Fibroma in Mouth: Causes, Symptoms, and Professional Treatment

If you have discovered a smooth, firm lump inside your cheek, lip, or tongue, you may be dealing with an oral fibroma. More professionals across the world trust Colgate. Find resources, products, and information to give your patients a healthier future. While finding any new growth in your mouth can be concerning, it is important to know that a fibroma in mouth tissue is typically a benign, noncancerous reaction to chronic irritation. Always seek the advice of your dentist or other qualified healthcare provider with any questions you may have regarding a medical condition or treatment.

What is an Oral Fibroma?

Fibromas are masses that can appear in other parts of the body but are commonly found in the oral cavity. An oral fibroma, often called an irritation fibroma or traumatic fibroma, is a mass of dense, fibrous connective tissue. Think of it as the body’s way of creating a “scar” in response to persistent trauma. Because these growths are composed of fibrous tissue, they are generally firm, smooth, and the same color as the surrounding oral mucosa, though they may appear white or dark red if they have been recently irritated. Clinical note: Unlike some other oral lesions, these fibromas are typically painless unless they become ulcerated due to secondary trauma.

Common Causes and Locations

The primary driver behind these growths is repetitive trauma. They most commonly appear on the tongue, inner cheeks, and lips, though they can grow on the outside of the mouth and have the potential to become raised. Common triggers include:

• Chronic Cheek or Lip Biting: Habitual biting of the same spot is a frequent cause.
• Dental Irritation: Rough edges on teeth, poorly fitting dentures, or dental appliances that rub against the soft tissue.
• Persistent Friction: Constant contact between a specific area of tissue and a sharp tooth or restoration.

While more common in adults, they can occur at any age. In rare instances, deeper fibromas can occur within the jawbone and are typically identified via digital imaging. Red flag: Any oral growth that rapidly changes in size, color, or texture, or that bleeds spontaneously without a clear history of trauma, should be evaluated by a professional immediately.

Diagnosis and Treatment

You may discover the mass yourself, or a dental or medical professional may find it during a routine examination. Because other lesions can mimic the appearance of a fibroma, a professional evaluation is essential to understand the anatomy of the area being examined.

Treatment Process

If the fibroma is causing discomfort or interfering with chewing, surgical removal is the standard treatment. This is typically a straightforward, minor procedure performed under local anesthesia by an oral maxillofacial surgeon or dentist. After the growth is removed, it is sent to a pathologist to ensure the tissue is benign. The recovery time is generally short, and most patients return to their normal routines quickly.

Important Cautions

While continuing your oral health routine is essential, do not attempt to brush the fibroma with your toothbrush, as this can cause further irritation. Additionally, never attempt to “pop” or remove a growth at home, as this can lead to infection or further tissue damage.

Preventing Future Fibromas

Because most oral fibromas develop from continual trauma or irritation, it is essential to identify and break the habits that caused the original growth. With the help of your dental professional, you can adopt preventive measures to keep your mouth wound-free.

Frequently Asked Questions

Are oral fibromas cancerous?

No, oral fibromas are almost always benign (noncancerous) growths. However, because they can look similar to other lesions, a professional biopsy is always recommended to confirm the diagnosis.

Can a fibroma in the mouth go away on its own?

Generally, no. Because they are composed of dense, scar-like tissue, they do not typically shrink or disappear without intervention. Removing the source of irritation may stop them from growing larger, but the existing mass usually remains.

Is the removal of an oral fibroma painful?

The procedure is performed under local anesthesia, so you should not feel pain during the removal. Most patients report only mild discomfort during the healing process, which is easily managed with over-the-counter pain relief.

Will a fibroma come back after removal?

There is a possibility of recurrence if the underlying cause—such as chronic lip biting or a sharp tooth edge—is not addressed. Your dentist will work with you to identify and eliminate the source of irritation.
