Grand Mission Dentistry

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.

What an incredible experience at my dentist's office! From the moment I walked in, I was impressed by the excellent customer service and welcoming atmosphere. The use of cutting-edge technology made my visit quick and efficient, respecting my time as a patient. Additionally, the team goes above and beyond to make you feel comfortable throughout. I want to especially highlight Karen, who attended to me during my latest appointment. Her professionalism and friendliness made the experience even more enjoyable. She's definitely an MVP at the office! I highly recommend both Karen and the dental office to anyone in the area. Stop searching and visit this place, you won't regret it!

The front desk, Dr. Nguyen and Shantal were super sweet and helpful. I didn't catch the name of the woman at the front desk but i wish i had because she was really informative and set the experience on a positive direction from the beginning. I was nervous going in and they made the experience great 👍 also, Diane at check out is amazing. Shout out to Angela for being the best 🔥 I appreciate you!

Been coming here with my family for 8+ years. Met Jossie at the front desk. She educated me on teeth whitening process and loaded me so much information, that is unbelievable. I cannot thank her enough and Granberry Dental, dentust, the manager, and the staff.. Keep up the good work.

This dentist office has given me the best experience ever!!! From the dental assistant Zara, to the hygienist I seen last week and Doctor M all did an amazing job!!! I have dentist phobia and they made me so comfortable, they have high quality equipment, everyone in the office is so pleasant and friendly!!! This dentist isn’t even in my insurance network and I still will choose them every time!!! After years of being anxious at the dentist I’m finally comfortable 💜🙌🏾

Visiting the dentist can often be an experience filled with anxiety and discomfort, but my recent visit to Grand Mission Dentistry, specifically with Angela, transformed that stereotype into a remarkable and pleasant memory. A Wonderful experience.Everyone in office is nice and helpful. Special acknowledgement for Angela who did amazing with my cleaning. She took the time to thoroughly explain each process from the simplest cleaning to more complex treatments, ensuring I understood every step. Her amazing skills, coupled with her gentle approach and patience, make dental visits for me far less daunting. She is highly recommended ! 🙂

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.
