MAXILLARY TORUS Maxillary tori are common benign outgrowths of bone from the maxilla which may project both inwards or outwards from the alveolar bone. They are composed of compact bone which is densely mineralised and without a medullary cavity. The cause of such outgrowths has not been established but a genetic component is thought likely. Teeth grinding (bruxism) and people who clench their teeth might be more likely to develop it. They are usually asymptomatic but may cause issues with eating and drinking. Occasionally may suffered ulceration after traumatised by toothbrush during brushing. The size of the tori can increase slowly and continuously through the life of an individual, but because of benign and asymptomatic, do not require any specific management. However, surgical management may be necessary in case of prosthetic instability or pre-prosthetic surgery.
