I needed a root canal and Dr. Jespersen was clinically efficient. The procedure was about 80% painless - some deep anesthetic injections were required which hurt a little in the beginning given the pain sensitivity of the tooth. However, he completed the entire procedure in less than an hour. They were also able to fit me in on an emergency basis. The only thing that bothered me is that he is very busy and will usually leave his dental assistant to answer routine questions. Now I need to go back to my regular dentist and get a permanent fillling and crown on the tooth.
