Ouch =( Dang I'm sorry... But in all honesty lol something like that just happened to me, only I was going down my bike and decided to try to fly. (fly = hitting a pothole and landing mouth first) But what they can do, is just if there's no swelling, they can go ahead and fix it entirely. If there is, what they'l do is just clean it up and put a cap on the tooth, and then replace the crown when your lips heal.
