Internal, or non-vital, bleaching is used to lighten a darkly
discolored tooth that has had root
canal therapy. A chemical oxidizing agent is placed within
the coronal portion of a tooth to remove tooth discoloration.
It may be performed in the dental office using a procedure
known as "chair side bleach." In this procedure,
bleach crystals are placed inside the tooth, left for a period
of time, and then removed before leaving the office. This
may be done once or several times, depending upon the discoloration
of the tooth. Another method is known as "walking bleach".
In this procedure, bleach crystals are placed inside the tooth,
left for several days and then the patient returns to the
dental office to have the bleach crystals removed. Again,
this procedure may be performed one or more times, depending
upon the discoloration of the tooth.
