Wisdom tooth restoration?


Doctor, a few days ago I went to the dentist, and the dentist said that my wisdom tooth had a cavity.
After treating it, they filled it again, but after a day or two, I experienced significant pain when I bit down on the filled area.
I returned for a follow-up, but both dentists at that clinic said there was no cavity anymore and that I had gum inflammation.
Why does it only hurt when pressure is applied to the wisdom tooth?

Dear user, based on your description, it seems that your wisdom tooth has undergone filling and treatment for cavities.
After the filling, you are experiencing occlusal pain.
It is advisable to consult your dentist to check if an adjustment to your occlusion is necessary and to assess whether there is any inflammation in the periodontal tissues or gums.
Monitor the treated tooth to see if the symptoms improve or if the pain becomes more pronounced.
If the occlusal pain worsens or if there are other symptoms, please seek further evaluation and treatment from your dentist.
Additionally, if necessary, consider assessing the condition of the wisdom tooth to determine if extraction is required.
Thank you for your inquiry.

Understanding wisdom tooth pain after dental filling can be quite complex, especially when the pain persists after treatment. In your case, it seems that the pain is localized to the area where the filling was placed, which can indicate several underlying issues.

Firstly, it’s important to understand that after a dental filling, especially in a wisdom tooth, some discomfort is normal. This is due to the trauma that the tooth and surrounding tissues experience during the procedure. However, if the pain is significant and persists beyond a few days, it may suggest other complications.

One common cause of pain after a filling is pulpitis, which is inflammation of the dental pulp inside the tooth. This can occur if the decay was deep and close to the nerve, or if the filling material has irritated the pulp. Symptoms of pulpitis can include sharp pain when biting down or sensitivity to hot and cold temperatures. If the pulp becomes severely inflamed, it may require further treatment, such as a root canal.

Another possibility is that the filling itself is too high, meaning that it is not properly adjusted to fit the bite. When you bite down, the filled tooth may come into contact with the opposing tooth too early, leading to discomfort. This is often referred to as "bite trauma." If this is the case, your dentist can easily adjust the filling to alleviate the pressure.

Additionally, you mentioned that the dentists noted gingival inflammation (gum inflammation). This could also be a contributing factor to your pain. If the gums around the wisdom tooth are inflamed, they may be sensitive to pressure, especially when chewing. This inflammation can be due to food particles getting trapped around the tooth, poor oral hygiene, or even the positioning of the wisdom tooth itself, which can make it difficult to clean properly.

In some cases, the wisdom tooth may be partially erupted, which can create a pocket where bacteria can thrive, leading to pericoronitis (inflammation of the gum tissue around a partially erupted tooth). This condition can cause pain and swelling, particularly when pressure is applied.

To address your pain, here are some steps you can take:
1. Follow-Up with Your Dentist: Since the pain persists, it’s crucial to return to your dentist for a follow-up. They can assess the filling, check for any signs of pulpitis or infection, and make necessary adjustments.

2. Pain Management: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage the pain. However, consult your dentist before taking any medication, especially if you have other health conditions.

3. Maintain Oral Hygiene: Ensure that you are maintaining good oral hygiene, especially around the wisdom tooth. Use a soft-bristled toothbrush and consider using an antibacterial mouthwash to help reduce inflammation.

4. Avoid Hard Foods: Until the pain subsides, try to avoid hard or crunchy foods that may put additional pressure on the affected tooth.

5. Ice Packs: Applying a cold pack to the outside of your cheek can help reduce swelling and numb the pain.

6. Monitor Symptoms: Keep track of any changes in your symptoms. If you experience increased swelling, fever, or pus, seek immediate dental care as these may indicate an infection.

In summary, while some discomfort after a dental filling is normal, persistent pain warrants further investigation. It could be due to pulpitis, bite trauma, or gum inflammation. A thorough examination by your dentist will help determine the exact cause and appropriate treatment to alleviate your pain.
