Understand

A jaw cyst is an abnormal cavity, often lined by epithelium and containing fluid or material, within the upper or lower jaw.

Possible symptoms

Many are found on an X-ray; swelling, pain, infection, tooth displacement, numbness or drainage can develop.

Causes and associated factors

They may arise from tooth development, dental infection or, less often, other tissues; a cyst-like image alone does not identify its nature.

Diagnosis

Diagnosis combines dental context, examination and imaging; laboratory examination of a biopsy or removed lesion usually confirms the type.

Tests

Panoramic X-ray, CBCT or CT maps the lesion; tooth vitality tests, aspiration and biopsy are selected case by case.

Course of the condition

Some remain small; others enlarge, weaken bone, move teeth, recur or resemble a tumour, which is why follow-up matters.

Care options

Treating a dental cause, observing selected cases, decompression, marsupialisation or surgical removal depends on type, size and nearby structures.

When to consult

Seek assessment for an incidental image, swelling, tooth movement, numbness or recurrent infection.

Urgent help

Rapid swelling, fever, limited mouth opening, difficulty swallowing or breathing, or a fracture after minor trauma needs urgent assessment.

Questions for your doctor

  • What exact diagnosis and extent have been established?
  • Which functions—breathing, vision, chewing, speech or swallowing—are affected?
  • Which non-surgical and surgical options should we compare?
  • Which nerve, dental, functional and appearance risks should I consider?
  • What multidisciplinary follow-up will be needed?
