John U Choi, DDS PhD

I am not very happy with the service fee. I found dr. Chio on Unilocal and base on what I read about his reviews, education, & experiences. I think he might be the best dr. I need to talk about my gum graft. so I decided to call and made the appointment. I talked to Nacy (receptionist) and she told me the consultation fee is $ 99. I went in dr. Chio dental office today for my gum graft consultation. Dr. Chio examined my full teeth, took front teeth x-​Ray, took photo of my front tooth & described what treatment is best for me. When the consultation is finished, they charged me $ 170 :(. The reason I am not happy because cost for consultation that they charged me ($ 170) different from what they told me ($ 99) at the first place. Other than that, my experience with dr. Chio was great. He looks and sounds very educated about his dental field. He explains everything to you and provides the best option for your treatment.

I was a crying mess when I first went to Dr. Choi, having learned from my dentist I had a gum and bone infection that would eventually take my front tooth. Being a girl in her 20’s, the thought of having no front tooth, needing surgeries, and fake teeth was horrifying.
Dr. Choi’s treatment approach treated the infection and we even saw some of the bone I lost regenerate on its own during my last check up. While the other 2 dentists before him recommended they extract the tooth right away and get started on bridging it, Dr. Choi’s patient and steady treatment approach saved me from being over-​treated. His Ph.D. background makes him extraordinarily special as well – he makes evidence-​based decisions and is up to date with the latest scientific studies. I thank my lucky stars that I landed in his office, instead of someone else.
Every single one of his staff members are amazing as well. During my first appointment, I came in scared and crying but left with a sturdy feeling of having the support of the whole team behind me.
I’ll continue to go to him for as long as he’s practicing, and would recommend him to my family, friends, and anyone in need of the best periodontist ever.

Dr. Choi has performed several surgeries on me over the years, some of them quite extensive. Besides receiving the high quality of his work, I have yet to use any pain killers (prescription or OTC) afterwards, which is quite remarkable.
Dr. Choi is the best periodontist/​oral surgeon I’ve ever encountered and his office staff is extremely efficient and friendly.
No one I know looks forward to going for dental work. Dr. Choi and his staff remove that dread.

In my lifetime, I’ve had six oral surgeries. Despite this, I am the biggest chicken when it comes to any type of procedure. I had my graft done by Dr. Choi last November and wow, that man is a genius. His staff is great too, by the way (made me feel less nervous about everything). In any event, the technique Dr. Choi used left me without pain, at all — even after the numbing went away. I was amazed. I hope I never have to do it again but if I do, Dr. Choi will be the only person I want doing it. Even if I lived in another state I would fly to Fullerton, that’s how great he is. He also is very professional and kind and makes you feel at ease.

I drive an hour to get to Fullerton every three months to see Dr. Choi. He is caring and a wonderful Dr. His staff are all the best too. I have always dreaded going to the Dentist but now it is so much more enjoyable.
He is worth the drive!

Dr. Choi came highly referred to me by a good family friend. I have to say that he exceeded my highest expectations with his professionalism and quality. He did an excellent job and I would drive a long way just to have him do my surgeries in the future. He even gave me a personal call later in the evening to see how I was doing!

Dr. Choi is a superb periodontist. He is kind and quiet as a person and has extremely high standards as a surgeon. I have had extensive work done by him as I have had periodontal disease. I wouldn’t go to anyone else, ever!
