Referred to him by my regular dentist for a difficult root canal. I was extremely stressed at the thought of a root can as I hate pain! He was wonderful, told me everything he would do then talked me through it step by step. There was no pain during the process, which was so quick, and just a tiny bit of soreness for a couple of days and then none. I totally recommend Dr. Cohen and his staff, which was very pleasant and helpful, anytime you need this service. You won't regret your decision. Dr. Cohen followed up the root canal by a personal call that evening to make sure things were OK, which they were.
