What is a torus palatinus?

The hard palate, or roof, of the mouth is slightly rounded and usually smooth. However, some people may have a hard lump or protrusion extending out of this area.

This lump, called a torus palatinus, may develop over time. In other cases, a person may have it their entire life.

Tori palatini are common, affecting around 20–30% of people in the United States. They appear to be more common in women and in people of Asian or Inuit descent.

However, doctors do not understand what causes them or why they are more common in some groups than in others.

Tori palatini are usually harmless. They will not usually require treatment unless they interfere with a person’s speech, ability to swallow, or daily life.

However, removal may be necessary before the fabrication of a denture. In that case, a dentist may recommend surgery to remove the growth or changing the shape of the dental device to fit around the growth.

Tori palatini are not dangerous. The growths do not cause cancer, infections, or other serious complications. However, like any growth in the body, it can interfere with normal functioning.

A person should see a doctor or dentist for any unusual growths in the mouth. Even if it looks like a torus palatinus, it is important to rule out other potential causes.

Developing a torus palatinus can potentially be alarming, especially to someone anxious about oral health or cancer. However, these growths are benign, which means that they do not cause cancer and are not a risk factor for cancer.

As long as they do not cause significant symptoms, a person does not need to treat them.

However, because new growths in the mouth could warn of a more serious health concern, it is important to consult a doctor rather than self-diagnose.
