Mandibular torus

Last revised by Daniel J Bell on 22 Jun 2022

Mandibular tori (cf. maxillary tori) are common benign outgrowths of bone from the inner surface of the mandible and are usually bilateral.

They are usually asymptomatic but may cause issues with eating and drinking.

They are composed of compact bone, densely mineralised usually without medullary cavity, and arise from the inner surface of the mandible. 

The cause of such bony outgrowths has not been established but a genetic component is thought likely.

Bony outgrowths from the inner aspect of the alveolar bone of the mandible above the origin of the mylohyoid muscle.

Mandibular tori are benign, slow growing and non-invasive. Removal is required only if they are symptomatic.
