Root canal treatment


Hello Dr.
Liu,
I underwent two sessions of root canal treatment on my molars from mid-September to early November, and the canals have been filled.
However, when I apply pressure to the tooth, I still experience discomfort (which was the reason for the second root canal treatment).
It has been a month and a half, and the symptoms have not improved.
I had an X-ray taken at the clinic, but the dentist did not find any abnormalities.
Should I return to the original dentist who treated me, or should I seek a second opinion? Would waiting another two months for treatment be too long? What could be the issue with my tooth, considering I have already undergone two root canal treatments and had it filled? Is there still hope for my tooth?
Thank you for your assistance, Dr.
Liu!

Hello: Root canal treatment is a highly intricate procedure, especially for molars, which are more complex.
It is essential to completely clean, disinfect, shape, and densely fill the root canal system to ensure success.
If any of these steps are not performed properly, problems may arise.
If symptoms persist after root canal filling, it indicates that the treatment was not fully completed, and it is advisable to consult a specialist for re-treatment to increase the chances of success.
Sincerely, Dr.
Liu Tien-Tsai, Dentistry.

More Info


Persistent discomfort after root canal treatment can be a frustrating and concerning experience. It is important to understand that some level of discomfort can be normal following such procedures, especially if the treatment was complex or if there were multiple canals involved. However, if the discomfort persists for an extended period, as in your case, it may indicate that further evaluation and treatment are necessary.

Firstly, it is essential to consider the reasons behind the ongoing discomfort. After root canal therapy, the tooth may still be sensitive for a few days to weeks as the tissues around the tooth heal. This sensitivity can be exacerbated if the tooth was previously infected or if there was significant inflammation prior to treatment. However, if the discomfort has lasted for over a month and is not improving, it may suggest that there are underlying issues that need to be addressed.

One possibility is that there may be remaining infected tissue or bacteria within the root canal system that was not adequately cleaned during the initial treatments. This can occur, especially in cases where the canals are curved or have complex anatomy. In such situations, a retreatment may be necessary to thoroughly clean and disinfect the canals. Additionally, if there are any fractures in the tooth or if the filling material is not properly sealing the canals, this could also lead to persistent discomfort.

Another consideration is the possibility of a condition known as "apical periodontitis," where inflammation persists at the root tip, even after treatment. This can sometimes be identified through imaging studies, but in some cases, it may not be immediately visible on X-rays. If your dentist did not find any abnormalities on the X-ray, it might still be worthwhile to seek a second opinion from an endodontist, a specialist in root canal treatments. They may have more advanced diagnostic tools and techniques to evaluate the tooth and determine if there are any issues that were previously overlooked.

Regarding your question about whether to return to the original dentist or seek a new one, it ultimately depends on your comfort level and trust in the care you have received. If you feel that your concerns have not been adequately addressed, it may be beneficial to consult with another dentist or an endodontist for a fresh perspective. They can provide you with a thorough examination and discuss potential treatment options moving forward.

As for the timeline of waiting another two months before seeking treatment, it is generally advisable not to delay further if you are experiencing ongoing pain. Prolonging treatment could lead to more significant issues, including the potential loss of the tooth. Early intervention can often lead to better outcomes and may prevent the need for more invasive procedures, such as extraction.

In summary, persistent discomfort after root canal treatment should not be ignored. It is crucial to have a thorough evaluation to identify any underlying issues that may be contributing to your symptoms. Whether you choose to return to your original dentist or seek a second opinion, addressing the discomfort sooner rather than later is essential for the health of your tooth and overall oral health.
