Hi,
Thank you for the query.
Wisdom tooth surgeries do take a bit of time to heal. Depending on the amount of infection present at the time of surgery, this could delay healing. However, different people have different healing capacity, so the range of 7-10 days is a range but doesnt necessarily be the same for everyone.
With regards to the swelling, if there was considerable amount of bone removed during the surgery, the swelling will take a little more time to resolve.
All in all, there is nothing to worry. Just need to be giving yourself time to heal.
Next Steps
Visit the dentist for a check up and follow up. Follow the medications precisely.
