Dolores C. from Costa Mesa, CA (Source: Yelp)


Dr. Bui and his staff offer superior dental care to their patients! I have been going to Dr. Bui for sixteen years and I wouldn’t consider going anywhere else! I have referred many of my coworkers and friends to him. My husband who had not visited a dentist since he was a child, agreed to go to Dr. Bui and he loves him!

My husband and I have been going to see Dr Bui and his lovely staff for about 15 years. Honestly the best experience I have ever had with a dentist. He is very professional yet down to earth and take to you not to his notes in a book. Lily as the first face you come into contact with is a ray of sunshine. She clearly explains all your options so you walk into everything very prepared. We highly recommend Dr Bui and his staff for all your dental needs.

Odhet H. from Upland, CA (Source: Yelp)


Dr. Bui’s was the best & always made me feel comfortable. I was scared my teeth would never look the same after my fall but they are beyond beautiful! Now that my procedure is over I am truly going to miss him and the girls! I will be back to whiten my teeth soon. I highly recommend him to anyone

Jeannie R. from Brea, CA (Source: Yelp)


Dr. Bui and his staff are the “very best”.  You will be greeted by Lilly with her beautiful smile.  Sweet Barbara will take your ex-rays.  And then Dr. Bui will work his magic.  Dr. Bui is a friendly and highly skilled professional who takes the time to make sure your are comfortable.  He is very thorough and detailed, clearly explaining any work that needs to be done.  It is obvious Dr Bui loves what he does.  He strives to make your experience a positive one.  If I could give Dr Bui and his staff 10 stars, I would.  Thank you for your excellent care

I needed a crown on a front tooth and decided to visit Dr. Bui based on his Yelp reviews. Let me tell you he did not disappoint. My crown turned out beautiful and I am so happy! The girl that works in the front was very nice and very accommodating with my difficult school schedule. I recommend Dr. Bui and his office now to all my family and friends. Thanks for giving me a beautiful smile!

I am so lucky to have found Dr. Bui and his wonderful assistant Lily!  They have been our family dentist for almost 15 years and I will not even consider going elsewhere. I have anxiety issues and totally freak out when it comes to dental work but this team really cares about the comfort of the patient. I have never had a dentist call me the day after a procedure to ask how I was doing. I have referred Dr. Bui to several others and they come back to thank me for such a great referral.  Dr. Bui spends time with his patients and explains what he will do and why it needs to be done. He also gives options so you can make an informed decision. Lily is great too! She has firsthand knowledge on what you will go through because of her background and is so friendly and easy to talk to. They are THE BEST!

Mike B. from Mission Viejo, CA (Source: Yelp)


I was sent to Dr. Bui’s office reference a workman’s comp claim.  Dr. Bui was very professional and understood my needs.  Dr. Bui explained everything to me prior to doing any work.  He provided me with headphones and sunglasses while performing work on my teeth, which had never been done before by other dentists.  Dr. Bui is an excellent dentist and great person.  He is very nice, pleasant, and a professional dentist.  I am so pleased with his work. I can not tell you enough how happy and pleased I am with his work.  Dr. Bui’s staff is awesome as well.  They are so caring and helpful.  I would have to agree with Kevin L..   Dr. Bui is the pinnacle of dentistry, his dental expertise is above and beyond my former dentist care.  My teeth have never felt better.  I have a new dentist from now on.  I highly recommend Dr. Bui as a dentist for you.  You will be pleased with his service

I was recently recommended to Dr Bui’s office by a friend. From the moment I walked in I felt extremely welcomed and comfortable. Lilly the the front desk lady was very nice and explained everything so I could easily know what to expect during my treatment. Dr Bui and his assistant Barbara were the absolute best! I highly recommend them for all your dental needs.

Johnny B. from Pomona, CA (Source: Yelp)


This is by far the best dental experience I’ve ever had. Very professional no wait same dentist very clean top shelf establishment. Dr Buiand his beautiful staff make for a great experience!!! Never thought I’d look forward to going to the dentist can’t say enough good things !!!

