A torus palatinus or mandibular torus is a benign bony growth that develops on the hard palate (roof of the mouth) or the lingual surface (tongue side) of the mandible (lower jaw). These are common, painless, and usually asymptomatic bony growths that don't require treatment unless they cause problems with dentures or other oral functions.
What Causes Tori to Develop in the Mouth?
The exact cause of tori formation isn't fully understood, but several factors are believed to contribute:
- Genetics: A strong genetic predisposition is the most significant factor. If someone in your family has tori, you're more likely to develop them.
- Mechanical Stress: Some theories suggest that constant pressure or friction from teeth grinding (bruxism) or chewing habits might stimulate bone growth.
- Hormonal Influences: Fluctuations in hormone levels, particularly estrogen, are thought to play a role, especially in women. This is supported by the higher prevalence of tori in women.
It's important to understand that tori are not tumors or cancerous growths. They are simply benign bony overgrowths.
What Do Tori Look Like?
Tori can vary significantly in size, shape, and appearance. They can be small and barely noticeable, or large and quite prominent. Typically, they are:
- Hard and bony: They feel like a hard, bony growth.
- Sessile or pedunculated: They can be flat and broad-based (sessile) or have a stalk-like connection to the bone (pedunculated), though the sessile type is more common.
- Smooth or lobulated: The surface can be smooth or have multiple lobes.
- Color of normal bone: They usually match the color of surrounding bone tissue (pale pink or whitish).
Are Tori Painful?
Generally, tori are painless. They rarely cause discomfort unless they become irritated or injured, or interfere with other oral functions.
What Happens If Tori are Injured?
Trauma to a torus can cause pain, bleeding, and ulceration. Gentle handling and avoiding hard foods can usually resolve this.
When Should I See a Dentist About Tori?
Most people with tori don't need treatment. However, you should consult your dentist if:
- They interfere with dentures: Tori can make it difficult to fit or wear dentures comfortably.
- They cause pain or discomfort: Any unusual pain or discomfort should be evaluated.
- They become ulcerated or infected: Injury or infection needs prompt dental care.
- You have concerns about their appearance: While cosmetic concerns are less common, you can discuss options with your dentist.
What Treatments Are Available for Tori?
Surgical removal is the primary treatment if necessary, often done for denture fitting issues or persistent discomfort. The procedure is typically straightforward and minimally invasive.
Can Tori Be Prevented?
There's no proven way to prevent tori development, given their strong genetic component. Maintaining good oral hygiene is always beneficial for overall oral health.
Are Tori Cancerous?
No, tori are not cancerous and pose no health risk beyond potential interference with dentures or the occasional injury. They are simply benign bony overgrowths.
