I saw Dr. Abai again a couple months ago, this time for an implant in an upper molar that had previously had a failed root canal. Unfortunately there was no saving the tooth, fortunately i had Dr. Abai to perform the implant. I was expecting the worst - had heard that implants are painful and a hassle - but he made it so easy. The years of experience and excellent training really helped here - the old tooth was out before i even knew what was going on and the prep for the implant was done quickly and smoothly (Dr A knows exactly how to numb you so you won't feel a thing!) segway forward couple months when the post and the crown were in - minimal hassle, perfect fit, and excellent function. If you need any dental work especially implants, do yourself a favor and go see Dr Abai, you'll be glad you did! read more

I hope my experience helps someone who feels as lost as I did. After a full mouth restoration with another dentist went horribly wrong, I was living in constant pain. I couldn't sleep, chew, or eat without fear, and I truly believed no one could fix the damage. Then I found Dr. Abai. From the first appointment, he listened, understood what had gone wrong, and approached my case with so much care and precision. For the first time in months, I felt hope. His is amazing. He corrected what had been missed, rebuilt my bite, and brought me relief I didn't think was possible. Today, I can eat, smile, and live without pain or fear. His office is spotless and beautifully organized, and his entire team -- from the front desk to his assistants -- is kind, professional, and genuinely caring. He didn't just fix my teeth -- he gave me back a part of myself I thought was gone. If you're in pain or unsure where to turn, please go to him first. read more

Just got 2 All-Ceramic Implants and not once did I wince in pain and I feel Great! Dr Sia Abai did an amazing job to make the process easy and painless and the aesthetic results are so natural and perfect! I highly recommend Dr. Sia Abai for all Dental Implants and cosmetic dentistry procedures! My teeth have never looked better, and I'm grateful for his expertise. read more

Dr. Abai has credentials galore. But what makes him a standout is he guided me with recommendations on LOTS of options, from least invasive to most (ortho, biomimetics, crowns) even though some of the options were not in his wheelhouse / specialty. (He specializes in dental implants and reconstructive dentistry - Extractions, bone grafts, all on 4 dental implants, esthetic reconstruction.) He even recommended what he would do if it were his teeth (ortho or biomimetics) and gave me two great referrals. This is the mark of a professional putting your interests first. And he is kind and personable too. I recommend him. Thank you, Dr. Abai for your time and guidance. I will come back to you for other needs. read more

I can't say enough good things about Dr. Abai.From the very first consultation, I felt completely at ease. Doctor took the time to explain the entire implant process step by step, answered all of my questions, and never made me feel rushed. The procedure itself was smoother than I imagined. Doctor made sure I was comfortable the whole time, and the follow-up care has been excellent. Now that I'm healed, I couldn't be happier with the results. My implant looks and feels completely natural, and I finally have my confidence back when I smile. If you're considering dental implants, I highly recommend Dr. Abai he is Professional, compassionate, and incredibly skilled--you'll be in the best hands. read more

As a dentist myself, I can be very selective about who I go to for my own dental needs. Believe it or not, even dentists can have anxiety about finding a fellow doctor who is competent, ethical, and friendly. That being said, I'm relieved to have ended up with Dr. Abai. My experience with him was excellent. He was as skillful and knowledgable as you would expect of a dentist trained at Columbia and Harvard Universities with a couple decades worth of experience; but maybe most importantly, he was equally as down-to-earth, honest, and likable. His office was clean and comfortable, his staff was professional and courteous, and parking was easy. I would highly recommended Dr. Abai to anyone who might need him. read more

I must agree with the other Yelpers when they say that Dr. Sia puts his patients 1st. I had an unusual situation and was in excruciating pain today...Sunday. Dr. Sia had a family event that he cut short just to see me today. How many other Dentists care that much about their patients? I have an EXTREME phobia about going to a dentist after having my lip drilled by a former dentist over 15 years ago. I shared my anxiety with Dr. Sia and he was ever respectful of my fears. This was the BEST experience I've ever had with a Dentist and am ever so grateful that I was fortunate enough to have met him. For any of you Yelpers that are seeking a dentist or those of you that share with me and the anxiety you feel just scheduling a dental appointment...look no further and put your trust and dental care with Dr Sia. read more

