    Dear Dr. Christopher Nguyen,…read more Words cannot fully express how grateful our family is for everything you have done for our daughter Tuong-Vi Mai. Your work with her braces and treatment not only improved her teeth but also you have gave her back her younger look. Seeing her underbite corrected and her smile transformed has meant so much to our family. My daughter is gaining confidence and comfort back with her younger look again. We truly appreciate the time, dedication, patience, and kindness you showed at each every visit. You have provided our family all the needed supports, tireless efforts, and your valuable recommendations to the best jaw surgeon. You walked us through all the processes of getting approval from insurance for the underbite surgery. Without you help, we could not get all the things done beautifully to our daughter's smile as today. My family is also want to sincerely thank to all of your staffs at your office for incredible care, skills and patience which my daughter had received durning the course of treatment. Again, thank you so much, Sir. Kelvin Mai

We didn't remove the braces until both doctor Chris and I are happy with the results. My teeth journey took a bit longer until end of 2025 because I needed more work done. I got a bone graft and tooth implant at a different DDS location and the doctor there also complimented my straight teeth and bite. The whole process costed a lot of money and time but overall it was worth it.

    HANDS DOWN, best ortho office in all of OC!!!…read more Sons & Daughters orthodontics is a highly-rated (now we know why) ortho practice in Irvine, by The District at Tustin Legacy. They are known for using modern technology and offering services for all ages ~ children, teens, and adults, such as Invisalign or your traditional braces. Dr. Lee, Dr. Nguyen and their whole staff are so pleasant to interact and work with. They truly care about each and every one of their patients, young to old. They are super friendly and very efficient. The ortho office has a modern, ultra cute & chic aesthetic. Very inviting & sterile clean. Both my kids get their orthodontic needs (braces) here. My teenage son choosing the traditional braces option and my teenage daughter opt'ing for the newer Invisalign technology. Such a vast difference from the days when I had braces. Lol Wish I had options like these and not having to gag every time I had to have an impression made of my teeth. IYKYK YUCK! Now they have cool camera wands to do all that..like what?!?! Considered myself mind blown. My son actually just graduated this past week, after 2 years of wearing braces (I can't tell you how stoked he was for this day & to ring that bell lol) and his beautiful smile says it all. The newfound straight smile evokes such a renewed confidence in him. It's the best feeling & sight to see. My daughter will be next in less than a month.

I'm planning to take her soon and I know she will be in the very best of care. They have modern technology and the nicest staff, I was so impressed!

Because I decided to go with the initial removal and replacement of the retainer, I called to make an appointment with Yancy, the assistant that I spoken to previously regarding the options. Her entire demeanor changed when I called to schedule the appointment for the lesser expensive option, she acted like it wasn't worth their time, I wasn't an important patient anymore, like it was a hassle just to schedule an appointment. I literally felt like I was wasting her time. I called back the same day to cancel my appointment and am currently looking for another orthodontics center to perform the wire fix. EDIT: I'm editing my post that was once a 1-star review. Yancy called me to apologize. She assured me that they were there to assist me on whatever option I choose in regards to the correction of my retainer. At this time, I have booked another consultation with different orthodontist and I let her know that if things feel through with them, I would give her a call back. Thank you for calling me!

    I'm so grateful I found Dr. Youssef at FitSmiles Orthodontics. I've had braces twice before, and…read morehonestly, I never thought my teeth could look this good. The transformation with InBrace has been on a whole different level. From day one, Dr. Youssef showed me 3D imaging of what he could do with my smile, and he ended up delivering exactly that--actually better. He pays attention to every detail: alignment, bite, angles, and even how everything affects the balance of your face. I get compliments all the time now, which still surprises me! What makes him stand out is that he's both an InBrace Platinum Provider and a USC orthodontics professor, so he's incredibly current and knowledgeable. You can tell he genuinely loves what he does--he's meticulous and a total perfectionist in the best way possible. The office is super clean, modern, and high-tech, and the front desk team is always kind, responsive, and easy to reach (they even text, which I love). Scheduling has never been an issue. The InBrace process took longer than I initially expected, but after the first few months I barely noticed the braces--and honestly, I could've kept them on forever. They even helped me manage my eating habits, which was a huge plus, lol! And considering the results, I didn't mind the timeline at all. I could tell Dr. Youssef was investing extra time (without rushing or cutting corners) to make sure everything turned out perfectly. Occasionally the office wait times can be a bit longer, but it's simply because they never rush your care, and you can tell the doctor invests real time into getting everything perfect. Totally worth it. Another huge plus--they're connected to the dental office next door, which made coordinating my dental and ortho work super convenient. Ended up loving that office too! If you're thinking about braces or interested in InBrace, I can't recommend Dr. Youssef and the FitSmiles team enough. Best orthodontic experience I've ever had.

