I had visited my general dentist a few weeks prior for a root canal on an infected tooth. I sat in the chair for almost 3 hours and had more shots of novacaine then the average person. He could not get me numb, and I felt a lot of pain--he coudln't even work on me that day and sent me home. A few days later I visited Dr. Stieglitz and in 30 seconds I was fully numb. He performed the root canal and it was the best one I ever had. I didn't feel a thing and there was no discomfort after. I was even able to go to the gym that night. He's a great dentist, and I highly recommend him to anyone that's afraid of root canals!
