PATIENT REVIEWS

I’ve been a patient at Optimal Dental Center for over a decade and have been consistently satisfied with my dental care. They have shared ideas for better oral hygiene, caught cracks in teeth before I knew they were there, replaced crowns and more. I have never had to wait more than a few minutes for my appointment and the waiting room, recently remodeled, is always clean and pleasant. I have nothing but nice things to say about the support staff as well. Thanks Optimal Dental for making it easy for me to maintain good oral hygiene!

Extremely happy with this dentist and the entire staff! Their VP and program director is incredibly helpful and patient!!! Really generous with her time and information. They worked tirelessly with me and I greatly appreciate it! The dentist was very quick and efficient and didn’t hurt me even once during cleaning or in probing for what’s causing my molar pain. Not only do I highly recommend, but I already have my brother and sister-in-law going there. And my aunt is likely to follow. Very happy with them all.

Dr. Dang did such an amazing job with my sister’s braces! I decided to get braces elsewhere to avoid paying more and I completely regret it for the rest of my life! I ended up going back to Dr. Dang to fix my teeth after discontinuing with the other dentist. Definitely recommend them if you or other are looking to get braces, they will take good care of you!

Always a great experience at optimal dental center. they had system set up so everything was clean everyone was wearing a mask there was no one else in the office except for me then when I went in another person came in so we had social distancing. and of course the teeth cleaning and 6-month inspection of my teeth went quickly and efficiently. Dr Dang and the rest of the team are awesome

Karen Mayes (Fairfax office) is the best RDH I ever had. She very gentle and yet very detail carefully clean my teeth. She prompt me every step of the way that would make me very comfortable in the whole process. Best of all, she does not mind stop and allow me to respond with my comment and answer to her comment/question … Karen well deserve a 5 starts and 100% recommended. Thanks very much Karen (George Sat 11/7/15 10:40 am appt.)

Having lost my front teeth in an accident, and combating gum disease all my life, I am all too familiar with dentists’ offices; however, this office is the best I’ve ever patronized. They make you feel welcome from the moment you arrive. The costs are never a surprise, and they work with you to help you afford the treatment you need. They follow-up with you and listen to your requests. Everyone in their office is professional and make you as comfortable as possible. I highly recommend Optimal Dental Center.

Great service! I was impressed on how the staff of Optimal Dental Center (Fairfax) have taken all the necessary precautions given the current covid19 situation. Health screening questions were asked and gloves provided if you don’t have any during your appointment. My hygienist, Calvin Wallace, was extremely cautious. Similarly, Dr. Dang was very careful and showed positive attitude as always. The receptionists were welcoming with their warm approach which I felt (despite of their face masks) and practiced contact-less interactions. I have been their patient for over 10 years now and was so fortunate to have found them. Thank you so much Dr. Dang, Calvin, and the rest of the staff for your service; much appreciated specially during this extraordinary situation. Kudos!

I was anxious about heading back to my dentist for some necessary dental work, but, as always, the staff at Optimal Dental Center rose up to, and far exceeded, my expectations. As in the past, their professionalism, care and compassion were greatly appreciated. They provided me with a very through explanation of what to expect upon arrival which totally eased my anxiety. Once there, Carlos and Dr. Dang took care of me in every way, keeping me calm, reassuring me, and informing me of the progress of the procedure. I continue to be so impressed with this dental practice and cannot recommend them enough!

I had my teeth cleaned and I’m very satisfied with the service. First of all, the front desk staff were very courteous, friendly, warm and helpful. They made me feel welcomed and comfortable. Secondly, the hygenist, Karen, was superb. She was so thorough by telling me step by step the procedures she was performing. I really like her gentleness, always checking to make sure I was at ease. I could see that she was taking her time to carefully examine and clean my teeth. Optimal Dental has proven that their name “Optimal” has coupled with their performance. They have earned my trust and I will definitely come back.

I have been a patient at both Fairfax and Reston locations and have had an overall exceedingly pleasant experience at both. Starting from the friendly front desk greeting me and checking me out to the hygienists who are fantastic to the doctors & assistants. I have been treated by both Dr. Dang for my implants and Dr. Assadi for almost everything else on several occasions (root canals, extractions, crowns and fillings). I knew I needed a lot of work since I had work done overseas many many years ago so I did my research and so happy I found this office. These doctors really care and take the time to explain my treatment plan and options to me and what needs to be done first and how to go about it. It’s really hard these days to find such caring professionals that really enjoy doing what they do – it shows! They explain x-rays & take pictures to show in real time what is going on in my mouth. The offices are nice and Reston is new and beautiful with what seems to be the latest innovations. There are a ton of dentists in the area and I have tried quite a few but I feel super comfortable going to Dr. Dang and Dr. Assadi and in a strange way I look forward to it because of how friendly & accommodating the staff is, including the sweet assistants! If you want to know what’s going on in your mouth and get the right treatment, THIS IS THE BEST PLACE so look no farther! Thank you Optimal Dental Center!

