Going to the dentist is not my favorite activity, but it is a ‘must’ if you want to continue to have good health.  I had a long overdue appointment for checkup recently which revealed several problems.  If I must go to the dentist, Upland Laser Dental Center is the place I will go.  Staff, hygienist, dentist and her assistant are all calm and pleasant which makes ME calm. I have had no pain during the procedures and very minor tenderness after my cleaning etc.  I highly recommend this office.

Super friendly, I always feel at home. Experienced staff with up to date equipment. I also like that there is minimal wait time. The last dental office always had a long wait time and specialty dentist only came in on few days out of the month. With Upland Laser Dental there is zero to minimal wait time and Appointments aren’t extended based on specialties. Everything you need is already in-house

Let me tell you about this little gem of a dentist office. Everyone is very professional, but most importantly for me, they care about their patients. They break everything down for you…from any procedures you will have to do to how much money said work will cost you out of pocket (before hand).They make sure you don’t feel any pain – which is a plus plus for me. Stop reading these reviews and call them, already. Best decision you’ll ever make.

Couldn’t ask for a better dental office!  Friendly staff, efficient service and a relaxing view while getting your dental work done!  I was really impressed that they were able to do my cleanings and 2 cavity fillings at my first visit.  Most places would make you come back several times. The laser used to do my filings was painless and there wasn’t even any numbing needed!  I would HIGHLY recommend this office, especially if you have had a bad experience at the dentist in the past.  It’s a little out of the way for me but SO worth the drive from San Bernardino!

I had to cancel two appointments before they fit me in with little notice today. From the moment I walked in everyone made me feel welcome and in good hands. All the staff are very knowledgeable and they listened to me. They even adjusted my treatment based on my suggestion. The Dr. Is confident and capable putting my comfort first. The procedure was painless and surprisingly quick. They have earned my business and will use them for all my dental needs.

Because of the friendly staff and very professional employees that do outstanding work , I’m no longer afraid to go to the dentist. Thank you Upland laser Dental

Aida G. from Orange County, CA (Source: Yelp)


I don’t know where to begin! The staff is friendly, knowledgeable, and patient. The facility is clean, modern, and welcoming. If you are like me and have had unpleasant experiences in the past I HIGHLY recommend coming to Upland Laser Dental Center. The hygienist was great and changed my perspective and taught me so much about everyday oral hygiene. My husband has his appointment next week!

I’ve been a patient for many years. I can’t say enough of how well the staff and Dr. Nguyen take care of my family. They always go above and beyond. They are always improving their practice and ensuring they provide the latest and greatest dental advancements, techniques and equipment. Thank you!

Sean C. from Alhambra, CA (Source: Yelp)


Upland Laser Dental Center is not your typical dentistry. I have been going here for almost 10 years and have seen that the staff take pride in making your trip the the dentist as satisfying as possible.Dr. Nguyen is even licensed to treat sleep apnea and do invisalign. Staff are super friendly and helpful. They focus on treating  your concerns and only make necessary recommendations. You will find that the office is cozy and professional. The team always looks for ways to improve patient experience, incorporating the latest advancements in technology, from wireless equipment, movies, and touch pads to nifty shades and raffled prizes. I highly recommend this place for anyone looking for a good, family dentist. You won’t be disappointed.

Steven V. from Fontana, CA (Source: Yelp)


Amazing experience here at this office. The staff is super friendly and makes you feel right at home as soon as you walk in. The dentist were very patient (because I’m one of those people who are scared of the dentist) made  feel comfortable. And have a overall good experience highly recommend this place

Hector G. from Ontario, CA (Source: Yelp)


This dentist is amazing!!! I haven’t been to the dentist in years because of problems with three past dentist not numbing my mouth properly and causing severe pain while working on me not Dr. Nguyen, he got it right the first time! The icing on the cake is that he doesn’t use shots. He has this cool device that massages your gums while administering anaesthetic. I had a severely decayed tooth pulled and replaced with a dental implant. I had zero pain during the pulling of the tooth, zero pain during the installment of the implant screw, zero pain after the surgery, and not one drop of blood was lost due to the state of the art laser. I’m forever thankful to Dr. Nguyen!

