I have been a patient of Dr. Tai for 2 years so this review is long overdue. Before deciding on my treatment, I had 4 or 5 different consultations with different orthodontists, and I was about to give up and not going on with braces. At multiple consultations, I either felt rushed because the doctor did not want to spend their time discussing treatments or they suggested 4 years for my brace with teeth extraction. Dr. Tai was my last hope and he did not disappoint! Only Dr. Tai was willing to spend more than an hour to sit down and showed me my Xray, explained why he decided to do this, and went above and beyond to avoid having teeth extraction. You can tell that he really cares for his patients. The office is so clean and pretty, I thought the treatment cost would be expensive, but it was one of the most affordable quote I got. My brace treatment is quick and yields good results. I already referred 4,5 of my friends to him. Only down side is Dr. Tai is super busy, but that is a given if you want good Ivy League doctor

I recently moved to Irvine from China to attend school here. I saw one of my girl friend just had her braces removed, and she has beautiful straight white teeth. I been always wanting straighter teeth and a better smile, I figure now is the best time to get started. She told me to call Tai Ortho. Making the consult appointment was easy. Office is modern and new. I was greeted by Kaylie and Vicky, they were so friendly and sweet, then, I saw Dr.Tai and Dr.Chen. I love how both of them were very honest and detail with explaining my treatment options and what I will be expecting if I start treatment. I like how they both of them were able to speak Chinese. I felt very comfortable with the office, and most importantly I felt that they genuinely care for me. Their fees were surprisingly reasonable too compared to China and my other consults here. I am few months into treatment now, I can already see my smile improving. I can’t be happier with my experience here, and I highly recommend this office to anybody looking to get their teeth straighten

I absolutely recommend Dr. Tai Orthodontics to anyone and everyone! Whether it is your first time needing braces or you need to revisit previous treatments from other offices, Dr Mario Tai is the BEST! I came to Dr. Tai based on a recommendation from a coworker of mine ( who has braces and was very happy with Dr. Tai). I already have been through two rounds of metal braces with two other doctors (one when I was a teen -no complaints) and the other recently that was a nightmare. Dr. Tai is a master, he takes great pride in his work. Dr. Tai is incredibly intelligent and personable, he is very realistic in what treatment will look like for you as a patient. For me I feel he absolutely over delivered keeping the expectations with me very realistic. I appreciate his honesty and his level of artistic perfectionism to create the smile I desire. Dr. Tai is committed to making me happy and providing me with a result I am pleased with, I cannot thank him enough for the end result! I am so relieved I chose to move forward with Dr. Tai, I could’t be happier (and I am a perfectionist) 🙂 Dr. Tai and his entire staff are extremely polite, professional and understanding. It was very easy for me to book my first consultation appointment and every appointment following (added bonus, they are open on Saturdays!). It is refreshing to be greeted with positivity, feeling welcomed and be surrounded with staff that is knowledgeable, I feel very confident at Dr. Tai’s office. Office atmosphere is always clean and inviting. Appointments always run on time, I never have to wait more than a few minutes in the lobby.  Office is easy to get to and parking is ample. Communication in regards to appointments and care of braces is clear and polite. Paperwork with insurance and payment is clear and pleasant, fair and reasonable pricing. Sincerest thanks to Dr. Tai his entire staff for making the entire process for me so easy and pleasant. I love my new smile!

This is my first review.  I felt it was worth the time to sign up on Yelp and share my family and my experience at Dr. Mario Tai’s Orthodontics with the families that are truly in need of a great orthodontist. I highly recommend Dr. Tai for your orthodontic needs and the staffs are wonderful too! Our friends highly recommended him when our son needed braces.  My husband and I brought our kids in for free consultation.  Dr. Tai was very honest and professional.  He was the second orthodontist we had seen for our son.  The first orthodontist was expensive and had the high tech office.  However, Dr. Tai is very reasonable with also his high tech and innovative machines.  Our  son ended up getting braces at Dr. Tai’s Orthodontics, but our daughter had to wait.  Thereafter, our daughter had gone in for 3 more free consultation.  Finally, she was ready to begin her treatment.  We persisted on having Dr. Tai treat our daughter, because we felt he was very knowledgeable with his treatment plan for each of our  kids and thoroughly explained what needed to be done and the reason why he takes the certain approach When my dentist told me that I needed to change my bite due to repeated crack on the same tooth, I also went with Dr. Tai.  It was not just for the convenience since our kids were treated there, but I knew I would be in great hands. It won’t hurt to get Dr. Tai’s opinion on your orthodontic needs.  Call for a free consultation.  You won’t regret it!

