I would highly not recommend this dentist for any kind of dental work. I had a root canal and was very nervous about it since I have never had a root canal. The first shot that numbs the tooth and gum area didn't numb well then the second shot still didn't take well finally a third shot helped. While the doctor was drilling I started to cry from the pain of the shots and I started to feel the drilling that the doctor had to stop. After two weeks of having my cap put on where the root canal was done, the cap fell off while I was eating. I went back and the doctor glued the cap back on. Four months later my cap fell off again. I plan to find another dentist to repair the work that was not done correctly and poorly by Dr. Ian I Cho. I also bought their tooth paste and mouthwash brand. My teeth started hurting as if I needed more dental work. I then stopped using their product and the pain went away. I would not recommend their product either.
