Good day
Surgical pain, especially with difficult extractions, in which bone had to be removed, can sometimes last up until 2 weeks. Remember every person's healing process is also unique.
If you went for a check up with the dentist, and he indicated that everything seems well, then everything should return to normal. Just be patient. You can take some painkillers, especially anti-inflammatory meds.
If the pain is not getting better each day, and you still have severe pain after 2 weeks, go back to your dentist, so that further investigations can be done.
