What is odontoma?

Odontoma is a specific type of tumor that is benign and located in your mouth. It is made of all or some of the tissues that make your teeth. However, these tissues may or may not be arranged in the form of a tooth.

Odontoma may not be visible to the naked eye.  It is a mass of enamel, dentin, pulp and cementum that usually grows at the same rate as teeth. However, this mass is disorganized and any one of the components may become the dominant part.

How common is odontoma?

Odontomas are thought to be the second most frequent type of odontogenic tumor worldwide, accounting for about 20% of all cases.

Odontoma is most often found in people around age 14 as a tooth that has not emerged. More complex odontoma are found in males up to age 30. Though more recent data indicates these tumors are found in both genders.

However, it can be managed by reducing your risk factors. Please discuss with your doctor for further information.


What are the symptoms of odontoma?

There are many symptoms of odontoma but they are often overlooked or misdiagnosed. One that is serious is difficulty with swallowing. (dysphagia).  If a tooth is delayed when it ought to be erupting, that is another sign that something is not right. If you have a lump in your gum, that could be a symptom of odontoma.  Some may be confused initially with an impacted wisdom tooth.

You could also have a primary tooth that is not coming out as it should. Also, if the bone beneath your tooth is enlarged, your dentist will notice this as a possible sign of odontoma. These are some reasons why you need to keep a good connection with your dentist. That way the dentist becomes familiar with your teeth and oral conditions.

When should I see my doctor?

Early diagnosis and treatment can stop odontoma from worsening and prevent another medical emergency, so talk to your doctor as soon as possible to prevent this serious condition.

If you have any signs or symptoms listed above or have any questions, please consulting with your doctor. Everyone’s body acts differently. It is always best to discuss with your doctor what is best for your situation.


What causes odontoma?

No one knows for sure exactly why odontoma occurs but some feel that it could be from an infection and/or trauma to the site. Some dentists believe they develop because of genetic mutation or they are hereditary. One example of an inherited syndrome that might cause odontoma is Gardener Syndrome. This syndrome is responsible for a range of tumors in the body, including odontoma occasionally.

How is odontoma diagnosed?

Odontoma does not usually show external symptoms. These tumors are revealed when the x-rays are examined by the dentist. Although it is true that a delayed tooth or absent tooth may suggest there is a need for further examination.

The presence of a tumor of dental origin requires further examination to determine what type of tumor it is before further action is taken. In addition, a histological diagnosis of the tissues that were extracted provides valuable information to the dentist.

  • Odontoma histology: No one really knows why an odontoma forms. The most likely reasons are trauma and/or infection at the site. Some dentists and researchers believe they are hereditary or they develop because of genetic mutations. One example of an inherited syndrome is known as Gardener Syndrome. It is responsible for a wide range of tumors in the body, including occasional odontoma. When examined at the cellular level, all of the dental tissues are found, but in an abnormal combination.
  • CT-scan for odontoma: CT-scan refers to the images found by x-rays enhanced by computer tomography (a layered sectional view). These advanced technological images help the dentist see what is inside the tumor before engaging in surgery to remove it.  They are each unique in formation and each arrangement of dental tissue can determine what kind of structure it has. Sometimes a complex odontoma can extend into the nasal cavity and require special attention. It is important to perform a complete examination beyond a simple x-ray to obtain this additional information.  Sometimes magnetic imaging is recommended (MRI) to gain a thorough analysis of a complex mass.

How is odontoma treated?                      

The only real treatment of these dental tumors is removal by surgery. An early discovery and treatment will be beneficial to the patient. It is a benign tumor made of dental tissue and it is a fairly simple extraction in most cases. A speedy recovery is generally expected. Some complex tumors can result in complications after extraction. So it is essential to stay in contact with your surgeon.
