  The nerve can also die as we grow old, which makes the teeth, as a whole become yellow. So how does bleaching come in? let me cite you the process before: “It was discovered about 100 years ago that these teeth could be lightened up substantially by temporarily sealing up a cotton pellet soaked with oxalic acid inside the access hole in the crown of the root canal treated tooth. The cotton pellet was removed after several days and the access was sealed with a filling. Hydrogen peroxide may have been used to lighten teeth as early as 1884. In 1917, the process was speeded up using hydrogen peroxide and a heat lamp.” This procedure is still done in some clinics in the world.
