Post-Root Canal Treatment Issues


I have a molar that underwent root canal treatment at Clinic A.
At that time, I reported to the dentist that the tooth had a noticeable percussion pain, but the dentist said the treatment was completed and that I should return for a crown.
However, if the tooth still has percussion pain, wouldn't it still hurt after getting the crown? Therefore, I have not returned to Clinic A.
I left it alone for four months, and the tooth is still in the same condition.
Since I wanted to get a crown, I went to Clinic B and also mentioned the tooth issue.
However, the dentist reviewed the X-rays and said they couldn't see any problems and suggested I return to my original clinic for better evaluation.
But Clinic A initially said there was no issue.
After reading many articles online, I feel like I might need another root canal, which has a high failure rate.
Bacteria are not visible to the naked eye, and I feel that returning to Clinic A would yield the same results.
So now I'm unsure what to do.
Should I make an appointment at a hospital, or is it better to go back to Clinic A? Both clinics have a waiting time of over a month, and I am already feeling exhausted from the ongoing discomfort in my tooth.

Hello: If you have doubts about the treatment plan from the physician at Clinic A, it is advisable to request a referral to the endodontics department at a medical center for evaluation.
This will help determine if there are any other issues related to the root canal and whether re-treatment is necessary.
If three or more physicians inform you that there are no problems with the root canal, you should further investigate to identify any other potential causes of the pain!

Dealing with persistent tooth pain after a root canal treatment can be quite frustrating and concerning. It’s important to understand that while root canal therapy is designed to alleviate pain caused by infection or damage to the tooth's pulp, some patients may experience discomfort even after the procedure. This discomfort can arise from several factors, and addressing it requires a careful approach.

First, it’s essential to recognize that some level of discomfort can be expected after a root canal, especially if the tooth was severely infected or inflamed prior to treatment. The inflammation may take some time to subside, and during this period, you might experience sensations like pressure, sensitivity to biting, or a dull ache. However, if the pain persists for an extended period, or if it worsens, it may indicate that further intervention is needed.

In your case, you mentioned experiencing a "knocking pain" after the initial treatment, which raises a few possibilities. One common issue is that the root canal may not have fully cleared all the infected tissue or bacteria. If the canals were not adequately cleaned or if there are additional canals that were missed, this could lead to ongoing pain. Additionally, the presence of a periapical abscess (infection at the tip of the root) could also be a reason for the persistent discomfort.

You also expressed concern about the effectiveness of the treatment and the possibility of needing a retreatment. It’s important to note that while retreatment can be successful, it does come with its own risks and challenges. The success rate of retreatment is generally high, but it depends on various factors, including the complexity of the root canal system and the presence of any additional complications.

Given your situation, here are some steps you can take:
1. Seek a Second Opinion: Since you’ve already visited two different dental offices, it might be beneficial to consult with an endodontist (a specialist in root canal treatment). They can provide a more detailed examination, possibly including advanced imaging techniques like a cone beam CT scan, which can reveal issues that standard X-rays might miss.

2. Discuss Symptoms Thoroughly: When you visit a new dentist or specialist, be sure to communicate all your symptoms clearly. Describe the nature of the pain, when it occurs, and any other relevant details. This information can help the dentist make a more accurate diagnosis.

3. Consider Temporary Solutions: While waiting for your appointment, you can manage pain with over-the-counter medications like ibuprofen or acetaminophen. However, be cautious about prolonged use and consult with a healthcare provider if you have any concerns about side effects or interactions with other medications.

4. Evaluate Treatment Options: If retreatment is recommended, discuss the potential outcomes and risks with your dentist. They should explain the procedure, what to expect, and the likelihood of success based on your specific case.

5. Follow Up on Recommendations: If your current dentist suggests returning to the original clinic, weigh the pros and cons. If you feel uncomfortable with their assessment, it’s perfectly reasonable to seek care elsewhere.

6. Maintain Oral Hygiene: Continue to practice good oral hygiene, as this can help prevent further complications. Regular brushing, flossing, and avoiding overly hard or sticky foods can minimize discomfort.

In conclusion, persistent pain after a root canal treatment is not uncommon, but it should not be ignored. Seeking a thorough evaluation from a dental specialist can provide clarity and guide you toward the appropriate treatment. Remember, your comfort and health are paramount, and it’s essential to advocate for your needs in your dental care journey.
