Depends on how bad the pain is, and where it is.
If it's not bad enough to impede daily activities, I usually just take a couple aspirin.
But if it's a lingering pain (such as one of those stubborn headaches) or it's really bad, I take 800mg of ibuprofen.
The only time I've ever used something super strong was the two percocet that they gave me in the hospital when I went in with a nasty infection from a horizontally impacted wisdom tooth.
The pain was so bad that even eating pudding made me tear up, and I had this unsightly golf ball sized lump on my lower cheek...not fun given how wide they make you open up to check your mouth. x_x
