Hypercementosis is an idiopathic, non-neoplastic condition characterized by the excessive buildup of normal cementum (calcified tissue) on the roots of one or more teeth.[1] A thicker layer of cementum can give the tooth an enlarged appearance, which mainly occurs at the apex or apices of the tooth.

Can be caused by many things. A way to remember the causes is "PIG ON TAP"[2]

Local factors-

Systematic factors-

It may be one of the complications of Paget's disease of bone in the form of generalized hypercementosis.

It may also be a compensatory mechanism in response to attrition to increase occlusal tooth height.


It is experienced as an uncomfortable sensation in the tooth, followed by an aching pain.[3]

It may be noted on radiographs as a radiopaque (or lighter) mass at each root apex.


Such deposits form bulbous enlargements on the roots and may interfere with extractions, especially if adjacent teeth become fused (concrescence). It may also result in pulpal necrosis by blocking blood supply via the apical foramen.[4]
