It is possible to have some soreness after a wisdom tooth extraction, but pain starting for the first time around day 5 after having no pain at all is not something I would explain simply as “the nerves start sending pain signals because swelling decreases.” That explanation is not medically accurate.
Since the pain started immediately after the dentist examined the extraction site, local irritation or disturbance of the healing tissues is one possibility, especially if the area was manipulated. However, pain appearing around day 4–5 can also be seen with dry socket (alveolar osteitis) or, less commonly, infection, so the symptoms need to be monitored.
The fact that your dentist examined the site and confirmed that the clot was intact and healing appeared normal is reassuring.
Next Steps
* Follow the post-extraction instructions given by your dentist.
* Take the prescribed/appropriate pain medication if needed.
* Avoid touching the socket with your tongue, finger or toothbrush.
* Continue gentle oral hygiene around the area.
* Avoid smoking/vaping, alcohol and vigorous rinsing.
* If the pain is increasing rather than settling over the next 24–48 hours, contact your dentist for a review.
Health Tips
A dry socket typically causes significant, often worsening pain a few days after extraction, sometimes with pain radiating toward the ear/temple and an unpleasant taste or smell. An intact clot makes dry socket less likely, but symptoms and examination are more important than the timing alone.
If you develop increasing swelling, fever, pus, foul taste/odour, difficulty swallowing/breathing, or severe/worsening pain, seek dental attention promptly.
Overall, because the pain began right after the area was examined and your dentist saw a healthy clot, minor irritation from the examination is certainly possible, but I would not assume that day-5 pain is a normal consequence of “nerves waking up.”
