See if there's a dental school near you. I'm in Michigan and in the same situation. Univ. of Michigan Dentistry School has a very large clinic that not only helps the students get their skills ready for graduation, they offer very affordable rates. Example - I needed a tooth pulled -- quotes from several dentists averaged almost $300. It cost me $70 at the dental school.
I'm very impressed with how thorough they are and there are professors who work very closely with the students. They don't go onto the clinic floor until they're almost ready to graduate.
Rambling but very impressed and getting much-needed work done.
