Vital bleaching:
  žBleaching of vital teeth is indicated primarily for patients with generalized yellow, orange, or light brown extrinsic discoloration (including chlorhexidine staining), although it may be helpful in ameliorating mild cases of tetracycline-induced intrinsic discoloration and fluorosis.
 
Nonvital bleaching:
žNonvital bleaching is indicated for the treatment of teeth with discoloration secondary to pulpal degeneration. This technique involves placing a mixture of 30% hydrogen peroxide and sodium perborate into the pulp chamber for as long as 1 week.
