Well, it is good to know there are others fearful of dentists out there! I have struggled with this for years... I panic even for a cleaning! Anyways, something I always find that works for me is telling the dental hygenist right off the bat that I'm a little nervous. From then on, they are usually pretty accomodating- offering water, asking if you're ok, etc. Good luck with the procedure and let us know how it goes!
