Always upfront and honest about my oral health to insure your getting the best out of your money you can tell THIS DOCTOR REAL CARES!!!! About all his patients! read more

Best dentist office experience I've ever had. The care is excellent. Staff is friendly and Dr. Nguyen is so patient and thorough.

Dr Nguyen along with Nick took me in during these tough times (04/02/2020) Pandemic. I broke my tooth and called and left a message. Within minutes Nick called me back and made me an appointment he following day. From when I arrived to sitting in the chair, they made me feel comfortable. What was amazing is that they went to work right away and saved my tooth as well as did the cap in house. Truly remarkable to see how advanced Dr Nguyen is along with his staff. Never ever I have seen such technology first hand. Custom Smile Dentistry will be my dentist for life and I thank you from the bottom of my heart for taking care of me during these rough times. read more

WARNING. There are plenty of other dentists in the area which are more kind, compassionate, and competent. No need to go here. This dentist is unethical, unprofessional, uncaring, and incompetent. And frankly, this person displays many of the same characteristics as other people I know who have Narcissistic Personality Disorder. This dentist is unethical, because he charged me for a follow-up procedure to fix his own work. Hid did the crown. The bite was off. He charged me to fix it. What that means is there is no guarantee of the quality of his work. What an astonishingly greedy and unethical thing to do to charge someone who is simply seeking relief from a medical procedure that you are responsible for performing competently. Granted, I went back five times to get my crown adjusted, but that leads me into the next point. This dentist is incompetent, because what kind of dentist needs five visits to fix a bite? Plus, he told me he intentionally adjusted my bite in the original procedure but then for some reason refused to believe me afterwards when I told him the bite was off. It's like he couldn't be wrong. Why would I lie about the bite being off? The evidence supporting the fact that the bite was off is the fact I went to another dentist, who didn't argue with me but who cooperated with me, who did adjust the bite and now the problem is fixed. You can only be incompetent if the patient sees you five times for the same thing and you still don't fix it. This dentist is uncaring, because he has no capacity to feel empathy. He doesn't care about you, and he doesn't care if you are in discomfort. Each time in five visits I went in to fix the same procedure he acted put-off. He actually blamed me. For what? I don't know, but I certainly knew it was not my fault that the bite was high. He only cares about being right, not about the patient. His actions have a clear message: visiting him is inconvenient. So take note people, he doesn't care about you. This dentist is unprofessional, because he doesn't listen, he doesn't display a caring demeanor, he doesn't guarantee his work and he is not concerned at all about the quality of your experience. You don't receive compassionate care here as you would expect and want from a medical professional. It's not professional if, when you have made an error, you can't accept responsibility and fix it. Finally, I don't understand how any good person could work in this office and continue to be a part of this unethical business. You knowingly charge people who are simply seeking relief from a procedure done in your office? As if we are abusing your services and you must punish us to come in? Wow. How do you sleep at night? If being a party to taking advantage of people while they are in your care is okay with you then you have greater problems than poor reviews on social media. [I have even gone so far as to report this dentist to the appropriate city, county and state officials, as well as several professional organizations outlining in detail how unprofessional, incompetent and unethical this establishment is. My commentary was welcomed.] read more

I love my dentist!! I moved to Laguna Beach and still make the trek to see Dr. Nguyen! I actually chipped a tooth, and he was able to see me the next day. This is a really special office with fabulous customer service and technology! Everyone here is also very gentle - I've never had a bad experience! If you're looking for a new dentist, look no further! read more

My new favorite dentist office in the entire world! I haven't seen a dentist in a little bit and thought it's more than time to at least get a thorough cleaning in; also already thinking I might have a cavity... From my first contact with the office on the phone, to the time I walked in, through the entire treatment, until I stepped out of the door - everybody was so nice. The atmosphere was calm and positive. I got the cleaning right away (which was not painful whatsoever!) and will have to get 2 cavities taken care of. Nothing was pushed upon me; I never felt pressured. Dr Nguyen basically showed me "some issues" and gave me options (from cheap over medium to expensive) with all the pros and cons. For a vein person like me: those issues ARE REAL and worth a thorough consideration. Overall, a very professional, positive and pain free experience. read more

This is way over due, but I love this office! I've been coming here for a couple of years now and there's no other dental office I want to go to. Previously I've had dentists tell me my teeth were going to fall out if I didn't have all these procedures and I've had numerous gum surgeries, but after seeing Dr. Nguyen I finally feel I am in honest hands. I've received such amazing treatment by the whole staff. I would highly recommend them to anyone! read more

