I would suggest finding a dentist that doesn't freak you out. I have severe dental anxiety (and every other kind of anxiety). It caused me to neglect my teeth for MANY years. It took nearly a dozen dentists before I found one I'm comfortable with.
I cry and have full blown panic attacks. I've been yelled at by several dentists and kicked out of a few offices. My current one is very patient with me, and is good with the needle. He talks to me like I'm a four year old, but considering how much I've cried around him I can't really blame him.