You have to be very careful when choosing a dentist. I know. My father was a dentist. My dad was not only a dentist, he was a famous dentist. After he retired from his illustrious career, he was chosen as the Director of Advanced Dentistry at Columbia University in NYC . When my wife and I both needed some significant dental work, I called my father for advice. Out of the hundreds of dentists that made it through his program, many had landed in SoCal. With total confidence my dad sent his son and daughter-in-law to Dr. Sia Abai. According to my dad, Sia was one of the finest dentists to ever graduate from his Ivy League advanced dentistry program. Dr Abai has proven to be fast, painless, caring, brilliant, and very likeable. He gave us several options and allowed us to make well informed choices on our care. Great , clean office. Easy parking. And Dr. Abai is as fine a dentist as you can find anywhere in the world. That's what I was told. And I found it to be the truth! read more

I've known Dr. Abai by over 10 years he used to be a client of mine, now I am a client of his! It's difficult to find somebody with such vast experience and knowledge in dentistry and on top of that Harvard trained wow, but he's just a regular person a kind souls so caring specializing in gentle dentistry. He truly loves his patients he focuses on quality not quantity. I am Real Estate Broker so I need to look my best. Recently had an issue with my FRONT tooth somehow I broke a root. What I love about him he made every effort to see if he could save it. If you're looking for honest, caring and high integrity then look no further! I put my reputation on the line on referring him! I cannot afford to refer someone who is not fully committed as I am in my business. Dr Abai I'm thankful we met so many years ago. From day one I knew you were a kind caring soul. I highly recommend Dr Abai to care for your families dental health ARTHUR CERVANTES, Broker/Realtor®/Private Lending Schultz Elite Financial Services *CalBRE#01984162  * 714-603-2945   * iarthurc@gmail.com Ask me about 100% Financing! read more

Sia Abai has good bedside manners. However, he is quite the quirky weirdo who will bend over backwards if he wants something, but will step back from something if its not his most satisfying item. His focus is not the best interest of the patient and what he can do to fulfill that. He's not that "keeper" or the person who really cares about YOU and your health in a genuine manner, besides this being a job. You may think he does from the way he presents himself in his office, but when time comes to make decisions, he'll step over you any day and avoid responding, and will have some bullshit excuse as to why he won't care for your health. read more

Dr Sia Abai is a very skilled and extremely knowledgeable dentist. I am a dentist myself and know quality work. When I found myself in need of dental work, I called Dr Abai. He is a perfectionist with excellent hand skills and a wonderful bed side manner. The procedure was quick and absolutely pain free. His work is perfection and I was so happy with the results. Dr Abai and his assistant made sure I was comfortable and I was even laughing throughout the procedure. His dental chair is so comfortable, i did not mind being there for the long procedure time. I also love his painting of corgis at the beach, it made me smile. I noticed he uses quality products and a top local lab. His office is beautiful and extremely clean with a nice view. I was also impressed by his credentials, Columbia University followed by a masters in prosthodontics at Harvard. Dr Abai is smart, gentle and does quality work. I'm very grateful I found Dr Abai and highly recommend him. read more

In all the years I've gone to the dentist I have never experienced anything like this visit. It was perfect, professional, and painless. Dr Abai's technique and experience was amazing. I did not feel any pain at all- (I got numbed and had a filling and crown done.) Extra bonus- it's one on one patient care so there is no waiting around. read more

Dr. Abai is the best dentist ever. I had a tumor of the mouth and needed several implants after the tumor. He did an amazing job throughout the entire process. He communicated with me thoroughly and I knew what to expect each step of the way. He offer concern, compassion and understanding of my unique situation. His follow through is timely and reliable. I have been to many dentist (unfortunately) in my lifetime but Dr. Abai rates as one of the best. I was so pleased I moved my son to his practice as well. As a UCI anteater, he is amongst the top in his profession. read more

