I've never had such a painless root canal in my life. Dr. Cohen knows what he's doing and gets it done. The staff are all super friendly, while professional. They squeezed me in as I was in so much pain, and since I had to wait a few hours from the time I was examined to when he could begin the root canal, the staff actually looked up a spa I could go to for some chill time. So nice. Yes, they are expensive, but if you have a tough root canal, this is the place to have it done. Hands down.
