Dr. John and his staff are always very nice and I feel well taken care of here. My husband and I have been coming here for a year now and have had a great experience. read more

I had a great experience at this dental office. The staff were very friendly and welcoming, and Dr. Tchaboukian was professional and patient. They took the time to explain everything clearly and made sure I was comfortable during the whole visit. The office is clean and well organized. I highly recommend this place to anyone looking for a trustworthy dentist. read more

I've been going to Diamond Bar Dental/ Dr. John for a few years now. He really cares about his patients and helping them have the best dental health. Maria, the new front desk staff person, is very friendly and helpful as are the assistants and technicians. I enjoy coming here (as much as one can enjoy going to the dentist ) for the quality care and friendly staff. read more

Dr. John Tchaboukian continues to prove, time and time again, that he is the best dentist I have ever known. His professionalism, expertise, and technique are truly unmatched. Every visit reminds me how lucky I am to be in the care of someone so meticulous and committed to perfection. I'll never forget the experience I had with a previous dentist after getting six veneers -- I left their office in tears, overwhelmed by pain and frustration. In stark contrast, today Dr. Tchaboukian prepped eight of my bottom teeth, and I left feeling perfectly fine. Yes, it took a couple of hours, but every minute was worth it knowing that I was in the best hands and that the end result would be nothing short of exceptional. Dr. Tchaboukian's attention to detail, gentle approach, and calming presence make even the most complex procedures feel comfortable and manageable. He is a true artist and a compassionate professional, and I'm beyond grateful to be his patient. If you're looking for someone who genuinely cares and delivers consistently flawless work, look no further. read more

I am beyond grateful and pleased with the dental work Dr. John Tchaboukian at Diamond Bar Dental has done so far. Let me tell you I came in desperately after letting issues with my teeth go for far too long. I was trying my best to manage it on my own, but to no avail. I have big time anxiety when it comes to having dental procedures. Doctor is extremely patient and explains everything with precise detail, which I appreciate because he is not only showing you what needs to be done in real time, he is also educating you on your own mouth structure. He and his staff have such a welcoming and gentle bedside manner without judgment, which is all the more comforting. So far I've had two bone graphs, a wisdom tooth pull, and eight cavities filled. I am awaiting my next appointment to have two crowns placed, and hopefully with the long term goal of getting Invisalign to straighten out my bottom teeth that became impacted over time. Prices are fair especially considering the expertise and meticulousness you're receiving at Diamond Bar Dental. I would 100% recommend them to my family and friends. I feel quite fortunate and blessed to have found such a wonderful group of professionals to trust with my dental needs. Thank you Dr. Tchaboukian and staff for helping me feel more confident about my mouth again. read more

I highly recommend this dentist. They are very clean and friendly and professional. I will be coming back and I'm happy I found them.

Great experience and professionals. Awesome doctors and nice facility. Will definitely comeback every 6 months for our usual cleaning

Getting my crown put in. And getting my implant tooth installed. Love how kind and patient they are with me. I do miss Jerry Young cause he was always jovial. I love our new dentist all up on. Newest and best new procedures. And great sense of humor. Never been happier. With this transition. read more

This dental office is the best I've ever been to. The front staff is super nice and the Dentist Dr. John is an expert, caring and takes his time extremely professional. The dental hygienist Samantha did my deep cleaning and was a very pleasant experience. She works from her heart, listens and makes sure you're okay throughout the whole cleaning. They accommodated me for my health problems and made sure I was okay 100% of the time. Such a wonderful place I'll never go anywhere else! 5/5 ! read more