Very warm and friendly environment from office receptionist to Dental assistant. They return calls promptly. I also appreciated the dentist's patience on dental education accompanied with the advanced technology provided in the office. read more

If I can take off that one star or go minus star, I would do it happily. The clinic is clean the staff are good and kind, but dr Nguyen, is a MONEY SUCKER! Watch out, he would create problems in your mouth just to charge you money! He is a general dentist, Yet, he convinced me that he can do a root canal BUT first he needs to make a 3D imaging for the tooth, when I already had a tons of X-Rays. He insisted to see the 3D image so he charged me $250 for the image, then I ended up going to a root canal specialist. When I told the root canal specialist about the 3D image she was shocked to hear that! That's when I knew he created those loops to make more money! When he could have just referred me to a specialist instead and save me that 3D image cost. My advice to you all is avoid dealing with Dr Nguyen you will go bankruptcy in a short period of a time. He won't cooperate with the patient, instead he will tell lies to convince you to have more procedures, x-rays, 3D images, unfortunately all for his own benefit just to steal your money! I'm done dealing with them! Minus zero to dr Nguyen read more

I've never had a dentist office so amazing. Everyone is super friendly and accommodating. The woman who runs the front office found out I had a before and would text me about appointments so that I could multitask without waking baby. The assistant, dentist and hygienist were all friendly and very informative about everything they were doing. read more

Excellent services with friendly staffs. Dr. Nguyen is a great dentist who I had for years. I still go to him even after he had moved an hour away from where I live. He's the best one out of all the dentist I've gone to ; and I had gone to many... read more

Very efficient office filled with very kind people from the first contact and including the Dentist. They were on top of everything to make sure my appt ran smoothly ( incl. my insurance ) they have the very latest in technology - to refine their diagnosis which allows for the very best service and outcome which is so appreciated, you only have one set of original teeth! This is a compliment- the reception area was completely nice but you didn't feel like they unwisely overspent to make it ultra chic. I hate looking for a new dentist- but moved and had to. I'd definitely recommend to save yourself some grief- just go here‍ read more

I just switched to this dentist and I'm glad I did. Thanks to Dr. Nguyen and his friendly and caring staff for their work. My teeth are feeling better than they have in a long time. read more

Is it normal to look forward to a visit to your dentist?? I actually do! They are absolutely the best possible dental experience one could hope for and more. Professional, ultra-competent, up-to-date on method and tech, friendly and concerned for the comfort of the patient in every way. I cannot come up with enough superlatives for Dr. Nguyen and his staff. They are all aces!! read more

Friendly staff and gentle, expert care by Dr. Nguyen.

I was having extreme pain from a bad wisdom tooth. My current insurance no longer took my original dentist so I had to find someone new and fast. I found Dentist Ngyuen and looked at the reviews and decided to give him a shot. Well I was able to get a same day appointment not only that they extracted the tooth that same day too!!! Dr. Ngyuen was great at putting me at ease. I had been dreading taking out my wisdom teeth out that I procrastinated until I could no longer bare it. He made this experience a walk in the park. I came out with minimal pain and swelling and was able to go back to work the next day. His staff was friendly, professional and quick. I am so happy I found Custom Smile Dentistry! read more

Once again amazing office visit. Highly skilled Doctor. Extremely professional staff. Always feel like a welcomed part of the family. Very relaxing atmosphere. read more

I have nothing but great things to say about the experience at Custom Smile Dentistry. Our visit from start to finish was top notch and I could not have asked for anything more. The staff was super friendly and we were greeted and taken care of by Ernesto as soon as we walked in the door. The office was nice and clean and Dr. Nguyen is as kind and as professional as they come. He was very straight forward and direct with orthodontic treatments and options and made us feel extremely comfortable the entire time. We will definitely be returning in the future as soon as my little one loses all of her baby teeth. Thank you Dr. Nguyen and the Custom Smile Dentistry staff! read more

In all of my interactions with the staff of Custom Smile Dentistry, I've found them to be extremely professional and friendly. Highly recommended. read more

Moved to Sierra Madre a few months ago and needed a new dentist. Dr. Nguyen and his staff have been amazing! They put so much time and care during cleanings and exams. Very thorough! My 5 year old felt so comfortable with them all! Great staff and hygenists! read more

I like their customer service. They open early to serve my needs and Dr. N. comes in to visit and check my teeth and gums. I would like to thank them for their hard work. read more

