Consider going to a dental school to get the work done.
The only problem is there are only 60 dental colleges in the U.S. so finding one near you could be a problem.
Most of the schools accept dental insurance, and the bill will generally be about half the cost you'd pay in a dentist's office.
Professors oversee the students every step of the way. Student dentists preform everything from fillings to root canals.
I have a friend who goes to a dental school for his work and he's very pleased.
So if you live near one, lucky you.
