What are some problems after wisdom tooth extraction?

Not many: As far as healing goes if you follow all of the pre and post operative instructions. My patients have little if any swelling or post operative pain and I do 99% of them under local only. Most have them removed on a thurs and are back in the world on monday. If your case is more complex with the nerve being involved other issue may arise however if it is straight forward the above applies.

Wisdom teeth: Most patients undergo extraction of wisdom teeth uneventfully and predictably. You should expect to experience some pain for a few days, about 3-4 days of swelling, perhaps some slight bruising and limited opening of the mouth. You'll be on a liquid diet for a few days followed by a soft diet for another few days. Most patients are back to normal in about a week, but many return to work sooner.

Many : Many but uncommon. Can have pain, swelling, limited jaw opening, bleeding, dry socket, infection, sinus issues, numb lower lip or tongue, mandible fracture.
