Dr. Kim is an amazing dentist and has excellent bedside manners. He explains everything in detail and offers options that will suit your budget. He does not try to upsell additional procedures that are not needed and is honest and upfront. My teeth and gums are healthy thanks to Dr.Kim. He also helped my husband with new dental implants. My husband experienced minimal pain and downtime from the implants and his teeth are perfect now. read more

Since I didn't grow up here I didn't have a dentist. I tried 5 different dentist before settling here. Dr Kim. Never makes you do unnecessary procedures. Not only for the cost, but I like my natural teeth I don't want to shave them or pull them for no reason. I had a chip which 5 different dentist said a filling won't last in that area we need to do a veneer. Dr Kim told me this is a very easy filling. 2+ years later my filling is still there. And I come here regularly for check up and cleaning. Also the dental hygienist is one of the best I've had. Usually my gums are bleeding and in pain after a cleaning. Here I've never had any bleeding and he is so polite and kind. Not to mention the front desk, scheduling, everyone from the front to back working is so friendly nice professional here. Wish every dentist was like this so others could experience what you're supposed to at a dentist read more

Great dentist and nice staff! Always take the time to answer all your questions. Helpful that they are open on Saturdays as well. Office is nice and clean. I have tried numerous dentists around the Brea/Fullerton before finding this one. Thank you, Dr. Kim and staff!!! read more

I really love this place so much. Everyone is very helpful very resourceful and it's peaceful and quite inside that's key ! Most times it isn't pleasant to visit a dentist but this place makes you some how feel calm and relaxed read more

Dr. Kim is an answered prayer! I have been looking for a good honest dentist all my life! I was quoted thousands of dollars elsewhere and it didn't sit right with me. So I was recommended to come here by my mom and honestly we both praised God for leading us to this place! I may sound very dramatic, but I think most people would agree that finding a good dentist is like finding a needle in a haystack! I am recommending him to all my friends and family and whoever needs the greatest dentist in the world! Thank you Dr. Kim! Oh, and the front office ladies are super nice too! read more

By far the BEST DENTIST! I'm very nervous about visiting a dentist not because I'm scared of a dentist. I've had too many experiences of a bad doctor charging my insurance company for the treatment that I did not get. Dr. Kim is honest and gentle! I've been going to Dr. Kim for about 7 years and I've introduced him to many of my friends. They are all very happy with Dr. Kim! One friend had her teeth all messed up by another dentist and she got it fixed by Dr. Kim. read more

My entire family goes to Dr Kim for dental care. He's not only a very nice person but his fees are very reasonable His staff is also outstanding. I highly recommend them. read more

Absolutely the best dentist I've ever been to. I don't give out 5 stars easily. I had a root canal procedure done with Dr. Kim and the procedure went incredibly smooth, and without pain. Dr. Kim has an extremely steady hand! I have been recommending all my family and friends to go to Dr. Kim. He is a very honest dentist and will not push procedures on you just to make a buck. He is Korean and his English is excellent. There are no communication barriers whatsoever. He wants to keep you happy and will take time to explain things. His dental assistants/hygenist are on point and flow perfectly with Dr. Kim's procedures. His staff is amazing and they do a great job of handling the scheduling and transactional side if things. read more

Merry Christmas and a happy New Year to the wonderful staff at Byoung Kim DDS. They definitely changed my life for the better. Run, don't walk to this office if you want the best in dentistry, professionalism, courtesy ,customer service and sophisticated technology. Thank you! read more

Let me tell you about this Dentist. He is the best hands down. His name should be seriously Dr. Gentle. I had never had to have teeth work done until just recently. I was so scared, he was so gentle and his technique is amazing. My youngest son saw this and finally had the confidence to have dental work done that we had tried 3x previously but he'd start hyperventilating when they would strap him and give him the gas. Dr. Kim didn't have to do any of that. He was so amazing with him. I also love the lady that works in the front very sweet and professional. Highly recommend this dentist and staff!!! read more

Best dentist and staff ever! No wait time and super quick and informative with the whole procedure. Painless fillings and always checking up on me! Definitely recommend to everyone read more

very professional and take care all situations ... nice attention and comfortable to be attended with Dr Kim

High tech, clean and modern environment . He made me a new smile with his new technology!! He is very detail, kind and sincere, rarely can find in this field. Thank u Dr Kim for your service! All my family is very happy with him read more

