I won't recommend any my friends to Dr. Yun. I once had a cavity filling in her place. My cavity was too deep and the best option should have a root canal. However, she was not totally honest to my teeth situations because she didn't want to give up earning my money. She is not a root canal specialist. But she just filled the cavity without telling me that actually I needed a root canal not filling. The whole process was not pleasant. I felt pain immediately after the filling. It was a horrible experience i ever had considering that I got a useless filling with an expensive bill. Also the final cost was still 30 bucks higher than the number they gave me when I firstly called them. The assistants are nice there.
