I've been coming here for 3 years for general dental care and Invisalign treatment. (I just finished my Invisalign treatment!). Dr. Lee and staff are courteous and take care of things without much hassle. My gums are sensitive and after the first teeth cleaning, I requested future cleanings be gentler, so they promptly got me a special hygienist and future cleanings were good! Invisalign process was fairly straight forward without any hassles. Each aligner (or "tray" as they call it) was adjusted just enough to move my teeth without causing too much pain. Much appreciated! I'm also thankful that the front office staff took the time to put up with my work place's HSA (Health Savings Account) overly nit-picky reimbursement process. I plan on staying here for the long run. read more

My husband has been going to Zin Dental for about three years now. I've suggested switching to a dentist closer to our home, but he insists on coming here because the service is consistently high-quality and exceptional. Huge thanks to Ms. June and Dr. Lee for always being so welcoming, kind, and generous. We truly appreciate the care you provide! read more

I was scared of the dentist for most of my life, but not anymore. After seeing Dr. Lee, everything changed. He is extremely professional and patient, and most importantly, his skills are outstanding. I've had a regular tooth extraction, a crown, and two wisdom teeth removed, and every procedure went smoothly with no side effects afterward. The dental hygienists are also highly skilled and professional. In addition, the office manager, Mrs. Lee, is very caring and honest. She never recommends unnecessary treatments just to make money. The nurses are friendly, professional, and make you feel at ease. I would highly recommend Zin Dental to anyone. read more

Thank you to the absolute best dentist and the most wonderful staff! Everyone was so genuinely kind, patient, and friendly--it made going to the dentist actually enjoyable. I can't recommend this place enough. Grateful for such great care! read more

The doctor is ridiculous. He thinks he's the best doctor and he deserves to be treated as king or something. He wasn't like that in the beginning but I guess he has enough customers. Only thing I ask was other dental has cheaper price with same procedure what would be the difference? He said he's skill is the best so he has to right to charge the higher price. Up to here is ok because it is his office. The problem is after this. He said that he is so disappointed that I asked that question and I have no right to ask that question. Why can I ask when price is double as other dental clinic? Also, he doesn't have skills that I want to pay double for. My mom's implants had problem after 3 years. read more

I've been coming here for 4 years and have always had great experiences. Dr. Lee is gentle, patient, and knowledgeable, which always makes me feel comfortable.

I would definitely recommend this place to anyone looking for high-quality dental care! Thank you for the amazing care!! read more

Hubby said equipment are high tech and staff were friendly and helpful. Will recommend this place.

Miss June and Dr. Lee from Zin Dental Group are the greatest!! Miss June is professional and courteous when speaking to you and scheduling your appointments and Dr. Lee is also, courteous and extremely professional when speaking with you and gentle when working with you. He explains or walks you through the procedure in detail what the work will entail. No surprises at all!! My crown was done within a week and I have no residual ache and it looks great!! I would recommend Dr. Lee and Staff at Zin Dental Group anytime!! read more

My new go-to dentist for teeth cleanings. The entire staff is amazing and very helpful when it came to teeth care. I've been to other dentists in the passed who only cared about making times work for their schedules and finding any procedure to get that extra dollar from you. I never felt that once at with Dr. Lee and his staff. The receptionist June is very friendly and will work with your schedule to get you an appointment and find you the best possible options in regards to costs. I did my teeth cleaning with Dr. Lee and he was very informative of how to keep your teeth healthy. More in-depth than other dentists I have been to, and really goes in to detail. Was in and out of my appointment within 45 minutes, and had to wait about 5 minutes before getting called in. Great location across the street from DBHS, and will definitely be coming back. read more

My son and I love this office I"m really scared of the dentist Dr. Lee and his staff were so welcoming and made me feel as ease... Their office staff is organized , clean and Very friendly and treats us like family I've already recommend them to three of my family Thanks to Zin dental  team! read more

