Which over-the-counter pain reliever works best after tooth extraction?

Ibuprofen: Ibuprofen 600-800mg taken every six hours works great. If allergic to aspirin, nsaids or are taking blood thinners ask your doctor first. Acetaminophen (paracetamol) 650mg every 6 hours will help, but will not control the inflammation that causes the pain. If needed, you can take both if you don't exceed 3200mg Ibuprofen or 3000mg Acetaminophen per day. Talk to your dentist for specific help.
