###Human: Why is there a swelling at the site of wisdom tooth removal? ###Assistant: Hello. I have been through your query and I can understand your concern. Post-extraction swelling is normal as the tissues require a conducive environment for healing. Normally, an extraction site shows almost complete healing after 21 days provided you do not have any negative habits like smoking and have followed the instructions perfectly. In your case, it seems there was surgical removal of the tooth which requires an incision, bone cutting and sutures. If that was the case, it would take roughly around 4 or 5 weeks for the wound to heal completely. The swelling will also subside with the coming days. I would suggest you to wait and follow the instructions of your dentist. However, if the swelling continues to remain there for even longer time, and if you feel discomfort then I would suggest you to go to your dentist at that time. I would also suggest you doing normal saline oral rinses with warm water but very gently (in order to not destabilize the clot of the wound). Maintain good oral hygiene. Follow up after 15 days for the results.