Dr. Byoung J. Daniel Kim gave me a huge smile! He replaced three of my old silver fillings with one-hour-ready pure ceramic CEREC crowns and the entire process, including the (no insurance but I did have savings) price was painless! How can I say THAT? I received value for the dollar in so many ways, and it's not often one can say that living in Southern California. His passion for, dedication to and skill in his dentistry showed in his patient concern, personable demeanor and end result: a very happy customer! Dr. Kim was very patient, gentle, kind, empathetic and accommodating. His staff was professional, positive and clearly liked working with him. You even fill out a form letting him know what is most important to you when getting dental work. My first concern was gentleness during the procedure. And he delivered. For example, getting to my needy teeth was tricky for both of us: All were in the back and one was a molar. Dr. Kim inserted anesthesia right near each tooth with a small jack-hammer-like device that delivered fast and numbed quickly--no more long needle jammed painfully into the back of your mouth to numb your face for a half day. He also placed a clear protective plastic/cotton mask over my eyes and nose--dental smells be gone! After old-filling-extraction and tooth prep, he photographed the tooth with a tiny elongated camera. And on the computer screen in front of me, up popped an image of the area to be filled. I watched the full process as the computer went to work analyzing at all angles in 3-D for a precise match, using a single block of ceramic. This onsite milling saved me the extra steps, time and costs of dealing with an offsite manufacturing laboratory, temporary crown and return visits. The CEREC crown, ready in less than an hour, covers my entire tooth, all the way around, down to the gumline. Dr. Kim's skill also showed in his crown-color match to my natural teeth. The crowns look so real, even my housemate can't tell the difference. Like most patients, I was anxious about dental work. Not any more. I now have great faith in Dr. Kim's skills and passion for his work. Each time, I was ready and alert after one visit, no lingering numbness, no thick tongue or puffy cheek, no sensitivity to food or drink temperatures, no after aches. I actually felt great! Prior dental estimates for the same 3 teeth#s and conditions, but with inlays and one lab manufactured noble-metal fused crown, ranged from $1,450 to nearly $8,000. I found Dr. Kim through his display ad in our local Pennysaver. He accepts CareCredit, which is a non-credit-card monthly payment plan, sometimes without interest if you qualify. I also researched non-employer, individual dental plans, but the combined annual monthly premiums and specific discounted treatment price for my specific teeth #s were higher than direct-dental-pay--and did not cover the CEREC technology. I never thought I'd be "singing the praises" of a dentist, but Dr. Kim is really exceptional and I recommend him to everyone who complains about their teeth needing work. So here you have it. Now give it to Dr. Kim! Including in English, Korean and Spanish. Heck, try sign language, too! He and his staff are prepared! He'll give you your best smile. read more

Dr. Kim is the best! Always remembers small nuances I have with my teeth and has helped my brother and mom with their teeth as well. Definitely recommend. read more

My best friend recommended Dr. Kim to me when I mentioned that I possibly needed dental work. I went in for a cleaning and X-rays. It turned out I needed a root canal. I've never had a root canal and was fiercely dreading it, but the procedure was a lot shorter than I expected, there was zero pain and minimal discomfort. Dr. Kim and his staff are all very kind, assuring, and very attentive. I wish I had started going to him many years ago. read more

Just found Dr. Kim. I found him from all of his positive reviews on yelp. Extremely honest, upfront, efficient and most importantly no "up selling " for services that are we're not necessary for my oral health. Loved their high tech x ray machine. No need to bite onto multiple plastic guides! read more

Absolutely! Dr Kim takes care of what you need and doesn't "cross sell"! Proficient assistants! Very pleased with their work. They did a beautiful redo of our neighbor's whole mouth. read more

I came here for two crowns and root canals. The process was pain free and Dr. Kim was very polite and kind. The staff and dental assistants are also very nice and friendly. My experience was very easy and there was no wait time. I would definitely recommend this dentist to everyone. read more

Dr. Kim is THE best dentist in the area. I found him when I was looking for someone to relieve a horrible toothache. He saw me on very short notice and knew exactly what to do. Since then I've gone in for other work and the visits are always pleasant, professional, and as short as they can be. His work is excellent and his staff is nice and understanding. read more

Great service. You'll be in and out very quick. The staff are all very nice, friendly, and welcoming. Especially Dr. Kim. Dr. Kim is the nicest person ever. read more

Dr.Kim is the best dentist I've ever met. Always good skill and pianless. Two thumbs up!! read more

Dr Kim has been my primary Dentist for two years. He is one of the most skilled dentist's that I have gone to. He takes his time with you and does a superior job in all of his dental work. I might also add that the office staff is helpful and easy to work with. I personally would not go anywhere else. Warner G. read more

