Get cheap dental work at your local dental school.
NOT, please don't do this. I had a nightmare from Hell doing this and still have pain. They made me sick w/infection and filled a tooth that needed root canal. I went back to get my money refunded and was hassled. It wasn't even THAT much cheaper ($90 for a full Xray set and $55 for the filling). They credited my CC most of the money after I bytched and moaned, but they really messed up my teeth. Some things in life you just don't skimp on. This is one of them. I found a good dentist willing to do the root canal for cheaper b/c I am not working now. He is gonna charge me around $650, and even tried to avoid doing it first by redoing what the students did. The dental school fscked my tooth and gums. The student was a ham-handed rookie. Their equipment was bad too. Don't go to a dental school please !!!
