Is Tori genetic?

Published in Oral Health 3 mins read

Yes, tori appear to have a significant genetic component, suggesting a hereditary predisposition for their development.

Understanding Tori: Bony Growths in the Mouth

Tori are benign bony outgrowths that can develop in the mouth. While generally harmless, they are a common anatomical variation. These growths are typically found in two main areas:

  • Torus palatinus: Located on the roof of the mouth (palate).
  • Torus mandibularis: Found on the inner side of the lower jaw (mandible), often near the tongue.

Tori can manifest in various ways. You might have just a single torus, or they can appear in groups of different shapes and sizes. Their presence doesn't usually cause discomfort unless they interfere with speech, eating, denture placement, or become irritated.

The Genetic Link to Tori

Research strongly indicates that genetics play a crucial role in the formation of tori. If one or both of your parents have tori, you are more likely to develop them as well. This suggests an inherited trait, making them a common feature that often runs in families.

While genetics are a primary factor, other elements such as environmental influences or functional stress (like bruxism or teeth grinding) are sometimes considered as contributing factors, though their exact impact compared to genetic predisposition is still an area of study.

Prevalence and Demographics

The occurrence of tori can vary among different populations and sexes:

  • Overall Tori: Generally, tori are observed more frequently among males than females.
  • Palatal Tori (Torus Palatinus): Interestingly, palatal tori are twice as likely to occur in women compared to men, showing a specific sex-linked prevalence for this type.
  • Mandibular Tori (Torus Mandibularis): These are more often found in men and in certain ethnic groups.

Characteristics of Tori

Tori can be:

  • Size: Ranging from small bumps to larger, lobulated masses.
  • Shape: Smooth, nodular, lobular, or spindle-shaped.
  • Number: Single or multiple growths.
  • Growth: They tend to grow slowly over time and can increase in size, especially during middle age.

When to Seek Professional Advice

Most tori do not require treatment. However, consulting a dentist is advisable if tori:

  • Interfere with oral hygiene: Making it difficult to clean teeth or gums.
  • Cause discomfort: Especially when eating certain foods.
  • Impede dental procedures: Such as fitting dentures or other prosthetics.
  • Change rapidly in size or appearance: Though rare, this warrants evaluation.
Type of Torus Location Common Demographics
Torus Palatinus Roof of the mouth (palate) Twice as likely to occur in women than men
Torus Mandibularis Inner lower jaw (mandible) More common in men and certain ethnic populations
