I've only been under Dr. Chi Bui's care for four months, but the transformation is already remarkable. Not only is the change in my smile clearly visible, the correction of my overbite has genuinely improved my ability to chew and enjoy food again. Her approach blends precision, expertise, and kindness in a way that makes every visit reassuring. She explains each step with clarity, pays close attention to detail, and truly cares about long‑term function--not just aesthetics. I'm deeply grateful for the progress I've experienced in such a short time and highly recommend her to anyone seeking an orthodontist who delivers both exceptional results and exceptional care. read more

We were referred to Dr. Bui by my dentist of nearly 40 years, and she has exceeded all our expectations. My son was incredibly nervous about getting braces, but from our very first meeting, Dr. Bui completely put him at ease. What stands out about this practice: 1. Dr. Bui truly takes her time and ensures that the quality of service is exceptional. 2. Every single visit is smooth. Dr. Bui and her staff are consistently friendly, efficient, and punctual.

My son has been seeing Dr. Bui at Orthobee Orthodontics here in Fountain Valley for several years now, and we've had a great experience from start to finish. She has literally watched him grow from a young kid into a teenager, and throughout that time she has been consistently professional, knowledgeable, and genuinely invested in his progress. Dr. Bui clearly takes her work seriously--she's very detail-oriented and takes the time to explain things so we always understand the process. The results so far have been excellent. We're still in the middle of treatment, but his smile has already improved significantly, and it's made a noticeable difference in his confidence. The office staff is also fantastic. Scheduling appointments is easy, they're very accommodating, and communication is great. We really appreciate the appointment reminders by text and phone, and the ability to leave a message after hours is very convenient. It's great to have a practice like Orthobee Orthodontics right here in the Fountain Valley area that we can trust. Overall, we highly recommend Dr. Bui and her team--we're very happy with the care our son has received. read more

My experience with the treatment and Dr. Bui and her staff has been amazing. My teeth look better than ever. I highly recommend anyone that needs high quality orthodontic work done! read more

I'm currently seeing Dr. Bui for aligners, and I've had a wonderful experience so far. Dr. Bui is extremely professional and knowledgeable in her field. She takes the time to thoroughly explain each step of the process and patiently answers all of my questions, which makes me feel confident in my treatment plan. Her office staff is friendly, helpful, and welcoming, and the office itself is clean and inviting.

I have been with them for quite a long time now. They have always been welcoming and nice, and always take care of me! It's been a pleasure being a client of them and I am truly appreciative. read more

I've had a great experience with Dr. Bui and her team! She has been extremely considerate and thorough with my aligner treatment. I have always felt comfortable bringing up problems I was having and she was always able to give me good solutions to those issues. She makes it a point to become familiar with you instead of just trying to usher you out the door which I appreciate very much! I have been incredibly happy with how my teeth have been coming out- which I was skeptical of given that my jaw was an issue in the equation. And more than that her team has been very warm and helpful! read more

Dr. Bui is wonderful. The whole process was easy and my teeth turned out amazing without any discomfort the entire time. I would highly recommend the OrthoBee to anyone. read more

Don't ever go to this lady!! She charged my insurance two years in a row even though we never seen her. My son was got his braces put on and every time he went for his appointments she doesn't do anything for him. This was back in 2021, and now August 2025 she's still trying to send me invoices for late fees for over $1250. If you call and ask for itemized invoices their office works don't speak English. Lady, this is insurance fraud!! I hope you get audit and lose your business. read more

I've been a patient of Dr. Bui for over 15 years: first for braces and then more recently for retainers. She was able to have my retainers made and fitted quickly when I needed them before I left town for a long trip. Dental work stresses me out, but Dr. Bui is attentative and kind, and the OrthoBee office is a calm space. read more

Love this team! Front office is kind and helpful, Dr. Bui is as good as they get. Very happy w my care

I truly enjoy visiting Dr.Bui and her team for my retainer check-ups. She is such a friendly orthodontist. She takes her time to explain everything thoroughly and always provides a friendly, welcoming atmosphere. I would trust and recommend her read more

Dr Bui is a rare find in orthodontics - ethical, highly skilled, and truly devoted to her patients. As a dentist myself, I've seen more than my share of unnecessary or poorly planned orthodontic treatments. That's why I choose carefully when it comes to my own children. I drive over an hour and a half each month to Fountain Valley because Dr. Bui's work is worth it. Her treatment plan has not only perfected my children's smiles but also preserved the integrity and function of their teeth - a balance that takes both expertise and commitment. If you're looking for orthodontic care that combines precision, honest, and genuine personal attention, look no further. Thank you, Dr. Bui, for the dedicated and outstanding care you provide. read more

