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

Dae K. from Annandale, VA (Source: Yelp)


A dental office where I visit regularly for a check-up and cleaning asked me to visit a dental office more professional for root canal therapy because they thought one of my canines may need root canal therapy. I asked the Dr to treat my canine to cure it but said he is not professional for root canal therapy. So I got a mission to find out the best dental office in the area. I am a person very concerned with Covid-19 so I had to find out the dental office can respond Covid-19 very seriously and absolutely must be professional for root canal therapy because I didn’t want visit dental office much time but need to minimize visiting because as I told we are in a pandemic situation. I spent almost a month searching for a dental office that can fulfill my requirements as a customer who is very concerned about Covid-19. So now I have confidence I could leave a very strong review for here because now my tooth was cured and recovered well and very well functional and I do not get infected since I finished therapy two months ago. Let me share a little bit more detail below, Location: They are located center of Fairfax, VA so very easy and convenient to visit and have enough parking lots. From parking lots, very close to the main entrance door. In the same building, there are some other businesses located almost the same spot so a little gave me confusion to open the door for the dental office for the first time visiting but it is not really bother thing to me. Staff: They are enough nice, they are chill and provided instant response whenever I have a question. Good following up to make appointments. Dr.: Dr. Yoon. He did provide outstanding treatment to resolve my issue on the canine. Naver hurryed up during the treatment time but did everything he needs to do. very gentle. Respond COVID 19: They didn’t make appointments very tightly so I couldn’t get a chance to see other patients. Also while I was there, other clinic rooms were not operated, they only focused on me which is cool and makes me comfortable. They checked body temperature and all staff and Dr. wore masks and face shields to protect both parties. I could feel they tried the best to make comfortable their patients regarding Covid-19. They are highly recommendable and I will visit here again for other services I need to get in the future.

Having worked beside Dr. Yoon as an assistant I decided to have him do two elective cosmetic all- porcelain/zirconium crowns placed on my front lateral incisors. That was back in 2011( roughly). I am so happy with his work even all these years later….I’ve had dentists not even realize they were crowns until I ask for a xray of each one to check on any underlying decay. I am always complemented by dentists that admire his work and say ” wow, they’re some nice crowns”. Thanks Dr. Yoon and when I need them redone eventually, I hope you are still practicing!!!

I am a major denta-phobe. After waiting waaay too long to get things taken care of, I found myself needing lots of scary work. Ive been to several dentists in the area, and Dr Yoon and his staff are by far the best Ive found. Almost every single time Ive gone in, theyve been ready for me. The most Ive had to wait is probably 10 minutes max. Also, they call and remind you about every appointment, which I love because I forget everything. Dr. Yoon explained everything he did, reviewed all of my xrays, told me what to expect at every turn. He knew how nervous I was and treated me so kindly, never making me feel like a child or a wimp. His staff did the same. Im sure that after looking at my teeth, he coudve given me a 3 hour lecture about everything I was doing wrong, but never did. He is so- so-so thorough, using a super microscope when he removed decay, making sure that everything was gone and would never cause me problems again. I feel 100% confident that all of the work Ive had done there was done correctly and that I wont be going back for anything he missed. I have been there multiple times and wil continue to go back for all of my dental needs. I highly recommend Thomas Yoon Dental, especially if youre a total baby like me 🙂

Dr. Yoon and his staff are the best in the world. First, EVERYONE that works in the office are so professional and friendly. For someone who just started going back to the dentist on a regular, I’m so glad I picked this office. They are very knowledgeable at their jobs and honest at the same time. The staff makes you feel so comfortable and you really don’t have anything to worry about (you are in very good hands). Also, they work with your situation far as treatments and finances. If you are looking for a good dentist office, I would highly recommend Dr. Yoon’s Dental.

