Grand Mission Dentistry

A Thorough​Conservative Dentist In Richmond TX

At Grand Mission Dentistry in Richmond, Texas, Dr. William Sung believes in giving patients a thorough evaluation of their oral health. Here, it’s about much more than just treating a tooth – it’s about informing our patients how their medical history, diet and habits have an overall effect on their dental health. He tries to find the source of the issue and not just treat the symptoms or results.

Providing a family oriented environment, board certified Richmond pediatric dentist Dr. Tam Nguyen provides gentle, friendly care and treatment to children.
The knowledgeable and friendly staff at your local Richmond dental office can provide you with both quality and exceptional dental care.

Whether you’re in need of a teeth whitening, a cosmetic procedure or emergency dental care, Dr. William Sung is dedicated to providing attentive, friendly care in a relaxed environment. We invite you to come visit us at our dental clinic today!


Our Goal Is Comprehensive Health

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 effect 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.

My first experience at Grand Mission Dentistry was great! Everyone in the office was very polite and professional. My hygienist Karen did a great job and Dr. Sung answered all my questions very thoroughly and gave tips for some of the issues I had like gum sensitivity. Will definitely be coming back!

These guys are the amazing! Karen did an amazing job as my hygienist and made sure I was comfy and relaxed along the way. Dr. M offered me a lot of insight and gave resourceful recommendations.

My wife and I moved to the area about 2 years ago and have been trying to find a dentist that we really feel good about, and we're so happy we found this place. Karen and Dr. Sung are great! We had bad prior experiences at other places where they either don't provide enough attention and miss issues with your dental health or try to upsell you on anything they can. But Dr. Sung and his staff are so professional, friendly, and provide excellent care that we can trust.

My husband and I have been coming here since 2018. Dr Sung and his team-are wonderful. All the hygienist have been friendly and great. Love that I never have to wait past my appt time. They have Netflix to watch while teeth cleaning. I tried the Airflow machine today and liked it because it was gentle on my teeth and used warm water. Thanks for always being great and consistent.

Highly recommend Karen. She was the nicest hygienist I’ve ever met. I get nervous every time I go to the dentist but she made me feel so comfortable through the whole process. She took time and explain everything to me about my teeth. Would definitely be back!!

Fun For The Whole Family!

A lot of general dental practices don’t allow kids when their parents visit the dental clinic for having a consultation or treatment procedure. At Grand Mission Dentistry, we are glad to see your entire family including children. We recommend they visit us as soon as their first tooth erupts.

Our team is friendly, gentle, and eager to create an environment of fun and learning. We are also happy to offer family appointments so that you can get your whole family in and out in a single visit.
