Clinical considerations for non-vital tooth walking bleaching


  • Danuchit Banomyong Department of Operative Dentistry and Endodontics, Faculty of Dentistry, Mahidol University


Root canal-treated teeth with coronal discoloration require esthetic improvement. The causes of discoloration should be evaluated for the proper treatment plan, and technical procedures of non-vital tooth bleaching should be carefully considered. Non-vital tooth walking bleaching is a simple, conservative, safe, effective, and low-cost procedure. This review article will focus on considerations in step-by-step for intracoronal ‘walking’ tooth bleaching to correct tooth discoloration after endodontic treatment. These important considerations are cleaned pulp chamber, appropriate level of gutta-percha, effective cervical seal, proper placement of bleaching agent, adequate temporary seal, and delay in permanent restoration.
