Fifty‐eight bleached pulpless teeth were re‐examined after periods of 1–8 years. Recall examination included recording of the esthetic results, clinical findings and radiographs. External root resorption was found in 4 of the cases (6.9%), and was progressive in 2 cases and arrested in 2 cases. There had not been any pre‐ or postoperative trauma in any of the 4 cases. The occurrence of resorption was not related to the bleaching technique used. Resorptive lesions were found to have been initiated apical to and not at the cemento‐enamel junction. Esthetically, the bleaching was considered successful in only 50% of the cases, acceptable in 29% and failed in 21%. These results caution against indiscriminate use of bleaching with hydrogen peroxide, and emphasize the importance of preventive measures and postoperative follow‐up of bleached pulpless teeth.
