It is common to feel some discomfort after you have had a tooth taken out, especially if it was more complex. Use painkillers as advised by your dentist to manage the pain. If you experience intense pain a few days after an extraction, you may have a condition known as dry socket, which occurs when a blood clot fails to form or is dislodged prematurely, exposing the bone. In this case, you will need to see the dentist who will help to rectify the problem and alleviate any pain.