Dr. Abai and his office are amazing. Sia (goes by his first name) CARES about his patients ....unlike any dentist and most doctors i've ever had. Feels like once you sit in his chair you've become part of the family. That's the way he wants it. Nicole is his assistant and has been with him 7 years; they're a great team...experts, calm, gentle caring.... i even fell asleep at one point (in a 2.5 hour procedure). and my teeth look and feel great after the work. And, here's a twist....Just for fun and to show how much he appreciated ME....he gifted me a Sonic Diamond Power Toothbrush!!! huge surprise. iI joked that i'd put it on Yelp and he said 'go ahead'...i love my patients...they all get one'! So hold him to it when you go...he'll laugh with you. really appreciate Sia, the team and the office...Hope you do too. Grace B p.s. he loves to 'teach' as he goes along, so if you're interested in dentistry and how it all works....he's game. so FUN! read more

Dr. Abai is definitely one of the friendliest dentists I've ever been to. From the beginning, I could tell he was very personable and I felt comfortable receiving dental care from him. I came in to get a nightguard since I've been grinding my teeth. When he was getting the impression of my teeth, he explained that many other dentists don't do it exactly how he does. His way made sure he had the most accurate impression possible. I like to know what's going on, especially when it has to do with medical/dental care, so I was really glad that he explained everything he was doing as he was doing it. When my nightguard was finally finished, he was very thorough in making adjustments to make sure it fit my teeth perfectly. Even through that process, he explained exactly what he was doing and helped me understand the adjustments he was making and why he was making them. Overall, I could see how much care and attention Dr. Abai puts into his work. He actually cares and wants the best for his patients. I know he works in multiple offices, but his office in Tustin is actually inside of a dental lab. I've never seen this before - when I asked him about it, he said it allows him to control the quality since he gets to work closely with the products and the people in the lab. I would definitely recommend anyone to come and visit Dr. Abai to get some of the best service and products possible. read more

Great work Dr Abai does. He put 8 implants in my mouth for overdentures. Very professional and knowledgeable. He made me feel so comfortable. I'm so glad that I made the right choice. I would highly recommend his work. Excellent read more

Limited abilities. Argumentative and unethical. Hostile, threatening, and uncaring. He feels no duty or obligations toward patients in need citing conflicting policies (non existence) with the norm and widely adopted protocols in the industry. Highly questionable practice. It took more two weeks to make an appointment were he trys to size you up without looking at your teeth. He flip flops numerous time and criss cross you with no end insight. No staff to make an appointment with and prolonged and broken response time adds to your frustration with this so called care provider. His shortcomings, however significant translates into innuendos of policies, being busy and not taking new patients. Nothing but hideouts. It would be no surprise to have other reviewers go out of their ways to write on minor work and seldom appearance. It is unfortunate that a care professional waists your time rather than attending to your needs and honor the professional oath he took. Compelled to share this with the CA board. read more

Dr. Abai was fantastic! He prepared and walked me through what to expect with my dental implant and I felt very secure and taken care of. He is a skilled oral surgeon with great people skills. I had been procrastinating to fix my tooth for way to long and he took my hand or my mouth I should say and went to work. The process is not easy as you can imagine but I was thoroughly impressed by his care. He was gentle, careful, and he made sure the job was done right! He even stayed late at the office with his staff on a Friday night to make sure I was taken care of. I hope I never need a dental implant again but if I do I highly recommend Dr. Abai! Thank you so much. read more

5 stars! Dr. Abai was great. I scheduled a consultation with him after my regular dentist tried a quick fix on me. My 2 front teeth both chipped & my regular dentist shaped the corners and was ready to cure 5 min later but shaped it oddly. I didn't let them cure it & opted out. That's when I went on a search for a dentist that would have my best interest. I found Dr. Sara Han online but she's in Nor Cal! I was ready to fly out but she said I'd be in even better hands with Dr. Abai here in OC, only 15 min from me. The consultation was thorough and comfortable. The office was very welcoming. I shared my dental work history and told him that I wanted to fix the chipped corners. He recommended to start conservative & try bonding. I was back a week later to get it done! He took his time and did bit by bit to ensure the best results possible. Taking a total of 1 hr & 30 min. I am so happy with my results! He did a perfect color match and perfect shaping so it was completely undetectable. Can't compare to the 5 min fix my reg dentist tried on me. Definitely recommending friends and family to come here. Thanks again Dr. Abai! read more