Dr. Bui is extremely knowledgeable and very personable. She made my twins feel very comfortable despite having to wear these dental appliances over a period of a year due to crowded teeth. My twins are very happy with Dr. Bui and even made reference to Dr. Bui as a super hero by comparing her to Dr. Banner, Dr. Strange & Dr. Who. :) read more

If you are looking for an Orthodontist that will take the time needed to make your teeth right, Dr. Bui is your best bet. She is extremely patient and meticulous and works with all ages. I am 69 years old and needed orthodonture to adjust my teeth after a lower, front tooth removal. The results are incredible and helped me avoid the need for a post and false tooth. read more

My son needed braces so I decided it was finally time for me to do it as well. We were recommended to Dr. Bui and she provided us excellent service. I have completed my braces treatment and my son is almost finished. Love my new smile. Thank you Dr. Bui! read more

Dr. Bui recommended I use Invisalign to correct my crooked teeth. It took about 16 months and my teeth were perfectly straight. During the process, Dr. Bui made sure she saw me monthly and made adjustments accordingly. Thank you Dr. Bui. This has been a huge self confidence builder. read more

if you need help getting your teeth straight go see Dr Bui-she and her staff are awesome!!

Dr. Bui is very considerate and cares a lot about her patients! She is very thoughtful and is a very personable person!

Dr Bui and the OrthoBee were amazing! I got both sets of my braces done by her. Each time, she was very communicative, detail orientated, and understanding in terms of scheduling and if something accidentally broke (because of my mistake of accidentally eating the wrong foods lol). However, what stood out the most from other places was the time that she took to get to know each and every one of her patients! It made it seem that she really cared about my teeth; I was putting them in the hands of someone I trusted. Highly highly highly recommend. It's been 5.5 years since my second set of braces came off, and every time I go back for a yearly check up, she is always welcoming and does a great job. My teeth still look very straight! - Leah read more

Dr. Bui is amazing! She is professional while still being fun to talk to. My teeth look great after completing braces with her. I came back to check up on how I was doing with my retainers. She listened to my concerns and we made adjustments to my bottom retainer so it sat more comfortably. Always a pleasure visiting her office :) read more

I wish I could give 10 stars! I was very apprehensive about teeth straightening. Dr. Chi made the process easy and I have been wearing my clear aligners for several weeks now. They are very unnoticeable and I can already see a difference! read more

I have been seeing Dr. Bui for almost ten years now, and each time I've seen her, she continuously shows her care and expertise towards her patients. I've had my braces/Invisalign off for about eight years now, and every year, she goes out of her way to see me make sure my retainers and my smile are in good condition. I highly recommend Dr. Bui to anyone looking for an Orthodontics consultation. read more

Update: After 3 years, I ljke that my teeth are still straight. Overall, very satisfied.

Thank you Dr Bui ! for inviting me back for check up and tight in my retener. I will recommend to my friends and family.

I am so grateful to have had Dr. Bui as my ortho throughout this process. It was extra difficult for me because I was rarely in town and Dr. Dui was very flexible and worked around my schedule. Dr. Bui is very communicative and took the time to get to know me and what would best suit my needs. My smile looks better now after completing my Invisalign treatment :). read more

During my Invisalign consultation I asked Dr. Bui a question because I was confused ("So Invisalign will take longer than braces?") and she snapped back at me, "I didn't say that, YOU said that." Uhhh I didn't say that either, it was a QUESTION. My mom also went in at a separate time for a consultation for my brother's braces and when she asked about using her HSA, the doctor said, "You know you have to pay for this right?" As if my mom was trying to get out of paying! My mom and I compared notes after our separate meetings and we both felt Dr. Bui had a hostile attitude for seemingly no reason. If you read other reviews you'll see this is a pattern with her. So we decided to go with Family Orthodontics instead for all four members of our family and we couldn't be happier! Dr. Dean's office is so nice and he himself is very clear and kind. His staff is very organized, great about setting appointments. I've had my Invisalign for a year and my teeth look great! They were also much cheaper. read more

Wonderful orthodontist! Dr. Bui is so sweet and makes the best convos. She definitely knows what she is doing and she does it good. She did very well on my smile and made sure it was perfect. I've been with her for a good amount of time now, and I highly recommend going here! read more

Best orthodontist in OC imo!! She is kind and very informative. She did everything by herself and didn't let the assistant do things on my teeth like some other places that I went to. I'm super happy with my treatment :) read more