I was a patient of Dr. Yan for decades, and Dr. Nguyen is definitely a good dentist. I have no complaints about the treatments I have received from him. My problem is with the general attitude of the office. Since Dr. Nguyen took over, at every visit the staff has tried to sell me something extra, from ridiculously priced toothbrushes to treatments. But my experience this week did me in. I had an appointment on Tuesday afternoon but woke up very ill that morning with what turned out to be a severe respiratory infection. I could barely function. I called the office early to cancel. The woman on the phone tried to talk me into coming anyway, saying it would be OK because they wear masks and gloves. She obviously didn't care at all about my comfort (can you imagine someone working in your mouth when you're having difficulty breathing?) or about the other patients I would come in contact with and potentially infect. When I refused to come in, she quite huffily told me that there would be a cancellation fee. I no longer believe that the well-being of patients is the #1 priority of this office. Time to find a new dentist. read more

Everyone at this office has it together. I had some great dentists. I mistakenly thought they were all great and interchangeable. Then I moved to Sierra Madre and just picked a random dentist. Mistake. I went to a second dentist. Mistake. Either they messed up my insurance information, or they would have me waiting in the waiting room long after my appointment should have started, or had crazy hours that couldn't accommodate my work schedule, or were brusque, or took an insanely long time to just do a cleaning. But not this place. Their office manager does a great job of making the appointments and dealing with the insurance. She she sends email and text reminders. I always get seen within ten minutes (usually less) of my appointment time. I can always make an after work appointment. The dental hygienists are quick, thorough, and super friendly. I found Dr. Nguyen to be very friendly, clear, and available. This place just seems well run. read more

This is an excellent dental practice. Dr. Nguyen is very gentle with his treatments. I have had my extraction and implant surgery done here and the care is exceptional. Staff members Lauren and Ernesto are always helpful. Can be expensive without insurance but I highly recommend this practice. read more

I am a recently retired dentist that moved to Sierra Madre. I needed some repair work and thought that instead of driving an hour and a half to my former dentist, I would try a local & not to tell my background. I knew exactly what I needed. The " Custom Smile Dentistry" did everything exactly right. In fact, Dr. Nguyen was very meticulous and did an excellent job. No pain during the procedures and I had zero post-op discomfort. This is a great office. read more

I had seen Dr. Yan for three years and then have been seeing Dr. Nguyen for about three years now. Dr. Nguyen is a gentle, highly skilled, experienced, and organized dentist. He is kind and willing to listen and accommodate my needs. I am very happy with his treatment. I always feel pretty comfortable during treatments and never had any issues afterwards. His staffs are very professional and also kind. I strongly recommend him to anyone looking for high quality dental care. read more

Dr. Nguyen is the best, most compassionate dentist ever. He is as good as they get.

Dr. Nguyen did a great job replacing a crown for me. He also did my husband's crown and he was also very happy with the result.

Dr. Nguyen and his staff are the best. They answer questions fully, are as gentle as dentistry can be, thoughtful about your comfort throughout procedures, and endeavor to make the experience in the chair and in scheduling as simple, painless, and easy as possible. I have been coming here for at lest two decades, even back when Dr. Yan was the only dentist at this practice. Dr. Nguyen is an expert in the latest procedures, techniques, equipment, and materials. I have great confidence in him and his staff. read more

I have been a patient of Dr. Nguyen for more than a decade now. I have followed his practice from Chino to now in Sierra Madre. Dr. Nguyen is an excellent dentist. He is a good listener, and his calm demeanor is comforting and reassuring. His staff (Katie, Michele, Ernesto, Maria, and Adriana) are all great at what they do, very professional, yet warm and friendly as well. I recommend his practice all the time, and believe it or not, I'm not afraid of dentists anymore. read more

I have been coming to Dr.Nguyen practice for two years now and they offer excellent service. The office staff is very knowledgeable and understanding and make you feel comfortable immediately. Dr. Nguyen is thoughtful, friendly and meticulous. If work has to be done I want the precision of Dr. Nguyen's hands to do the work. By far, he's the best Dentist I've ever been too- read more

Custom Smile Dentistry is amazing!! I usually only write reviews for restaurants, however I really enjoyed coming to this office that I figured I should go online and give a Yelp review. Dr. Nguyen is so informative and educational he even taught me how to floss!!! Also his staff is super nice and helpful, you know how other offices the girls in the front are kinda mean and you feel bad asking them a question, well not this office his front staff made sure I remembered my appointment time, they even sent me a text to remind me. Since Im so forgetful and ask for them to give me a reminder call :) If you are looking for a dentist, give this office a call and make an appointment, you will actually like going to the Dentist. read more
