Check out what some of our happy patients are saying about us:

Monica U. from Placentia, CA (Source: Yelp)


I’ve referred my friends Dr. Dang’s way, and I don’t even refer them to my favorite restaurants. It’s the strangest thing to be so excited about a talented dentist. Dr. Dang is someone who actually cares about his patients and takes the time to discuss their needs with them. I’m able to be open and honest about my bad habits, and instead of shaming me or making me feel guilty about them, he encourages me to take better care of myself. I am, after all, only cheating myself when I don’t floss! He is incredibly conservative and honest in his diagnoses and procedural recommendations. He will always describe what he is doing, and why, and answers all of my questions in a way that I can understand the science behind his methodologies. He’s the kindest, smartest, gentlest, and most thorough dentist I’ve ever been to. He truly has a passion for what he does. Since I’ve been with him, I have actually started taking much better care of my teeth! My friends that I’ve referred his way absolutely raved about him. You can’t go wrong choosing Dr. Dang and Precision Dental. If you want to be somewhere you’ll be taken care of, THIS is the place to go!

Dr Dang is so thorough, gentle and kind. He takes time with each patient, explaining each step and informing you of what is happening next. The office staff is amazing too. Everyone is so friendly and ready to help. He treated our children, was very gracious with them, and even contacted us personally later to follow up on how they were doing. Would HIGHLY recommend him!

Renee T. from Newport Beach, CA (Source: Yelp)


Dr Dang got me in right away after I developed a severe toothache, seriously I was crying on my way in it hurt so bad! He was able to identify the problem right away and had me out of pain by that night! I was so scared to get any work done, so the idea of a root canal was really scary but he made me very comfortable! His staff are great too, they were so welcoming and helpful! I highly recommend Dr. Dang and will see him for all my future dental needs!

Excellent dental practice! I’m a physician myself so I appreciate an exceptional clinician when I see one. Dr. Dang took the time to do a thorough exam, did not oversell elective procedures, and showed utmost knowledge and care in developing a diagnosis and plan. The office featured minimal wait times, easy parking, and qualified staff. The front office had already run my insurance and developed quotes and pricing for future procedures before I even checked out! Highly recommend.

Dave R. from Garden Grove, CA (Source: Yelp)


Both Dr Dang and his staff are first class. My wife and I have had cleanings, fillings and crowns made by them and they do excellent work. They are very professional and caring people who always make us feel at ease. Highly recommended!

Wow! I really lucked out finding Dr. Dang and his staff! The dentist, Veronica, and Ann Marie were all amazing! Some of the nicest people I’ve met! Dr. Dang made me feel so comfortable and at ease. He was extremely knowledgeable (which I want in a dentist), and patient with me. So was his dental assistant. I would highly recommend him to anyone looking for a great dentist. The office was also very cute and clean! I’m really glad I found them!

Amanda N. from Garden Grove, CA (Source: Yelp)


(…) Dr. Dang’s office has all the components I look for in a dental office. Their entire staff is friendly, caring, and polite. It looks like they only hire the best and most experienced assistants and receptionists. I was able to book an appointment for a consultation the next day. They were able to accommodate my schedule before I had to leave for school. I never waited more than 5 minutes in the waiting room. They always finished my appointments in the time they said they would. I actually have some pretty severe dental anxiety and trauma from my childhood dentist. But after just 2 visits, my dental anxiety vanished, so much so I almost fell asleep on the chair! Thank you for the care you have given me.

Dr. Dang is amazing and we’re so thankful for the excellent care we’ve received! Beautiful and comfortable office. Dr. Dang is very thorough and communicative about what’s going on with your oral health. Great with kids, professional yet warm.

Jane Park (Source: Google)


Making appointments with this office has always been super easy and efficient. The staff is well trained, knowledgeable, and super kind. Dr. Dang is both very professional and easy to talk to. I was nervous about going in for a procedure today, but I’m pleased to say everything went really well due to the care I received. I would highly recommend this office!

Dr Dang and his staff are courteous, professional, and fun. What I appreciate most is how they won’t gouge you and try to upsell anything. Dr Dang is a conservative dentist and wants to retain your natural teeth as much as possible. While other dentists I’ve been to in the past seem to “find” decay left and right, Dr Dang only does the necessary. Nothing gets past him though! He caught a few areas of decay on my daughter that 2 other dentists missed. She is on her way to a fully healthy (decay free) mouth. Thank you Dr Dang!!!

Renz L. from Sacramento, CA (Source: Yelp)


Excellent dental practice!  I’m a physician myself so I appreciate an exceptional clinician when I see one. Dr. Dang took the time to do a thorough exam, did not oversell elective procedures, and showed utmost knowledge and care in developing a diagnosis and plan.  The office featured minimal wait times, easy parking, and qualified staff.  The front office had already run my insurance and developed quotes and pricing for future procedures before I even checked out!  Highly recommend.