The doctor is great, and the advice given was very good. The nurses are also wonderful. However, I just found out today that a dental cleaning can be completed in less than ten minutes. She was rough as hell!! Throughout the procedure, apart from saying "ah" three times to remind me to open my mouth wider(because I was so uncomfortable and couldn't talk), the only thing she said was to remind me that I could drink water ten minutes after rinsing. Her technique felt like she needed to finish a wood carving immediately, and I was just a piece of wood. I had to pull the suction tube out of my throat by myself, but she remained indifferent. From her actions, I felt that she either hated me or hated her job. But this was my first visit, and she didn't say a word to me! After the cleaning, she immediately ran out while on a phone call, leaving only a receptionist on the phone and another nicer nurse cleaning up. When I got home, I found that my gums were broken in at least two places and were still bleeding. The reason I'm not giving 1 start is the doctor and other nurses are wonderful. read more

I normally don't write reviews and especially did not expect me to write one for a dentist, but HEAR ME OUT! I recently visited Dr. Lee's Dental Clinic to address my teeth grinding problem, which had left my teeth looking sharp and really ugly. From the moment I walked in, I felt welcomed and cared for by the amazing staff. It is actually very heartwarming how they always have smiles and kindness EVERYTIME I walk in! The clinic's environment was clean, modern, and comfortable. Jenny, the hygienist, was incredibly professional and compassionate. She also taught me how to brush my teeth properly. I did not know I was brushing my teeth wrongly this whole time No wonder why I felt like I had a bad breath I also have something to say about Dr. Lee! He was amazing, speaking both English and Korean fluently, which greatly helped my parents understand the procedures and aftercare. My parents LOVED him! He was also talking me to me from time to time to help me calm down with my anxiety The fitting for my night guard was precise and comfortable, and I received thorough aftercare instructions. It came out super fast!! Since using the night guard, I've noticed a significant improvement in my sleep quality and the condition of my teeth. The clinic uses the latest dental technology, and Dr. Lee was excellent at educating me about my dental health. I highly recommend Zin Dental to anyone struggling with teeth grinding or other dental issues. Thank you guys!!! read more

I was trying to find a good dentist for my father-in-law and was referred to Dr. Lee by a coworker. What really surprised me was Dr. Lee's honesty - our previous dentist told me that my father-in-law needs to get multiple treatments done on his teeth. When I asked Dr. Lee, he said only one was needed. The procedure went well and my in-law said he felt very comfortable sitting through it. Would definitely recommend. FYI, there's another Zin Dental in Garden Grove that we got confused with - apparently these two aren't related so make sure you go to the location in Diamond Bar. read more

I have been going around different dentists throughout my life and I finally found a dentist I can trust and feel comfortable. Here are my top 5 reasons why I decided to settle. 1. Dr. Lee and his staffs tried their best to minimize the cost for me. He tried to eliminate unnecessary cost and find the best way to optimize the cost & treatment for my teeth. 2. Dr. Lee is knowledgeable, compassionate and carrying person. I asked lots of questions and every time I visit and I always get a perfect answer and found a good solution. 3. Their equipment seemed to be advanced than the others. Their ex-ray could catch something that my other dentist could not catch. 4. His staff is very friendly and well trained. 5. He really has a magic hands. I do not know how he did it but I did not feel any pain when he was did the injection. My major treatment was removing a molar tooth and placing an implant. He offered me with Straumann which I was not really aware of so I decided to ask a close friend of mine who is a dentist in New York and she explained that Straumann is the best one out there. Also, I did some research about the company and found out that they are Swiss company. Being in the luxury watch industry for quite a while, I had experienced Swiss Craftsmanship of crafting tiny bolts and nuts for those high-end watches so was convinced that they will craft the best one as well so I decided to move on with Straumann. I really have to say so far I am 100% satisfied. It would be great if I have met Dr. Lee earlier so I could have much healthier teeth. I would highly recommend to seem him and do not make the mistake that I made. read more

