I had an emergency crown done last year, at about the same time as my best friend. Dr. K is a Cerec dentist - I can't recommend this enough. He did the crown and root canal in about 2 1/2 hours. Done, completely. My friend had to go to her dentist three times, at about 2 hours per visit, and the crown still wasn't quite right. He is very good, friendly and helpful. His staff is excellent.
