So I went ahead and called the *expletive deleted*. I have an appointment Saturday morning at 9:30. It really didn't help when cthulhia came into my cubicle and said "If you can see the cavity, you probably need a root canal." Nevertheless, I made an appointment. And, hey, at least I don't have to take time off of work for it. I'm a bit nervous. I mean, I'm sure it will be fine, and I'm sure I'll feel a lot better knowing my teeth aren't going to fall out. Still.