Optimal dental is has such a great family and community environment. I’ve been going there since I was in high school and they have made me feel like I’m part of an amazing family. To begin with Dr. Dang is very understanding and accommodating. I was not responsible the first time around with braces and had to get them again. Dr. Dang made both experiences very comfortable and speedy. Pricing is very reasonable and always fair and adjusted well to every individuals specific situation. 100% recommended . The staff is very nice and always smiling , I will continue to go there for a very long time. 🙂

I had my first visit at optimal Clinic in 2012. I had read all the reviews and knew that they must have their act together. Yep, they do. I had a root canal and crown, with no pain during the procedure. I actually dozed off a few times. All around I am very pleased with the staff (Front desk / Dr. Dang, Dr. Calligan, and Dr. Nguyen) and price was just right for me. I strongly recommend for all.

Really had a great experience each time. Dr Dang was very gentle. I did not even notice that both teeth were out (extraction and bone crafting). I have to do two implants and many other work but going to the dentist hasn’t been so easy and a relaxing experience! I wish I had known the office a long time ago. To all seeking qualified and gentle hands, do not look further! Just book an apt.

Great customer service with a smile from the moment I walked in! Dr. Nguyen is efficient and explains things in detail! The dental assistant was funny and personable …… overall exceptional experience! Would recommend highly

My wife and I have been going to Optimal Dental Center for over 1 year. Thank you for your excellent service. The staff makes me feel very welcomed. I have never liked going to the dentist, but Carlos and Dr. Dang have had such good patience with me that I now feel very comfortable at the dentist. Congratulations on the new location in Reston; amazing technology and cool decorations. Thank you.

Dr Dang is one of the best dentist I have ever had in my 66 years of life. His work is outstanding and he is very careful courteous and thoughtful. I have had two implants and the results was perfect. I also never needed to take any pain medication because there was no pain. If you need a great dentist that provides exceptional service with very reasonable cost then this is your dentist. You won’t regret it

We’ve been going to this clinic for at least 5 years now even after moving out of Fairfax and lives 30 miles away. Dr. Dang is always very pleasant to talk to, super nice and down to earth. Maria at the front desk has always been very accommodating, always smiling and always gives you a warm welcome. There’s also a Dental Hygienist I can’t remember her name she’s asian & I know she has 2 lil girls. Makes you feel very comfortable, keeps you entertained with her stories and does an awesome job. Thank you, guys! -Marie and Angelo

First, I love the convenient location. Second, Optimal Dental Center leadership really makes a personalized effort to get your input and feedback, which I appreciate. For my appointment, I had Calvin as my hygienist and Dr. Dang as my dentist. Calvin was very gentle yet super thorough. He explained what he saw to both me and Dr. Dang and it was very easy to understand. Then Dr. Dang did my exam, and I LOVED HIM. I am a huge jaw/teeth grinder (who isn’t these days), and I have some spots on my teeth they need to watch. But instead of listing a litany of teeth that need crowns and thousands of dollars, he suggested a couple priority areas that I can totally deal with. He also suggested meditating before bed. I love the holistic approach and am not even dreading the visit for the crown I need to get.

Dr. Dang is wonderful! He is very dedicated and offers great patient care. He takes his time and explains always what he will be doing very thoroughly. The staff is very lovely, all very friendly. The results of my Invisalign treatment exceeded my expectations! The care provided by the entire team is absolutely exceptional!

I enjoyed my first time back to the dentist after a five year hiatus. Dr Nguyen was awesome. She was quick and gentle with my deep cleaning and cavity fill. The injection of Novocain had limited pain. All of the office staff was friendly and helpful. Dr Dang saw me for a consult on the day of my cleaning. I was impressed and felt comfortable there. Great Dentist office!

I was so satisfied with my hygienist, Kim, as well as the staff at Optimal Dental Center. They went beyond my expectations to perform a thorough and professional cleaning, especially during the Covid time. Thank you so much for always trying your best. I know I can always trust Optimal Dental for all my dental needs ♥️. Appreciated, Vanida Vilayvong

My highest recommendation to Dr. Dang, best dentist I have ever had. I’m terrible afraid of the dentist and he is sensitive and makes me feel calm and relax. He takes the time to explain every procedure and provide valuable advice. Also his staff is great they also take the time to get to know you and explain all your benefits. Love you guys see you soon!!!

ODC has always been a top notch dental practice! My family and I have been going here since 2006 and the reason why we keep going back outside of the excellent service, they treat everyone like you are a part of the family. That being said, the changes they have made to ensure you and your family are safe or at least to prevent the spread of COVID is on par with the guidelines.

If you don’t have a dentist or are looking for a new one- GO HERE!! I have been going to Optimal Dental Center for over four years and they are the BEST! So much so that I moved to DC and still drive out to the Fairfax location because they are that great. When I first went to ODC, my teeth were in bad shape. The staff helped map out a plan and detailed everything my insurance would cover and anything I’d be responsible for on my own. Maria has been an absolute blessing! When I switched jobs in the middle of getting an implant, she helped me manage the insurance switch overs so that it would minimize the out of pocket cost to me. She has always been incredibly friendly and I’m grateful for such wonderful customer service! Everyone has been so friendly. Dr. Dang and Dr. Nguyen have made me feel welcomed and comfortable every step of the way through my four years of dental transformation. Years ago I went to a terrible dentist who made me afraid to ever go to one again. The amazing staff at ODC has changed that and I can’t imagine going anywhere else. I’d give more stars if I could because they deserve it!