All 3 of my girls have gone to Dr. Tai for braces and now all have completed their work and have beautiful, straight teeth. Dr. Tai is so friendly and so knowledgable. We love the staff as well and their office is beautiful and conveniently located. We were able to make appointments that worked for each child whenever we needed to and rarely did any of them have to wait too long. They were so helpful in accommodating us when more than one child had a visit around the same time, and with 3 that happened quite often.The office runs smoothly and efficiently and is always a pleasure to visit. We would highly recommend Dr. Tai for his professionalism, friendliness, thoroughness, reasonable pricing, and awesome staff and office

I did my teeth aligning with Dr. Tai for about two and half year, including two 3-months summer breaks that I was out of town and went back to China for visiting my families. It was an wonderful experience for me. The result was definitely beyond expectation and all of my families are happy that I can have a perfect teeth now. Dr. Tai is really thoughtful and attentive, and every staff in the office are welcoming and patient. It was such a enjoy every several weeks I went there for appointment. The adjustment for appointment is flexible and simple as well. I recommend to all of my friends who want to do the teeth aligning!

Dr. Tai was referred to me by my orthodontist from LA as my underwire retainer broke. He not only saw me the same day but did an amazing job fixing it. Dr. Tai and staff even allowed my kids to be in room with me during procedure.!!  The attention to customer service and experience was exceptional and will be referring to friends and family! Tina at the front desk is super friendly and got me in on a weekend! She rocks! Best Orthodontist in OC!! Come and see him!! He’s so down to earth and super patient

Before having Dr. Tai as my orthodontist, my mom and I have visited over 10 different orthodontists. Many of them were not up to the challenge and even if they were, they said that the only solution to solve my case is to have surgery in my jawbone. I had a severe overbite/ severe class 2. When we made an appointment with Dr. Tai, he was and still is very patient with us and he was up for the challenge. When he proposed an idea, we always try to find a non harmful yet an effective method to make my teeth normal again. Been having Dr. Tai as my orthodontist for over 5 years and I am very pleased with the results. Although the process took a long time, but the result is worth to wait for :). Highly recommend Dr. Tai because he is professional, experienced, patient, and kind. Thank you Dr. Tai for working hard on my teeth. I appreciate that. 🙂

Once upon a time I wore braces because my teeth were zigzagging all through jr high. I hated them but they did straighten out my smile. Unfortunately, I didn’t wear retainers after that and slowly but surely my teeth went back to being crooked. Now in my 30s, I really didn’t like the idea of wearing braces again so I decided to try invisiline as I had heard great things about it. I was referred to Dr Tai from my girlfriend who had gone to him for the same thing and she has a great smile (points for me). Dr. Tai was nothing but wonderful. After some scans and new computer 3D imaging techniques, I received my first treys to wear. It was super easy! Other than having to brush between meals all the time, they were hardly noticeable and Dr Tai always made sure I was coming along correctly and wearing them long enough. His office in Irvine is really nice and for anyone looking for an orthodontist I would highly recommend him. High fives!

Before the treatment, I was in my early 30s, I still had a baby teeth stuck and loose, a few permanent teeth did not came up straight and the teeth were crowded… since I came to US it was strongly recommended that I consider brace. Fortunately I found Dr. Tai on Yelp. Over the past months, Dr. Tai and the team was very skillful, professional, patient and creative on the treatment; they really strived for perfection and paid attention to every detail. Little by little, the bite finally aligns well and the result is beyond expectation. I really hope Yelp has an option of 6 stars!

