About Kai Orthodontics

Complex cases like double jaw surgery and overbites corrected ahead of schedule, with emergency fixes like a 3D-printed retainer turned around in a day.

Kai Orthodontics handles a range of complicated cases, from a double jaw surgery coordinated with an outside surgeon to a significant overbite corrected faster than the original three-year estimate. Reviews often mention how quickly the office responds to problems, replacing a lost retainer with a 3D printer within a day and fixing broken brackets or wires within days rather than weeks. Dr. Kevin Kai and Dr. Alan Kai, who now run the practice, are described as explaining treatment options clearly and coordinating with outside providers when surgery is involved. Several families mention bringing multiple children through treatment here over the years.

Super happy with my results! I had terrible overbite originally along with pretty lopsided teeth but after two years only, all my issues were fixed. I was expecting at least three years but it was fixed very quick! Staff are all very friendly and very time flexible too.

I had asked my dentist for a referral to an orthodontist as over the years my teeth had shifted after having braces during my teenage years. Imagine my surprise when he referred me to Kai Orthodontics. Dr. Kenneth Kai had been my orthodontist the first go around! When I went in for a consult, I learned that Kenneth Kai had recently retired and his sons were now running the practice in the same office I had been to as a teenager. Drs. Alan and Marcus are amazing! Both of them always took the time to explain every step of the process when I decided to go with Invisalign. I was very pleased with the whole process. Also, the office staff and technicians are top notch, very personable, and extremely knowledgeable. I highly recommend Kai Orthodontics!

Dr. Alan and Kevin are always super knowledgeable and helpful. They have made the process for braces so easy, and even if something doesn't go exactly right (brackets breaking), they are always patient and kind when they have to replace them. I feel like every time I visit them, they and the rest of the office are welcoming, and I learn something new about the process. I actually kinda look forward to my appointments even.

Amazing experience with Kai Orthodontics. Everyone from the front desk to the assistants and Dr. Kai is always so kind, welcoming, and professional. Throughout my braces journey, they have always taken great care of me and helped me every time something happened with my braces or wire. I truly appreciate their patience and kindness. Highly recommended!