I went in Saturday for my 3 months cleaning since I’m not the best at flossing and getting those back teeth clean enough. Ozra was the hygienist who I had worked with once before and she was amazing as usual. She instantly had me relaxed and calm because even a cleaning is not easy for me to take. Within 40 minutes she has my teeth clean and ready for polish. I also learned that you cannot teach someone compassion it is something that comes from the heart and Ozra has plenty to go around. Even the office staff knows me well enough to always schedule me with a hygienist who I feel comfortable with. Ozra nice chatting with you and I will see you in a few months. I also got Dr. Nguyen to do my oral exam and that was a pleasure to see her smiling and beautiful face. I have said it many times that Dr. Nguyen is the most beautiful dentist I have ever seen. Even after 2 children she looks radiant and glowing every time I see her. Lastly I also got to see Dr. Dang and it speaks volumes to know that the commander even works the weekend shifts. Dr. Dang you have the best dental practice in the country and maybe the world.

SUSAN C. I have been treating here for several years. The dental work is excellent.  I’ve had surgery with stitches and implants too. They are so good and so gentle that you are physically comfortable through every procedure.  I don’t even feel the numbing shots being done.  I’ve had a lot of dental work over the years in different places. But here is the best of the best. The staff is incredibly nice. The financial office is incredibly good and works with you to make sure you optimize your health insurance and flexible spending accounts to your best advantage and gives you a bottom line figure of what your out of pocket will be so you both can plan your treatment to fit your own finances ahead of time. There are no surprises with costs or treatment. The costs are reasonable. The office and equipment are high end, the office is stylish and clean. The staff is outstanding and so welcoming. Every aspect of your experience is amazing. The quality of the dental work is way above anything I have ever experienced.

This is a great dental office that I have to write another review. They provide such a great service when accommodating my dental needs.  I feel very comfortable and trust their services.  Dr. Dang is very detail, gentle and patient.  Carlos and Katrina are supper nice, they make things gone so easily and smooth. I always talk highly about this office and recommend to all of my friends and family.

Excellent thorough clean service! The dental hygienist was great; she was gentle on the cleaning around gum line. Dr. Quyen was thorough in examining and explaining the state of my dental health. Most importantly the office was clean and followed strict guidelines of COVID-19. I was impressed on my first visit.

We’ve been with Dental Center for years. Haven’t come across any issue. As a full time working mother of 4, the front desk ladies has been so helpful with scheduling our appointments. Our 2 oldest had their braces, so therefore it is a requirement that we have to go for our monthly visit to the office. Their Dental Assistant (Carlos) is awesome, it is a quick in and out process. Our 2 youngest also attend their cleaning during the kids day session, took place twice a year. We don’t need to go to a separate pediatric dental. There are fun theme and treats for the little ones during their visit schedule on Kids Day.

My family and I moved to the area about 7 months ago, and immediately began searching for an orthodontist as my 11 year old son needed braces. We were incredibly fortunate that our first stop was Optimal Dental Center. Dr. Quyen Dang and his staff have far exceeded my family’s expectations. They genuinely care about their patients, and have treated my son with sensitivity and compassion. The hygienist Carlos always takes the time to explain procedures step by step and address my concerns. Dr. Dang has been able to accommodate my son when it comes to last minute appointment changes and unscheduled appointments. Dr. Dang was even available to us when my son experienced an emergency with his braces. That is absolutely more than any patient can ask for.  The front office staff is also incredibly professional and friendly every time I see them. You are not just another patient at Optimal Dental. You will always be treated with courtesy and respect. I highly recommend Optimal Dental!!

I enjoy coming to this dental office because everyone there makes me feel right at home and Dr Dang worked through the highest first, and discussed each next step and the options. As my dental health got better we discussed some less important or cosmetic options. At each point I thought I receive excellent service, reasonable cost, and much better health. Staffs are nice. Easy to make appointment/reschedule. Dentists have soft hands and good hand skills. I completely recommend Optimal Dental Care to everyone who is afraid of the dentist, afraid of the high cost but who would like for their fears to put at ease. Keep up the good work.

Dr.Dang is an excellent dentist. I, with my wife, have been as patients with optimal dental center for more than 10 years. Since we get ages so there have increasing problems for our teeths. The center takes care all of our dental problems and does a very good job. The persons of the team are very nice. They explain the approaches in detail first. Then they provide their best serves to us. We trust them very much.

My Review of Dr. Quyen Dang I have had such a remarkable experience with Optimal Dental Center. – The office is top notch, woah!!! super clean. – The wait time to be seen by the dentist was 5 – 7 minutes, which was considered ON TIME. I was so impressed. This is based on my 3 visits so far. – Administrative Staff: very helpful, courtetous and friendly. – Dentist & Hygienist: very thorough, detailed, super gentle, friendly and very professional. This office deserves a 100% satisfaction score and I would love to recommend Optimal Dental Center to all the people I know