I am a very careful mom when choosing a doctor for my kids. I have consulted several dentists before deciding on Dr. Mario Tai for my daughter’s orthodontic treatment.   Dr. Tai is a very caring, tentative and honest dentist. Now my daughter’s treatment is finished, the result comes out super great with a beautiful smile. Dr. Tai and his staff are so nice and professional. They tried their best to accommodate the time I preferred and always call me to remind me the next appointment. My daughter loves to go to Dr. Tai’s office and the whole treatment is pleasant and detailed. Dr. Tai always answers questions with a very detailed explanation. I found the best orthodontist for my daughter, I highly recommend Dr. Tai for your kids orthodontic treatment

Dr. Tai is absolutely wonderful. He is extremely caring, honest, and talented. He helped fix my bite several years ago, and went above and beyond his initial promises. For the first time in my life that I could remember, I could bite down on both sides of my jaw. My dentist was also extremely impressed by his work.The pricing for treatment (invisalign+braces) was affordable – he offered a special for UCI students. I fully recommend Dr. Tai!

Joanna S. from Irvine, CA (Source: Yelp)

★★★★★

I whole-heartedly recommend this Orthodontic practice. If you’re looking for a wonderful orthodontist I promise you, your search is over. From the friendly, knowledgeable, and welcoming staff, to the ultra modern and beautifully designed high tech office, this place is top notch! They go out of their way to accommodate you and Vicky you are just the best! Dr. Tai and Dr. Chen gently encourage my son, (he is super finicky and wanted his braces removed two days after they were placed). They took time out of their busy schedule to sit and re-explain the process to my son and helped give him the extra courage he needed to power through the first few days. It’s two weeks later and my son doesn’t even know his braces are on! I can’t thank Dr. Tai and Dr. Chen enough for all the kind guidance with myself and my son. I promise, you will be completely delighted with this dental practice! And his prices are super reasonable

Another update for the guy who fixed my occlusion! I was on a short visit back to Cali and I came back to visit Dr. Tai three years post-treatment!! Awesome orthodontist! He wanted to do a quick check-up, so he asked me to bite down.. open.. bite down again and he said “well done, Alvin!” Thanks for the quick p/t check-up! I don’t think I would ever need another treatment! Thanks to his meticulous and strategic treatment plan! Once again, I am forever indebted to you for my amazing smiles!

Giovanni D. from Costa Mesa, CA (Source: Yelp)

★★★★★

My teeth came out great, I came in with my teeth really crooked and Dr. Mario Tai helped me out and straighten my teeth. I had been recommended by my sister and I’m glad she did because Dr. Tai has been nothing but supportive and helpful in my goal to have straight teeth. Before I came in I couldn’t speak properly, nor could I eat properly and the appearance of my teeth always made me self conscious. After my braces treatment was over and I switched to my retainers, my smile was amazing and my confidence went above my expectations and I can confidently say I smile without any doubt in my mind that my teeth are beautiful all thanks to Dr. Tai and his great staff! Yes his staff is just as awesome as he is!

Joshua D. from Irvine, CA (Source: Yelp)

Dr. Tai has been my orthodontist since I began Invisalign treatment a few years ago.  I had consulted with several other doctors before finding Dr. Tai, yet he seemed the most knowledgable and understanding about my situation (mid 20’s, student, wanting to close large gaps in my bite).  He and his staff are very friendly and will treat you with great care and determination.  Everyone in the office is personable, helpful, and clearly enjoy working there.  About a year ago we discovered my top molars were stubbornly not rotating with the rest of my teeth.  Dr. Tai was quick to act and we decided the best route was to temporarily use wire braces for the top.  This is allowing more fine-tuned movement that Invisalign couldn’t help with.  Once the molars are properly aligned I can simply slip right back into the Invisalign.  This is not a very common situation but Dr. Tai is creative and really knows his shit 🙂 Very happy with the progress my teeth have made!

Dr Tai is the best Ortho, no exaggeration. He’s a perfectionist and an expert. I am almost done with my overbite, and all my kids are getting treatment here too. I have been telling all my friends who need a great ortho to go see Dr Tai first. Newly remodeled modern office with extremely accommodating staff too. Kaylie the assistant is super sweet and she even squeezed my daughter in for a last-minute appointment on a very busy day. That’s totally beyond my expectation. I’m so grateful to have found Dr Tai and his team. Highly recommended!