Johanna S. from Washington, DC (Source: Yelp)


Number one, I hate doctors. Number two, I hate dentists. Number three, I am afraid of sharp/pointy objects coming in my way… I have been going to Dr. Yoon for over two years now and I can’t say enough good things about this place. I love Dr. Yoon. I love his (new) dental hygienist, receptionist, and everyone else there. And because he is so patient, quick to listen, and super kind in explaining everything out to me… please disregard my number one and two! And he makes my number three not a problem… he is super gentle with my teeth and his patients! Okay, enough about complimenting my dentist… just go and experience it for yourselves 🙂

Tramaine G. from Fairfax, VA (Source: Yelp)


I love Dr. Yoon. He’s professional, personable, gentle, and educational, quick to offer kind advice on dental hygiene. And he’s always willing to make a referral to a specialist when necessary, unlike many general dentists who try to take on too much to earn a couple extra bucks. I can’t recommend him and his practice enough.

Since I met the staff I have had excellent experiences in this office. So good in fact that I recommended my husband, my sister and her son to this practice. My first impression was that I have never seen such diverse staff in this or any other county. They are all very competent and take their time to explain every procedure. They have the most affordable prices I have ever seen. I recently chipped two molars and the dreaded experience of getting fillings is no longer a source of fear. First, the Dental Assistant recommended that I kept my sunglasses on to avoid the irritating bright light on my eyes. Clever measure that no one had ever suggested before. I’ve had countless novocaine injections and they have never worked as well and as quickly. The Dentist Assistant maintained the water and suction on in perfect tandem with the Dentist’s movements. I never had the need to signal that I needed suction. Anyways, I have had only excellent experiences at this office.

Megs C. from Washington, DC (Source: Yelp)


Wow! I can’t believe we randomly stumbled on such a great dental office!! My husband HATES the dentist and made a point to tell them after the appointment that this was the best experience he had ever had at a dental office. It’s a very small operation, just three people but very efficiently-run. We didn’t wait more than 5 minutes to be seen and Dr. Yoon apologized for making us wait even that long stating that “he hated making an appt. and having to wait for it”. He is very down-to-earth and funny. He will tell you what you need to improve on without shaming you about it, he even admitted that he didn’t start flossing until he was in his 30s. He does his own cleaning, which is crazy…I’ve never had the dentist themselves do more than a quick run-by at the end of my appointment. Also, I really like the music playing…it’s really mellow…I heard The Beatles “Here Comes the Sun” and that really pretty acoustic White Stripes song. Super clean and bright with big windows too!

I recently moved to Fairfax and needed to find a new dentist. I picked dr. Yoon because of the reviews on here and was amazed at just how good he is. He was personable, friendly and very professional. He’s the only dentist I’ve been to who explained everything he was doing in terms I could understand. I would highly recommend him.

Josh K. from Fairfax, VA (Source: Yelp)


I’ve visited Dr. Yoon twice so far, both good experiences. What everyone wants in a dentist: speedy, polite, informative, and helpful. I got all of that, so I’ll be a regular patient of his. For both my visits, I was out of the waiting room and in the dentist’s chair in about 5 minutes. Treatment began promptly and there were no significant delays. My treatment was done entirely by the doctor rather than any of his assistants. Dr. Yoon was friendly, letting me know what was going on at all times. He told me about treatment options and worked quickly, without leaving me waiting by myself for treatment like a lot of dentists/doctors seem to do. I needed novacaine shots three times, Dr. Yoon did a good job minimizing the discomfort each time. I’m very happy with the one visible filling that needed to be put into my front tooth, it’s barely visible at all even up close. As for the office, it’s got digital x-rays, but I think all dentists have those now. Everything seems pretty modern and as comfortable as dentistry can be. The location is good too, right on Main St. Fairfax.

I was immediately impressed at how clean and calm this office was.  There was one other person waiting when I came first thing in the morning.  I went back and had my teeth cleaned, which was painless and easy.  Dr. Yoon came over talked to me about my teeth and answered all of my questions.  He was really easy to talk to, patient, and explained things so that a patient would understand.  I am happy to finally have found a great dentist!

