Dens Invaginatus

 

Dens Invaginatus can occur in deciduous or in permanent teeth.  The coronal portion of the tooth folds inward and typically becomes non-vital.  The condition is also called "dens in dente" or a tooth within a tooth.  Non-vital teeth need to be treated by dental extraction or by root canal therapy.