HIGHLY Recommend! My experience with Invisalign has so far been amazing! I am currently at week 12 of my treatment which means “tray 6” . Even though I am only on the six tray , I have seen quite a difference in my smile! Thanks to Dr. Tai and Dr. Chen! before I started my treatment with them, I consulted with many other orthodontists. I am so glad that I pick them. they are very professional , and patient . Dr. Tai and Chen took their time to answer all my questions. Their staffs are amazing. Their price is very reasonable. They are THE BEST. I am so pleased with my results . I highly recommend this place

Dr. Tai is absolutely amazing!! I had really crooked teeth as you can see from my before picture, and I shopped around for multiple orthodontists and many of them said I had to have teeth extracted in order to do braces, and that invisialign isn’t even an option for me. Then I came across Dr. Tai who reassured me that I can do invisialign without extracting any tooth. The price seemed extremely reasonable and fair as well. Throughout the process Dr. Tai really goes above and beyond to do check ups and make sure my progress is on track. He was able to have me finish the invisialign process within less than 1.5 years when other doctors told me I had to do atleast 2 years. I am more than pleased with the results and very very thankful that Dr. Tai has made this a very easy and stress free process, not to say he is so friendly and willing to answer all my questions as well. Also, I have to say he has the best staff members as well. Everyone is really nice in the office and makes you feel welcomed and comfortable in every visit. I am so happy with my smile today and would highly recommend anyone, child or adult to have Dr. Tai has your orthodontist!

I want to write this to remind people not to miss the best orthodontist. I started my braces two years ago. My dentist referred me to Dr. Tai. Dr. Tai is a professional, knowledgeable and responsible orthodontist. He can always provide perfect individualized service for you. I had two canine teeth, which makes the adjacent teeth deformity (small and short). Dr Tai gave me the best plan in my first consultation. Now, I can smile with more confidence with lined and healthy teeth. His staffs are very helpful and friendly. You will always feel welcomed and pleasant with them.  The office is very clean and tidy. The price is quite reasonable compare to other places. Besides his excellent techniques, Dr. Tai himself is also an easygoing, patient, trustworthy, and wise person. He is very thoughtful and cares a lot for the patients. He is not only an orthodontist, but also a best friend to his patients. I am a graduate student, we can always talk about the school life (Btw, he graduated from Harvard!!). I appreciate a lot for his positive encouragement and words.  All in all, I would highly recommend this awesome orthodontist

I was referred to Dr Tai by a friend and I couldn’t be more happy with the result.  You know when your insurance doesn’t cover orthodontic works and you will not settle for any orthodontist unless you know for sure he will give you a good smile.  I have to say I got my money worth. Dr Tai is very attentive and nice, and he has been patient with me since Day 1.  He will explain with details to every questions you have. I remembered the first day of consultation, he laid everything out to me.  I told him I wanted invisalign instead of braces, but of course braces adjust alot of faster than invisalign.  His price is very reasonable compare to other places I’ve done my research on.  He was very accommodating and gave me a payment plan since my insurance doesn’t cover orthodontic work (but the insurance covers my kids-if I have kids….which is stupid because I am the one paying for dental insurance).  Dr Tai explained to me the process based on how my teeth were.  For the first few months, I had to put braces on to adjust my overbite.  Painful but it’s worth it.  After a few months successfully adjusting my bite, I was stuck with the invisalign.  I had a total of 62 invisalign trays (10 days for each trays).  Do the math (it took forever) but it went by really quick.  The pros to having invisalign are the trays are clear (you can’t even tell I have a tray on my teeth) & you developed very good dental hygiene (you intake less sugar & you cut down junk food) because you don’t want to go brush your teeth every hour.  But keep in mind, you will need to develop really good habit of brushing and wearing the invisalign trays throughout the whole day for a better result.  if you don’t, you can’t blame the doctor for bad result.  If you’re a lazy person, then I wouldn’t suggest invisalign, go with the braces. Since I finished my last invisalign tray back in July 2015, there were minor adjustments that invisalign couldn’t fix (because of a huge gap that I had long time ago).  Dr Tai proposed to put braces on for about 3-4 months and that should fix the minor stuff.   So I moved up to Northern Cal about a year ago, and since I had the braces, I had to fly back every month to get the braces adjusted. which I didn’t mind because I trust Dr Tai that he will fix everything and I didn’t want to go to another orthodontist up in NorCal.  I am so happy that Dr Tai accommodate my appointments when I get a chance to fly back to LA.  Dr Tai and his staff were able to accommodate saturday appointments and it made my life so much easier and less stressful. His office is very nice, clean, modern, and comfortable.  The lobby is equipped with k-cups coffee, tea, and water.  The only bad thing I encountered is my cell phone reception is kinda weak.  I have verizon, not sure about other provider though.  Parking is not an issue here (at least on the wknd), there is a huge lot for this medical center. Overall, I highly recommend Dr Mario Tai, he is a honest and trustworthy doctor that doesn’t rip you off or make you feel uncomfortable.  I love it when Dr Tai gets super duper excited that my teeth are shifting beautifully.  and he figures out all these different ways to adjust my teeth, it’s like his new innovation.  He can do whatever he wants as long as it works for a better result and IT DOES WORK!!! Thank you Dr Tai for fixing my teeth. I am one satisfied patient

