Retained tooth root
The abnormal present of a tooth root without an associated crown. This may be observed covered by gingival and found on radiographs, or penetrating the gingival following inadequate extraction or loss of crown after trauma or resorption. Radiographs are mandatory to determine the degree of pathology.
A self resorbing root causing no obvious inflammation or pain may be monitored, whereas a partially erupted root demonstrating gingival inflammation and pain should be extracted.
