Why Your Tooth Hurts After Filling: When to Seek Dental Help - Dentistry

More Info

After a dental filling, it is not uncommon to experience some discomfort or sensitivity in the treated tooth. However, if the pain persists for more than a few weeks, as in your case, it may indicate an underlying issue that requires further evaluation by a dental professional.


Understanding Tooth Sensitivity After Filling
Tooth sensitivity after a filling can occur for several reasons:
1. Inflammation of the Pulp: The dental pulp, which contains nerves and blood vessels, can become inflamed after a filling. This inflammation can cause pain, especially when biting down or consuming hot or cold foods.

2. High Filling: If the filling is too high, it can cause discomfort when you bite down, leading to pain. This is often described as a feeling of pressure or discomfort when chewing.

3. Cracked Tooth: If the tooth was already compromised before the filling, it might be cracked or fractured, which can lead to pain when chewing.

4. Sensitivity to Temperature: After a filling, it is common for teeth to become sensitive to hot and cold temperatures. This sensitivity may improve over time but can persist if the pulp is irritated.

5. Underlying Dental Issues: If there was pre-existing decay or damage to the tooth, the filling may not have addressed all the issues, leading to ongoing pain.


When to Seek Dental Help
Given that you have been experiencing pain for over a month, it is advisable to seek dental help. Here are some signs that indicate you should see your dentist:
- Persistent Pain: If the pain does not subside or worsens over time.

- Pain When Biting: If you experience pain when biting down, this could indicate a high filling or a cracked tooth.

- Sensitivity to Temperature: If you have increased sensitivity to hot or cold that does not improve.

- Pain Radiating to Other Areas: If you notice pain radiating to your jaw, ear, or temple, this could indicate issues with your temporomandibular joint (TMJ).


Addressing TMJ Pain
You mentioned experiencing pain near your ear, which could be related to TMJ issues, especially if you have been favoring one side for chewing. TMJ disorders can arise from uneven bite forces, leading to muscle strain and discomfort. If you suspect TMJ involvement, it is essential to discuss this with your dentist, as they may recommend treatments such as:
- Bite Adjustment: If the filling is too high, your dentist can adjust it to ensure even contact when biting.

- Mouthguard: A custom mouthguard can help alleviate pressure on the jaw and reduce grinding or clenching.

- Physical Therapy: Exercises may help strengthen the jaw muscles and improve function.


Using Sensitivity Toothpaste
Using a sensitivity toothpaste can help alleviate discomfort associated with tooth sensitivity. These toothpastes contain compounds that block transmission of pain signals from the tooth surface to the nerve. However, if the underlying issue is not addressed, sensitivity toothpaste may only provide temporary relief.


Conclusion
In summary, it is crucial to follow up with your dentist regarding the persistent pain after your filling. They can assess the situation, determine if the filling needs adjustment, or if further treatment is necessary. Additionally, addressing any TMJ-related discomfort is essential for your overall oral health. Do not hesitate to seek help, as early intervention can prevent more significant issues down the line.
