      • "There is something about Dr. Bui that is truly indescribable, and I highly recommend her. I have been her patient for over 2 years and she has truly transformed my smile. She worked me with me every step of the way and was very diligent in finding the best techniques for my case. I truly felt like Dr. Bui was part of my family for the amount of energy she spent with me...Dr. Bui is that person who LOVES her job. Which was my gut feeling from the moment that I met her, and knew that she would be able to give me that perfect smile! Thank you so much Dr. Bui & Staff for giving me the perfect smile just in time for my wedding!!!"

      • "For years I had been reluctant to get orthodontic treatment because I didn't want braces and had been told invisalign wasn't an option. I had crowding on top and even more on the bottom, and as a musician/performer I was always self-conscious of my appearance. But when I was 23, I consulted Dr. Bui and before long I was wearing my first set of aligners. I'll be 25 soon with my treatment almost complete, and let me tell you, I'm amazed at the results!"

      • "At 51, I was reluctant to start an orthodontic program. For many reasons I had put this off for years (E.g. Age, effect on speech- lisp, visual appearance). But, Dr Bui was so helpful and positive I felt comfortable enough to take the leap. So, I just started invisalign today. And, I decided to do propel as well. I can't believe how quick this whole program may be done!"

      • "Amazing top to bottom! It's hard to find a medical professional that works so well with children on the Autistic spectrum. Dr Bui put my 16 year old daughter who had Autism at ease immediately. We've waited awhile to put braces on due to extreme oral sensitivity issues. Today Chloe is more than ready and actually excited. My hubby and I are both RNs and we can recognize a tremendous doctor when we see one. You'll love her, parking is easy, she serves yummy Vietnamese coffee, and the music is actually good too!"

      • "If anyone would like to take recommendations for perfect smile, I would love to introduce Dr Chi Bui. You don't need to wait for a long time to see if any problem happens during ur challenge or wasting time for arranging appointment. It would be so quick and save time for u if u choose that service over there. Every appointment would be reminded early 2 days, so u don't need to mark on the phone or on ur note."

      Frequently Asked Questions

      Braces use steady, gentle pressure to gradually move teeth into their proper positions. The brackets that are placed on your teeth and the archwire that connects them are the main components. When the archwire is placed into the brackets, it tries to return to its original shape by applying pressure to move your teeth to their new, more ideal positions.
