I had to make an emergency visit to Dr. Cohen after my first endodontist failed to get me numb (the guy even said I needed to see a neurologist). Dr. Cohen's office got me an appointment right away, prescribed a sedative (which i did not end up needing), but most importantly, he did a fantastic job on my root canal. He explained every step of the procedure very clearly. I normally have a really, really difficult time at the dentist's office because I hate drills and don't get numb easily, but this procedure was virtually painless. I am eternally grateful to Dr. Cohen and his staff.
