Bleaching of non-vital teeth is a cosmetic dental procedure used to whiten teeth that have become discolored following root canal treatment. After a root canal, teeth may become dark due to the breakdown of pulp tissue inside the tooth.

The bleaching process involves placing a bleaching agent inside the tooth and sealing it temporarily. The agent helps to lighten the discoloration, and after a period of time, the dentist removes the material and places a permanent filling.

Non-vital tooth bleaching provides a way to restore the natural appearance of a tooth that has lost its color due to endodontic treatment, improving both function and aesthetics.
