Naaah, don't worry, jabe, dentists are fine. The majority of them totally understand a patient's case of the jitters. I do understand how you feel, tho'. I hope this helps: Each time I see my dentist or periodontist, I remember that they are nowadays very well-trained in bedside manner. Why, just this Monday I saw my dentist, had x-rays and he told me what I needed to do (which was not so hard to stomach, fortunately).
Anyways, I'm sure you'll feel soooo much better once it's over and done with. And, if you need a follow-up visit. It'll be a piece of cake compared to this initial visit.
