I had a root canal on tooth #29. Dr. Altshul was very reassuring and very gentle. They numb you up like crazy. I had pain the following day, but before I could call the office, they called me to check on me. Prescribed pain meds and an antibiotic. Definitely would recommend Dr. Altshul to anyone needing a root canal. Also, they always use a microscope which gives them a higher success rate.
