I am terrified of the dentist as well. I don't know what part of the experience is your phobia, but it's very common to have fears/phobias around dentists and dental work. There's nothing to be ashamed of. You might be surprised at the number of people who share your phobia I eventually had to just go to the appointment and explain how scared I was. They prescribed me a very strong anti-anxiety medication and I got through the work that needed to be done. They did a lot of things to try to help me calm down, like talking reassuringly to me throughout, and they allowed me to "participate" to feel more in control of the situation. I can totally understand how scary it is, though.
