Your dentist took an X-ray and found a cyst in your jaw. The word sounds alarming. Is it cancer? Does it need to be removed? Let us explain what a dental cyst actually is and how it is treated.

A dental cyst is a fluid-filled sac that forms in the jawbone or soft tissues of the mouth. It develops from epithelial cells that are left behind after tooth development. These cells form a closed pocket, and the pocket slowly fills with fluid or soft material.

Cysts are generally slow-growing. They often cause no pain at all, which is why they are usually discovered on routine X-rays. Unless they are quite large, you probably will not even know they are there.

The word cyst sounds frightening, but the vast majority of dental cysts are benign. They are not cancerous. That said, they do need to be assessed and monitored or treated because of the effects they can have on surrounding structures.

The most common type is a radicular cyst, which forms at the root tip of a tooth that has died or has a large filling. These are associated with infected or non-vital teeth and are usually benign.

A dentigerous cyst forms around the crown of an unerupted tooth, most commonly around wisdom teeth or canine teeth. These can grow quite large and may cause bone expansion if left untreated.

An odontogenic keratocyst is a more aggressive type that originates from dental tissue. These can be more challenging to treat because they tend to grow aggressively and have a higher chance of recurring after removal.

Your dentist or oral surgeon will determine which type of cyst you have based on its location, appearance on X-ray, and sometimes a biopsy.

In most cases, a small dental cyst is not immediately dangerous. But it is not something to ignore either.

As a cyst grows, it can pressure surrounding teeth and cause them to shift or loosen. It can cause bone loss in the jaw. Very large cysts can even cause a pathological fracture of the jawbone in extreme cases.

If a cyst becomes infected, it can turn into an abscess, causing pain, swelling, and potentially fever. This needs prompt treatment with antibiotics and drainage.

In extremely rare cases, a cyst can undergo malignant transformation, meaning it becomes a cancer. This is exceptionally uncommon but is another reason why cysts should be properly assessed.

Most cysts are found on routine X-rays. They appear as well-defined circular or oval areas of darkness in the jawbone. Your dentist will assess the size, location, and appearance.

A CT scan or CBCT scan might be needed for larger cysts to see exactly how much bone is affected and to plan treatment. A biopsy may be taken to confirm the diagnosis, especially for atypical-looking lesions.

Treatment depends on the size and type of cyst. Small, asymptomatic cysts are sometimes just monitored with regular X-rays to check they are not growing.

Most cysts are treated with surgical removal. The procedure is called enucleation, where the dentist or oral surgeon removes the entire cyst sac. If the associated tooth is not salvageable, it may be extracted at the same time.

For larger or more aggressive cysts, a procedure called marsupialisation might be used. This involves creating an opening in the cyst and suturing the edges to the oral mucosa so the cavity can drain and shrink over time.

After removal, the tissue is usually sent to a laboratory for analysis to confirm the diagnosis and rule out any atypical or malignant features.

Recovery from cyst removal is generally straightforward. You may have some swelling and discomfort for a few days, which can be managed with pain relief and ice packs.

You will need to eat soft foods for a week or two while the site heals. Your dentist will give you specific aftercare instructions, including how to keep the area clean.

Stitches, if used, are usually dissolvable and disappear on their own. You will have a follow-up appointment to check that healing is progressing normally.
