I had a root canal by Dr. Nelson. I was very apprehensive as this was my first one. The doctor and his staff were very nice and comforting and the procedure did not hurt at all. Dr. Nelson made sure that I was good and numb before he started. The location is on East Sahara and the office is no frills but clean. I would definitely go back to Dr. Nelson if I needed another. He is quite a talker too!
