There may be extreme
examples of single tooth discoloration following trauma. But not all
these teeth can be treated successfully with Internal Bleaching.
Many require crowns or veneers. After a root
canal treatment is successfully completed, the pulp chamber
sealed with a temporary filling. This leads to a loss of aesthetics
in the anterior region. Internal bleaching (also
called Non-Vital Bleaching) is the answer for this
problem. The healing process is watched and the hollowed out crown
of the tooth is then filled with a bleaching paste or crystals, as
the case may be, and then sealed with a temporary filling.
An opening is made in the devitalized tooth from the rear. After
applying a special bleaching agent, the opening made in the rear
is then sealed with a temporary filling. The bleaching paste/crystals
is replaced every week until the desired lightness is achieved.
The bleaching paste/crystals and temporary filling are then removed
and a permanent restoration placed.
In another procedure is the chair side bleach. A chemical oxidizing
agent is placed within the hollowed out crown. It is left for a period
of time and then removed before leaving the office. Similarly, this
procedure may be performed one or more times. The picture is example
of tooth successfully treated with internal, non-vital bleaching.
