Gum swelling after root canal treatment?


Hello: It has been 7 days since my root canal treatment, but the gums around that tooth are still swollen.
There is no pain, but I feel a dull sensation when biting down.
After the root canal, the dentist's X-ray showed no shadows, indicating it was perfect.
Is the wound still healing? Generally, how long should I observe this, and how long is it normal for the swelling to last before returning to normal? Should I consider switching clinics? Thank you very much.

Hello: It is recommended to continue monitoring at the original clinic for about 1 to 3 months.
If discomfort persists, then consider seeking a second opinion from the Endodontics department at a medical center.

More Info


After undergoing root canal treatment, it is not uncommon to experience some degree of gum swelling, especially in the days following the procedure. In your case, since it has been seven days post-treatment and you are still noticing swelling in the gums around the treated tooth, it is essential to understand the potential reasons for this and what to expect moving forward.

Firstly, it is important to recognize that root canal treatment involves the cleaning and sealing of the tooth's interior, which can sometimes lead to inflammation in the surrounding tissues. This inflammation can manifest as swelling in the gums, even if there is no pain associated with it. The fact that you are experiencing a "dull" sensation when biting down suggests that there may still be some residual inflammation or sensitivity in the area, which is not unusual.

The absence of any shadows on the X-ray taken by your dentist indicates that there are no visible signs of infection or complications at this time, which is a positive sign. However, the healing process can vary significantly from person to person. In general, it can take anywhere from a few days to several weeks for the tissues to fully heal after a root canal procedure. During this time, it is normal for some swelling to persist, especially if the area was particularly inflamed prior to treatment.

As for how long you should observe the swelling, it is advisable to monitor the situation for another week or so. If the swelling does not begin to decrease or if you start to experience pain, increased swelling, or any other concerning symptoms, it would be prudent to return to your dentist for a follow-up examination. They may want to take another X-ray or perform a clinical evaluation to ensure that everything is healing as expected.

In terms of whether you should consider changing dental practices, this decision should be based on your overall comfort and trust in your current dentist. If you feel that your concerns are not being adequately addressed or if you are not satisfied with the level of care you are receiving, seeking a second opinion from another dental professional can be beneficial. However, if your dentist has been responsive and thorough in their evaluations, it may be worth continuing to work with them through the healing process.

In summary, while some gum swelling after root canal treatment can be normal, it is essential to keep an eye on it. If the swelling persists beyond a reasonable timeframe or if you develop new symptoms, do not hesitate to reach out to your dentist for further evaluation. Healing can take time, and open communication with your dental care provider is key to ensuring a successful recovery.
