When I went to Dentalville there was no pain or discomfort. There isn't even the threat of it, because the dentist was very calm, friendly, and genuinely concerned about making me feel comfortable. He thoroughly explains all procedures, and not only tells you what you might want to consider improving about your tooth care, but he also he tells you WHY. I love knowing the why, as it's a better motivator. And if you ask questions, it's basically like a crash course in dentistry.
Overall, this is easily the best dentist's office I've ever been to. They are up to date on all the latest dental technology, the dentists answer all my dumb questions, there was minimal scolding for not flossing as much as I should and waiting so long between visits.
Pros: calm,friendly and concerned