Brianna M. from Orange, CA (Source: Yelp)


I’ve been a patient of Dr. Bui’s for approximately 10 years. He has been nothing but amazing to me and my entire family. I use to be afraid of going to the dentist, but after my first visit with Dr. Bui, I overcame my fear. Not only do I love the dentist, but his staff is also extremely welcoming and the office is kept very clean and cozy. I’ve gotten a lot of cosmetic fillings done and I could not be happier. I recently had my teeth whitening done over Thanksgiving break, and I’ve gotten so many compliments. I love my smile now!

Terri G. from Yorba Linda, CA (Source: Yelp)


I love Dr. Bui. He is a very thorough and explains things every step of the way. He recently made a bridge for me and it is working out real good. In the past I also had to have a crown the temporary crown fell out (after having had it on for about 3 weeks)on a Friday at 4:45 PM. I called his office, they were closed. So I called his personal cell # which he leaves on his answering machine in case you have any problems. He said he would meet me at his office in 30 minutes. He apologized because he was at Home Depot and couldn’t come any sooner. 🙂 Now, what dentist would do that? Only one who cares for his patients. He takes his time in making sure everything looks and feels as it should. If you are not happy then he is not happy. I have recommended Dr. Bui to several of my co-workers, friends and family.  They all have thanked me for sending them to him. Give his office a call. You won’t be sorry

David T. from Tustin, CA (Source: Yelp)


I recently moved from Nor Cal and needed a new dentist. I came in from a recommendation from a friend of mine. I came in for a cleaning and for x rays. The staff was very friendly. Christina took my x rays and was very gentle with the positioning of the x rays and was very friendly. Then came the cleaning. Usually other dentists i have encountered would make the cleaning part hurt but not Dr Bui. It was very thorough and pretty painless. He always kept asking to make sure i wasn’t in pain. i also had to get my fillings refilled and he was able to do that quickly for me as well with very a very reasonable price. Can’t complain about a Dentist who takes care of his patient and their wallets. =) So glad my friend recommended him.

Jessica C. from San Diego, CA (Source: Yelp)


While I normally hate going to the dentist, Dr. Bui doesn’t make it so bad. He is so kind and lovely to talk to, even with dental tools in your mouth. He remembers me even after months of not seeing me, and He does a great job on my teeth! I feel so taken care of, and his office is beautiful too. Go see Dr. Bui!!!

Carl C. from Orange, CA (Source: Yelp)


Dr. Bui is an excellent and highly skilled dentist.  He is very thorough and detailed.  If any work needs to be done, he clearly explains all your options and his recommendation.  Perhaps most importantly though, he has a lot of integrity and is always looking out for what’s best for his patients. His staff is always friendly and helpful, and making appointments is always super convenient. I highly recommend Dr. Bui!

Ted T. from Orange, CA (Source: Yelp)


Dr Bui and his staff are amazing. Dr Bui takes time to explain everything, gives you pros/cons of your different options and his recommendation. I’ve been seeing Dr Bui for a few years now and he’s done my regular cleaning, deep cleaning, filled cavities and a crown. Everything was well explained and I never ever felt like I was being “sold” or talked into getting something done. That’s not how Dr Bui works. He’s thorough, honest and cares about his patients. Lily at the front desk is the best, super nice, accommodating and always willing to help. Barbara, the dental assistant, is also very friendly and sweet. If you’ve been putting off see a dentist, then give Dr Bui a shot. You won’t be disappointed.

I feel guilty for waiting this long to “yelp” Dr. James Bui. First off, Lilly (and her contagious beautiful smile) is absolutely one of the most pleasant,  professional women that I have ever interacted with, in my quest for dental excellence. Dr. Bui, on the other hand, is the pinnacle of dentistry. Polite. Educated. Patient. Extremely professional. Comical too.
Dr. Bui’s dental expertise, is above and beyond my former dentist care. The meat-market facility, in Bellflower, where borderline witch doctors, who practised there aboriginal “skills” on their un-suspecting clients, should be shut down. My daughter and I have visited Dr. Bui’s office for 3 years now. Prior to  that, neither of us had visited any dentist in the previous 4 years. After mishaps at  dental offices in Long Beach and Bellflower, now we both can breathe a sigh of relief. I would recommend Dr. Bui to any of my friends!