There is something about Dr. Bui that is truly indescribable, and I highly recommend her. I have been her patient for over 2 years and she has truly transformed my smile. She worked me with me every step of the way and was very diligent in finding the best techniques for my case. I truly felt like Dr. Bui was part of my family for the amount of energy she spent with me. However, I could see that she was like this with all her patients. If you are looking for an orthodontics that strives on perfection than look no further. Dr. Bui is one of a kind and would not accept anything less than perfect as I walked out of each appointment. Which makes her worth every single penny. There is nothing fun about being in your 20's and having braces, but she made each appointment very enjoyable. Lastly, I truly believe that if you love your job you never have to work a day in your life. Dr. Bui is that person who LOVES her job. Which was my gut feeling from the moment that I met her, and knew that she would be able to give me that perfect smile! Thank you so much Dr. Bui & Staff for giving me the perfect smile just in time for my wedding!!! read more

The OrthoBee - Perfect smile for the best day of my life!!!!!! Thank you Dr. Bui!!!! - Orthodontists Near Me - Fountain Valley, California

For years I had been reluctant to get orthodontic treatment because I didn't want braces and had been told invisalign wasn't an option. I had crowding on top and even more on the bottom, and as a musician/performer I was always self-conscious of my appearance. But when I was 23, I consulted Dr. Bui and before long I was wearing my first set of aligners. I'll be 25 soon with my treatment almost complete, and let me tell you, I'm amazed at the results! Dr. Bui is very patient and welcoming, and of course she is excellent at what she does. I used to hate getting dental work done, but now I'm actually excited about our appointments. Her office has a breezy and pleasant atmosphere to it. Ortho is definitely a commitment that takes time, but it's totally worth it. If you're considering getting treatment done, then this is the place to go. Thanks Dr. Bui! read more

I've had the luck to observe and learn from Dr. Bui over the past month and half and would say she is by far one of the few Orthodontist to care so much about her patients. She is prideful of her work and helps you reach the goals you want. I've seen her get excited with patients when treatment is over and celebrates with them on the journey they went through together. She creates individual bonds with each patient and makes sure they feel welcomed and safe. If you are looking for the best doctor to invest your time, money and smile on it's Dr. Bui. read more

From the consultation, treatment, and to the retainer stage, Dr. Bui has always been thorough and attentive. She is always communicative about her suggestions and the other options/routes patients can take. Not only is she diligent with her work, but she also takes the effort to get to know all her patients on a personal level. I always recommend her to family and friends when someone I know is looking for an orthodontist. As a patient since 2011, I've only ever had the utmost positive experience with Dr. Bui and her staff. read more

Amazing top to bottom! It's hard to find a medical professional that works so well with children on the Autistic spectrum. Dr Bui put my 16 year old daughter who had Autism at ease immediately. We've waited awhile to put braces on due to extreme oral sensitivity issues. Today Chloe is more than ready and actually excited. My hubby and I are both RNs and we can recognize a tremendous doctor when we see one. You'll love her, parking is easy, she serves yummy Vietnamese coffee, and the music is actually good too! Give her a try! read more

The OrthoBee - Orthodontists Near Me - Fountain Valley, California

I am a ortho patient of Dr. Chi Bui. I am currently half way into my clear aligner treatment (Spark) and I am already thrilled by the result thus far, all thanks to the treatment and recommendation of Dr. Bui. I have moderate overbite with an implant on one of my two incisors from an accident. I went to many orthodontists trying to get my teeth straightened and they all refused to give me treatment because of my implant (which is fixed, so not much could be done to fix my smile). I went to Dr. Bui and she gladly accepted me as her patient. She closely followed up with me and gave me recommendations on how to improve my smile. Her assistant is also very nice and she works around my schedule so I could . I'm very happy with the result at this time and can't wait to see the final result at the end of the treatment! read more

This was my second time getting braces (I had braces in high school). As an adult whose teeth were no longer straight due to losing my retainer years ago I searched for an experienced orthodontist who was easy to communicate with, knowledgeable and has reasonable prices. Her practice is very clean and presentable. Dr. Bui was the perfect fit. I only had to wear braces for less than a year and I am so happy with my perfect smile thanks to Dr. Bui and her friendly staff. read more

My daughter has been seeing Dr Bui for almost 2 years now and we are so lucky to have found her! She has always been patient and kind with my daughter. She also always explains everything in detail and keeps me updated on her progress. I trust her so much! read more
