I just had a root canal by Dr. Scianamblo and it was done perfectly. Everything he did was great and he saved my tooth. This is my second root canal with Dr. Scianamblo and my husband has had 3 root canals with him. Everyone in is office were very professional and that includes Diane. She handled everything correctly for us . My husband had a root canal by a different Endodonist in San Rafael who did not do it correctly which caused the root canal to fail. Dr. Scianamblo tried to save it but was unable to. The tooth was badly cracked and he had to remove it surgically. My husband had very little discomfort and took only one pain pill. I had no discomfort after my root canal that took 2 hours. I did not need any pain medication of any kind. This Doctor is the very best. My husband regrets that he let his regualr dentist send him to a different Endodontist in Marin. That will never happend again.