Upland laser dental is the best, I’ve been coming here for the last 10 years and my teeth are healthy and strong, Dr Nguyen is very patient pleasant to deal with and his technique is unique, no pain no extra dealings . I recommended many of my relatives and they all are very satisfied . I recommend this center to every body . You’ll be very surprised and please with each treatment,

After visiting Dr. Nguyen a couple more times, I feel comfortable saying that he is a great dentist! So accommodating and very friendly and comforting for dentist-fearing patients. I did a deep cleaning and I was just expecting to be staring at their faces the whole time, but they had this SUPER cool device that lets you watch a movie through these special goggles while they clean your chompers. I watched Book of El (they had a number of different movies.. kids movies, kid tv shows.. and Sex and The City LMAO. Crap.) They finished all the procedures within 45-60 minutes. I almost asked them to just let me finish the movie. Who wants to go to back to work when I could be watching Denzel chopping peoples heads off?! Anyway, the deep cleaning was great, my mouth felt like a sterile operating table. Also, Dr. Nguyen gave me a LIFE CHANGING (simple) procedure. I’ve always had these white spots on my front teeth, ever since I’ve had teeth. He said the spots were calcium build up, something you’re just born with (well, when teeth grow out).  The very first visit, he gave me that MI Paste to try to get rid of the spots. It didn’t work. Since then, this new technology came out where the dentist just wipes this liquid on (it smelled like super glue.. I hope it wasn’t) with this little brush, (tinier than nail polish brush) and lets it dry for 15 minutes. He was able to get rid of them. Don’t ask me what it was.. but it worked. After living my whole life with embarrassing spots on my front teeth.. they were GONE. I almost cried tears of joy when I looked in the mirror. Dr. Nguyen is so BUMPS. Update: Been asked about what the procedure was called. I called my dentist and confirmed it’s called Icon Filling Material. It’s a type of filling, no drilling, nothing too complicated. It’s a simple wipe on and wait to dry thing. It somehow penetrates deep inside the teeth, correcting the color. No bumps or weird texture on my teeth after. Btw, I did this procedure about 6 months ago. Still working great.

Wow!! I was so impressed what a great dental office, the staff is so professional and compassionate! Dr. Dat Nguyen is a great dentist very thorough felt really comfortable with him. Usually I’m very nervous and scared Dr. Dat Nguyen and his staff put at ease. Everyone in this office is so nice …. I wish I would have found this dentist office sooner!!!!

Kumar G. from Granada Hills, CA (Source: Yelp)


Dr. Nguyen is an exceptional professional.I had the laser treatment for snoring 2 months ago.I have to say it WORKS!!!!!!!! my Gf and I can sleep in the same bed ALL NIGHT!!!!
Thank you Dr. Nguyen.Ps.  The doc is awesome, very cordial, friendly and sensitive to your needs.Sincerely Kumar Gulrajani

Christopher K. from June Lake, CA (Source: Yelp)


I have had “issues” with going to a dentist since childhood, and I am now retired.  It had been approximately 14 years since I last visited a dentist, but some increasing tooth pain forced me to find and visit a dentist.I consider myself extremely fortunate to have found Dr Nguyen.  When I called to make my initial appointment, I explained my discomfort with visiting dentists and that I was very apprehensive.  The staff listened to my concerns and assured me that I would be treated compassionately.  Upon my first visit, and first meeting Dr Nguyen, I again expressed my anxieties and concerns.  Dr Nguyen patiently listened to my litany of past bad experiences, and assured me that I would not have any discomfort.I have been a patient of Dr Nguyen’s now for over four years.  He is the first dentist where I have felt so comfortable that I gladly make my regular dental check-ups and follow-ups.  I have had several different dental procedures, including a root canal, and have not experienced any discomfort. Dr Dat Nguyen is truly a compassionate, concerned and caring dentist.  I whole heartedly recommend his services to all my family and friends.  It is also a positive that he is up to date with all the latest dental technology.

6 stars if I was allowed to give.. Best dental center ever. Best staff ever. Best dentist ever. Who can beat laser dental? No one! My kids love this place and never have to get shots. The crowns are amazing and fillings are super easy and quick. The cleanings are also phenomenal. Super clean. State of the art equipment. Smiling and friendly knowledgable staff. What more could you ask for in a dental center?

Jessica Torres (Source: Google)


Extremely welcoming , very clean and well organized. They make you feel so welcomed and they are helpful and kind people. Would recommend this place to anyone. It’s great Dental Center. I had questions they answered all of them with great detail and they assisted me when I needed it.

