Root Canal Treatment: When to Seek Urgent Dental Care - Dentistry

Root canal treatment


Hello, Doctor.
I would like to ask about my situation.
I had my upper right seventh permanent tooth extracted on August 25, and on September 7, I underwent root canal treatment on my lower right fourth permanent tooth.
After the procedure, it was only temporarily filled with a material, and I am scheduled to return for further filling treatment on September 26.
However, on the evening of September 8, I started to feel a tingling and pressure sensation in the tooth that underwent root canal treatment.
By the morning of September 9, the pain became more pronounced, and my face is slightly swollen.
Pressing on the gums near the root canal area causes pain.
I have been taking acetaminophen and ibuprofen for pain relief, but it only lasts about 3-4 hours.
Since there is still some time before my follow-up appointment, I would like to know if this is serious.
Should I contact the office to arrange an earlier appointment? Thank you, Doctor.

Hello: It is recommended to call the clinic first and inform them about the persistent swelling and pain, as well as the quick diminishing effect of the pain medication.
Inquire if it is possible to arrange an earlier examination to check for any bacterial infection at the extraction site.

More Info


It sounds like you're experiencing some concerning symptoms following your recent dental procedures, particularly after the root canal treatment on September 7. The symptoms you describe—pain, swelling, and sensitivity—can indicate a few potential issues that may require urgent attention.

Firstly, it’s important to understand that after a root canal treatment, some discomfort is normal as the area heals. However, the increasing pain and swelling you're experiencing could suggest that there is an infection or inflammation in the area. The fact that you are feeling a "sour" or "pulsating" sensation, along with facial swelling, is particularly noteworthy. These symptoms can be signs of an abscess or a failure of the root canal treatment, where bacteria may still be present in the root canal system.

Given that you are currently managing your pain with acetaminophen and ibuprofen, and that the relief lasts only a few hours, it is crucial to monitor your symptoms closely. If the pain intensifies or if you develop additional symptoms such as fever, increased swelling, or drainage from the gums, you should seek dental care immediately. These could be signs of a more serious infection that may require antibiotics or further intervention.

In your case, since you are experiencing significant discomfort and swelling, it would be advisable to contact your dentist or endodontist as soon as possible to discuss your symptoms. They may recommend an earlier appointment to evaluate the situation. It’s better to err on the side of caution, especially when it comes to dental health, as untreated infections can lead to more severe complications.

In the meantime, continue taking your pain medication as directed, and consider using a cold compress on the outside of your cheek to help reduce swelling. Avoid any hard or crunchy foods that could exacerbate your discomfort, and maintain good oral hygiene to prevent further irritation.

In summary, while some discomfort is expected after dental procedures, the symptoms you are experiencing warrant a prompt evaluation by your dental care provider. Early intervention can prevent complications and ensure that your treatment proceeds smoothly. Don’t hesitate to reach out to your dentist for guidance; they are there to help you through this process.
