What Can You Do about Bony Growths in Your Mouth?
Posted on 7/1/2026 by South Valley Oral and Facial Surgery |
 Have you ever felt a hard, unusual bump in your mouth? It might be a bony growth. These growths are fairly common, and while they usually aren't dangerous, it's important to understand what they are, what causes them, and what, if anything, you should do about them.
What Are Bony Growths?
Bony growths in mouth, also known as exostoses or tori (singular: torus), are extra bone that forms in specific areas. They are typically hard, smooth, and covered by the normal tissue that lines your mouth. The most common locations are:
| • |
The roof of your mouth (torus palatinus): This growth appears in the middle of the hard palate. |
| • |
The lower jaw, on the tongue side (torus mandibularis): These growths usually occur near the premolars (the teeth between your canines and molars). |
These growths can vary in size. Some are small bumps, while others can be quite large and lobular (bumpy).
What Causes Bony Growths?
The exact cause isn't always known, but several factors are believed to contribute to their development:
| • |
Genetics: Bony growths often run in families, suggesting a hereditary component. |
| • |
Bruxism (teeth grinding or clenching): The pressure from grinding or clenching your teeth may stimulate bone growth. |
| • |
Diet: Some studies suggest that diets high in certain substances might play a role. |
| • |
Age: Bony growths tend to appear later in life and may slowly increase in size over time. |
When Should You Be Concerned?
In most cases, bony growths in mouth are harmless and don't require treatment. However, you should consult with a dental professional if:
| • |
The growth is rapidly increasing in size. This could indicate something other than a typical bony growth. |
| • |
The growth interferes with your ability to eat, speak, or swallow. Large growths can sometimes get in the way. |
| • |
The growth makes it difficult to maintain good oral care. If you can't properly brush and floss around the growth, it can increase your risk of gum disease and tooth decay. |
| • |
You need dentures or other restoration dentistry. Bony growths can sometimes interfere with the fit and comfort of dentures or other prosthetic appliances. If you are planning on getting dentures in the future, removal of the bony growth may be recommended to provide a better fit for the appliance. |
| • |
The overlying tissue becomes irritated or ulcerated. Chronic irritation can sometimes lead to sores or other problems. |
What Can Be Done?
If treatment is necessary, the most common approach is surgical removal of the bony growth. This is a relatively straightforward procedure, and most patients recover quickly. The removed bone is evaluated by a pathologist to confirm the diagnosis.
How Can You Prevent Bony Growths?
Unfortunately, there's no guaranteed way to prevent bony growths from forming. However, you can take steps to minimize your risk and manage any existing growths:
| • |
Practice good oral care. Brush and floss regularly to keep your mouth healthy and prevent inflammation. |
| • |
Manage bruxism. If you grind or clench your teeth, talk to your dentist about options such as a mouthguard. |
| • |
Regular dental checkups. Your dentist can monitor any bony growths and advise you on the best course of action. |
Bony growths in mouth are often a normal variation and not a cause for alarm. Understanding what they are and when to seek professional advice can help you maintain good oral health and peace of mind.
