Excellent dentist. I've tried many since moving to OC a year ago. Jennifer & Haley are a wonderful asset to the office. Friendly, professional with a great sense of humor. Dr. Choi is gentle and explained my concerns very clearly. This made me feel extremely confident that I was in good hands . read more

I thank God for Dr. Choi's help. I went to Dr. Choi seeking emergency treatment for 2 failed bone grafts, maybe 3, as I was in an unbearable state of pain & discomfort. After going to 2 maxillofacial dr.s who, basically, ignored my pain but one took $8,000 for torai removal, I was desperate. My prior periodontist also did not want to act, too busy, no empathy. Dr. Choi removed the infection from 2 sites so far. He is methodical, not prone to rushing, as I like. read more

Thank you Dr. John U. Choi and your staff for being the wonderful dentist that you are and for us basically paying nothing for your time and expertise. We really appreciate only paying for the materials to help repair my son's congenital birth defects. The fact that you let us make payments along the way for the many visits we have made to your office in this life altering dental procedures. Someday my son and I both hope to be able to pay it forward to someone else in need. You are truly a special human being and may God bless you and your family! Marcia B. read more

great care but he talks too much details. I am an engineering manager so i am use to managing too much information but it can be a challenge with John. His staff is excellent, i also see his dental hygienist, great work. i do recommend read more

The best cleaning I've ever had! my Hygienist was awesome! loved how Dr Chou gave me options to better help my Dental health! His office in the best I've had in over 20 years!!! read more

First I would like to compliment the staff and assistants to Dr Choi. Next, the Office administrator (Diane) was wonderful. Finally, as much as I sometimes found Dr Choi accessible, I didn't find him emotionally available when I would need more answers to my questions answered. He wanted to talk about how much he knew instead of trying to appreciate my anxiety. I drove an hour for his practice and I don't think he ever comprehended that it was a minimum of two hours just to come and go. He once told me that I'd have to come back for a simple measurement for my "guides" due to the office lunch hour. Another time, I patiently waited an hour in the patient's chair to be told a mysterious story? I never like to write this type of review, however, when you're having this extensive surgery/restorative work projected to be done over a year, pick someone that you have a really excellent repoire. read more

I suppose Dr. Choi is as good a dentist as you get for gum disease, but he took me to the bank and over charged me a lot. It's not good when a dentist gives you an estimate for gum surgery and then after the surgery charges you thousands of dollars more than the quote you agreed on. read more

Honest and knowledgeable. I trust what he's telling me. I've struggles to find a surgeon who is not recommending procedures that I don't need or that didn't try to rush things. I do feel like I'm in good hands. read more

Dr. Choi seems like a good dentist until you need a procedure. Their cleaning felt like a jackhammer in my mouth. My gums still hurt and it has been many months since I have had it done. Then he told me I had gum disease. I went to see an amazing periodontal specialist. He told me I have a problem on one tooth and not to worry I take good care of my teeth. He questioned Dr. Choi and asked me why he would put me through so much pain if I didn't need it? Anyways. I am so thankful I found my new periodontist. He is amazing and I trust him with the work. read more

7 years after first meeting Dr Choi and his staff, I'm still in great hands and care! I moved out a bit further from Fullerton but still make the trek from Santa Monica every 3 months to keep my cleaning appointments. That's a testament to the care and attention I get at his office. read more

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!! read more

Dr. Choi, a Periodontics Practitioner, is the most skilled professional I have the the occasion to visit. Actually, after multiple visits over multiple years, I can unequivocally recommended Dr. Choi. My husband had many bad dental experiences growing up and after he visited D. Choi, his fears left and he greatly appreciates Dr. Choi's kindness and his skillful, gentle touch. Dr. Choi oversees all of our dental needs and has a wonderful, highly skilled, teeth cleaning staff. From reception through all phases of treatment, Dr. Choi and all those who work with him are just excellent and of high caliber. read more

Dr. Choi has gone above and beyond for me and my extremely complicated case, something few dental providers would have taken on. Other dentists were quick to suggest extractions for multiple teeth, but Dr Choi believed this was over treatment and saved my teeth. He is easily the best in his field! His staff is equally as awesome! read more

Dr. Choi is an incredibly talented oral surgeon. He's almost done reconstructing my entire mouth with gum surgeries and I couldn't be more impressed. Mine was a very severe case (very bad recession despite being only 29 and never even having a cavity in my life, thanks for the genes mom and dad) and he tackled it when no other periodontists I visited would even attempt traditional gum grafting. He takes his job incredibly seriously and wants the absolute best outcomes for his patients. Plus, the entire staff is very kind and helpful! Just a delightful office that takes COVID precautions seriously. I can't recommend Dr. Choi enough. read more

I have been Dr. Choi's patient for a very long time, at least 15 years. I have had many surgeries with Dr. Choi (maybe 10 or so) from gum graft to implant to tooth extraction. Dr. Choi is the kindest, most gentle, most educated, and the best dental surgeon I have known. This means a lot given the fact that I have gone to many dentists, specialists because of my dental issues. If you need a periodontist, look no further. Give Dr. Choi's office a call, you won't regret! read more

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! read more

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! read more

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. read more

Dr. Choi is a wonderful Periodontist. Very gentle and caring. He takes the time to thoroughly explain treatment and made sure I understood my treatment. I did not feel rushed. The staff is wonderful and made me feel comfortable. I definitely recommend Dr. Choi to my family and friends. read more

I have been a patient of Dr John Choi for many years. He has performed many gum graft surgeries. My results have been excellent. He has gone out of his way to deal with my allergies and high risk issues and really emphasizes prevention. He is meticulous, perfectionistic and at the top of his game. I also love his staff, particularly his hygienist Judeen who cleans my teeth every two months...the end result of all the care is that I am maintaining my gum health thanks to this office. read more

One of the nicest and kindest oral surgeons I ever met. Gentle touch, healing was just as he said an I am doing great. Highly recommend him

Dr. Choi was very conscientious of my need. The surgery he performed was over 2 hours long, and yet he was steadfast in his procedure. My recovery was slight, and barely noticeable. I highly recommend Dr. Choi for any major work that needs attention. read more

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. read more

Dr. Choi is an outstanding periodontist who takes his craft very seriously.

After giving my unique situation careful and thoughtful consideration, Dr. Choi did an excellent job! He is skilled and thorough and I highly recommend him. read more

I've left my gum disease untreated for years and feared walking into an office only to hear devastating news. The experience I've had with this office definitely leaves me in tears, but happy tears. Dr. Choi is such a fantastic periodontist. He is so kind, caring, and gentle with his evaluations. He takes on a new approach for me that no other periodontist has ever tried. When I first met him, he stated that he wanted to learn the biology of my mouth and how it responded in time with treatment and better care, before jumping into surgery. What a wonderful way for him to care for his patients. His approach makes so much sense and resulted in a dramatic improvement of my condition. He has yet to recommend any further treatment plan as he still wants to review any additional progress, which has already resulted in less surgery for me. I can actually say that I look forward to seeing him as every time it has been with good news. I couldn't be at this comfort level of treating my gum disease without him, or my hygienist, Kathy. They are a blessing to me and I am so thankful that I found their office for treatment. Nancy in the office is also top-notch! She's really on top of things and super friendly. I enjoy our small chats when I visit; she is so inviting. I fully recommend this office for anyone who suffers from gum disease and needs the level of gentle care that I personally understand. read more
