, the following signs and symptoms may appear:
-
Swelling or tenderness of the gum
-
Tooth pain or jaw pain
-
Loosening or displacement of teeth
-
Thinning or deformation of the jawbone
-
Formation of an intraoral fistula or unpleasant taste
Causes of dental cyst formation may include:
-
Infection or necrosis of the dental pulp
-
Impacted teeth (particularly third molars)
-
Damage to tooth roots following trauma
-
Developmental anomalies or genetic factors
Dental cysts are often detected during routine dental radiographs. Imaging methods such as panoramic radiography and cone beam computed tomography (CBCT) may be used for a definitive diagnosis. If necessary, a biopsy can be performed to determine the type of cyst.
Treatment depends on the size, location, and type of the cyst. Common treatment approaches include:
-
Curettage: surgical removal of the cyst
-
Apical resection: removal of the root tip of the affected tooth together with the cyst
-
Marsupialisation: opening the cyst into the oral cavity to reduce the size of larger cysts
-
Tooth extraction: extraction of the affected tooth may be necessary
Untreated dental cysts may enlarge over time, leading to damage to the jawbone, tooth loss, infections, and, in rare cases, tumour development from the cyst. Early diagnosis and treatment are therefore important.
Mild pain, swelling, and discomfort may occur following surgery. These symptoms usually subside within a few days. The full recovery period varies depending on the size and location of the cyst, but generally takes several weeks.
Because local anaesthesia is administered during surgery, pain is not felt during the procedure. Mild to moderate pain may occur postoperatively; however, this can usually be managed with prescribed analgesics.
Cysts that are not completely removed or left untreated may recur. Regular follow-up appointments and additional treatment where necessary are therefore important.