Going to the dentist is as low as it gets on my to do list, but when I started experiencing some pain with a previous root canal, I knew I had to book an appointment. After spending countless hours of searching online and speaking to friends, I was referred over to Dr. Lee at Zin Dental. I could tell I made the right call as soon as I stepped into the office. The lady up front was extremely comforting and sincere in getting me set up in their system, even giving me extra goodies for my daughter, which totally helped in distracting her enough while she was waiting for me. As soon as Dr. Lee called in me, he was very thorough in explaining everything he was doing and presenting what my options were moving forward. The best part about this visit was that he was extremely genuine in his advice. He didn't try to sell me on unnecessary procedures, in fact he kept offering options that would be less invasive (cheaper) because his philosophy is to preserve the integrity of your natural teeth. All in all, I'm not one to rave about a dentist visit (who is??), but my visit with Dr. Lee was definitely above and beyond all my expectations. I'd highly recommend Zin Dental, especially with Dr. Lee. read more

It's a really nice clean place,that's a reason make me write down a review,and also dr Lee really friendly good hand skill! Special the surgery room,they use the special papers sterilize and wrap everything in the surgery,is the best place to do implant' read more

So I don't usually leave reviews but I had to for this one. I'm new to the area so I had to do a lot of asking around to find a dentist I can trust, and Dr. Lee was definitely worth the research. The staff is very friendly and caring - I liked the general atmosphere in the clinic. Dr. Lee is a pleasant guy and you can tell he really cares about his patients. I had a few concerns going into the procedure but he made sure I had all questions answered so I felt comfortable with everything. So far, I'm very happy with both the visit and treatment.

Kind and caring staff and an excellent dentist! It's a clean and comforting atmosphere and Dr. Lee handled with grace and professionalism. What was amazing about this place was that Dr. Lee was not interested to see me back at his office. He was rather adamant about what I could do at home to avoid dental visits in the future. It just showed how he really cared about his patients rather than keeping his office more busy. read more

Every staff including Dr. Lee was so kind and professional! They know what they are doing, and the best part was the effort they put in to keep their space sanitized and clean. By far, this was my best dental office experience. read more

Zin Dentristry is awesome. Dr. Lee and Ms. June was very kind and patient centered. Dr. Lee's expertise was evident. My implants turned out great. Dr. Lee and Ms. June were so accommodating and informative of the entire process. I would highly recommend Zin Dentristry as one of the best, if not the best place for your dental work. They were very professional and Dr. Lee explained the entire process and his recommendations in details for my procedure. He teaches at UCLA on his off time and is very current with all the new procedures. Being a physician myself, I know the difference between good care and excellent care. Zin Dentristry gives EXCELLENT care! I would recommend Zin Dentristry to my family and friends as the best dental clinic I have experienced in my lifetime. read more

Great dentist! Dr. Lee is honest, friendly, explains procedures well, answers my questions thoroughly, and does great work. And he doesn't recommend unnecessary work, as so many other dentists seem to these days. The office staff is friendly and professional. Great experience! read more

Very clean the staff is nice and friendly. The dentists is the best he takes time explaining things and it's very knowledgeable

One of my life's most difficult challenges has been to find the best dentist for my mouth full of angry teeth and gums! Doctor Lee is now my knight in shining enamel. His staff and him were so helpful and clear, they made the hard work of getting an implant feel easy. Doctor Lee is very knowledgable and I love how nerdy and insightful he is about teeth. He has helped educate me a lot on how to better take care of my teeth and gums. My entire family including parents, aunts and uncles have switched here. We all drive from far away, but have to say it has been totally worth it. His equipment is updated, his prices are reasonable, his staff is kind, he is gentle and amazingly skilled. He definitely deserves a 5 star rating! read more

I went to Zin dental group and met Dr. Lee because I had so much pain in my lower back teeth. He told me it is because of cavity that overwhelmed the root of teeth. Kindly, he explained and showed me the exact condition of the teeth thorough multiple different types of X-ray. I have been visiting many dental offices in my life. I have never gotten such detailed information liked in Dr. Lee's office. Dr. Lee kindly explain which part of teeth is problem and why i need to get a root canal through evidences of X-ray pictures. In addition, manager come to me after examination to educate me how I can prevent this such big cavity and also about hygiene techniques. During the visiting in zin dental group, i enabled to learn importances of flossing, electronic brush, and water picks. Of course, perfect treatment with the root canal by Dr. Lee. Thank you. I like here so much. read more

