Bleaching of nonvital teeth: A review
Aurum Journal of Health Sciences. 2020;2(2):91-114.
ABSTRACT
The teeth frequently become discolored in time due to the endodontic treatment residues in the pulp chamber or hemolytic products accumulated in the dentine tubules after trauma. This condition may cause psychosocial problems for patients. Nonvital bleaching has gained popularity due to its conservative nature and low cost to overcome this unpleasant condition. This article will give an overview of nonvital bleaching techniques, materials and regimens used, bleaching procedure and side-effects.

STUDY SUMMARY
This narrative review addresses bleaching of nonvital teeth, which discolour over time from endodontic treatment residues in the pulp chamber or from haemolytic products in the dentinal tubules after trauma. It surveys the techniques, materials and regimens described in the literature, together with the bleaching procedure itself and its reported side effects. The article presents nonvital bleaching as a conservative and low-cost option rather than recommending a specific protocol.
