Teeth whitening is a common cosmetic procedure to improve coloring. Teeth that have undergone a root canal procedure require special care and treatment to protect the remaining tooth structure.
Consult with your endodontist about which treatment option is best for you.
Walking bleach technique: The filler in the root canal is removed. A bleaching gel is inserted into the space and sealed with a temporary filling. After a few days, the gel is removed and the root canal filler is replaced.
Inside/outside bleach technique: This exposes the interior and exterior of the tooth to a bleaching agent. The filler of the root canal is removed. A bleaching gel is inserted in a splint attached to adjacent teeth. The splint is worn at night. You will be responsible for cleaning the tooth and putting the splint on each night. When the tooth is the right color, the cavity is cleaned and the root canal filler is replaced.
In-office bleaching technique: Often used for bleaching teeth that have not had an endodontic treatment, your teeth will be coated by a bleaching gel in a rubber dam that is inserted in your mouth for 15 to 20 minutes. The gel is then rinsed off and repeated if needed. This treatment offers the quickest results, but results are temporary.
