Managing discoloured non-vital teeth: the inside/outside bleaching technique.

ABSTRACT

The discoloured, non-vital anterior tooth is a common aesthetic concern for many patients. It can have a profound effect on their self-esteem, interaction with others and employability. Discoloured non-vital teeth are frequently compromised owing to previous trauma, caries, endodontic therapy and failed restorations. Destructive invasive treatment options are likely to weaken the residual structure of the tooth. This can reduce the prognosis and challenge the long-term viability of the tooth, thereby initiating further prosthetic predicaments. This paper discusses modern approaches to the treatment of discoloured teeth. The importance of preventing and eliminating the potential for discoloration will be highlighted. The paper will include a detailed technical account on the application of the inside/outside bleaching technique, with several clinical examples.