    First off, I have to explain that I'm not a dentist person. I'm usually all anxious and only go…read moreregularly because I know it's important...so the decision to willingly get orthodontic treatment was a big step for me. Also being an adult and getting braces, I was concerned it would make me look like a kid and impair my ability to talk. I went to a couple of orthodontist offices and got a lot of different feedback of what could and couldn't be done and what methods would be viable for me. Scheduling my free consultation was easy, and when I arrived I only waited a few minutes before I was taken back for photos and xrays. I have to applaud them for having some of the top equipment at this office. I wasn't forced to hold weird square of plastic in my mouth, or goop for impressions. It was all very comfortable, and the techs were super nice. I really enjoyed the thorough explanation that Dr. Park gave me about the plan for my teeth. She set realistic expectations and asked me about what was important to me about my smile. Even the payment options were a breeze to work through with the office manager. He didn't mind me and my husband asking lots of questions and reviewing the contract, and even said he was happy to explain anything. Also, they were the best pricing and payment options we found in the area! I'm three months into my 30 month braces plan and already see so much progress! I'm so happy I found this office.

    Initially I would of given a 5star review because the office is clean and the staff is for the most…read morepart very friendly. However my review is based on honesty and unfortunately that's not something I've experienced with this office. During my daughter's initial consultation for braces we were told she would need stage 1 at $3,400. ,being on a tight budget I went to 2 other orthodontist in the area to have an evaluation and receive their quote. The other orthodontist were charging me just a little more at $4,300, however they were stating my daughter also needed phase 2 and 3 but those were included in price. But since orthodontist Centre never mentioned phase 2 or 3 with me at our consult I felt like maybe I was being taking advantage of by the other offices and decided to go with my "cheaper option". We are now 14 months in and they have advise me that we are ready for phase 2 and 3...requiring an ADDITIONAL deposit and payment aside from the 3400.00I have already been paying. I'm very disappointed I feel like I was lied to, this should have all been discussed at the initial appointment. My oldest is also in need of orthodontic treatment, however we will go somewhere else to avoid tho situation.We live and learn. Unfortunately I was not familiar with orthodontic treatment in general I should have listened to the other offices and paid a little more and had everything taken care of. My advice would be to ask questions, cheaper is not always better especially here with the hidden cost.

To replace my retainers, I was first told I had to come in for a new scan because my previous scan could not be used. I go in only for the office staff to end up using my previous scan, which made that visit feel like a waste of time. After that, I was scheduled to come back the following Monday to pick up my retainers, but my appointment was rescheduled because I was told "I needed to be seen by the doctor." After adjusting my schedule, I came in only to not be seen by the doctor at all... meaning I could've kept my original appointment. The issue is the inconsistent information and poor communication throughout the process.

When I went back to my original orthodontist to ask about fixing it, I was shocked that they quoted me a fee that wasn't much lower than what I paid for my full treatment, even though only a few teeth had moved compared to where I started. It felt completely disproportionate to the problem. I did a lot of research and came across Life Orthodontics in Tustin, which offers touch-up aligners made in their office for cases exactly like mine. The price was genuinely reasonable, a fraction of what I'd been quoted elsewhere while still being treated by an orthodontist. What really sealed it for me was the Smile for Life Guarantee. Knowing that if my teeth ever shift again that I can get retreated for an even lower amount gave me real peace of mind. Hopefully I'll wear my retainers this time, but it's reassuring to know I'm covered either way. My experience with Dr. Robert Lee was excellent. What really impressed me was learning that he teaches clear aligner treatment to orthodontic residents at UCSF, so I knew I was in exceptionally capable hands for something I was nervous about. The office itself was also a pleasant surprise. It doesn't feel like a dental office at all. It's calm, beautifully designed, and his staff made the whole experience easy from start to finish. If you've had orthodontic relapse and your original office is quoting you a full retreatment fee, I'd strongly encourage you to look into Life Orthodontics first. I wish I'd found them for my first round of Invisalign!
