“Dr. Nguyen is great and caring. His staff is always wonderful, helpful and accommodating. Smile Design Dental is a family dentistry that is great for people of all ages with great hours of operation! My daughter recently had her braces removed...most beautiful teeth ever...Yay to the yay for Smile Design Dental in Plano!” Elizabeth B., Plano, TX

“Dr. Nguyen and his entire staff are the best! My children and I have been going here for our dental work for more than a decade and not even once have I felt that I didn't get the best genuine treatment by Dr. Nguyen and his staff.” To-Anh Huynh R., Plano, TX

“I had a filling that fell out. Called right away. Got in for a noon appointment same day (1.5 hours from calling in). It took a few minutes to assess the tooth and about 25 minutes to complete the work. Awesome service! Super friendly staff!!! Recommend to anyone looking for an amazing dental experience.” Brenda R., Plano, TX