Vanessa G. from Chinatown, Los Angeles, CA (Source: Yelp)


Dr. Bui is amazing!! He welcomed my boyfriend with no insurance, he treated him with the most respect, took care of the problem within a half hour. The staff in the office are always very informative, caring and helpful. Dr. Bui will definitely be our new primary care dentist 🙂

Mustafa U. from Phoenix, AZ (Source: Yelp)


Dr Bui is truly amazing. He is a great dentist: cleans very thoroughly, explains details as he goes along, and knows what he’s doing. He gives the patient different options: novocaine injection, liquid application, etc. He has a great personality and remembers every patient and their family (or maybe Im just special). With his new office in Tustin, he’s even better because the place is really nice. Even the new restroom is amazing. Furthermore, his staff is the friendliest I’ve ever seen. I truly wish all businesses ran like his. Going to him is still worth the drive for me despite the new location

Simone De Lima S. from Irvine, CA (Source: Yelp)


I’ve been going to Dr. Bui for over five years and I’m so excited that we now have a Yelp for him and his amazing staff!!!!!!!! Dr. Bui is always making sure that I’m comfortable and that I understand the treatment plan! Lili, his treatment coordinator, is always knowledgeable and kind! I’ve done all my dental work and also Zoom and if you haven’t tried it, give it a try! Beautiful and white teeth makes you look younger and confident! I always get compliments on my teeth and I owe all to this office! XOXO!

Monserrat Casas (Source: Google)


absolutely love this place. My family and I have been coming here for years. Dr bui is always so kind and listens to our needs. He is careful with my autistic son and my son is not fearful of going to the dentist anymore thanks to him. He and his staff are wonderful ❤️

Dawn D. from Anaheim, CA (Source: Yelp)


I have been a patient of Dr Bui’s for at least 12 years and I absolutely LOVE him!! He takes time to explain procedures and provides all care options. And, I can’t say enough about the staff – Lily and Barbara. Both are exceptional. Over the years, Lily has been extremely helpful. She always treats patients with respect, kindness, and consideration.  I have had a few dental emergencies over the years and I can always count on Lily to get me in to see Dr Bui quickly.  She is fantastic!   I highly recommend Tustin Family & Cosmetic Dentistry.

Victor R. from Santa Ana, CA (Source: Yelp)


I came here for the first time due to a work Injury I was in pain, half of my front tooth was broken due to a plumbing tool sleping off my hand, however as soon as I arrived I noticed Dr Bui was busy with another patient but his receptionist took care of me and she made me feel very comfortable she took the necessary Xrays and sat me down in a comfortable chair as soon as she was done, Dr Bui didn’t make me wait and took care of me right away,  he said I needed a  crown and without hesitation I agree to the treatment, it only took 2 appointments to get it done I’m very happy and satisfied you can’t tell that I have a crown on my front tooth!  I’m  very happy and satisfied with this office, Barbara his assistant is very caring she asked me during the entire procedure if I felt ok, and Dr Bui was gentle and requested nitrous oxide to my workers comp insurance for my extreme anxiety, I recommend anyone for your dental needs especially if you are involved in a work Injury like I was.

Rachel O. from Rancho Santa Margarita, CA (Source: Yelp)


Out of all the dentists I have ever gone to, Dr. Bui is the best. I get nervous when going to the dentist, I’m not going to lie, but I trust Dr. Bui, because he explains/shows everything to me and guides me through all my dental work so that I understand what is going on with my teeth. He doesn’t try to sell you on procedures, and if there are things he recommends you get done, he gives you the choice, and gives you time to think it over.  He is very meticulous, which is an essential quality in a dentist, but most of all, he cares.

I made an appointment with Dr. Bui for Thursday morning after a friend gave a STELLAR recommendation for his office & staff. I have had some bad experiences with dentists and generally have anxiety about going for anything other than a cleaning and she said the people here are caring and gentle and would be perfect for people like me. She also said she has moved multiple times and still continues to come here because they are the best. Now that I’ve experienced it for myself I see why. I had to come in for somewhat of an emergency, my front tooth got re-chipped and I needed it repaired right away. The receptionist Lilly made me an appointment for the very next day first thing in the morning and was extremely accommodating and kind.  Dr. Bui was so nice and explained everything to me, and he got right to work and repaired my tooth to look just like it did before, actually a little better than the previous work. I couldn’t believe how fast he did it and how good it looked. I am very happy with the result and although I just came here for a specific thing I now want to keep coming back and see him as my regular dentist.  A really important detail for me is also is that the office is really pretty inside and decorated nicely and feels warm and welcoming and comfortable, not at all cold or sterile. I didn’t feel anxious at all, more like I was in someone’s living room. I definitely recommend Dr. Bui to anyone.

