About how much cheaper is it to get dental work done at a dental school?

I've been looking for a job for a long time, but I can't find one. I really want to take care of my dental issues (I know I need one root canal and two small fillings), but my parents can't afford how high it is (esp. for a root canal). But I hate to wait because the things that are small issues only grow into bigger issues... I'm thinking about going to the local dental school, but I'm wondering if I can afford even that right now.

You will save at least 50% and probably more. Let them do an exam on you and they will let you know what the work will cost.