Yessenia G. from Rancho Cucamonga, CA (Source: Yelp)


They were so nice! Definitely going to get my Invisalign treatment done here. They even gave me a cute gift and answered all my questions. Thank you for your help! I will be back soon 🙂

Ashlee W. from Ontario, CA (Source: Yelp)


Awesome dentist!!!! Dr. Nguyen is the best!!! Virtually painless shots, great work and he is so informative. After wondering why my molars were in such terrible shape, even though I brush and floss, Dr Nguyen told me that sleep apnea can cause stomach acid to make its way up to your esophagus and into the oral cavity where it can ruin your teeth!!! I had no idea.  I also recently took my 5 year old to see Dr Nguyen as well, and he was so sweet with him. Explaining all the tools he would be using, and even demonstrating. Thank you Dr. Nguyen and team.

I’ve been going to this great facility for a little bit over 5 yrs. The atmosphere is great, customer service is great, and they always work with me on prices. They make it feel affordable, not like any other office when they hit you with number. The hygienist Paola is great, also Arlene always breaks everything down by detail. Last but not least Dr. Nguyen. Great Dentist, he really cares about his patients, I cant tell he loves what he does

Arlene Fernandez (Source: Google)


I’ve been a patient for over 5 years, even though I don’t look forward to going . The staff is very caring and make me feel comfortable. Paola is amazing my teeth always feel clean and sparkle. Thank you Upland Laser Dental Center

This place ROCKS!!! Super clean, kid friendly, customer service exceptional and the Doctor is AMAZING! Not only did they take care of my insecurity of being afraid of going to the doctor but his staff is sweet with great customer service. I’m keeping this Dentist till I have no teeth…lol

Di M. from Upland, CA (Source: Yelp)


Dr. Dat Nguyen….What a fantastic dentist! My daughter had an excruciatingly painful gum condition called pericoronitis on her back molar.
After seeing our regular Pediatric dentist she told us we should see Dr. Dat Nguyen to get this taken care of with his laser vs traditional scalpel surgery for quicker healing and reduced pain. To make a long story short, my daughter needed to have a good portion of her gum removed because it was obstructing the molar from fully erupting properly. Ouch! I called his office and his staff was amazing! They initially offered me appts the following day, then asked me if she was in a lot of pain. When I said yes, they immediately asked the dentist if he could squeeze her in the same day because they didn’t want her to suffer any longer. So we got in within 2 hours. They were fast and thorough in verifying my insurance coverage. I asked them to make certain it would be covered before we started any procedures. We arrived and the front desk staff was wonderful. They sat down and showed me the complete itemized breakdown of what costs would be so there were no surprises. I appreciated that immensely. There was virtually no wait and the dentist was so calm and gentle and very good about explaining what was going to happen, to reassure my daughter before doing anything. (Initially she was terrified).
Dr. Nguyen used a laser (Biolase) to remove the gum tissue as well as fix a cavity on the same molar that was covered by the gum tissue. All without any need novacaine! I couldn’t believe it! My daughter said it felt “weird” but didn’t hurt. Why did I not know about this laser and this dentist before? There was no downtime and recovery was quick and easy. No pain pills needed. That evening I got a call and text from Dr. Nguyen checking in to see how my daughter was recovering. Amazing skills and great bedside manner! My husband and I will be switching to Dr. Nguyen after this great experience.
Thank you to his entire office for taking such great care of my daughter!

Only yesterday, I visited Dr. Nguyen regarding treatment for severe sleep apnea.  Please allow me to state that I was more than impressed by his professionalism, knowledge, operating technique and his staff.  He takes the time to explain things fully and work with you to help gain the results you both want and need.  His staff is extremely kind, considerate and helpful. After a thorough consultation and breathing tests, I elected to undergo the first of three treatments to determine on my own if the laser technique actually worked.  Keep in mind, I have tried many procedures and treatments over the years with little success.  The next morning after being treated by Dr. Nguyen, I was simply amazed!  I don’t think I have slept this well for a very long time, and I am truly excited!  I look forward to improving my weight, blood pressure, and overall energy level.  For once, I see hope on the horizon and that is important.  My late father was a practicing dentist for nearly 40 years and I know a great deal about the profession of dentistry,  Dr. Nguyen is a fine clinician with whom my father would have been proud of his exceptional character.In terms of sleep apnea treatment, his approach is gradual, reasonable and very well thought out.  As an engineer, I performed my own research.  Before I met Dr. Nguyen, my ENT told me that I may have had to undergo extensive painful oral and throat surgery, with an extended recovery time, to improve my condition. I naturally hesitated.  The NightLase technique was like a dream come true.  There was no cutting, severe pain or recovery!  After Doctor explained it all, I was more than confident I was truly in the best of hands!  In the event, you require an oral appliance for OSA, Dr. Nguyen showed me models of the appliances he prescribes.  Without any doubt, they are simply the best I have ever seen!  Unlike many, they are lightweight, comfortable and fully adjustable.  Since the system is comprised of two separate pieces (upper and lower), they are designed so patients can speak and drink without difficulty.

