Sienna Modern Dentistry and Orthodontics not only serves the Missouri City area, but the neighboring communities of Sienna Plantation, Dewalt, Trammels, Teal Run, Riverstone, Lake Olympia, and Quail Valley. We know it's important to find a dentist you can trust nearby, so please check us out if you're looking for dentists in the 77459, 77489, 77545, and 77479 areas. We're on the southwest corner of Hwy 6 & Sienna Pkwy, in the Sienna Plantation Shopping Center, near the HEB. We believe in supporting our community and proudly provide monthly promotions to give back to the community. Our team also serves the community by participating in Smile Generation Serve Days where community members who would not otherwise have access to dental care are provided with free dental treatment and Dr. Cao donates a "Smile Makeover" each year.
