Internal Teeth Bleaching

If you have had a root canal, chances are that tooth’s color does not match the rest of your teeth. A root canal removes the pulp of the tooth, which supplies the tooth with nutrients to keep it strong and healthy. Sometimes, a small portion of blood from pulp might stay in the top part of your tooth and/or mix with the root filling material, which can lead to discoloration. Dental trauma can also cause bleeding inside your tooth leading to internal stains. Whitening and external bleaching is a topical treatment that fades stains in the external part of your tooth but may not work on the stains originating from the inside of the tooth.
