Abstract
A significant aspect of cosmetic dentistry is the treatment of tooth discoloration. Discoloration of non-vital anterior teeth can cause significant esthetic concern and requires efficient treatment. Discoloration of teeth can be extrinsic or intrinsic or a combination of both based on etiology, appearance, localization, and severity. Walking bleach involves the use of chemical substances like sodium perborate or hydrogen peroxide which in contact with the tooth release oxidizing agents that diffuse through the enamel and dentin and oxidize the pigments responsible for discoloration. This article aims at presenting a case series on the walking bleach method performed on discolored endodontically treated teeth associated with superior esthetic outcomes.
