If a tooth becomes severely discolored, but all of the other adjacent teeth appear normal, we can bleach just that individual tooth!
This is called internal bleaching, and the goal is for that tooth to achieve a similar shade to those teeth surrounding it. After the root canal is completed, a bleaching material is placed within the tooth and left there for a period of time.
The amount of time depends on how discolored your tooth was and how white you desire it to become. The endodontist checks its progress every week or two and replenishes the bleach as needed. Once the desired brightness has been achieved, the bleach is removed and a permanent filling is placed.
