What is internal bleaching?

Despite every effort, blood, bacteria, and saliva have the potential to enter a tooth during a root canal procedure.

As the bacteria and other contaminants break down within the tooth, they also darken. External bleaching won’t fix the problem because the discoloration is happening from the inside out.

So the answer is Internal bleaching, a minor surgical procedure that targets discoloration where it’s occurring in your tooth.

During the procedure, the tooth is isolated and cleaned. Then a rubber dam is placed on the tooth to prevent further contamination during the procedure, and discoloration in the future. An anesthetic cream is applied to your gums to ease discomfort.

Any decayed material that’s causing discoloration is removed. A bleaching agent is applied to the space within your tooth. This bleaching agent stays in your tooth for two to three days.

When the desired shade is reached, the bleaching agent is removed, and the tooth gets sealed. Some people may need an additional bleaching procedure if there’s notable discoloration.

This procedure is quite safe, but you may experience a little discomfort and tooth sensitivity following the procedure.
