Safe, Expert Dental Cyst Removal, From £140

What Is Dental Cyst Removal?

A dental cyst is a fluid-filled sac that forms in the jawbone, usually at the tip of a dead or infected tooth root. Cysts can also develop around impacted teeth (such as wisdom teeth) or from other dental infections. They grow slowly and are usually detected on an X-ray or panoramic scan.

Dental cyst removal (cystectomy) is a minor surgical procedure where your oral surgeon opens the gum tissue, carefully removes the entire cyst and its lining, and cleans the surrounding bone. If the cyst was caused by an infected tooth, the tooth may also need treatment, either a root canal or an extraction, depending on how much damage has occurred.

The procedure is carried out under local anaesthesia and typically takes 30 to 60 minutes. The cyst is sent for laboratory analysis to confirm it is benign (non-cancerous), which it is in the vast majority of cases.

Without treatment, dental cysts can continue to grow, weakening the jawbone, damaging adjacent teeth, and increasing the risk of infection. Early removal is straightforward and prevents these complications.

Am I a Good Candidate?

Dental cyst removal may be recommended if you have:

• A cyst detected on an X-ray or panoramic scan during a routine dental check-up
• Swelling or tenderness in the jaw that your dentist suspects may be caused by a cyst
• A history of tooth infection or root canal treatment, where a cyst has formed at the root tip
• An impacted wisdom tooth with an associated cyst (dentigerous cyst)
• A cyst that is growing and needs to be removed before it causes further damage to bone or neighbouring teeth

Your dentist or oral surgeon reviews your scans and clinical examination to determine the best approach. In some cases, a smaller cyst may be monitored rather than immediately removed. Your surgeon discusses the options with you and explains the reasoning behind their recommendation.

What Happens During Your Treatment?

The Procedure (30-60 Minutes)

Your oral surgeon administers local anaesthesia to numb the area completely. A small incision is made in the gum to access the cyst. The cyst is carefully separated from the surrounding bone and removed in its entirety, including the cyst lining, this is important to prevent recurrence. If an infected tooth root is the cause, it may be treated or extracted at the same time.

The area is cleaned thoroughly and the gum is closed with dissolvable stitches. A bone graft material may be placed in the cavity if the cyst was large, to help the bone regenerate.

After the Procedure

You can return to your hotel or home the same day. You are given aftercare instructions, prescribed antibiotics and pain relief, and advised on what to eat during the healing period. The removed cyst is sent to a laboratory for analysis, results are typically available within a few days.

Recovery and Aftercare

Recovery from dental cyst removal is manageable and most patients feel significantly better within the first week.

Days 1-2: Expect some swelling and mild discomfort around the surgical site. This is normal and managed with prescribed pain relief and cold compresses. Stick to soft, cool foods and avoid the surgical side when chewing. Do not use straws, as the suction can disturb the healing site.

Days 3-5: Swelling begins to subside. Discomfort reduces noticeably. You can gradually introduce warmer, softer foods. Continue taking prescribed antibiotics as directed, even if you feel fine.

Week 1-2: Most patients feel largely back to normal. Dissolvable stitches begin to dissolve on their own. Avoid hard, crunchy, or very hot foods until your surgeon confirms the site is healing well.

Weeks 4-8: The soft tissue heals fully. Bone regeneration in the cavity left by the cyst continues over the following months, particularly if a bone graft was placed.

Long-term: The site is monitored with follow-up X-rays to confirm the bone is regenerating and the cyst has not recurred. Recurrence after complete removal is uncommon.

Risks and Considerations

Dental cyst removal is a routine oral surgery procedure with a good safety record. As with any surgery, there are risks to be aware of.

Infection: A small risk of post-operative infection exists, minimised by prescribed antibiotics and good aftercare. Contact your dental team if you develop fever, increasing pain, or discharge from the surgical site.

Nerve damage: If the cyst is located near a nerve (particularly the inferior alveolar nerve in the lower jaw), there is a small risk of temporary numbness or tingling in the lip, chin, or tongue. This is rare and usually temporary, resolving within weeks to months.

Recurrence: If the cyst lining is completely removed, recurrence is uncommon. Your surgeon takes care to ensure the entire lining is excised. Follow-up X-rays monitor the site.

Tooth loss: If the cyst has caused significant damage to an adjacent tooth, that tooth may not be salvageable and may need to be extracted. Your surgeon discusses this possibility before the procedure.

Jawbone weakness: Large cysts can thin the jawbone. In rare cases, the bone may be temporarily weakened after cyst removal. Bone grafting during the procedure helps mitigate this.
