I wish Dr. Krupp could do my routine exams! Delivery of numbing agent was virtually painless (just very mild discomfort). Dr. Krupp explained each step, he and his office staff were very attentive. There was no point where I was left for an extended period of time. Even when I was waiting for the numbness to kick in, a member of his staff popped in every few minutes. Dr. Krupp performed the first root canal I have ever had and I have had a few filings that were more uncomfortable! A lot of the difference is the IV-like system that delivers the numbing agent as opposed to a big clunky cold needle that leaves a painful sore spot.
I highly recommend this office. It is nicely decorated as well. The room where the root canal took place was a nice pale green, while I was not being actively worked on, the lights were off, and the window looks out on nice green plants. It was very pleasant.