Helen H. from Stanton, CA (Source: Yelp)


I had my follow-up dentist appt with Dr. Bui, and as expected I was treated like a queen. Mind you, Ive had several other crowns put in before but not like Dr Bui’s exemplary work. In previous years when I had crowns put in, even the permanent ones felt a lil awkward at first, I had to get use to it. However, Dr. Bui’s crown didn’t even feel like a crown, when he glued my porcelain crown in, it felt so natural it was beyond a perfect fit. It felt like my own natural molar. As soon as I was done with the appt I made another appt to get my other crown replaced as it is very old and damaged as well. I’m looking forward to another relaxing day at my dentist office, how often do you hear anyone say that about a dentist appt, not too often thats for sure! Thank you once again Dr. Bui for your excellent service!!!

Janira B. from Hanford, CA (Source: Yelp)


I used to dread going to the dentist until I found Dr. Bui. My husband and I started seeing him in 2004 and since then have moved to the Central Valley but still go to Dr. Bui for dental work. For us, traveling the 4 hours is worth it because it took so long to find a dentist that was caring and knowledgeable. I am a clinical psychologist (and busy mom) so I also enjoy how flexible the staff are in assisting us with scheduling our appointments. My teeth are so sensitive and Dr. Bui always takes the time to make me comfortable during dental procedures. I have to say I enjoy 6 month visits and working with all of the staff at this office. Also, Lily the insurance specialist is on top of everything and the dental assistants are the best! I don’t ever write reviews for yelp but wanted to take the time to let people know Dr. Bui and his team are awesome. I highly recommend this office to anyone needing dental work.

Richard V. from Orange, CA (Source: Yelp)


I’ve never written a review on any company, because I always sensed I was getting a raw deal, but for Dr. Bui (aka “Lakeside Cosmetic Dentistry) writing a review is an honor. I first met Dr. Bui and his fantastic staff, Lily and Christina, about 5 years ago, as a worker’s comp patient, and was rewarded with excellent service.  I never thought I would use them again but I did.  You see, when I lost the same tooth, that which he replaced from my initial visit, because of an on the job accident, there was no doubt who I wanted use. I trust my dental needs only to Dr. Bui and his staff.   Dr. Bui and his staff are the epitome of a well run Dental Office. From a personal greeting from the Office Manager, Lily, when you enter the office, to Christina, the X-Ray Technician, who calms you down and is very patient while taking your X-Rays.  Dr. Bui has assembled a great staff that is friendly, personable and very knowledgeable.  I almost forget they all have beautiful smiles!!   And Finally to Dr. Bui, the best Dentist I’ve ever meant!  Dr. Bui takes his time to know his patient, he did with me.  He makes you feel comfortable and right at home, even if you are at a dentist office.  Before he commences any dental treatment, he discusses the reason why the treatment needs to be done.   After your discussion you come away having a complete understanding, and you know your dental needs will be fully met.  After numerous visits, I’ve never been disappointed. That is why, I’ve made Dr. Bui my personal Dentist, I trust no one with my dental needs except to Dr. Bui, and his fine staff.

Micheal M. from Chino, CA (Source: Yelp)


Another example of Dr. Bui’s ethics and professionalism.  Had an appointment on a Saturday for what I thought was going to end up being a root canal for a bridged tooth.
Showed up and no surprise X-Rays were in order.  After reviewing them Dr. B came in and assessed my issue.Pain coming from a tooth that wasn’t a tooth.  It was a bridged gap.  He explained the tooth I was pressing on was not a tooth.  What?  It hurts when I press on it… confused I ask why does it hurt then when I put pressure on it? He explains again.Sparing you all the long boring details, he prescribed me heavy antibiotics and filed down a “high” point in my bridge that was causing my gums to send a false feeling of a tooth issue.  He told me he did not want do a root canal on a tooth when my problem was a gum issue. Skeptically I accepted his method of process of elimination and left with my Rx scrip in hand.Now three days later my tooth does not ache (gums I should say) because he was SPOT ON.He would have easily made 3 times as much doing a root canal from my insurance, but cares more about his patients and their loyalty and partnership in their care to make a quick buck.I’m so glad to have found Dr. B and would not recommend anyone else!

