Cavities

The results from my dental exrays say that I have 2 cavities . I have to go back in 2 weeks to get them filled. That means that I get to have shots. Shots in my mouth. Strangely enough, those needles never seem to bother me. I go back to the dentist on April 12. I am not bothered by that. The appt that really does bother me a little bit is the one in front of the traffic court that I have on April 4. I am getting a diversion. Has anyon e had one of these? What am I supposed to bring?
