Hatchling bites don't hurt at all, and if you get a rapid-fire repeat biter it's like being attacked by velcro. Adult bites sting a bit, like needle pricks, but much less than being bit by a puppy or a kitten. Some people do have a reaction to the saliva and the bites itch afterwards (I do!) I had a tooth from an adult left in a bite a while back, it worked back out after a couple of days, like a small splinter would. No harm to me, I was more worried about the snake possibly getting mouthrot, but he was ok too.
