What Is Torus Palatinus? A Common Bony Growth in the Mouth

Torus palatinus is a common, benign bony growth that can develop in the mouth. It is generally harmless and does not typically require intervention. Many individuals may not even be aware of its presence until it is discovered during a routine dental examination. This anatomical variation is not a disease or tumor.

What is Torus Palatinus?

Torus palatinus is a bony protrusion located on the hard palate, the roof of the mouth. This growth is typically found along the midline and is composed of dense, normal bone tissue. It presents as a hard, non-movable lump or ridge, covered by a thin layer of oral mucosa. The size and shape can vary significantly, ranging from small, flat bumps to larger, lobulated masses.

While most palatal tori are less than 2 centimeters in diameter, their size can change throughout a person’s life. This condition is common, affecting an estimated 20% to 30% of the general population. It is considered a benign anatomical variation, meaning it is not cancerous and poses no direct threat to health. The growth is an overgrowth of compact bone, contributing to its firm and stable nature.

What Causes Torus Palatinus?

The development of torus palatinus is multifactorial, involving genetic and environmental influences. Genetic predisposition plays a significant role, as the condition often runs in families, suggesting an inherited tendency.

Beyond genetic factors, mechanical stress is another contributing element. Chronic teeth grinding or clenching, known as bruxism, can exert pressure on the bony structures of the mouth, potentially stimulating bone growth in the palate. Some studies also suggest a minor link to dietary factors, such as high calcium intake or consumption of certain fish rich in polyunsaturated fats and vitamin D. However, the precise causes are not fully understood, and environmental factors like mouth anatomy and increased bone mineral density are also considered risk factors.

When Does Torus Palatinus Need Attention?

In most instances, torus palatinus does not require treatment because it is a benign and asymptomatic growth. However, specific circumstances may warrant medical or dental attention, including potential surgical removal. One primary reason for intervention is if the growth interferes with the proper fitting or wearing of dental prostheses, such as dentures. A large torus can prevent dentures from seating correctly, leading to discomfort or instability.

Additionally, attention may be needed if the torus experiences chronic irritation or ulceration due to trauma from food or other objects. Significant growth that causes speech difficulties or impacts the normal positioning and movement of the tongue can also warrant evaluation. Surgical removal is a straightforward procedure typically performed under local anesthesia. It is generally reserved for cases where the torus causes functional problems or persistent discomfort rather than for cosmetic reasons.