I wanted update my review and add that now I have become Dr. Lee's happy client. Since I live in Koreatown, I wanted to find a dental office in LA. I was recommend a dental office by a good friend. During a regular checkup and cleaning, this dentist told me I need an implant. Since he doesn't do implants, he sent me off to find one with my open tooth! I began having an excruciating pain that lasted days without any medication because it was during the holidays (a long story). After this traumatic experience, I contacted Dr. Lee and they went above and beyond to accommodate and help me. Now, I'm in my last final stage of my first implant and it's been so great. So thankful I have a dentist who I can trust. read more

My 1st yelp review. When people say that, I thought to myself, who cares it's your 1st. Now I understand. You really want to get a shout out or for someone the opposite. Plus I didn't know how to set up Yelp account. At 1st I thought how does this dentist get a perfect score? There must be a catch or paid reviews. All the reviews about this place are totally 100% accurate, I couldn't believe it either. My 1st visit today, I needed 5 implants costing $17,000. But they recommend that I go elsewhere to have dentures made for a little over $1000, they don't do dentures here. Even though I wanted to try 1 implant instead of 5, they said I should see my denture option and can always come back and do the one. They did a full x-ray, Ms June (a sweetheart) spent so much time educating me. Not seeing a dentist for 30 years, Dr. Lee needed to invest more time for me. 30 years ago if I had a dentist like Dr. Lee, I would have never stopped going to a dentist. I was expecting to pay a $50 visit charge. Dr. Lee at the end didn't charge me the $50. For someone making minimum wage at a 24 hour convenience store, not charging me $50 equals to 3 hours of my work really helped me out. He didn't know how much I appreciated it and gratful. If this place allows monthly payments. I would have signed up on the spot. Thank you so much from the bottom of my heart to Dr. Lee and his staff. read more

I don't like seeing dentist. Who does!? But with Doctor Lee, I feel little more comfortable about seeing dentist now. You can tell he really cares about his patients, and he will not do unnecessary treatment. He explains every detail and answers all my questions very kindly and professionally. All equipments seemed very new and clean. Friendly and nice staff, and neat atmosphere are also plus. I am bringing my three years daughter in couple weeks. Hope she likes here too. read more

I rarely write reviews, mainly because it is really hard finding a place where they truly deserve it. Came to Dr. Sung Lee from a recommendation from my co-worker. The doctor was so nice and tender he took such good care of me that I came out so happy and grateful for that care they gave me, I had always been terrified of dentists because of past experiences but I am glad that there are good dentist out there that actually care about the needs of their patients such as the dentists from zin dental group.. Dr. Lee is honest, caring, and friendly. I consider him to be among the best in the nation - bar none. I highly recommend him. read more

I started coming to Dr. Lee's office for a several months now after I became not happy with my previous dentist who was very inconsiderate. Unlike my previous dentist, Dr. Lee is a very detailed and considerate dentist who definitely knows his skills. He truly cares about patients and takes extra time to make sure that issues are completely fixed. Not only that, all of his staffs are super friendly and well-trained. The hygienists are thorough but gets a job done quickly. I would HIGHLY RECOMMEND Dr. Lee to anyone who is looking for a dental practice and wouldn't consider any other options. read more

The best dental office and dentist ever. Super friendly and helpful receptionist. My daughter got her two of her wisdom tooth extracted with painless. Bravo!! read more

I changed my dentist to Dr. Lee a few months ago. After my first visit, all my family members now visit him for all sorts of dental problems. He is honest and reasonal and one of a few doctors whom you can trust. You know it is very hard to find one in these days. For instance, my previous dentist did not even had a CT scanner, an expensive device, and performed an implant surgery, which can be very risky. Dr. Lee has the CT scanner. He shares CT scans with his clients and consults and explains what needs to be done. Trust this review and visit him once. After that, you will find him no matter where you live. I personally drive over an hour in total to visit him. Peace out! read more

It is so difficult to find a dentist who really cares for his patients but Dr. Lee truly cares and his work is amazing! My family is very pleased with Dr. Lee and the entire staff at Zin Dental Group. They are all so friendly and kind. read more
