Services
I am Dr. Tim Myoungsoo Choi, and it is certainly my pleasure to serve Katy, Cypress, and the Greater Houston area. I was born in Seoul, South Korea, and immigrated to the United States 15 years ago with a passion and solidified dreams to become an orthodontist. Before becoming an orthodontist, I was a general dentist in Gangnam for 11 years.
While you wait to be seen, please enjoy our complimentary hot coffee, tea and water cooler. We also have an iPad station for you to use during your wait. We use only the latest technology in digital x-rays, which requires 80% less radiation than conventional film X-rays and also reduces the creation of hazardous waste materials.
Traditional metal braces use constant, gentle pressure, which over time, move teeth into their proper positions. By the age of 7, the first adult molars erupt, establishing the back bite. During this time, an orthodontist can evaluate front-to-back and side-to-side tooth relationships. Many teens get their braces during this time!
Invisalign takes a modern approach to straightening teeth, using a custom-made series of aligners created for you and only you. These aligner trays are made of smooth, comfortable, and virtually invisible plastic that you wear over your teeth. Dr. Choi will take x-rays, pictures, and impressions of your teeth, which Invisalign will use to create a digital 3-D image of them.
Clear braces are another option for those who want straighter teeth but would like to minimize the appearance of metal on their teeth for a more natural appearance during their orthodontic treatment. Clear braces are made out of a translucent polycrystalline ceramic that blends with the color of your teeth!

I am very happy that I decided to get my children’s braces here. They answer any question that my kids or I might have and are very fast at returning my calls or my texts when I call after hours. Thank you so much for your time and help and for making my family feel very comfortable here.

Thank you Cornerstone Orthodontics for following COVID-19 safety protocols and helping me feel safe. I can always count on the Cornerstone Team to prioritize patients and meet their needs even in these scary times. The social distancing guidelines that the Team implements are extensive: they disinfect the doorknobs and chairs after each use and have installed sneeze guards to protect patients and employees. Furthermore, all employees are required to wear a gown and mask which helps me feel more assured.

I love how clean and bright the office is! That was the first impression I had when walking in. Another reason I chose to start treatment with Cornerstone Orthodontics, was because D.Choi was very knowledgeable and provided me with a couple of treatment options and explained every detail! The staff is also very friendly and welcoming! They also have great payment plans! I just loved my experience.

He only knows our family from his wife, but he gladly checked up on me for free on Saturday afternoon which is not even his work time! His kind manners and intelligence told me without doubt that he is a professional. I had a great experience in Cornerstone Orthodontics and I would gladly give it five stars!
