If you have had a root canal on one of your front teeth, you may be concerned about the graying that can sometimes occur. In some cases, changing the temporary filling in the back with a permanent white filling is enough to eliminate this graying. However, if not, internal bleaching can be a great option to restore the luster to your teeth.
Internal bleaching is a procedure that uses peroxide to whiten teeth from the inside out. This is in contrast to traditional tooth whitening, which uses peroxide to whiten teeth from the outside in. Internal bleaching is typically used for teeth that have been discolored due to a root canal, trauma, or decay.
The procedure is relatively simple. The dentist will make a small hole in the back of the tooth and then place a bleaching agent inside. The bleaching agent will then diffuse through the tooth and break down the molecules that cause discoloration. The bleaching process can take several weeks, but the results can be dramatic.
It is important to note that internal bleaching is not a cure-all. It will not whiten teeth that are naturally dark or that have been discolored by heavy smoking or staining. However, it can be a very effective way to improve the appearance of teeth that have been discolored due to a root canal or other trauma.
Here are some of the risks and benefits of internal bleaching:
- Risks:
- Sensitivity to hot and cold temperatures
- Temporary tooth discoloration
- Gum irritation
- Root canal failure
- Benefits:
- Safe and effective procedure
- Can whiten teeth that have been discolored by a root canal
- Can improve the appearance of the smile

If you are considering internal bleaching, it is important to talk to your dentist. They can assess your teeth and determine if this is the right procedure for you. They can also answer any questions you have about the procedure and its risks and benefits.
Here are some additional things to know about internal tooth bleaching:
- Internal bleaching is typically done after a root canal has been completed.
- The dentist will take a dental x-ray to determine the extent of the discoloration and its cause.
- A dental dam will be used to isolate the tooth from further contamination during the bleaching procedure.
- If the tooth has not had a root canal, the dentist will remove the pulp and then place a whitening paste inside the tooth.
- If the tooth has had a root canal, a small hole will be made in the back of the tooth to gain access to the inside.
- Then a bleaching agent will be added inside the tooth and the hole will be carefully filled.
- The bleaching process can take several weeks, but the results can be dramatic.
- It is important to follow your dentist’s instructions after the procedure to ensure the best results.