We enjoy our visits to Dr. Dang for our routine dental cleaning and exams. The staff and Dr. Dang are kind, professional, honest, and approachable. Prior to Dr. Dang’s office, I had never had my teeth cleaned by a dental hygienist before and didn’t even know the difference that dental hygienists obtain degrees specifically for dental cleanings. I highly recommend Dr. Dang and his team of professionals. So glad we have a trustworthy dentist who takes awesome care of our pearly whites so we can continue to eat yummies easily.

Jennifer G. from Mission Viejo, CA (Source: Yelp)


I would wholeheartedly recommend this dentist. He is very kind, personable and professional. His exam and cleaning were careful and thorough and he took his time to explain everything he was going to do. His staff was also very warm and made me feel welcome and at ease, despite the fact that I was there for a filling. I definitely felt like I was in good hands at Dr. Dang’s office.

Steve E. (Source: Google)


Friendly and professional office staff and great hygienists and dental assistants. Dr. Dang is personable and friendly, but more importantly, he is honest, ethical, skilled at his profession, and takes the conservative approach first in treating dental issues. As a health professional myself, I highly recommend Precision Dental.

(…) Dr. Dang made new, removable retainers that also serve as night guards for me. They fit great and are impeccably strong! His office schedules appointments very well, and I was able to come in quickly once I realized it was time for a new retainer. Moreover, the environment has an atmosphere that is elegant, comfortable, and hospitable. Shout out to Veronica at the front desk who welcomed me so kindly and to Amanda who did a great job taking my impressions. Overall, I had a wonderful experience. I highly recommend visiting Dr. Dang’s office for any type of dental needs.

Dr Dang and all his hygienists are very qualified and professional in their work. I am very satisfied as a client happy to recommend to whoever wants their services.

Tiffany K. from Garden Grove, CA (Source: Yelp)


I never thought that I would ever be writing a good review for a dentist but this place is definitely worth the time. Throughout my life I’ve had terrible dental experiences and I was thinking that this place would be the same, but oh boy was I wrong. Dr. Dang and Amanda were both super kind and friendly. I didn’t feel judged and it was great to feel comfortable talking about my dental health. The images and information they provided me with helped me understand my teeth better and how to take care of my oral health. I am grateful to Dr. Dang and his skillful approach to addressing my dental health. My sincere recommendation and reference to all is to go visit Dr. Dang, my favorite dentist, if you have any dental issues. Also, they usually always give goodie bags filled with floss toothbrushes and etc.

Marcus D. from Spokane, WA (Source: Yelp)


(…) What makes Dr. Dang an excellent dentist is that he combines excellent dental skills with genuine care for his patients. On top of that, his staff follow his example exuding the same professionalism. As a family of five, we came to Dr. Dang after a referral from a friend. I assumed we would only need a routine cleaning. After x-rays and a thorough examination, we were informed one of our children needed a significant procedure. Not feeling comfortable to do it himself, Dr. Dang not only gave us recommendations for excellent oral surgeons, but he personally contacted them on our behalf. Like many, my wife and I have had some uncomfortable experiences in the past with dentists. Dr. Dang and his wonderful staff have extracted all anxieties!

Randy McGinley (Source: Facebook)


A good, knowledgeable dentist that is very accommodating and works well with his patient. Also need to mention his good sense of humor, easy to talk with on many different levels, making it easier to answer or explain any concerns that you may have. I can safely say that should there be any concerns or questions that you may have, can and will be answered by Dr. Dang in a timely manner that will give you, or a family member some peace of mind, surely for any questions that should arise!

Freddy G. from Garden Grove, CA (Source: Yelp)


Dr. Dang and his an entire team of professionals took great care of me in my visits to his office. From the moment you walk in through the door Crystal greets you with a pleasant smile and is very welcoming to the office. I had my deep cleaning with Xochitl today and she did an outstanding job at making sure I was comfortable throughout the entire process. Lastly, Dr. Dang thank you for having such a high level team in your practice and making patients like myself proud to refer friends and family to your office.

Richard Stamm (Source: Google)


As someone who is somewhat timid when visiting a dentist, this was by far the best experience I’ve ever had with an office. The office is very warm and welcoming, the hygienists are extremely nice, the dentist is very professional and the dental assistant is the greatest.

Mark C. from Trabuco, CA (Source: Yelp)


Sadly, I chipped a tooth last week.  Veronica was awesome and squeezed me in to see Dr. Dang on a day that they were super busy.  Dr. Dang made me feel like he had all the time in the world to see me.  He took the time to explain my options and think through the pros and cons of different treatments.  In the end, he was able to fill the tooth where it had chipped.  Now it’s smooth and perfect.  The whole procedure was fast and painless. The whole staff at Dr. Dang’s was super friendly and caring throughout my visit.  I had injured my back earlier in the week and they were very patient with me as I hobbled around their office. Thanks Dr. Dang.  I’ll be sending my whole family in to see you!!

Dr. Dang and his staff were all super friendly and professional throughout my visit. They really went above and beyond in taking care of my teeth; they even took into account my preferences in order to make sure that I was as comfortable as possible. I’m very thankful to have Dr. Dang as my dentist. I highly recommend him to anyone.