If I could give negative stars, I would. I don't normally write reviews, but I believe every potential patient deserves to know what they're coming into. I was genuinely horrified by my experience at Diamond Bar Dental. Let me explain why. I went to see Dr. John Tchaboukian for the first time for a checkup. He appeared very professional and did a quick checkup, looking around and taking pictures of my teeth to show me. In the end, he diagnosed me with 12 FILLINGS AND A CROWN! He gave me convincing reasons and showed me parts of my teeth (discoloring and natural grooves) that supported his diagnosis, before telling me he was busy and moving to another patient. I was thoroughly convinced at the time that I had horrible mouth hygiene. The hygienist came in soon after and was very friendly. She periocharted my gums and explained things throughout the process. After checking my gums, she said she felt a lot of tartar buildup and that I would need a deep cleaning. Again, I had no reason to doubt anything I was being told because the staff was super convincing in their explanations and addressed potential concerns. After the diagnosis, I made my way out. The lady at the front desk showed me the crowns they used and told me they were made of "top-quality porcelain." I listened and then requested if it was possible to receive a copy of the pictures they took of my teeth. She said yes, but it would be a charge of $15. I agreed and paid, only to receive small and grainy images. I asked if they could also email me the images, but she said that wasn't possible. Fast forward two months, I've gone to two other dental practices to get their opinion on my teeth. Both of them said that my teeth are extremely clean and cavity-free. They were shocked after I mentioned Diamond Bar Dental's diagnosis of my teeth and told me that I barely even needed a regular cleaning. After reflecting on this experience, I've realized that Diamond Bar Dental was only in it for the money. They diagnosed me with unnecessary and expensive treatments (which totaled well over $3000 for all the work they said was needed) and kept giving me false (but convincing) reasons why it was important. It's a scary world out there and I highly recommend getting a second or even third opinion when things seem off. Diamond Bar Dental's staff seem skilled and thorough (and I'm sure that they are), but they don't put the patient's well-being first and are only looking to make money off you. BE CAREFUL!!! read more

I Went in for a hole repair on my tooth. Happy with the results! The Doctor was able to fix and repair it to the point where it's not noticeable at all. Color and shape match all my other teeth perfectly. Can't even tell there was any corrections made. Great work. Happy with the results and quality of work. read more

The dental hygienist was really caring and careful while cleaning my teeth, and the front desk was very friendly especially Lesly and Monica

Was looking for a local dentist that I felt comfortable with and I'm glad I found Diamond Bar Dental! The girls in the front office were so friendly and Dr Fajardo and assistants were very gentle with my sensitive teeth during cleaning. I'll be back! read more

I have a completely irrational fear of the dentist to the extent of starting to cry as soon as I see the chair. I am so happy to have found this dentist! Everyone in the office from the time I walked in was so calm & welcoming that I was at ease. I had a deep cleaning & laser gum surgery done. I still can't believe how pleasant this experience was. I can honestly say they have a patient for life!!!! read more

I have been going to Diamond Bar Dental for over 20 years now and have always been treated with respect and almost like family. I am always satisfied with their service and great quality of dental work. If it's your first time looking into this place for some dental work, I highly recommend doing so. You'll definitely leave a happy customer! read more

I've had some pretty horrific dentist experiences, and this dental office is everything I could hope for in changing my opinion about the field. Literally everyone in that office is SO NICE. It's not fake either! They genuinely care, and you can feel it. Great place to go to, highly recommended, you won't regret it! read more

AWESOME dentistry. I avoided coming to the dentist because I suffer from tooth sensitivity. I decided to give Diamond Bar dental a try and have no regrets in doing so. The girls at the front desk were extremely welcoming and had me waiting no more than 5 minutes before they took me to the exam room. I was immediately greeted by Leann who immediately started the cleaning of my teeth. Leann was extremely friendly and was so patient in telling me what she was doing to my mouth (this kept me nice and calm). Once she finished with my cleaning, Dr. John T. Began to asses what could potentially be causing the sensitivity to my teeth. He found the cause and took care of the problem in less than 30 minutes. He was extremely professional and reassured me that I was in good hands. I had little to no pain during the procedure and couldn't have left happier. I highly recommend this dental office!

9/7/2017 Amazing dentists, dental assistants, dental hygienists, and office staff !!! I have been going to this dentist's office for the past 20 years.

I love a good dentist, they're hard to find! Dr John is a super guy and did some work that my last dentist said couldn't be done. The staff is super helpful and very friendly. I found them on Yelp and their reviews were good, they also take many insurances. I don't like going to the dentist, who does? I found Dr.. John to be caring and concerned with my pain level while he worked. I'm glad people use Yelp! I think you will be happy if you try DB Dental. read more

Everyone here is amazing. I had a wonderful experience with the front office, the wonderful gal who cleaned my teeth and great dentist! Everyone explains things thourougly & is more than helpful. I'm excited to say I finally found a dentist I can bring my family to as well. read more

