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.
