Experiencing severe pain after a dental filling, especially following a deep cavity treatment, can be concerning. It is not uncommon for patients to feel discomfort after dental procedures, but the intensity and duration of the pain can vary based on several factors.

Firstly, it’s essential to understand that after a dental filling, particularly when dealing with deep cavities, some level of discomfort is expected. This is due to the trauma inflicted on the tooth and surrounding tissues during the procedure. The pain you are experiencing could be attributed to several reasons:
1. Inflammation: The dental procedure can cause inflammation in the pulp (the innermost part of the tooth containing nerves and blood vessels), leading to pain. This inflammation can take a few days to subside.

2. Pulpitis: If the cavity was deep enough to affect the pulp, you might be experiencing pulpitis, which is an inflammation of the dental pulp. This condition can cause significant pain and may require further treatment, such as root canal therapy.

3. High Filling: If the filling is too high, it can cause discomfort when biting down. This can lead to pressure on the tooth and surrounding tissues, resulting in pain. If you feel that the filling is too high, it’s advisable to return to your dentist for an adjustment.

4. Infection: In some cases, if bacteria have penetrated the tooth during the cavity treatment, it can lead to an infection, which may cause severe pain and swelling. Signs of infection include persistent pain, swelling, and sometimes fever.

5. Sensitivity: After a filling, especially if it’s a composite or amalgam filling, you may experience heightened sensitivity to temperature changes or pressure. This sensitivity can last for a few days to weeks, depending on the individual’s healing process.

Regarding the duration of pain, it typically should start to improve within a few days post-treatment. If the pain persists beyond a week or worsens, it is crucial to contact your dentist. They may need to evaluate the filling, check for any underlying issues, and determine if further treatment is necessary.

In the meantime, here are some suggestions to help manage your pain:
- Over-the-Counter Pain Relievers: Continue taking over-the-counter pain medications as directed. Ibuprofen or acetaminophen can help alleviate discomfort.


- Cold Compress: Applying a cold compress to the outside of your cheek can help reduce swelling and numb the area, providing some relief.

- Avoid Hard Foods: Stick to soft foods and avoid chewing on the affected side until the pain subsides.

- Saltwater Rinse: Rinsing your mouth with warm salt water can help reduce inflammation and promote healing.

In summary, while some pain after a dental filling is normal, severe and persistent pain warrants further evaluation by your dentist. They can determine the cause of your discomfort and provide appropriate treatment to ensure your recovery. If you have any concerns about your symptoms or the healing process, do not hesitate to reach out to your dental care provider for guidance.
