I would guess that you bit your lip and didn't notice because of the anesthetic. I had a similar experience when I had my last oral surgery and I'm pretty sure the would was self-inflicted. While it certainly is possible that they screwed up and cut you, I wouldn't necessarily jump to that conclusion...

The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error. ~John Stuart Mill, On Liberty
