Maxillary tori

Maxillary tori are analogous to mandibular tori and are composed of densely mineralised bone usually devoid of a medullary cavity. Unlike in the mandible, where they arise on the inner surface, when arising from the maxilla they may project both inwards (in which case they arise from the midline of the hard palate, known as torus palatinus, or inner surface of the alveolar bone) or outwards (from the alveolar bone). 

The cause of such bony outgrowths has not been established but has been linked to genetics.

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


Bony outgrowths can be well appreciated 

  • from the alveolar bone (inner or outer)
  • from midline hard palate (inward protrusion into the oral cavity, known as torus palatinus)
