What is a dental cyst?

Also known as odontogenic cysts, dental cysts are fluid-filled sacs that form in the jawbone or around the tooth root. They can develop during growth and are therefore most commonly seen in young people between the ages of 10 and 30. These types of cysts are rare in children. These cysts, which usually grow slowly, can also develop due to infection, trauma, or developmental problems.

Cysts are typically covered by soft tissue and can appear in various locations within the mouth, such as at the tip of a dead or decayed tooth root or around the crown of an unerupted tooth. These cysts are usually benign, meaning they are not cancerous. However, if left untreated, a tooth cyst can grow and cause bone loss, infection, and tooth loss. In most cases, tooth cysts are discovered by chance during routine X-rays because they do not usually cause symptoms in their early stages.

What causes tooth cysts?

Tooth cysts can usually occur due to infections or developmental problems in the jaw and teeth. However, cysts can also form for various other reasons. Understanding the underlying cause of the cyst can help determine the right treatment and prevent similar cysts from forming in the future.

Some of the most common causes of tooth cysts are listed below:

• Dead or dying tooth pulp: When the pulp inside the tooth becomes infected or dies, it can cause a periapical cyst to form at the tip of the root.
• Impacted or unerupted teeth: Cysts known as dentigerous cysts can form around the crowns of unerupted teeth, such as wisdom teeth.
• Developmental abnormalities: In some cases, cysts are associated with abnormalities in the tissues that form teeth during development.
• Trauma or injury: A blow to the mouth can damage the tooth or surrounding tissue, increasing the risk of cyst formation in the area.
• Genetic factors and syndromes: Some rare genetic conditions, such as Gorlin syndrome, can predispose an individual to developing multiple jaw cysts.

Understanding the factors that can cause tooth cysts is crucial in recognizing this issue and preventing potential cyst formation. However, it should be noted that not all cysts can be prevented. Nevertheless, regular oral hygiene and dental visits at specific intervals can prevent potential tooth cysts and prevent more serious problems from developing.

What are the symptoms of a tooth cyst?

Tooth cysts are often not noticed in the early stages because they grow slowly and do not immediately cause pain or discomfort. However, as the cyst grows, it can begin to affect the surrounding tissues in the mouth, leading to noticeable symptoms.

The common symptoms of a tooth cyst are as follows:

• Swelling or lump in the gums or jaw that can be seen from inside or outside the mouth
• Sensitivity, pain, or discomfort in the mouth when the area around the cyst is infected or there is pressure on the nerves
• Looseness and mobility of teeth due to the cyst weakening the surrounding bone
• Infection, pus in the mouth, bad breath, or a bad taste in the mouth due to bacteria entering the cyst
• Numbness and tingling in the lips, gums, or face, in rare cases, where large cysts put pressure on nerves

It is important to consult a dentist without delay if any of these symptoms are observed, especially if they are accompanied by swelling or pain in the face.

Can a tooth cyst turn into cancer?

We have mentioned that the vast majority of tooth cysts are benign. Therefore, we can say that the vast majority of tooth cysts do not pose a risk of turning into cancer. However, in very rare cases, certain types of cysts, especially if left untreated for a long time, may undergo changes. As a result of these changes, these cysts may, very rarely, develop into a tumor known as ameloblastoma or undergo malignant transformation.

It is important to emphasize that the risk of such transformation is very low. Most cysts do not develop into cancer during their growth and can be resolved through routine dental treatment or surgical removal. However, the key to minimizing potential risks is early diagnosis and treatment. Therefore, it is advisable to consult your dentist if you notice any such formations in your mouth. Your dentist will help you by performing regular dental checkups, including X-rays when necessary, monitoring any suspicious lesions, and intervening when necessary.

How are dental cysts treated?

The treatment of a dental cyst may vary depending on its size, location, type, and whether it causes any symptoms or complications. When treating a tooth cyst, dentists’ primary goal is to remove the cyst and prevent it from causing further damage to the surrounding teeth and bone. Therefore, dentists plan their treatment intending to preserve as much healthy tissue and bone as possible.

Treatment options may include:

• Root canal treatment: If the cyst originates from an infected tooth root (such as a periapical cyst), root canal treatment can eliminate the infection. Once the infection is eliminated, the cyst may shrink and heal over time.
• Surgical removal (enucleation): This method is used for medium and large cysts. The entire cyst is usually surgically removed under local anesthesia.
• Marsupialization: In some cases, the size of the cyst poses a high risk of damage to surrounding tissues during removal. In such cases, the cyst can be opened and drained using the marsupialization method to reduce its size, and then completely removed.
• Tooth extraction: If the affected tooth is severely damaged, it may need to be extracted along with the cyst.
• Follow-up and monitoring: After the cyst is removed, patients are usually monitored with periodic dental examinations and imaging to ensure that it does not recur.

Choosing the right treatment approach requires careful evaluation by a dentist or oral surgeon. In cases where the problem is detected early and the patient visits the dentist promptly, it is usually possible to complete treatment with simpler, less invasive solutions.

How is a tooth cyst surgery performed?

Dental cyst removal surgery, also known as cyst enucleation, is a safe dental procedure. The surgery is usually performed under local anesthesia, but sedation or general anesthesia may be used in more complex cases.

The procedure begins with an examination and imaging (usually an X-ray or CT scan) to determine the size and exact location of the cyst. After imaging, the patient is anesthetized, and the surgeon makes a small incision in the gum tissue to access the underlying cyst. The cyst is carefully separated from the surrounding bone and removed completely. In some cases, the cyst may be attached to a tooth. In such cases, the surgeon may decide that the tooth cannot be saved, and the tooth may need to be extracted.

In some cases, the surgeon may need to apply stitches to ensure proper healing of the tissue. Post-operative care typically involves avoiding hard foods and using prescribed antibiotics or mouthwash to prevent infection. Most people recover within a few days to a week, depending on the complexity of the surgery and their overall health.