Stewart Fricke (Source: Google)


No fear going to my dentist. Gentle and accommodating. He will advise you what is necessary versus nice to do. No pressure, just motivation to take care of one of your best assets, your teeth!

Kari T. from Fullerton, CA (Source: Yelp)


(…) Dental work can be terrifying, even if you understand it well. Dr. Dang goes out of his way to ensure you are comfortable, that you understand what is happening and why, and also allows you to be a part of the decision-making process, rather than trying to force procedures on you that are unnecessary. He is a gentle hand, an intelligent mind, and a good soul who has all of his patient’s best interests at heart. If you’ve been putting it off and need a new dentist, this man is your go-to. 100%

Emily G. from Westminster, CA (Source: Yelp)


Dr. Dang and his staff were very attentive, patient, and easy to talk to. These are things I look for in a dentist as I tend to have anxiety when visiting the dentist. Dr. Dang really knows his stuff and was super nice and friendly. I don’t like going to the dentist but with Dr. Dang I feel at ease and comfortable!

Tal H. from Irvine, CA (Source: Yelp)


Dr. Dang was absolutely great. I usually dread going to the dentist, but Dr. Dang made the experience very easy going and relaxed. His staff was also fantastic as they were also extremely nice. Dr. Dang genuinely knows what he is doing, and will make sure you are treated well. He is understanding of what the patient’s wants are and weighs them to what needs to be done. He even checks up on how you are doing after you leave to make sure everything is going swell. Overall awesome experience. Best dentist I’ve ever had.

Brianne K. from Rancho Santa Margarita, CA (Source: Yelp)


Dr. Dang and his staff are knowledgeable, professional, and approachable. Dr. Dang has seen my whole family (including my five children) and we have nothing but great things to say about him! Dr. Dang is honest and kind – you can trust him! His office is very clean and his staff are so kind!

Pauline F. from Orange County, CA (Source: Yelp)


(…) Dr. Dang came in to examine my x-rays and look in my mouth. He explained what he saw and made some suggestions regarding my wisdom teeth. The thing I appreciate about Dr. Dang is that he’s really conservative in his recommendations for treatment. He’s going to keep an eye on a couple of areas, but he told me he’s not interested in doing unnecessary treatment, and I have a lot of respect for him because of that.
Afterward, Dr. Dang encouraged me to come back every six months for my routine exam and cleaning. I know this sounds funny, but I love the feeling of squeaky clean teeth and can’t wait to come back to get my teeth cleaned again!

Steven Lieu (Source: Google)


(…) They are worth 6 stars if I could give it! Dr. Dang walked me through the process of replacing a filling then explained step by step during the procedure on what to expect, I’m quite impressed with his professionalism and gentle approach. Thank you to everyone at Precision Dental OC for such a wonderful experience, I’ve already recommended your office to my wife and a few friends.

Brianne Kopp (Source: Facebook)


Dr. Dang was professional, courteous, and kind! He was gentle with our family and all seven of us would highly recommend him! The office staff is kind and easy to work with, and the office is clean and very professional. We are very thankful to have found Dr. Dang!

Dante Russomanno (Source: Google)


Dr. Dang and his staff are very knowledgeable and professional. They make you feel comfortable and give you the necessary information to make the best choice for your dental care. The office is clean and state of the art. I highly recommend.

Raquel Betancourt (Source: Google)


Dr. Dang and all the staff at Precision Dental are great. They are very welcoming and always have a smile to greet you. Dr. Dang will answer all your question with honesty and always making sure you get the best care. Thank you guys!!!

Christina T. from Bellevue, WA (Source: Yelp)


(…) Dr. Dang was so gentle!! One of the things I appreciated the most was the fact that right off the bat, he established with me a non-startling signal (raise/wave my left hand) to indicate to him that I was uncomfortable. Do you know why? Because usually there’s some tool, usually whirring, in my mouth when I’m uncomfortable and I don’t want to startle the dentist and have him accidentally do something worse! Also, he always gave me a head’s up whenever he was going to work on a new area of my mouth, what sensations to expect, etc.
The cherry on top was that I was able to close my eyes during the cleaning and actually relax. I mean, I almost fell asleep! I was tired from work but that’s gotta be saying something

John K. from Rockville, MD (Source: Yelp)


Dr. Dang got me in for an emergency and took great care of me! He is extremely thoughtful and professional in every way. His office has state of the art equipment and his staff is friendly and courteous. His treatment relieved the pain and I’m grateful for his kindness and expertise. This was my first visit to his office and I’m so glad I went to him for my dental needs.

While caring for the underserved and medically complex patients there, he became proficient at a myriad of dental procedures including molar root canals and surgical extractions. Upon completing his residency program, Dr. Dang stayed in Spokane, WA for a number of years, practicing dentistry and also serving as a part-time Clinical Professor at Eastern Washington University’s Dental Hygiene Department.
