Post-operative issues after wisdom tooth extraction?


On August 16, I had my lower left wisdom tooth extracted, and on August 18, I started experiencing pain in my first molar, similar to a cavity (there were no such issues before the wisdom tooth extraction).
Could the pain in my first molar be caused by the wisdom tooth, or is it simply a cavity?

Hello: It may still be an issue related to the wisdom tooth surgery.
It is recommended to return for a follow-up appointment to have the doctor check for any cavities in the molars when the stitches are removed.

More Info


After wisdom tooth extraction, it is not uncommon for patients to experience discomfort or pain in adjacent teeth, including the molars. In your case, since you had your lower left wisdom tooth extracted on August 16 and began experiencing pain in your first molar on August 18, there are several potential explanations for this discomfort.

1. Post-Operative Pain: After the extraction of a wisdom tooth, it is possible for the surrounding teeth to experience some degree of discomfort. This can be due to inflammation or trauma to the area during the extraction process. The extraction site can also lead to referred pain, where pain is felt in a different location than its source.

2. Cavity Development: If the first molar was already susceptible to cavities, the extraction process could have exacerbated the situation. The stress and changes in the oral environment following the extraction might have accelerated the development of a cavity, especially if there were pre-existing conditions that made the tooth vulnerable.

3. Impaction or Positioning: Sometimes, the removal of a wisdom tooth can lead to changes in the alignment of adjacent teeth. If the first molar was previously in a stable position, the extraction could have altered its position, leading to discomfort or pain that mimics the sensation of a cavity.

4. Infection: Another possibility is that an infection could have developed in the extraction site, which can cause pain that radiates to nearby teeth. If the extraction site becomes infected, it can lead to complications that affect adjacent teeth.

5. Dry Socket: A condition known as dry socket can occur after tooth extraction, where the blood clot at the extraction site becomes dislodged or dissolves, exposing the bone and nerves underneath. This can lead to significant pain that may radiate to nearby teeth.

Given these possibilities, it is essential to consult with your dentist or oral surgeon. They can perform a thorough examination, possibly including X-rays, to determine the exact cause of your molar pain. They will be able to assess whether the pain is due to a cavity, a complication from the extraction, or another dental issue.

In the meantime, here are some recommendations to manage your discomfort:
- Pain Relief: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help alleviate pain. Be sure to follow the recommended dosages.

- Oral Hygiene: Maintain good oral hygiene by gently brushing your teeth and rinsing with warm salt water to help keep the extraction site clean and reduce the risk of infection.

- Avoid Irritants: Try to avoid hard, crunchy, or sticky foods that could irritate the extraction site or the painful molar.

In summary, while it is possible that the pain in your first molar is related to cavities, it could also be due to other factors related to the wisdom tooth extraction. A professional evaluation is crucial to determine the underlying cause and to receive appropriate treatment.
