Gum Pain After New Dental Crown: Causes and Solutions - Dentistry

New braces causing gum pain?


Location: Right lower second molar (new crown made five months ago, experienced pain for three months making it difficult to eat, but X-rays showed no abnormalities).
Current condition (ongoing for one month): (1) No pain while eating, completely unaffected; applying pressure on the occlusal surface also causes no pain.
(2) The buccal gingiva is slightly swollen, and pressing on it causes pain, which increases with the amount of pressure applied.
(3) Brushing the buccal gingiva also causes slight discomfort, requiring gentle brushing.
My question is: After the completion of the new crown, there is a larger gap on one side between the adjacent tooth, which traps food every time I eat, while the other adjacent surface fits tightly and does not trap food, making it nearly impossible to floss.
Is this indicative of poor crown fabrication, or could excessive force during installation have caused misalignment? Thank you.

Hello, based on the situation described, since there is no impact on eating and no pain, it is recommended to return to your original dentist for an examination.
The process of making a dental crown is inherently complex, so please maintain good oral hygiene before your follow-up appointment.
Wishing you safety and health.
Sincerely, Dr.

More Info


Understanding gum pain after receiving a new dental crown can be quite complex, as it may stem from various underlying issues. Based on your description, it seems that the pain is localized to the outer gum area surrounding the second lower molar, which has been crowned for five months. The fact that you experience pain when pressing on the outer gum and when brushing suggests that there may be inflammation or irritation in that area.


Possible Causes of Gum Pain After Crown Placement
1. Gum Inflammation: The most common cause of gum pain after crown placement is inflammation of the gum tissue, often due to plaque accumulation or improper cleaning. If food particles are getting trapped between the crown and adjacent teeth, this can lead to irritation and inflammation of the gums.

2. Crown Fit Issues: If the crown does not fit properly, it can create spaces that allow food to become trapped, leading to gum irritation. You mentioned that one side has a larger gap while the other fits tightly. This discrepancy could indicate that the crown was not fabricated or seated correctly, which can lead to discomfort and pain.

3. Underlying Periodontal Issues: If there were pre-existing gum disease or periodontal issues before the crown was placed, these conditions could exacerbate after the procedure. The presence of inflammation in the gums can lead to pain, especially when pressure is applied.

4. Pressure from the Crown: If the crown is too high or improperly aligned, it can exert undue pressure on the surrounding gum tissue when biting or chewing, leading to discomfort.

5. Nerve Sensitivity: Sometimes, the nerves in the tooth or surrounding area can become sensitive after dental work, leading to pain that may not be directly related to the crown itself.


Solutions and Recommendations
1. Dental Evaluation: It is crucial to return to your dentist for a thorough evaluation. They may need to take new X-rays or conduct a clinical examination to assess the fit of the crown and the health of the surrounding gum tissue.

2. Cleaning and Maintenance: Ensure that you maintain excellent oral hygiene, especially around the crowned tooth. Using an antibacterial mouthwash and gentle brushing techniques can help reduce inflammation. If food is frequently getting stuck, consider using a water flosser to help clean the area more effectively.

3. Crown Adjustment: If the crown is found to be improperly fitted, your dentist may need to adjust it. This could involve reshaping the crown or even remaking it to ensure a better fit and reduce the gap that allows food to become trapped.

4. Periodontal Treatment: If gum disease is present, your dentist may recommend a professional cleaning or scaling to remove plaque and tartar buildup. This can help alleviate inflammation and pain.

5. Pain Management: Over-the-counter anti-inflammatory medications can help manage pain and reduce inflammation. However, this should be discussed with your dentist to ensure it is appropriate for your situation.

6. Follow-Up Care: Regular follow-up visits with your dentist are essential to monitor the situation. If the pain persists despite these interventions, further investigation may be necessary to rule out other issues, such as nerve problems or deeper periodontal concerns.

In summary, while your gum pain after receiving a new dental crown could be attributed to several factors, the most prudent course of action is to consult with your dentist for a comprehensive evaluation. They can provide tailored solutions based on the specific circumstances of your case, ensuring that your dental health is restored and maintained.