I loved this office, I can’t be happier cause I got my braces off today, and my teeth is nice straight and beautiful again ! This is my second time around, and the experience was much better than my first time. I am so glad I found Dr.Tai and Dr.Chen. They really made it simple and easy for me. I would definitely recommend it to my family and friends. Did I mention the amazing friendly staff?? Omg ! their new office is sooo nice

FRIENDLY, THOROUGH, EFFECTIVE!!! I searched thoroughly for an orthodontist to treat my daughter with braces. I settled on Dr. Tai for several reasons: Staff: His staff is EXTREMELY friendly and helpful. His office manager was very thorough on what our insurance would cover and they had a couple of options that were very suitable for our liking. Grade A++ Office: The office is very clean, the waiting room can become busy, but I would prefer a busy office than an empty one (a sign of how well the business is doing). They have: plenty of seating (I have seen it get full, but never over-booked), a large-screen television playing movies for the kiddies; a coffee maker and water for guests. A+ Patients: Everyone is smiling. Even the children!…in a dental office!…where pain is usually served on tap. And yet, Zee cheeldren: Zay smile! Adults alike. Doctor: Dr. Tai’s staff is a reflection of him in regards to friendliness and caring. He took his time on our first visit and does so every time we see him, to address all of our concerns and answer all of our questions. True story: During our consultation, I shared with him a differing approach to treatment that another orthodontist had (who I was considering). Instead of bashing his fellow orthodontist, he stated his reasons based on his experience. And he was humble enough to say, “maybe the other orthodontist has had different results that I have had using ‘that’ method…I would call him and ask him these questions…” And they were honest questions, not constructed to “stump” the doctor, but rather to assist me in making the decision that was best for us. I found his humility, honesty and kindness (again) very refreshing. Grade A++ UPDATE: My daughter has been a patient of his for over seven months now and every time, his administrative staff and his dental assistants have been the most pleasant people to deal with. They remember my daughter by name and I feel that they have established a relationship with her. It is a “happy office” and we look forward to each visit. Technically, my daughter’s treatments are coming along very nicely! We are all so pleased with the progress of her teeth straightening. Dr. Tai and staff have my highest recommendation!

I first chose to go with Dr. Tai for my Invisalign back in 2014. I went to a lot of orthodontists for consultations and he was the clear choice among them. He was very up front about what I could or couldn’t accomplish with Invisalign and it was clear he had the experience both professionally and academically to back that up. Best of all his price was incredibly reasonable compared to the other places I checked out! It was a no brainer. Fast forward a couple years and my treatment was all done and my teeth looked great! Exactly what I was hoping for. Dr. Tai and his staff were very accommodating throughout the whole process. He’s consistently evaluating how your teeth are doing as you progress and if there needs to be any adjustments made he doesn’t hesitate to put in the extra work. The proof is in the results and I couldn’t be happier with how everything turned out. If you’re considering going with Invisalign I wouldn’t hesitate to arrange a consultation with Dr. Tai

Charlotte S. from Garden Grove, CA (Source: Yelp)

I guess I experienced something different then everyone else. I went to this place trying to get my clear aligners, and after I paid, they told me that they would contact me once Dr. Tai had the treatment plan ready whether it is with extraction or not. However, i waited for half a month, and no one contacted me, so I called them. They told me they would try to find out what’s going on with my case, and call me back later. They never called me back. Now it has been over a month, I have called five times. They kept telling me the same thing that they will call me back, but they never did. I think I am gonna wait for one more day. Except this, everything else is good. Dr. Tai is professional and caring, and the office is nice and clean. But the customer service is way below than what I expected. Hopefully they will call me back today. Problem solved

Viv A. from Placentia, CA (Source: Yelp)

