This chapter in “Textbook and Color Atlas of Traumatic Injuries to the teeth” focuses on the treatment of discolored traumatized teeth, most of them being non‐vital and subsequently, endodontically treated. Tooth bleaching based upon hydrogen peroxide as the active agent, applied directly or produced in a chemical reaction from sodium perborate or carbamide peroxide, must be regarded as the treatment of choice, alone or preceding a prosthetic restoration. More than 90% immediate success has been reported for intracoronal bleaching of non‐vital teeth, but in a period of 1–8 years after treatment, 10–40% of the initially successfully treated teeth needed retreatment.
