Rochelle S. from Orange County, CA (Source: Yelp)


I love Dr Baek and his staff! I’ve been going to his office since 2015. The staff is great especially Tom, super friendly. He always remembers me whenever I come in or call. The office is always very clean, and the patient chairs are massage chairs! Really helps me relax when I’m anxious about getting dental work. Dr. Baek believes that no dentistry is the best dentistry, which I admire. Dr. Baek has a warm and funny personality and you can see he genuinely cares about his patients. Also, their hours are great and they work with my work schedule. I’ve never had to wait to see Dr. Baek whenever I come in for my appointment. I highly recommend him to anyone looking for quality dental care.

I’ve had continuous positive experiences with Dr. Baek, Tom, and his nurse/hygienist staff for several years now. Before coming here, I was shopping around for a check-up and general cleaning, but felt that other dentist offices were pushing unnecessary services on me that were costly (mouth guard, deep cleaning, etc.) However, Dr. Baek is honest and straightforward, while looking out for the longevity of my oral health. Even more, the doctor and staff are accommodating to the patient’s needs and sincere in their services. I would most definitely recommend a visit to Dr. Baek’s office.

Esther J. from Buena Park, CA (Source: Yelp)


Dr. Beak and his staff are very professional & friendly. Over the past year, I got several treatments done and I’ve been satisfied every time. Besides being skillful at what he does, Dr. Baek knows how to keep his patients smiling~

Tony K. from Honolulu, HI (Source: Yelp)


Dr. Baek is on the best dentists out there!  He helped me replace some of my broken fillings and repaired some chipped teeth.  I was comfortable during the entire procedure and he was always checking to make sure I was OK during the appointment.  The fillings were done with the white composite resins and he did a great cosmetic job because I couldn’t tell where he fixed the teeth because they were so well blended in (…).

Jasmine C. from Buena Park, CA (Source: Yelp)


Great overall experience! From making appointments to sitting in the exam chair, everything went smoothly and very pleasant! I can tell they really try to make it a good experience for all patients from the dim, not too scary bright, lighting in the exam room to the calming classical music they play. They also have really top-notch equipment! It was my first time getting a panoramic x-ray of my mouth and digital photos so the doctor can explain the clinical point of view of my teeth. They had a huge screen to show me everything so I can see exactly what Dr. Baek was talking about. He’s also really thorough in explaining not only what issues I had going on but also the cause and practical prevention/solutions.

Who likes going to the dentist? Nobody right? Dr. Baek is awesome. He takes the dreadful experience out of going to the dentist. Dr. Baek is very friendly to explain what he was going to do and made me feel at ease. I needed a root canal. Growing up we hear horror stories about root canals. And you know what? I felt no pain what so ever. By far Dr. Baek has been the best dentist I’ve been too. He wants to help and his staff is very helpful and friendly (…). Dr. Baek will be my dentist from here on out. And I will bring my son here for his 1st dentist appointment. From a person, who hates the dentist, I highly recommend Dr. Baek.

Joe M. from Brea, CA (Source: Yelp)


This is the most enjoyable and least stressful experience that I have had visiting the dentist. Dr. Baek gave me a quick and thorough diagnosis of the things that needed fixing I had and gave me a concise and thorough timeline and treatment plan to alleviate these problems. Each treatment that I had was comfortable and pleasant and the staff made every visit enjoyable.

I would highly recommend patronizing Dr. Beak’s practice and as strange as it is to say I am actually looking forward to my next visit to reconnect with the staff and have another great experience with a doctor who really cares.

Ashley J. from Fullerton, CA (Source: Yelp)


I hadn’t been to the dentist for an embarrassing amount of time and I was terrified. My husband, in-laws, stepchildren and their mom and her whole family are Dr. Baek’s patients and had nothing but wonderful things to say about him and his staff. They are efficient, gentle and most importantly productive. I would recommend them to anyone and everyone. Thank you all for helping me overcome my fears and helping me immensely!