Dr. Abai is one of the BEST! I've been in the dental business since 1989 and know thousands of dentists throughout North America and I chose him to do my dental work. Extremely professional, perfectionist, great appointment times that fit my schedule and most importantly, AFFORDABLE. I highly recommend Dr. Abai to anyone who wants to maintain, or get a beautiful smile!! read more

Amazing experience. I had my uppers replaced with cubic implants and Sia also fixed implants that were done unprofessionally by another dentist. While we are still in the process of finishing the restoration, Sia has made my smile younger and more attractive than it actually was when I was younger. Sia is available, flexible, and always puts the needs of the patients first. Do yourself a favor and stay away from the "smile mills" read more

My appointment with Dr. Abai has been the best dentist experience I've ever had. Dr. Abai was kind enough to see me after I was concerned about all the services another dentist was trying to tell me I needed. He did my exam and told me what issues I actually needed to fix and did not try to sell me any merchandise or unnecessary services. He talked me through the entire process and helped curb my fear of being in a dental office. He also worked with my insurance to ensure he would be able to help me. I would recommend him to anyone who is looking for an honest and kind dentist. I'm happy to have found him! read more

If you need a good dentist, I would highly recommend Dr Abai, he's an excellent dentist and prosthodontist. He is very precise, neat and attentive to detail. Having been a dental assistant I have a background to attest to this. I had work done by him including a couple of implants and he did a stellar job and all the while having a gentle hand and a comforting bedside manner for those of us horrified of dentists this is high on our needs list. He has integrity and the well being of his patients always in mind. You won't be afraid of dentist appointments anymore. :) read more

i recently had a surgical procedure done by Dr. Abai. Im in the dental field and have worked with many practitioners so this review is both from a patient and a colleague's point of view. He did an amazing job in controlling my nerves and the clinical results were beautiful. did not expect anything less as i picked my provider with a very critical eye. thank you. read more

I came here for help with a previously-made temporary tooth and he beyond exceeded my expectations! Temporaries are difficult to match, but after spending an hour with me, he transformed the odd-looking temporary tooth into an amazing replacement with little discrepancies to my real teeth. After many frustrations with the temporary at my oral surgeon's office, this was such a relief and I am so happy with the result! Thank you so much. read more

No amount of praise is enough for Dr. Abai. He is a wonderful dentist that will make you feel comfortable and explain what's going on every step of the way. He is very thorough and took the time to answer every single question I had. I cannot recommend him enough. read more

Dr. Abai is a great dentist with a very pleasant demeanor. He's not just a dentist, he is a prosthodontist, which means he has advanced dental training. He is extremely knowledgeable and professional. He offers flexible appointment times, he even works on Saturday! He takes great care of my smile. If you are looking for a new dentist, you should make an appointment today. He's the best! read more

Dr. Abai and his staff are patient, friendly and professional. Dr. Abai takes pride in his work and is very thorough. The office space is welcoming and clean. read more

I'll start off by saying that I have never taken the time to write a review however after my experience at this office I wanted to. Due to my hectic schedule I have ignored going to the dentist for years. Let's be honest, even if I had time I probably would put it off since having dental work done is not exactly appealing. I have had a lot of dental work when I was younger and over the past couple years they started bothering me but I kept ignoring it. It started with pain on the left side so I used my right side to chew. Eventually the right side started hurting so I used whichever side hurt less on that particular day. I kept procrastinating till the pain was waking me up at night. I was now motivated to go in but I didn't have a dentist. My co-worker's wife is a dental assistant so I asked her who her dentist is and to my surprise it was not the dentist she worked for. I asked why and apparently the previous dentist she worked for used to go to Dr Abai so she started going to him too after her employer retired. I guess it makes sense, why go to your dentist when you can go to your dentist's dentist? I figured if others in that field trusted this guy then maybe he was worth a try. Dr Abai was great. There was a sense of calm about him which put me at ease right off the bat. After his exam he took the time to answer all my questions. He was very gentle when he worked on me too. To top it all off, the office was beautiful. It was modern, clean, and pretty good view too. His staff was friendly and professional also. All in all, I am pleased with my experience and will return here again. read more

