I'm cheap. Had a decayed molar, need a root canal treatment. I go to UMMC and got a doctor do a pulpectomy and the rest by undergrads; full checkup, and months of treatment. Yes, the waiting period is long; like half a year or so but they're really good and FREE.

But if you're staying nearby and can take some time out, its worth it. But if you're working and have inflexible time, go private.
