Should I tell my dentist he ruined my life?!

Five years ago at Christmas, I was helping my disabled wife into the car. When she started to fall, I tried to catch her and knocked out both front teeth on the car door. My dentist offered an alternative to a partial plate (I'm sorry, I can't recall the name) and built two new teeth right there in his office, attaching them to the stumps. Each tooth took two hours and cost $800 a piece. They looked great but when I went home, the pain wasn't subsiding and I returned to him twice in the next two weeks. He was puzzled as to the reason and kept filing the teeth down to the extent that they don't meet the lower ones so I can't bite and sever anything (like a hangnail, etc.) In the time that's passed, the area of pain, which never subsides (It's like having a iron held against your face - sometimes on high and other times on low) has spread from my cheek to my eyes, nose and upper gums. I'm a veteran so go to the VA for my health care and after five years, I've finally realized that they don't know what to do with me, having no experience with my condition which I'm certain is Trigeminal Neuralgia. I did go to a clinic specializing in this hoping that nerve surgery would help. They said it would not help the type of nerve damage I have but they would be happy to talk with my VA doctor and instruct her on the the treatment of this terrible condition. My VA doc called me at work, nearly in hysterics, yelling that they could wash their hands after talking to her so she would not be calling them! I just thought it was nice of them to offer to help. In the mean time, I needed some routine dental work done, and went to a new dentist in the next town. When I told him about my condition, he confidently stated that he had just attended a dental conference where it was proclaimed that Trigeminal Neuralgia could not be caused by dental procedures! After my routine cleaning cleaning and a few fillings, my condition worsened for 8 months and is just now calming down, though I'm still in horrific pain every day. My father says I should write the original dentist a letter telling him what he did to me. What do you folks recommend?
