After root canal treatment, lightly tapping on the occlusal surface of the crown feels slightly sensitive?
Hello, Doctor: I have undergone root canal treatment on my upper left second molar and lower left second molar (a total of two teeth), and after placing dental posts for stabilization, I am currently on the 10th day of trying on the dentures.
I do not experience any pain or discomfort while chewing food, but (1) after the dental posts were placed, I feel a slight soreness when I gently press on the occlusal surface of the posts with my finger.
(2) Currently, when I lightly press or tap the occlusal surface of the dentures with my finger, I feel a mild soreness.
(3) On the night of the 6th day of trying on the dentures, I experienced some pain near the contact point of the upper second molar for over an hour.
I used dental floss to clean the interproximal space but did not find any food debris.
(I had previously experienced pain during the root canal treatment due to temporary dentures trapping food debris.) My questions are: (1) Is it possible that the root canal treatment was not thorough? If so, would reopening the fixed dental posts and performing the root canal treatment again resolve the issue? (2) If the fixed dental posts need to be reopened, is there a high risk of the posts breaking and remaining in the gums? (3) Can the doctor determine through X-rays whether the root canal treatment was performed adequately? I appreciate your response.

More Info
Post-root canal treatment discomfort is a common concern for many patients, especially when they have undergone additional procedures such as the placement of dental posts and crowns. Your situation, involving mild discomfort after root canal therapy and the subsequent placement of a denture, raises several important questions that can be addressed based on dental principles and practices.
1. Possibility of Incomplete Root Canal Treatment: It is indeed possible that the root canal treatment was not entirely effective, which could lead to lingering discomfort. Factors such as complex root canal anatomy, missed canals, or inadequate cleaning and sealing can contribute to this issue. If there is suspicion that the root canal treatment was not thorough, it may be necessary to reopen the tooth and perform retreatment. This process involves removing the post, cleaning the canals again, and ensuring that they are properly sealed. However, this decision should be made in consultation with your dentist, who can evaluate the situation based on clinical findings and possibly imaging.
2. Risks Associated with Removing Dental Posts: When it comes to removing a dental post, there is a risk of the post fracturing during the removal process, which could lead to complications such as fragments remaining in the root canal or gum tissue. This is particularly a concern if the post is cemented in place. Dentists often use specialized techniques and tools to minimize this risk, but it is essential to discuss these concerns with your dentist. They may have a plan in place to safely remove the post and address any complications that arise.
3. Role of X-rays in Assessing Root Canal Treatment: X-rays are a valuable tool in evaluating the success of root canal treatment. They can help visualize the root canal system, check for any signs of infection, and assess the quality of the filling material used in the canals. However, while X-rays can provide significant information, they may not always reveal all issues, especially if there are microscopic problems or if the canals are not visible on the X-ray. Therefore, clinical examination and patient symptoms are also critical in determining the success of the treatment.
In addition to these points, it’s important to consider the nature of the discomfort you are experiencing. Mild discomfort or sensitivity when pressing on the tooth or denture can be a normal part of the healing process, especially after extensive dental work. However, if the discomfort persists or worsens, it is crucial to follow up with your dentist. They may recommend pain management strategies, such as over-the-counter pain relievers, and provide guidance on how to care for your denture during the healing phase.
Moreover, if you experience any swelling, increased pain, or signs of infection (such as fever or pus), it is essential to seek immediate dental care. These symptoms could indicate a more serious issue that requires prompt attention.
In summary, while mild discomfort after root canal treatment and the placement of a denture can be common, it is essential to monitor your symptoms closely. Open communication with your dentist will help ensure that any potential issues are addressed promptly and effectively, allowing for a smoother recovery and better long-term outcomes for your dental health.
