Fibroma

fy-BROH-muh IPA: /faɪˈbroʊ.mə/

A fibroma is a benign growth of fibrous tissue in the mouth, usually caused by chronic irritation or trauma.

Understanding 

Fibroma

A fibroma is a common benign lesion that develops in the soft tissues of the mouth as a response to repeated irritation or minor trauma. It is made up of dense fibrous connective tissue and often forms as the body's protective response to chronic injury, such as cheek biting or friction from dental appliances. Fibromas most commonly appear on the inner cheeks, lips, tongue, or along the bite line. They typically present as small, smooth, dome-shaped growths that are similar in color to surrounding tissue, although they may appear slightly lighter. These lesions usually grow slowly and remain stable in size. If the source of irritation continues, the fibroma may persist or gradually enlarge. While fibromas are not cancerous, they do not usually resolve on their own without removal of the irritation or the lesion itself.

Clinical Significance

Usually benign and stable, but can persist, enlarge, or become irritated with repeated trauma.

Common Causes

Chronic cheek or lip biting, irritation from dental appliances, sharp tooth edges, repetitive trauma, friction

Signs & Symptoms

Firm, smooth bump inside the mouth, similar color to surrounding tissue, painless, slow-growing, may become irritated if bitten

How It's Detected

Clinical exam, visual inspection, patient history of irritation, biopsy for confirmation when needed

Treatment Options

Monitoring, surgical removal, elimination of source of irritation, no treatment in stable asymptomatic cases

Benefits to Treatment

Removes lesion, prevents recurrence, improves comfort, confirms diagnosis, restores normal tissue contour

Prevention

Avoid cheek or lip biting, smooth sharp tooth edges, properly fit dental appliances, regular dental visits

Frequently Asked Questions

Q

Are fibromas cancerous?

No, fibromas are benign growths and are not cancerous. In many cases, they develop as a response to chronic irritation rather than abnormal cell growth. However, any persistent oral lesion should be evaluated to confirm the diagnosis and rule out other conditions.

Q

Do fibromas go away on their own?

Fibromas typically do not go away on their own. In many cases, they remain stable unless removed or unless the source of irritation is eliminated. If the lesion is frequently irritated, it may persist or slowly increase in size over time.

Q

What is the most common treatment for a fibroma?

The most common treatment is simple surgical removal of the lesion. This is often a minor procedure and allows for confirmation of the diagnosis through evaluation of the tissue. Removing the source of irritation is also important to help prevent recurrence.

Q

Is a fibroma painful?

Fibromas are usually not painful. In many cases, they are discovered as a painless bump inside the mouth. However, they may become sore if they are repeatedly bitten or irritated during chewing.

Q

When should a fibroma be removed?

A fibroma may be removed if it causes discomfort, continues to grow, or interferes with function. In many cases, removal is also recommended to confirm the diagnosis. A dental professional can evaluate the lesion and determine the appropriate course of action.
