I order to reduce the pain after wisdom tooth extraction surgery it is generally advised to bite on the gauze pad periodically. The pad should be removed as soon as it gets soaked in blood.
You can also try applying warm moist compresses on the cheek, apply ice packs, and gently rinse your mouth with warm salt water. This will help in reducing the swelling and pain.
The possibility of dry socket also needs to be looked into by your dentist.
You might have dry socket. I would call your dentist ASAP. If you do have dry socket they can put gauze over the hole and the pain will drastically be reduced.
This happened to me when I had a tooth pulled a year ago.
