I had all four of mine taken out at once too. It was HELL. I was swollen like a chipmunk and I bruised for almost a month. I couldn't eat or drink for the longest time. I thought I was going to die of malnutrition or something.
Hmm.. My brother got his wisdom teeth pulled out and the novacaine stuff kept his mouth numb.. so he couldn't really feel it, I think.. -_-" But he told me something about the dentist using a drill or something O.O Anyways, you could feel BONE?! Eep...
Gah, I hate the dentist. Stupid dentist always has to fix my cavities and my mom starts yelling if I get like 4 more cavities, lol. -_-"