They were great! Really nice, thorough, and actually cared about my concerns. Everyone from the moment I checked in, to the great Doctor, to check out exceeded my expectations! They are open on Saturdays and fit me in 2 days for an exam.

Casey L. from Upland, CA (Source: Yelp)


Dr. Nguyen and the staff are awesome. I went in for emergency dental work and I have a huge fear of the dentist, they were all great plus I got a text later in the evening to see how I was! I loved them so much I took my youngest son to see them for the first time and now he loves going to the dentist! The staff is very friendly and I highly recommend him to anyone that fears the dentist.

Great service & expirence! All the office members are great and took excellent care of me. Highly recommend! They were very friendly and helpful, they got me on a treatment plan and worked with my insurance seemlessly ! Was very impressed

Courtney Payan (Source: Google)


My son is very scared of the dentist and getting filling. The whole shot and drillong thing. Well since this office used the laser there was no pain and no shots. Also dr and assistant were amazing at helping him stay calm and explain what was going on. We have to go back for another filling but this time he should be ok to jump in the chair and zap the sigar bugs with the laser again

Alexandra M. from Rancho Cucamonga, CA (Source: Yelp)


I am no longer scared of the Dentist. . . Dat the Dentist is amazing, he isn’t shy when it comes to comfort and the amount of Novocaine needed to soothe the pain. The technology is amazing, and his staff are very friendly.  I love Dawn, she gives great advice when getting what you need at a reasonable price. I will be going here till my insurance expires and my teeth are as healthy as can be.  I highly recommend for single individuals to families with kids. Great promotions online for new patients.

Irma C. from Rancho Cucamonga, CA (Source: Yelp)


I was referred to Upland Smiles Dentistry by a friend, and I am so glad I took him up on the recommendation! Every time I visit I feel like they bend over backwards to ensure that I am comfortable and that I understand everything clearly.  They always go over the charges before any work is done, so that I know how much my insurance will cover and what I will owe (if anything at all), so there are NEVER any surprise bills. What I like best about Dr. Nguyen is he doesn’t try to sell you services that aren’t necessary. I have had dentists tell me (for over 16 years) that I need to have an ingrown molar removed. I’ve never experienced any of the multiple problems that those dentists have said would happen. Dr. Nguyen is the first dentist to tell me that removal is unnecessary unless I experience any problems or discomfort from it. I love his honesty. Another thing I love about the practice is that Dr. Nguyen uses all of the latest technology, most of it designed to make the patient comfortable and the work pain-free. I have never experienced painful visits and neither has my husband, who has had extensive work done. They also use technology to communicate about upcoming appointments, which is great for me and my husband (since we tend to be forgetful). You can sign up for email and text message reminders, along with the phone call reminder from his receptionist. Being a father of small children makes Dr. Nguyen a great pediatric dentist as well. We take our toddler to him and, although she flips out, he is able to effectively perform her routine check-ups. We have taken her there since around her 1st birthday. I cannot say enough great things about Dr. Nguyen and his very friendly and professional office staff.

I have been a patient here for a few years. Arlene , Dr. Nguyen and Paula are great. And staff. I highly recommend this office. Very clean with updated equipment. Paula is very thorough with cleaning teeth. I even have my kids going to them now.

Tricia Barron (Source: Google)


The staff and dentists here are amazing!! Very friendly, they take the time to discuss procedures and answer any questions you have. Both my 7 year old son and I have had to have a lot of work done on our teeth, and both experienced NO pain from shots or work done because of special lasers they use! I highly recommend Upland Lader Dental Center for ALL members of your family!