The dentist is highly skilled and staffs are friendly. It's one of the main reasons why my wife and myself go there. But there are other reasons too. Never over booking like some airlines do. We always enjoy somewhat relaxed air because Dr. Kim gives patients enough time for them to feel like at home. He practiced many years in a South American country and started practice here in California years' ago. He not only speaks English but also Spanish and Korean as fluently as English. I would never hesitate to recommend ths smiling Dr. Kim to any one. read more

I don't normally give reviews but I had to share my experience with this dentist. I went in for a root canal 4 days ago and like most people I was dreading the procedure because of past bad experiences with root canals. Dr Kim was amazing. The whole thing was super smooth with zero pain and the best part is that I have had no pain and haven't had to take pain medication. Both the dr and his staff are very nice and polite read more

Dr. Kim has been our family dentist for the past 10 years, we have moved from Los Angeles to Portland Oregon. Was not happy with my dentist options in Portland. Made an appt with Dr. Kim (he was kind enough to make time for me on a Saturday) and flew in for the weekend, so so very happy I did!!!! Great staff and of course Dr. Kim did a super job on the teeth as usual. Proud to say I'm one (of many) of Dr. Kim's SMILES . read more

Dr. Kim is wonderful. He does quality work and for an affordable price. He made the whole experience comfortable.

Came in for an appointment at 2:00 which was confirmed the previous day. Was told to wait when I arrived just past 2:00... 2:02 to be exact. Around 20 minutes later I was told that they were getting ready for me and it shouldn't be much longer. About 10 minutes later I'm finally seated. Assistant puts on my bib and leaves and I waites again anticipating the doctor to come in at any moment. Only he doesn't... At close to 2:50 I am feeling very disrespected and upset at the wait so I went to the front desk to ask what is going on. Receptionist tells me she didn't know I was waiting that long and there were emergency appointments causing the doctors delay. At no point was I told this and given a heads up that there would be a delay. Just kept waiting. They try to speed things up by telling me the assistant can do it at that moment. I have my reservations but at this point it's closing in on an hour since I've arrived so I just go with it. She tries by herself to do the cleaning... Meaning she isn't able to clean and also pump all the fluids out of my mouth. At this point I'm about to just leave when doctor finally walks in and finishes the cleaning. Told them as I finish I don't plan to return and receptionist says they are billing my insurance for services rendered. I'm not scummy enough to get a cleaning and not pay. Ive never felt so disrespected and treated like my time is not important. Ive had waits at dentists offices but they've almost always not very long and if it's running even 10 minutes I'm always told about it. I give 2 stars because the dentist is skilled and does his job well. I also assume he doesn't have too much involvement in how the patients are booked. Clearly out of greed or ignorance they overbooked but they also did a terrible job of keeping me informed of the delay. Wont be coming here again and will be telling my immediate and extended family who come here about how poorly I was treated. read more

A few months ago my prior dentist had botched my crown and I ended up needing an emergency root canal. My friends referred me to Dr. Kim which I called and was able to see him that day. He was able to do a root canal right away and I was able to get immediate relief from the pain. He was really gentle and I didn't even feel the needle at all. The root canal procedure was not scary or painful and I was out the door in an hour. Dr. Kim is very professional, kind and gentle with your teeth. I live in Irvine and drive up to Fullerton to see him now. I just had my first cleaning and it was the gentlest cleaning I had ever experience. He was super thorough too! Highly recommend!! Thank you Dr. Kim and staff!! read more

My mom introduced me to this place and I'm very happy with all of my experiences here so far. Dr Kim is very friendly and professional and the office is clean and modern. I would highly recommend this dentist to everyone! read more

The staff is friendly and Dr. Kim is very professional, personable and compassionate. Skilled staff and state-of-the-art equipment in a stylish office. He is very knowledgeable and very efficient, and good with senior citizens I highly recommend him. read more

Love love love this dental group. Attention all yelpers......Honest dentist alert!!!! Does amazing work and extremely fair cash patient prices. He does not try to over sell, or over diagnosis. I take my whole family here and refer everyone I know who is in search of a good and honest a dentist (which is impossible to find nowadays). Dr Kim is also extremely gentle which was very important to me because I hate going. He makes it easy I now go each quarter for my cleanings. My girlfriend needed extractions so I sent her, she also loved them. Go here You will not regret going. read more

Dr. Kim is so kind and you can tell he knows what he's doing. Even though it's a decent ways from LA (where I go to school), it's always worth the drive. Fillings are super fast and he will take the time to polish down and add as needed so that you feel as comfortable as possible. My mom has dental problems and has been several times for root canals (making the trip down from the SF Bay Area to LA just for this). Dr. Kim is also trilingual- he speaks Korean, Spanish and English (did his DDS in Argentina), so you can speak whichever you feel most comfortable with. read more
