Do you have a painless lump in your jaw? Let's talk about this ameloblastoma!

Have you ever noticed a small, painless lump in your jaw, especially inside your mouth? Or have you ever had a dentist accidentally notice something unusual while examining your teeth and mention it? Sometimes we don't pay much attention to these things, but it's important to be aware of them. Today we're going to talk about a rare but important tumor that forms in the jaw. This is called ameloblastoma.

What is ameloblastoma? Let's understand exactly?

Simply put, an ameloblastoma is a tumor that develops in your jawbone, often slowly. It develops from the same cells that make the protective covering over your teeth, called tooth enamel. Isn't that surprising? About 80% of these tumors develop in the lower jaw, where your big back teeth (molars) are.

Now you may be thinking, "When you say a tumor, does it mean cancer?" Actually, ameloblastoma is often called a benign tumor. That means it is not cancer. However, there is a little thing to understand here. When we say "benign", we usually think "harmless, nothing to worry about." But with ameloblastoma, that is not the case. Although these tumors are not cancerous, they can gradually grow and change the shape of your jawbone and damage your teeth. Also, they can sometimes grow back (recur) even after treatment.

Therefore, even if this is not cancer, it is very important to diagnose it early, get the right treatment, and be monitored closely after treatment. Only then can damage to the jawbone be prevented.

Are there different types of ameloblastoma?

Yes, doctors look at these tumors under a microscope and classify them based on how the cells look. At first glance, these cells look like honeycombs or small, soapy particles. There are several main types:

• Conventional ameloblastoma: This is the most common type. It accounts for about 85% of all ameloblastomas. It grows a little faster than other types and is more likely to spread from the jawbone to the surrounding tissues of the mouth .
• Unicystic ameloblastoma: This type is less likely to spread beyond the jawbone than the conventional type.
• Peripheral (extraosseous) ameloblastoma: Researchers think these often spread from the gums or soft tissues of the mouth to the jaw. They grow more slowly than the other two types.

Although very rare, some ameloblastoma tumors can become cancerous (malignant). There are two types:

• Metastasizing ameloblastoma: These tumors look like `benign` tumors under a microscope. But they are actually `metastatic cancer`. A doctor may only find out that it is `metastatic` after the cancer has spread to other parts of the body, such as the lungs, brain, or skin.
• Ameloblastic carcinoma: This tumor can start as a cancer from the beginning. Or, it can start as a benign ameloblastoma and then become cancerous.

How common is this condition called ameloblastoma?

Ameloblastoma is one of the most common benign tumors of the jaw, but overall it is very rare. Studies have shown that only about one in a million people are diagnosed with the disease each year. Of those, only about 2% have malignant ameloblastoma.

Although this condition can develop at any age, it is most common in people between the ages of 30 and 60. It is also said that this disease is more commonly diagnosed in African and Asian countries.

What are the symptoms of Ameloblastoma?

Because these tumors grow slowly, you may not have any symptoms for 10 to 20 years. You or your doctor may not notice it until much later. It is only when the tumor grows and invades surrounding tissue that you may experience changes in the shape of your face and jaw or problems with your teeth.

These are some of the common symptoms:

• A painless swelling in the jaw area. This often affects only one side of the face.
• It's like a new growth that's pressed into the inside of the cheek, like a peanut or a small ball.
• Pink or red spots on the teeth, or teeth that break easily.
• Difficulty moving the jaw.
• Gums become red and swollen.
• Teeth not fitting together properly (malocclusion).
• Teeth grinding.

Why does ameloblastoma develop? What are the causes?

These tumors develop because the cells that make your tooth enamel (called ameloblasts) continue to grow after your tooth enamel has formed. Experts don't yet know exactly why this happens.

However, recent studies have found that many people with ameloblastoma have common genetic mutations that are linked to problems with cell division and help the tumor grow. In particular, mutations in the genes BRAF and SMO are commonly associated with ameloblastoma.

Experts are currently researching these genetic changes to identify targeted therapies that will specifically target and destroy the problematic cells.

How do doctors diagnose ameloblastoma?

When you go to the dentist for a routine check-up, X-rays may show signs of ameloblastoma. If so, your dentist will refer you to a specialist for further tests. These tests may include:

• Imaging tests: Other tests, such as X-rays, MRI (Magnetic Resonance Imaging - MRI), and CT scan, may be done to see exactly where the tumor is and how big it is. These tests can also help your doctor rule out other types of tumors that look similar to ameloblastoma. If it is cancerous, a Positron Emission Tomography (PET scan) may be done to see if it has spread to other parts of the body.
• Biopsy: A biopsy allows your doctor to take a small piece of tissue from the tumor and have it examined under a microscope by a pathologist. The type of cells will help your doctor determine exactly what type of ameloblastoma it is and decide on the best treatment.

