oh boy tso, all these decisions over a small cavity. Let me put some perspective on this. I know you're only 22, and at the beginning of adulthood, but take it from an old lady like myself, as your life continues dentistry will be at the very low end of things that scare you. I know these procedures are all new to you and you will in time accept them as no big deal. The big deals like marriage, children, health, financial concerns are the ones that in some cases can drive people over the edge. I advise you to just accept that you're going to go through with it no matter how you feel, you have a long way to go and you certainly want to have a healthy mouth all your life. Now please understand I don't want you to think I'm making light of your fears, at your age I was afraid to drive and you probably think that's crazy. I didn't get my license until age 26. Just want you to look at the big picture and try to put things in perspective. There's a whole lot more than can hurt you out there than a dentist's drill. Good luck at your appt., I believe it will turn out good and you will be relieved.
