I must've been going to some ghetto dentist for all these years then. Whenever I happened to get a cavity they would just lay me down and start working without the numbing. It really doesn't hurt at all, I felt a sort of stabby feeling at the tooth but I got used to it.
Were they full cavities or just gap fillings? I've had one cavity before and the dentist gave me a shot but with the gap fillings there was no numbing used; just grind the surface of the teeth a bit and fill it in with resin.
What's with y'all getting so many cavities? You probably have some skank ass breath to go along with them. Remember to brush and floss daily kids.
