Persistent Discomfort After Root Canal and Post: What to Do? - Dentistry

Share to:

Root canal treatment has been performed, and a post has been placed, but discomfort (pain) persists?


Hello: I underwent root canal treatment for a lower right first molar in January of this year, and I have since had a post placed, but I have not yet received a crown.
Since the treatment began six months ago, I have experienced discomfort (not painful to pressure, but there is a dull, achy sensation when tapping the tooth side to side).
X-rays show no abnormalities, and the dentist suggested that sensitivity in the adjacent teeth might be the cause.
I sought a second opinion and had another X-ray taken, which also showed no issues.
I was hoping that the discomfort would gradually improve over time, but since yesterday, I have been experiencing significant pain, feeling as if the entire lower right quadrant is hurting.
Drinking hot or cold beverages exacerbates the pain.
I would like to ask the doctor how I should address this issue.
Thank you very much.

Hello, based on the above situation, a tooth that has undergone root canal treatment should not experience pain.
However, if there is currently pain, please visit a hospital or dental clinic for treatment.
Wishing you safety and health.
Sincerely, Dr.

More Info


Persistent discomfort after a root canal treatment can be quite distressing, especially when it evolves into significant pain. Based on your description, it seems that you have been experiencing discomfort for several months following the procedure, and now you are facing acute pain that worsens with temperature changes. Here are some insights and recommendations based on your situation.


Understanding Post-Root Canal Discomfort
1. Normal Healing Process: After a root canal, it is not uncommon to experience some discomfort as the tissues around the tooth heal. This discomfort can last for a few days to a few weeks. However, persistent discomfort lasting several months is not typical and warrants further investigation.

2. Possible Causes of Persistent Discomfort:
- Residual Infection: Sometimes, bacteria can remain in the tooth or surrounding tissues, leading to an infection that may not be visible on X-rays. This could explain the ongoing discomfort and the sudden onset of acute pain.

- Pulpitis: If the pulp tissue was not completely removed or if there is inflammation in the remaining pulp, it can cause sensitivity and pain.

- Periapical Abscess: An abscess can form at the root tip, which might not always be visible on standard X-rays, especially in the early stages.

- Sensitivity of Adjacent Teeth: As your dentist mentioned, sensitivity in adjacent teeth can also contribute to discomfort, particularly if they are under stress from the root canal tooth.

3. Symptoms of Concern: The sudden increase in pain, especially with temperature sensitivity, is concerning. It may indicate that the situation has worsened, possibly due to an infection or other complications.


Recommendations for Management
1. Consult Your Dentist: Given the escalation of your symptoms, it is crucial to return to your dentist or an endodontist (a specialist in root canal treatments) as soon as possible. They may need to conduct a thorough examination, possibly including advanced imaging techniques like a cone beam CT scan, to assess the situation more accurately.

2. Pain Management: In the meantime, over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage your discomfort. However, avoid using them as a long-term solution without addressing the underlying issue.

3. Avoid Triggering Foods: Since you mentioned that cold and hot drinks exacerbate the pain, it would be wise to avoid these until you can see your dentist. Stick to lukewarm foods and drinks to minimize discomfort.

4. Consider a Second Opinion: If you feel that your concerns are not being adequately addressed, seeking a second opinion from another dental professional may provide additional insights or treatment options.

5. Follow-Up Treatment: Depending on the findings, your dentist may recommend retreatment of the root canal, additional procedures to address any infection, or possibly even extraction if the tooth cannot be salvaged.


Conclusion
Persistent discomfort following a root canal treatment is not something to ignore, especially when it escalates to acute pain. It's essential to seek professional dental care promptly to diagnose and treat the underlying issue effectively. Trust in your dental care provider, but also advocate for your health by ensuring that your concerns are heard and addressed. Your comfort and well-being are paramount, and timely intervention can often lead to a better outcome.
