Dental implant issues?


Hello, Doctor: After completing root canal treatment and placing the post, I feel a slight sensitivity when gently pressing or tapping the surface of the dental crown with my finger.
Is this normal? What could be the possible reasons? Thank you!

Hello Natasha: If you have undergone root canal treatment and had a post and crown placed, and you still experience slight sensitivity when tapping on the crown surface, it is possible that there is inflammation at the gum margin of the crown.
It is recommended to return for a follow-up appointment with your dentist for further examination.

More Info


Post-endodontic discomfort is a common experience for many patients following root canal treatment. It is important to understand that some level of discomfort or sensitivity can be expected after such procedures, and this can vary from person to person.

Is It Normal?
Yes, experiencing mild discomfort or sensitivity after root canal treatment is generally considered normal. This can occur due to several reasons:
1. Inflammation: The procedure itself can cause inflammation in the surrounding tissues. The manipulation of the tooth and the cleaning of the root canals can lead to temporary irritation of the periapical tissues (the tissues surrounding the root of the tooth).

2. Pressure Sensitivity: After the placement of a post and crown, the tooth may feel different, and pressure sensitivity can arise. This is particularly true if the tooth was previously infected or if there was significant damage before the treatment.

3. Healing Process: The body’s natural healing response can lead to discomfort as the tissues around the tooth recover. This healing process can take several days to weeks, depending on the individual’s health and the complexity of the treatment.

4. Occlusal Issues: If the bite is not properly adjusted after the crown is placed, it can lead to discomfort when biting or applying pressure to the tooth. This is often referred to as "high spots" on the crown, which can be easily adjusted by your dentist.


Possible Causes of Discomfort
1. Post-operative Pain: This is the most common cause of discomfort. It can be managed with over-the-counter pain relievers such as ibuprofen or acetaminophen.

2. Infection: In some cases, if the discomfort persists or worsens, it may indicate an underlying infection that was not fully resolved during the root canal treatment. This could require further evaluation and possibly retreatment.

3. Nerve Irritation: The procedure may have caused temporary irritation to the nerves in the area, leading to discomfort that should subside as healing progresses.

4. Allergic Reaction: Although rare, some patients may have an allergic reaction to the materials used in the post or crown, which could lead to discomfort.


When to Seek Help
While mild discomfort is normal, you should contact your dentist if you experience:
- Severe pain that does not improve with over-the-counter medications.

- Swelling or redness around the treated area.

- Discomfort that persists beyond a few days or worsens over time.

- Any signs of infection, such as fever or discharge.


Conclusion
In summary, mild discomfort following root canal treatment and the placement of a post and crown is typically normal and can be attributed to inflammation, healing processes, or occlusal issues. However, it is essential to monitor your symptoms and communicate with your dentist if you have concerns or if the discomfort escalates. Your dental professional can provide guidance and adjustments to ensure your recovery is smooth and comfortable. Always remember that your comfort and health are paramount, and your dentist is there to assist you through the healing process.
