I enjoy going to Dr. Wu's office for my routine cleaning. I don't have dental issues. Many thanks to Dr. Wu. I have been going there for over 20 years since I came to the bay area. He is reliable and patient. I have experience with some aggressive dentists who liked to drill holes in clients' teeth and fill them up. I always consult with Dr. Wu. He does not recommend any unnecessary procedures unless it is needed to keep my teeth healthy. It is very hard to find another dentist as trustworthy as Dr. Wu.
