Tooth Sensitivity After Crown Placement: Causes and Solutions - Dentistry

More Info

---

Tooth sensitivity after crown placement can be a common issue, especially when there are underlying conditions such as previous root canal treatments or gum recession. In your case, the sensitivity you are experiencing in your upper right premolar, particularly after the placement of a temporary crown, can be attributed to several factors.


Causes of Tooth Sensitivity After Crown Placement
1. Temporary Crown Sensitivity: Temporary crowns are often made from materials that may not provide the same level of insulation as permanent crowns. This can lead to increased sensitivity to temperature changes, pressure, and even air exposure. The sensitivity you feel, especially in the morning, could be due to the crown not fully sealing the tooth, allowing stimuli to reach the nerve endings.

2. Gum Recession: As you mentioned, your dentist noted that the gum tissue around the tooth has not grown sufficiently, leading to larger gaps between the teeth. When the gums recede, the tooth roots become exposed, which can lead to sensitivity. The roots are not covered by enamel, making them more susceptible to temperature changes and tactile stimuli.

3. Underlying Dental Issues: If the tooth has undergone root canal treatment, it is less likely to be sensitive in the same way as a healthy tooth. However, if there is any residual infection or inflammation in the surrounding tissues, this could lead to discomfort and sensitivity.

4. Bruxism (Teeth Grinding): Your habit of grinding your teeth can contribute to wear and tear on the crown and the underlying tooth structure, leading to increased sensitivity. This can also cause the crown to become loose or misaligned, exacerbating the problem.


Solutions to Improve Tooth Sensitivity
1. Consult Your Dentist: The first step is to return to your dentist for a thorough examination. They can assess the fit of the temporary crown, check for any signs of infection, and evaluate the condition of your gums. If the crown is not fitting properly, it may need to be adjusted or replaced.

2. Desensitizing Toothpaste: Using a toothpaste specifically designed for sensitive teeth, such as Sensodyne, can help reduce sensitivity over time. These toothpastes contain compounds that block the transmission of pain signals from the tooth surface to the nerve.

3. Gum Grafting: If gum recession is significant, you might consider discussing gum grafting with a periodontist. This procedure can help restore gum tissue around the tooth, reducing sensitivity and improving aesthetics.

4. Night Guards: If bruxism is a contributing factor, wearing a night guard can help protect your teeth from grinding during sleep. This can alleviate pressure on the tooth and reduce sensitivity.

5. Avoid Certain Foods: While you are experiencing sensitivity, it may be beneficial to avoid extremely hot, cold, or sweet foods that can trigger discomfort.
6. Maintain Oral Hygiene: Continue to practice good oral hygiene, including brushing with a soft-bristled toothbrush and flossing gently around the affected area to prevent further irritation.


Conclusion
Tooth sensitivity after crown placement can stem from various factors, including the nature of the temporary crown, gum recession, and habits like teeth grinding. It is essential to consult with your dentist to determine the exact cause and appropriate treatment. By addressing these issues, you can significantly improve your comfort and maintain your dental health.