What are the treatments for Ameloblastoma?

The best treatment for ameloblastoma is surgery to remove the tumor and some of the surrounding tissue (so that no abnormal cells remain). Doctors divide surgeries for these tumors into two main types:

• Radical surgery: This is a major surgery for people with ameloblastoma. Here, the doctor removes a large amount of the jawbone and surrounding tissue along with the tumor. This is to reduce the risk of the tumor coming back. It may also remove part or all of the lower jaw (mandibulectomy) or part or all of the upper jaw (maxillectomy).
• Conservative surgery: Here, the doctor removes the tumor along with a small amount of healthy tissue and bone. This minor surgery may be done if your tumor is small and has little chance of spreading to surrounding bone and tissue.

If you are not a good candidate for surgery, your doctor may recommend radiation therapy to destroy the tumor. Or, they may recommend radiation therapy to destroy any remaining tumor cells after surgery. This treatment uses high-energy X-rays to destroy the cells.

Additional treatments that may be needed after surgery

Major surgery for ameloblastoma can take a long time to heal, usually several months. After that, you may need additional treatments to get back to normal. For example:

• Reconstructive surgery: You will work with a plastic surgeon to restore the appearance of your face and jaw. This surgery involves taking bone from another part of your body (such as your hip or shoulder) and rebuilding the jaw area.
• Dental implants: These are artificial teeth (prosthetics) that replace the teeth that were removed during surgery. These can help you regain the ability to chew properly and restore your confidence in the appearance of your mouth.
• Speech therapy: A speech-language pathologist can help you adjust to changes in your jaw and face so you can chew, swallow, and speak properly.
• Nutritional advice: A dietitian can help you choose nutritious foods that are easy to chew and swallow during your recovery.

Can the risk of developing ameloblastoma be reduced?

There is no way to prevent this. However, seeing a dentist at least once every six months for a dental check-up and getting oral cancer screenings can help detect these growths early. Early treatment can help prevent ameloblastoma from damaging your jaw and facial tissues.

If I have this condition, what should I expect?

Your prognosis depends on your health, the type of ameloblastoma, its location, and the type of surgery performed to remove the tumor.

Many people who have been treated for ameloblastoma will need lifelong monitoring to see if the tumor will come back. This is because about 20% of people will develop the tumor again after surgery. More than half of the time, the tumor will come back within the first five years after surgery.

Therefore, ask your doctor how often you should have tests to see if the tumor is growing back.

What happens if ameloblastoma is left untreated?

If left untreated, ameloblastoma can damage important parts of your face and jaw, and can sometimes be fatal. If left unchecked, these tumors can disfigure your face, make it difficult to chew and swallow. If they grow further, they can invade the tissues of your brain and central nervous system, and block your airways.

Therefore, treatment for ameloblastoma can prevent these most severe conditions from occurring.

When should I see my doctor?

You should know exactly how often you need to come in for follow-up visits to check for recurrence after treatment. Unfortunately, many ameloblastomas can recur years after surgery. If they do, your doctor can recommend new treatments to prevent further damage to your jaw and face.

When should I go to the emergency room?

Your doctor will tell you what to expect as you recover from surgery. However, you should go to the emergency room right away if you have any of the following:

• If you have a fever over 101 Fahrenheit (38.3 Celsius).
• If you have pain that does not subside even after taking the painkillers prescribed by the doctor.
• If there is more pus or swelling from the wound than you expected.
• If you have difficulty breathing or feel like you are suffocating.

What questions should I ask my doctor?

Ameloblastoma is a serious medical condition that requires major surgery. Here are some questions you can ask as you and your doctor discuss treatment:

• What kind of surgery do I need to have?
• Why do you recommend that surgery?
• Will other treatments be needed besides surgery to completely remove the tumor?
• Will I need plastic surgery or speech therapy?
• What are the possible complications or side effects?
• What is the chance that this ameloblastoma will recur?

Final Take-Home Message

When we hear the word `benign`, we think ``harmless.`` But with ameloblastoma, it's not that simple. If left untreated, these tumors can damage your jaw and facial parts. But, remember, there are treatments that can control these growths. Ask your doctor about the type of surgery that he or she recommends based on the type of tumor and your health. Your doctor is the best person to explain to you what the best treatment is to remove the tumor and preserve as much healthy tissue in your jaw as possible. So, don't be afraid to ask him or her questions, and get everything explained. Stay healthy!