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


(…) if you’re looking for a dentist that will seriously educate you, and put your thoughts first before his- Dr. Baek is the man! He spent real quality time with me thoroughly explaining in detail what was going on in my mouth and what I could expect undergoing my cosmetic procedure.
not only was he providing me with info, he had a way about him that made me feel at ease about everything that I was getting done!

Chris Y. from Los Angeles, CA (Source: Yelp)


I’ve been making the trip to Buena Park from la because Dr. Baek is really that good. He’s very knowledgable, professional and overall a really good guy. Dr. Baek isn’t only my dentist, he’s a good friend. His staff is awesome and you’ll love the little touches from the massage chairs to the care packages he gives you every visit. You won’t find a better dentist and crew in OC or LA!

Melissa M. from Buena Park, CA (Source: Yelp)


I’ve been coming to this dentist off and on for a couple of years. Dr. Baek is a great dentist and so is his assistants 🙂 and the office manager Tom is also very nice. Dr. Baek is very gentle, always asking if I’m ok. Recently I needed to get 2 root canals done before I have surgery, Dr. Baek and Tom worked with me to make sure I got them done before my procedure. . I even tried to reschedule and he said nope were on a deadline lol.. Again great dentist, assistants and office manager. The office is very nice as well

Chong Y. from Buena Park, CA (Source: Yelp)


(…) Dr Baek made sure during the whole treatment, that I was ok, by asking me every ten minutes or so if I was. Before the procedure, he also explains EXACTLY what he plans to do so there are no surprises. He also will tell you during the procedure what I might feel or hear(i.e. slight pressure, drilling sounds, water, etc…) before each part. How awesome is that? Don’t get me wrong, I was still a nervous wreck, but the way Dr Baek runs his practice, is all about the patient. You are his first priority.

I am so glad I found this dentistry and I feel a lot less nervous about going back for my next visits! I have already started recommending him to my friends and family and I even got my girlfriend to go to his office for a check-up! If you’re in the northern OC area and in search of a dentist, Dr Baek is the guy to go to.

April Y. from Buena Park, CA (Source: Yelp)


(…)I’ve been going to Dr. Baek for the past two years, and I don’t regret it! (…)

Dr. Baek is not pushy with any type of service. He will let you know the best options, and makes you feel so comfortable. During procedures, he’s very gentle and is concerned about his patients. He always checks up on how I feel every few minutes.

If you’re looking for a new dentist, I would highly recommend Dr. Baek!

Yeon Ju K. from Pasadena, CA (Source: Yelp)


I’ve been a regular at Dr. Baek’s for 10 years now and he’s by far the best dentist I’ve ever had. I don’t live in Buena Park but I make the 30-40min drive.  Dr. Baek is very friendly and thorough. If you’re in search of a good dentist I think this is the place to be.

Vick C. from Anaheim, CA (Source: Yelp)


This is a great place especially if you don’t enjoy going to the Dentist. Dr. Baek is patient and caring and makes sure you aren’t in discomfort while he’s performing an extraction or root canal. I feel comfortable going here and tell all my friends. I live in south Orange County and drive up to Buena Park on the 5fwy. They are flexible with appointments and will try to accommodate your work schedule. Nice office and modern equipment. You can’t go wrong stopping by here.

So I needed a root canal for the first time and was terrified after hearing horror stories from friends and family. Dr. Baek and his staff assured me I was in good hands. Also, I was recommended by another patient of his who spoke highly of him and his office so I was a little more at ease.

Honestly, I haven’t laughed at the dentist this much in my life! No discomfort and Dr. Baek asked how I was doing pain-wise throughout the whole procedure. Kept me calm and relaxed. Before I knew it we’re done. This is literally one of the best experiences I’ve had at the dentist. Funny how it was for the procedure I was most scared of.

I highly recommend Dr. Baek. Truly an office of kind professionals.

Terence C. from Long Beach, CA (Source: Yelp)


I love this dentist, he really cares and knows what he’s doing. He’s very prompt and personable and really attends to his patients. He also has new tech and updated rooms compared to my previous dentists. His billing system also is awesome, he’ll work with you on payments, unlike others where they see you as dollar bills. He really cares bottom line!

