What causes mandibular tori?

The exact etiology of mandibular tori is not fully understood, but there are several contributing factors:

Bone growth and development: Mandibular tori are bony growths that occur on the lingual surface of the mandible. They are thought to be caused by abnormal bone deposition during growth and development.

Genetic factors: There appears to be a genetic component to the formation of mandibular tori, as they tend to run in families. Certain genetic variations may influence bone growth and the formation of these bony growths.

Hormonal influences: Androgens, such as testosterone, have been implicated in the development of mandibular tori. Increased androgen levels may stimulate bone growth and contribute to the formation of these tori.

Local factors: Local irritation, such as trauma or chronic pressure from dentures or other dental appliances, may also contribute to the formation of mandibular tori. These factors can lead to reactive bone growth and the development of tori over time.

It's important to note that mandibular tori are usually asymptomatic and don't require treatment unless they cause functional problems or discomfort. If they do interfere with speech, chewing, or other oral functions, surgical removal may be considered.
