Dr. Brough is an excellent endodontist and my root canal treatment was completely successful. His office and staff were fine, and he is a very nice person - warm, kind and gentle - and made me feel very comfortable despite my condition (I had a severe infection and I was taking painkillers and antibiotics). Alas, the procdure itsef was extremely uncomfortable and once it was over and I tried getting up from the chair, just as the Demerol's effect was waning, I almost fainted from the pain. If you are susceptible to pain, make sure to let him know so that he can give you a stronger painkiller dose.
A root canal it is going to hurt, regardless of who your doctor is. And if the tooth is infected, it is going to be worse. But as far as my experience goes, Dr. Brough is probably among the best endodontists in this town. I highly recommend him.