Justin Fields (Source: Google)


I came to Dr. Baek’s office when I really needed a dentist and had not been to one in over 10 years due to a bad experience when I was younger. He understood where I was coming from and took the time to explain everything I needed done and what to expect from it. Truly a very good dentist and best experience I have ever had with a dentist. He treats you like family and finds out how you are doing every time. You never feel rushed or like your bothering them to be there. His staff is friendly and caring as well. Never had an issue since going with his office. I just want to say thank you to Dr. Baek and his staff for everything they have done for me.

Helen S. from Buena Park, CA (Source: Yelp)


Dr Baek, or Moses as we call him, has been our family dentist in Buena Park since soon after he opened his practice.  We’ve been very happy with his expertise, his sense of humor, his massaging dental chairs and last but not least, his entire staff, including Jeung, his wife, Tom, Betty and the others.  His office is equipped with state-of-the-art digital x-ray and camera, and he is always up on the latest in innovations within the dental community.  With many dental businesses from which to choose in the Buena Park area, we consider ourselves fortunate to have found Dr. Baek.
He is not only our dentist but more importantly, he and Jeung are great friends.

Esther Jeong (Source: Google)


I’ve had some bad experiences with other dentists. So, I was very nervous and worried before going to this dentist. But, After I was checked in this dental, I could come home with a smile. Dr. Baek is so kind and the staffs are very friendly and professional.

Mimi A. from Fullerton, CA (Source: Yelp)


Dr Baek is the most kind, honest and gifted dentist. Hard to come by nowadays. I have been coming here for 3 years now and have brought my family here as well. I don’t write reviews often. I am writing this because I owe it to everyone who is looking for a one of a kind dentist to come and visit Dr Baek’s office and see for yourself. If you have children, he is awesome with them- has little ones of his own. He is not only a professional in dentistry but he treats you like family (…).

T. P. from Buena Park, CA (Source: Yelp)


I hate going to the dentist. But Dr. Baek makes it not so bad. He is caring and gentle. His facilities are super clean and modern. I recommend him to family and friends all the time. He is very knowledgeable and supportive of your dental needs!

Mark Lee (Source: Google)


Dr. Baek is great. Gives you straight up answers. Office manager is also good, knows his stuff when it comes to insurance and billing issues and such. First time I’ve actually felt comfortable at the dentist office (…).

Robert H. from La Habra, CA (Source: Yelp)


Dr. Baek is professional, well educated, people-oriented, and uses the most modern equipment & techniques. His work quality is outstanding. It is a pleasure to have a dentist who takes personal pride in delivering excellent patient care by delivering excellent results.
I’m no youngster and due to relocations by my work have had 9 different dentists in my 52 years. Dr. Baek is far ahead of all of them, including 2 in Beverly Hills. He is personable and will answer any question, honestly and in as much detail as you want. Go there if you want the best care and best results at a reasonable cost.

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


(…) I’m a wuss when it comes to tolerance of pain in the mouth, but honestly, I hardly felt a thing.  I actually look forward to my checkups as not only do I get great service and care, but I can actually converse with Dr Baek and catch up and see how he’s been.  That’s how great Dr Baek’s office is, the guy has me coming back for more.  Never in my life, could I ever picture myself looking forward to visiting the dentist’s office.

Dr BAEK dentistry is a first-class dentistry my family has been going over the last 6+ years.  His staff has always been professional, courteous, and welcoming.  Making appointments have been seamless and the service my family has been receiving has been phenomenal.  I know he uses the state of art technology in his office.  I put my trust in the Doctor with all dental needs for my family.  There were a few times my son had accidents that required immediate attention on dental work.  Not only did the doctor and staff went above and beyond to provide care, the doctor did everything he could to save and preserve.  My son has said this is his favorite place to come and loves to see the doctor on friendship level at times.  Dr Baek is a professional and patient caring doctor at all times proving all options and understanding of service for his patients.  It will be a tough decision to look for another doctor in this area, since we are in good hands.

