Services
Braces
Braces correct misaligned teeth and jaw issues through customized treatment plans. We offer various styles including traditional metal, ceramic, and self-ligating options to suit different lifestyles and aesthetic preferences. Our experienced team ensures optimal comfort and effectiveness throughout the treatment process.
Clear Aligners
Clear aligners provide a discreet alternative to traditional braces using removable, transparent trays. This treatment gradually shifts teeth into proper alignment while allowing patients to maintain normal eating and oral hygiene routines. Ideal for teens and adults seeking aesthetic solutions.
Two-Phase Treatment
Two-phase treatment addresses orthodontic issues in children through strategic intervention during jaw development. The first phase creates proper space for permanent teeth, while the second phase focuses on final alignment. This approach prevents future complications and ensures lasting results.
TMJ/TMD Treatment
TMJ/TMD treatment alleviates temporomandibular joint disorders through customized orthodontic solutions. We address symptoms like jaw pain, clicking, and headaches by correcting bite alignment and muscle imbalances. Non-invasive approaches prioritize long-term comfort and functionality.
Sleep Apnea Treatment
Sleep apnea treatment utilizes custom oral appliances to maintain open airways during sleep. This orthodontic solution addresses mild to moderate obstructive sleep apnea by properly positioning the jaw and tongue. Patients experience improved sleep quality and reduced daytime fatigue.

The office do their job. Average interaction with customers as most of time when I visit the the office or talk to them on the phone the conversation is often ended cold, it feels like you're been brushed off. Maybe the staff is busy? So far all the interactions I had with the front desk, finance, inside staffs, except for dr so made me feel this way.

Poor attention to detail. We expected a lot more going by yelp reviews and Dr So's credentials. Dr So did a mediocre job. Our child isn't happy with the results. The office does not let you wait in waiting area since covid, which means you have to wait in car for however long it takes. That's fine if we were unvaccinated. It would be all worth it had the actual job been phenomenal.

My dentist referred me to Dr. So in to have her check my bite and address some cosmetic concerns. I had major mouth surgery 30 years ago, and braces, along with extensive dental work over decades, so she was interested. She took a panoramic Xray and examined my bite and gums. Discussing my history and my concerns, she made some recommendations, none of which required her services. To my surprise there was no charge for her most professional services.

I would really love to give this orthodontic office five stars, but I need to be honest. I think that my child did receive professional care when it came to the technicalities of braces but unfortunately the communication from the staff was poor over the 4 years that we have been there. For example, I would leave a message in the general mailbox and rarely get a call back, I would have to get lucky and call when somebody would answer to get the information I needed. Also, some of the employees over the years at the front desk were lukewarm with their reception at best and seemed inconvenienced at times when I needed help.

I very rarely heard from anyone if there was something important going on with my kid's braces, I would have to try to get a hold of them to be in the loop. Most professionals would let the parent know about any pertinent information. I will be taking my other child to a different doctor for his braces.