Mia F. from Huntington Beach, CA (Source: Yelp)


This is a must see dentist. I have a natural fear of dentists and have not gone to one in years so, made an appointment that my friend recommended highly to go see Dr. Bui. It was the best decision I made and Dr. Bui made me feel very comfortable. He explains everything in detail which I loved and appreciated his honesty most of all! He has a wonderful personality, attention to detail is suburb and really made my experience going to a dentist not so scary. And my crowns are perfect! The staff are very friendly and professional, especially the office manager Lily. Lily was amazing and super helpful. Anyone in need of a wonderful dentist, look no further He is the BEST!!

Golnaz D. from Orange, CA (Source: Yelp)


Where do I begin?!?! I love Dr. Bui!!!! I made an appointment after avoiding the dentist for over 5 years, knowing my teeth were in bad shape. I started my dentist visits VERY apprehensive and would almost cry just at the sound of the drill that I could hear in the waiting room. First off, Lilly, the receptionist, is the sweetest, kindest, most friendly person woman ever! She knows a lot about all of the dental procedures and would tell me all about them before anything even got started. While waiting for my appointments, she’ll talk to me about all kinds of things to get my mind off whatever I was going to get done, and she treats me like family after all the visits I’ve made in the last couple of months. She’s fantastic and I love her! Now to the actual dentistry: I had to get 3 or 4 fillings, root canal (which was not done by him), and am now in the process of getting a crown. For my first filling, Dr. Bui went REALLY slowly and calmed my nerves through every step. He talks you through everything, so you’re very aware of everything going on, he numbs you thoroughly, but works quick enough so your mouth isn’t in pain from being open for hours on end. He never makes you do anything you don’t want to do, and will stop as soon as you make the slightest sound of you being in pain.
His dental assistant, Barbara (Barbie?), is just as kind. She asks if you’re okay if she thinks you’re in pain or need a break, and was very kind to my parents, who I dragged there with me my first few times. (I’m a baby, ok?). All in all, I still don’t ENJOY the dentist (who does?) but I love seeing Dr. Bui and his lovely staff. They are seriously the best dental staff I could ever ask for!

Aurora N. from Fullerton, CA (Source: Yelp)


I had zoom whitening this week and I saw results immediately. I would also like to add that I had no sensitivity pain during or after the procedure due to the fluoride toothpaste that Dr. Bui requires you to brush with for a week prior to the procedure. I called around before choosing to go with Dr. Bui and no other dentist offered this. This is part of the reason I choose  to go here. Lilly was great and extremely helpful. She made sure I was comfortable and satisfied. Wish I had done it sooner. So happy with the results and service that I recommended a friend who set an appointment for next week. Thank you Lilly and Dr. Bui!

Aistis R. from Orange, CA (Source: Yelp)


Dr. Bui is hands down the best dentist in all of Orange County!  Don’t even hesitate, there is no comparison! Like myself and all the other people who have received excellent service from the good doctor and have taken the time to give this man 5 stars, we do this because we mean it! Unlike some other dentists that you may have encountered Dr. Bui takes the time to explain in detail the procedure and is glad to answer every you can throw at him! Don’t look any further, this is the dentist you are looking for!

Alison L. from Orange, CA (Source: Yelp)


With three growing girls, it has been a great challenge finding a dentist that will accommodate the whole family.  Dr. Bui and his staff, Lily and Christina, have gone out of their way to help us.  My husband was traumatized from childhood and one of our daughters was the same but when we came to Dr. Bui’s office, all their fears were dissolved by Dr. Bui’s caring attention.  He knows what he is doing and he deserves a gold star for handling my daughter so carefully.  I specially like how Dr. Bui always consults with me first on all the work the kids are getting done letting us make the decisions based on our daughter’s tolerance level for that day.  When we were going through braces, Dr. Bui’s office was extremely helpful with recommendations and cleanings.  To top it all off, Dr. Bui’s services are easy on the wallet thanks to his friendly and caring staff.  So I say to you, Have no fear, Dr. Bui and staff are here.
