My child has an extremely high pain tolerance, and very seldom cries or even winces in pain, even when bleeding. During treatment, my child was screaming and crying in pain. Dr. Gordon said "I know it doesn't hurt". I know that it did hurt, badly. The rest of the procedures were going to be rescheduled for another time, and it was recommended that my child be administered sedative medication before beginning treatment (not covered by ins). Subsequently, we went to a different pediatric dentist and had a wonderfully pain free and pleasant experience.
I did, however, find Dr. Gordon's staff very nice.
