I had two root canals done here and I have to say they truly are experts. The most pleasant experience I have ever had during a root canal. I felt no pain and the dentist was very understanding from the beginning when I told him I had a high tolerance for all pain medication so I would probably need more than the average person. I was referred here by my regular dentist so I think all appointments require a referral. They only do root canals here. I was treated by Dr. Shimizu but I know all the dentists are well qualified. The front desk staff is friendly and they offer snacks and drinks while you wait.