Thanks to Dr. Tai I now have the confidence to smile. I got Invisalign and he’s not like other dentist that think that by taking impressions, Invisalign will take care of the rest, Dr. Tai monitors your teeth are moving the way they are supposed to and make any changes he considers necessary. I am so thankful to him and his honest desire to make you happy. I’ve recommended friends and family to him

Niree K. from Los Angeles, CA (Source: Yelp)

Dr. Tai and his staff are wonderful! I consulted with a few orthodontists before deciding to start treatment with Dr. Tai. He offers his own line of clear aligners, which are more efficient (he has full control over the alignment plan; he can print new aligners in a day) and cost-effective compared to national competitors. Dr. Tai and his staff are always welcoming, friendly, and professional

Today marks my last official Invisalign appointment with Dr. Tai, my orthodontist. Ever since high school, I’d always had a complex regarding the gaps in between the teeth, and the dentist would always recommend stuffs like metal braces, removing wisdom teeth, and even jaw surgery. However, Dr. Tai was different, and I was able to complete 1 year of Invisalign treatment with my whole jaw and teeth still intact. I am satisfied with the result, and here are just a few facts based on personal experience: Pros: no food restriction (but i found it hard to chew stuffs like boba since my teeth was weak and aching with new trays), easy to clean, brief office visits, weight loss?! (LOL i thought i would lose weight but it didn’t really happen… maybe 5 lbs) Cons: you will get dry, chapped lips, possible canker sore, and annoying toothache that can last up to a week with each tray change, teeth become sensitive after removal of attachments, tray cleaning is kinda tedious though Dr. Tai is really nice, and he would try his best to take care of your teeth

Our dentist referred my son to Dr. Tai in 2013 and he is currently receiving treatment.  I also started seeing Dr. Tai due to my fixed retainers. I’ve had braces twice (first as a teenager and later as an adult- both times lasting between 2-4 years).  My dental cleaning last week pulled the wire out slightly, which caused a space to open between my upper front teeth and the wire broke yesterday.  I called Dr. Tai’s office and got an appointment for early this morning.  Dr. Tai was busy but he took the time to examine the problem, removed the old wire and glue and created a new fixed retainer- all the while concerned about my time schedule.  Wow!! If you’re looking for a knowledgeable, very competent, caring and patient orthodontist-  Dr. Tai is your man!!  Dr. Tai and his staff are absolutely wonderful!

My friend introduced Dr. Tai to me. He was very careful, professional, and spent a quite time with me to check everything for me and reviewed all the x-Ray images in details for my first two visits. I got a strong confidence and believed he will do the best job for me. I went with him in the past two years, every time I visited, he checked very carefully and is very technical and detail oriented. He works so hard, and his schedule is soflexible, so I could even go to his office on Saturday, it made much easy for our working people as well. After removing my braces, my tooth is perfect and my smile is so great, I love my smiling very much. Dr. Tai and his staff did excellent job for me. I highly recommended him to you

Dr. Tai is an amazing orthodontist, and I had a wonderful experience with him! I had an under bite when I was younger, but he did a great job at correcting my under bite and straightening my teeth. He is always so helpful and whenever my braces were bothering me or cutting into my mouth, he would always cut any wire sticking out, while my friends with other orthodontists were told to cut it themselves with a nail clipper. Dr. Tai is very understanding, and I am so happy I chose him as my orthodontist!

I have been under Dr. Tai’s orthodontic care for sometime now and he is above and beyond in results, service, and care. Going to his office is like going to my extended family. I feel his patients feel the same because it is always smiles there with or without braces. Now with his new office, I look forward to going there to catch up with his great staff and Dr. Tai

I am so happy that I found Dr. Tai’s office for my orthodontic treatment. I’m a general dentist it’s hard for me to easily trust anyone with my teeth but I found Dr. Tai as the orthodontist whom I can trust. He helped improve my smile through his thoroughness and expertise. I went in for a consultation but from the second I walked into Dr. Tai’s office to the completion of my treatment I cannot emphasize enough how professional, kind, and thorough he has been with my treatment. He made sure to spend enough time with me during the Consultation to understand what my expectations were and based on that he provided me a very thorough step by step treatment plan. He has gained my trust and I will highly recommend him for anyone interested in orthodontic treatment. Thank you Dr. Tai
