Our Mission

Dr. Sung learned to look at dentistry differently. Instead of just “fixing teeth”, we take your whole body health into account. Diet, medical history, medications and habits can all have an affect on your oral health. And it goes both ways. The state of your oral health can have a huge impact on the rest of your body. Dr. Sung is trained to see these connections, and find the right solutions to keep your entire body healthy, happy and smiling.

We’re proud to offer the local communities of Richmond, Katy, Rosenberg, Sugar Land, and the Greater Houston Area a more comprehensive option for their dental care. Come to Grand Mission Dentistry for patient education, comprehensive care and treatment, and compassionate doctors and staff whose mission is to make you smile!

We want to help you identify and understand the best dental treatment option for you and your family. At Grand Mission Dentistry, we value each one of our patients as one of our own. Our goal is to make sure that you understand the importance of your oral health. We hope to help you learn more about our dental office and the comprehensive range of dental care services that we offer.
