Biting down on a filled tooth can cause pain?

If a filled tooth hurts when biting down on hard objects, and the dentist previously mentioned that there was a deep cavity exposing the nerve but did not see any bleeding during the procedure, it is possible that the nerve may be irritated or inflamed.
The fact that there is no sensitivity to cold liquids suggests that the nerve may not be completely necrotic yet.
However, persistent pain when biting could indicate that the tooth is at risk for further complications.
It is advisable to consult with your dentist to evaluate whether a root canal treatment (nerve extraction) is necessary to prevent further damage or infection.

More Info

When experiencing pain while biting after a dental filling, it is crucial to understand the underlying causes and whether a root canal treatment is necessary. Based on your description, it seems that the dental filling was placed over a cavity that may have been close to the pulp, which is the innermost part of the tooth containing nerves and blood vessels. If the cavity was deep enough to expose or nearly expose the pulp, it can lead to inflammation or infection, resulting in pain when biting.

1. Understanding the Pain: The pain you feel when biting down could indicate that the pulp is irritated or inflamed. This condition is often referred to as pulpitis. If the pulp is still healthy, the pain may be temporary and could resolve on its own. However, if the pulp has become infected, a root canal may be necessary to remove the infected tissue and alleviate the pain.

2. Signs Indicating Root Canal Treatment: Certain signs suggest that a root canal might be necessary:
- Persistent pain when biting or chewing.

- Sensitivity to hot or cold that lingers after the stimulus is removed.

- Swelling or tenderness in the gums near the affected tooth.

- Discoloration of the tooth.

If you are only experiencing pain when biting but no other symptoms, it may not be an immediate indication for a root canal. However, it is essential to monitor the situation closely. If the pain worsens or other symptoms develop, seeking further evaluation from your dentist is crucial.

3. Consultation with Your Dentist: It is advisable to return to your dentist for a follow-up examination. They may perform additional diagnostic tests, such as X-rays, to assess the condition of the tooth and the surrounding bone. This will help determine if there is any infection or if the pulp is damaged.

4. Possible Treatment Options: If your dentist finds that the pulp is healthy, they may suggest monitoring the tooth for a short period. If the pulp is inflamed but not infected, they might recommend a procedure to relieve the pressure, such as a pulpotomy, where the inflamed tissue is removed, and the tooth is sealed. If the pulp is infected, a root canal treatment would be necessary to remove the infected tissue and prevent further complications.

5. Preventive Measures: To prevent similar issues in the future, maintaining good oral hygiene is essential. This includes regular brushing and flossing, routine dental check-ups, and avoiding hard foods that could damage fillings or teeth.

In conclusion, while the pain you're experiencing when biting down could indicate a need for a root canal, it is not definitive without further examination. It is essential to consult your dentist to evaluate the situation properly and determine the best course of action. Early intervention can prevent more severe complications and ensure the long-term health of your tooth.