Going to the dentist is generally a scary and uncomfortable task. Although still uncomfortable (lol) this entire office makes the process so much better. Every time my wife and I come in we are greeted with sincerity and offered coffee, water, snacks and conversation. The customer service is OUTSTANDING!!! Now on to the scary part... I had an bad gum infection, extensive tooth extraction, and bone graft from a root canal that my previous dentist performed. To add to everything, my teeth roots are on Incredible Hulk status. I kid you not, the next day I had almost no pain at all from the procedures. This office is so accommodating and professional it really blows me away. I recommend Diamond Bar Dental to everyone I know. Completely worth the drive from Rancho Cucamonga. read more

My girlfriend and I found this place online, and both of us were nervous going in because neither of us have been to a dentist in a while. The staff and doctor made us feel right at home, answering any questions or concerns we might have had. They seem to really care about our wellbeing, and tries to work with the clients as much as possible to get things done. Coming in during Covid-19 was a concern for us at well, but the office is always sparkly clean, and they have taken multiple measures to make us feel comfortable, even during this time. The staff are straightforward and clear on what dental treatments are recommended and why. The office is always decorated too depending on season/holiday. If you are looking for a dentist that's clean, fast, friendly, and will take care of you, Diamond Bar Dental is the place to go. read more

I have been coming to this dentist for years and Dr. John was referred to me after an incident with my teeth. Being that it was my first time meeting him and getting what seemed to me extreme work done; he made me feel comfortable throughout the entire process. He was very informative and listened to me whenever I had any discomfort. Since then my fear of going to the dentist has gone away almost completely. His assistants as well as the ladies up front are also extremely helpful and sweet as well! I would highly recommend this office! read more

Horrible experience! I paid $625 cash for a deep cleaning . I felt weird after it was done because it only took about 40 minutes. 3 weeks later I visited another dentist who said : you need to clean your tooth because it seems you haven't cleaned your tooth in 6 months.. Also, I have a $40 cancellation balance in my account, when I request my medical records, the working staff said they give my medical records only after I pay the balance. Feeling very bad about their service read more

The best dental services. They make you feel like family. Great on explaining everything they are doing.

This place is fantastic very thorough clean professional & best of all affordable I recommend all of my friends and family for any kind of dental work from cleanings to tooth extractions ! read more

A+ for Diamond Bar Dental! read more

Lauren is the reason I'm making an appointment. She's amazing at what she does. -Sancheezy

My review is specifically for Leann Stepp, the RDH (registered dental hygienist). She did an amazing job and she seemed genuinely pleased to do her job and she also actually cared about how much I know about cleaning my teeth and how they felt. She gladly explained anything I asked about and more. I use to have braces, I got them off about 5 years ago. There has always been a piece of cement on my front tooth and no one has ever taken it off, I had asked a few times before but gave up. She saw it and asked if I had braces and she scraped it right off, I didn't even ask. Now it feels like I have a brand new tooth haha. All in all she was really thorough. She cleaned my gums like nobody else has before. Note that this was the first HYGIENIST I've ever seen. I don't know what the others I've been seeing for the last five years are, but she did the best job. Thank you! read more

Dr. John Tchaboukian, Leann Stepp and the whole office. I want to thank all of you. I came to you for a 2nd opinion and you answered all my questions, took the time to explain my treatment and took care of my dental issues with the least invasive treatment and the most caring and friendly atmosphere. I would recommend this dental office to everybody. I am very greatful. Thank you again. read more

The staff here has always been wonderful. My family and I have been coming here for years with Dr. Fajardo and we love it here. She has always done a great job and wants only the best for you. I met Leann and John for the first time and am truly excited to see what's in store from them because they as well seem wonderful! Especially Leann I absolutely love her already from how cautious and concerned she is with your teeth. I have a lot of work to be done STILL and I wouldn't go anywhere else. Absolutely love you guys thank you for all the warm love and care. Especially the ladies up front, you guys are always all smiles. read more

Dr. Fajardo is a great dentist. We have been going to her for years. They have changed their billing procedures, which is fine but being a patient after all these years you should let people know while booking the appointment that the billing process has changed. Not 7 1/2 months later when you send a bill stating we are 90 days late and threaten to send me to collections. I have never been late on any payment or bill in my life. You just lost 5 loyal patients over $38 read more

Been going here since I was a kid. My family and I Love this place. Great staff always. Call and ask to speak to Lauren or Whitney. Check it out read more
