Internal bleaching procedures are performed on devitalized teeth that already had a root canal but are discoloured with time due to internal staining. Unlike external bleaching, which brightens teeth from the outside in, internal bleaching brightens teeth from the inside out. Bleaching the tooth internally involves drilling a hole to the pulp chamber where the nerve use to be before the root canal. This hole is more precisely done through the filling that was sealing the root canal. The dentist then proceds to clean the publ chamber, apply the whitening agent, and then make a new filling to seal the tooth.