My recent two visits with Dr. Abai have been nothing but stellar. Through a trusted referral, I went to Dr. Abai for the treatment of a chipped tooth and several fillings. First, the office is beautiful, pristine and comfortable. Karen at the reception desk is friendly as can be. There is even a view of the Pacific Ocean - definitely the best view I've seen at a dentist's office. While another dentist had recommended a crown for my chipped tooth, Dr Abai was able to rebuild my tooth so beautifully with a filling that it looks indistinguishable from the rest. He is such a meticulous worker and will make sure that you are comfortable all the while. I appreciated the good work, the friendly and caring demeanor and the fact that he saved me the expense of a crown! read more

I could not be more pleased with the level of professional service I enjoyed a while under the care of Dr. Abai. The staff was helpful and compassionate and Dr. Abai made certain my procedure was painless while delivering as result beyond my best expectations! I highly recommend Dr. Abai to anyone looking for the finest dental care and a million dollar smile! read more

Dr. Abai was one of the most professional, efficient, honest dentists I have experienced in Orange County. Highly recommended. Friendly office. read more

Dr. Abai is the nicest, kindest, most skilled dentist that I've ever met. I found out that after going to dental school at Columbia University, he went to Harvard and studied another 3 years to become an implant specialist -- a "prosthodontist". It is my understanding that out of about 200,000 dentists in the U.S., Dr. Abai is one of only about 3,500 dentists who has his level of training. I also found out that he has given numerous lectures at dental conferences. Very impressive. read more

An excellent facility! Very clean and friendly staff. Extremely knowledgable and committed to each patient. Highly recommended.

I was referred to Dr. Abai by a family friend and I could not be more happy with the work done so far! I had a lot of work I was very nervous/hesitant to get started on, but Sia made me feel super comfortable. He has made my visits convenient, affordable and painless as possible. If you are looking for an honest dentist who truly cares about his patients, this is the place for you! read more

Picking a dentist is a very personal experience and @ times can be scary, whether it was a tramatic experience you encountered at your OTHER dental office. Or you felt unfairly charged for dental work that was done. Whatever your experience was... I would say your search for a dentist is over. Or if you are in the process interviewing a dentist on you dental treatment, definitely worth the time to sit down and discuss your situation and case with Dr.Abai. I have been very fortunate to have worked with him and been involved with some large dental cases. Dr.Abai REALLY takes his time to discuss your treatment and will give you different options that would best fit your needs, sincerely cares for his patients and will make sure all your questions are answered. So when you leave his office, you will feel confident in making the best decision for you! As for Dr. Abai's work, well let's say he is a perfectionist. His bedside manner is very professional and empathetic. I hope this helps, Good Luck! read more

Dr. Abai is a great dentist. Making an appointment was a breeze. The office staff is very friendly, polite, and accommodating. I was having a total hip replacement for PVNS disease of the hip and needed to fix all my teeth before my procedure. I arrived at the offices in Newport Beach and relaxed a little bit in the waiting room before being asked back to the modern and private offices. The facility is first-class and has the latest technology and cutting edge equipment, laboratory, and surgery room! Dr. Abai and his assistant took X-rays and determined that I needed 9 cavities re-filled and one crown replaced. The set me up for 4 appointments and completed all of the repairs right on time as they promised. It was a very comfortable experience from start to finish. I didn't even feel the needle for the anesthetic shots and I wasn't numb for like 5 hours afterwards. He doesn't just shoot you up with an excessive amount of novocaine and he understands exactly where to give the shot so that it precisely numbs the right spot only. Dr. Abai and his assistant really explained everything clearly and they pay attention to all the details. I noticed that they don't settle for no less than perfection even if they have to exhaust themselves to achieve it! Other dentists I have visited have never had such focus or attention to the subtle but important details such as having a perfect bite and creating the appropriate fit so that food doesn't get trapped between the teeth. It's been 1 month since my fillings and my teeth feel great, no sensitivity, no food getting trapped, or no stains. I look forward to continuing to work with Dr. Abai to maintain my dental health and remain pain free and healthy. I highly recommend making an appointment with Dr. Abai and his dental team! read more
