Fear of Dentist is sure distressing and frustrating especially when you need to go, but can't!
For me, the only way that I overcame my fear of the dentist was by systematic desensitization. I do not know if you have heard of the term or not, but it simply means that the more times you do something...the more likely your fear will be reduced.
Two summers ago, I had a tooth that needed a root canal but there was one root that no dentist could get to. I went all over pittsburgh looking for a dentist to work on my tooth. In the process of having dentists constantly in my mouth, I became more and more comfortable with the concept and with the visits!
To this day,I do not fear the dentist and it was such a relief because I had feared it since I was a small child.
Of course, I do not know if you are able to go to the dentist every week, but I just know that systematic densensitization worked for me!
I hope you find the help that you need! Take Care.
