After root canal treatment, this tooth turned dark. It was bleached from the inside out, over 3 separate visits to give a better appearance. Bleaching is unpredictable and sometimes the dark tooth refuses to lighten up. A composite resin veneer would be another option to cover the front of the tooth, and mask the darkness from the outside.