Polarbear F. from Fullerton, CA (Source: Yelp)


They have a friendly staff and were always willing to answer my questions. They have a modern set up and my x-rays were up on the monitor at my chair, this made it much easier to see what the dentist was talking about. The facility is clean and neat. I will continue to use this office. This place is unbelievable!  Dr. Baek and his staff give the 5-star treatments every time. He is extremely professional, and truly is an artist when it comes to cosmetic dentistry. He’s definitely one of the top dentists in OC, if not the best.

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


Awesome doctor and staff. I avoided going to the dentist for many years, because it’s always been an unpleasant ordeal. Dr. Baek really takes the time to make his patients feel comfortable, and takes the time to explain treatment options. I had a root canal done, and throughout the procedure he took the time to make sure that I was okay. I couldn’t recommend him more.

Hiroko C. from Buena Park, CA (Source: Yelp)


We LOVE Dr. Baek!! Such a great dentist, but more than that, he is a great person!
Our whole family of 6 comes here and he really takes such good care of us!
Highly recommend if you’re looking for a long term dentist!

Karina D. from Bloomington, CA (Source: Yelp)


Dr. Baek was so nice to me and I can tell he really cared about me by how he was very sorry he caused me pain by picking at a cavity lol. He goes through everything that needs to be done thoroughly and makes you feel well taken care of. His staff is also very kind and provide the best dental service I’ve ever had; I left wanting to cry because I’ve always had bad experiences with dentists, I will definitely have all my dental work done with him!

Tejsah T. from Los Angeles, CA (Source: Yelp)


The best dentist ever!! I got over my fears of the dentist from this dentist right here!! You seriously can’t even feel his needle pokes like most dental places.  Super nice and attentive.  I’ve been with Dr. Baek for about 5 years now and I would not go anywhere else.  Believe me, I grew up hating the dentist and I went to different ones in the last 10 years because I could never find the right dentist but when I found Dr. Baek, it was my prayers to get over my fears of the dentist.

Tamee M. from Seal Beach, CA (Source: Yelp)


(…) My husband and I have been seeing Dr. Baek for a little over a year, I believe.  I’ve been to so many dentists and never enjoyed the experience. I actually like going to the dentist now, haha!

Dr. Baek is so gentle and caring and has a great office staff to boot!  I had my first root canal a few weeks ago and I was so worked up over how painful it was going to be and a little freaked out.  It was all for nothing!  Honestly, I hardly felt a thing and Dr. B let me know exactly what he was doing and was super gentle.  I didn’t have any pain during or after the procedure 🙂 (…)

(…) Dr. Baek is very friendly, professional, kind, and knowledgeable at his practice. He ensures that I understand what is going on, and he takes the time to explain everything very thoroughly. He even answers all the questions that I have (and I have a lot..) and goes above and beyond. He has never pressured me to agree to any procedure (as have other dentists from my past) and I know that I can trust him because of that. Tom, the office manager, is also helpful and informs me of what my insurance options are and gives me a breakdown of how I can maximize my insurance benefits so my wallet can be happy. Tom is courteous and welcoming each time I come into the office, as is Dr. Baek and the other dental assistants there.

In conclusion, I am SO glad that I can call Dr. Baek my dentist and I HIGHLY recommend him to everyone! Please give his office a visit and you will see why I and so many other people are so satisfied! 🙂

Dr. Baek is the very best! We moved to Chicago but we still see him when we come back to visit family in California. He is incredibly knowledgeable, sweet, and personable. Although he has many patients, he always remembers my daughter and my husband’s name and asks how they are doing- which adds a nice personal touch. My teeth guard broke and no one else makes one like his in Chicago (thin and unnoticeable), so I came back to see him and he replaced it free of charge. He never tries to sell or push me to buy anything.

Tom, his receptionist, is also always very responsive and friendly. He has a sort of zen vibe to him. The rest of Dr. Baek’s staff is always very friendly as well. The office is modern and extremely clean, and my office visit always feel like a mini spa day. They have massage chairs while they play soothing music and you get a hot towel at the end of your visit. What more can a busy mom ask for?!? Lol. If I could give them more stars  I would.
