Procedure Method
With non-vital tooth whitening, how much the tooth brightens depends on the degree of discoloration and its response to whitening, so the final color is difficult to predict precisely.
If needed, regular teeth whitening can be done at the same time to reduce the color difference from the neighboring teeth.
Tooth Discoloration After Root Canal Treatment
Teeth that have had root canal treatment can turn gray or brown over time.
01Blood components
Blood components remaining inside the tooth can contribute to discoloration.
02Breakdown products of tissue
Breakdown products of tissue inside the tooth can cause color changes.
03Previous treatment materials
Some root canal materials can also cause tooth discoloration.
Treatment Candidates
When a single front tooth has darkened after root canal treatment
When one particular tooth looks gray or brown compared with the others
When a tooth has become discolored after trauma
Whether non-vital tooth whitening is possible is decided after checking the condition of the root canal treatment, the extent of damage and the cause of discoloration.
Non-Vital Tooth Whitening Process
01 Checking the tooth and the cause of discoloration
We check the tooth color, the degree of discoloration and the condition of the existing root canal treatment.
02 Internal whitening
After checking the inside of the tooth and taking the necessary protective measures, the whitening agent is placed and the tooth is temporarily sealed.
03 Replacing the agent and checking the color
We check the change in tooth color and replace the whitening agent as needed.
The number of sessions may vary depending on the tooth's condition and its response to whitening.04 Final restoration and completion
After the whitening process, the inside of the tooth is restored at the appropriate time to complete treatment.

Frequently Asked Questions
Discoloration that starts inside the tooth may not improve enough with regular teeth whitening alone. In such cases, non-vital tooth whitening, which applies a whitening agent inside the tooth, can be considered.
Non-vital tooth whitening is generally performed on teeth that have had root canal treatment. Even if a tooth has become discolored from trauma or similar causes, the nerve may still be alive, so the tooth's condition and the cause of discoloration must be checked first.
Non-vital tooth whitening can be considered even if the root canal treatment was done long ago. However, whether it is possible and the expected result depend on the condition of the previous root canal treatment, the extent of tooth damage and the cause of discoloration.
Unlike crowns or laminates, non-vital tooth whitening does not involve removing the entire outer surface of the tooth. The whitening agent is generally applied inside the tooth through the existing root canal access, and some additional treatment may be needed depending on the tooth's condition and existing restorations.
A whitening agent is placed inside the tooth, and the color change is checked after a set period. Depending on the degree of discoloration and how the tooth responds to whitening, it may be carried out several times.
A tooth that has completed root canal treatment has no sensation inside, so the whitening process is generally not very painful. However, some discomfort may occur depending on the condition of the tissues around the tooth, and any symptoms should be checked.
It is difficult to predict exactly how much brighter the tooth will become after non-vital tooth whitening. A color difference from the neighboring teeth may remain, and regular teeth whitening can be done at the same time if needed.
It depends on how damaged the tooth is. If enough tooth structure remains, color improvement can be attempted with whitening, but if the tooth is badly damaged or at risk of fracture, a separate restoration such as a crown may be needed.
Yes. The tooth may darken again over time. Whether and when it becomes discolored again varies with the tooth's condition and the cause of discoloration, and retreatment can be considered if needed.
In rare cases, complications such as root resorption, in which part of the tooth root is resorbed, may occur. To reduce this risk, we check the condition of the root canal treatment and take appropriate protective measures so that the whitening agent does not seep toward the root.
