callisto, (with all due respect to larry) many dentists are small practitioners who make a lot of money from their labor costs. often, they are willing to work out a deal, such as bartering things like landscaping or housecleaning to pay for the work they perform on your choppers.
another suggestion is to find a dental school. you get what you pay for, but at least you'll get things fixed.
