OK, I can try to help because my brother in law is a dentist. First, did you go see the specialist yet? You should DEFINITELY tell her all your concerns, esp about the dam. They have seen it all, believe me. And I will bet she will give you some ativan or xanax or similar to take before your appt, sometimes even the night before and then right before (someone will need to drive you home though). There are many ways to work around it and you will feel much better and so will she when she is aware of your fears. There are tons of people who fear or just hate the dentist, and they want it to be as easy and comfortable for you as possible (it makes their job easier too!!). Good luck and keep us posted.
