A: Signs and symptoms of a failed root canal treatment (RCT) are usually what prompted you to seek treatment in the first place. They include tenderness or swelling of the gums surrounding the tooth, pain when biting, pus or abscess near the tooth and/or a shaky tooth.
Immediately after a root canal treatment, it is normal for the surrounding area to be tender or sore. Hence, there is no cause for alarm during this period. The discomfort should go away eventually. However, if the discomfort persists or the pain returns after the tooth had recovered previously, you are advised to visit your dentist/endodontist so that they can carry out a thorough check for you.
Causes of a failed root canal treatment
A treated tooth may fail
due to bacteria remaining in the root canal or bacteria re-entering
the tooth after treatment. These can be caused by:
- A filling that is defective and leaking or a crown that has dislodged
- A cracked tooth
- Gum disease or tooth decay
- Presence of persistent bacteria remaining in the root canal which may be impossible to eradicate due to the complexity of the root canal system
Therefore, it is important
to take good care of your treated tooth. Patients are encouraged to
brush at least twice a day, for at least two minutes each. It is also
advisable to visit your dentist two times a year and floss daily.

Thanks for the post. The frequently asked questions that you have discussed are very useful and must to know thing. I have taken root canal treatment last year with the coverage of stand alone dental discount plans VA. I got 50% discount on my treatment expense.