I broke a tooth and made an appointment with my regular dentist and for whatever reason she couldn’t keep it. The tooth was so sharp that it was cutting my tongue so bad I couldn’t talk, drink or eat anything. When her office called to cancel my appointment I ask them to recommend another dentist. I waited for them to call back and it was so long I knew I needed a dentist asap. I called Dr. Yoons office and they got me in within an hour and I got amazing care. Plus it was several hundred dollars cheaper than my dentist,which I appreciate as I had no insurance and am a senior citizen. The Doctor and the staff are awesome, the office is very clean and I now have a new dentist and am so happy. Thank you Dr.Yoon and staff you are all greatly appreciated. Dr. Yoons had to put a crown on my tooth and I also had him take a old mercury filling out and put in a new filling. I have one more mercury filling that needs to be replaces and a front tooth filling that has turned a different color and doesn’t look very good and will be having that done after the first if the year. I can’t say enough good about Dr. Yoon and staff. I have been to several dentist in my lifetime and I am so happy about the care I have received from Dr. Yoon and staff. Please give them a try and you will have a great experience if there is such a thing going to a dentist. Lol. I liked the way he kept explaining what was going on and kept telling me how much longer it would be. Greatly appreciated. People who are afraid of going to a dentist believe me he will make your trip to him a pleasant one and take the fear away as much as possible.

A.B. D. from Washington, DC (Source: Yelp)


I read about Dr. Yoon here on Yelp, and that influenced me to use him, along with his very reasonable cost (about half the co-pay that my previous dentist would have cost). I will sound like I was paid to write this review (I was not–and, in fact, didn’t even mention to him that I would do so) because I have never had a better experience with a dentist. Dr. Yoon is very bright, teaching me things about my teeth and about dentistry I never knew, meticulous in making sure the crowns I got were perfect, very accommodating of my tight schedule, and a pleasure to talk to, with a sly sense of humor. (I should also mention that there was some magic in the way he administered novacaine: it was almost painless, and he gave me just enough so that it had completely worn off by about an hour after I left his office. Have you ever almost fallen asleep while getting your teeth drilled? I thought not, but I almost did–I was that confident and relaxed.) For those who might care, he’s American-educated, a fairly young guy–and therefore very much up on the latest dental techniques and research–and very personable. I was also impressed that he performed my teeth-cleaning himself on my first visit (I believe he has a hygienist, but apparently likes to get to know his new patients, and their teeth, well on the first visit). As with the restorative dentistry I had as a follow-on, he told me things about my teeth, mouth, jaw and dental history during my first visit that I don’t recall hearing from any other dentist. He just takes the time to educate and explain–I’d say he’s scholarly in a very low-key way. His office staff is also great: friendly, efficient, and helpful. I see now why everyone who has written reviews so far has given him the highest rating. Scratching for something to say to show some balance, all I can come up with is if you have to sit in the waiting room very long (and you likely won’t), you’ll be listening to bland Christian music. Back in the exam room, though, it’s classical–and, if you come in late in the day as other patients are clearing out, he might ask you, as he did me, if you’d mind if he switched to Clapton to finish the day. If he didn’t already have a new lifelong fan, he did after that! *** Edit: Aug. 12, 2013: It’s a year later, I’ve completed my treatment plan, and can only say I’m more impressed than ever with Dr. Yoon and his work. I have recommended him to many, and those who have gone feel the same as I do: from the purely technical side, he’s a fantastic dentist, but he adds to that personal warmth and intelligence, and very reasonable pricing. In response to the note I see from Helen C. on 1/2/2013, I can only point out that his is a one-dentist shop, and he is punctilious: I’ve never had to wait beyond my appointment time for treatment to begin. He also has a very strict policy on no-shows, so it’s a two-way street: you get his full attention during the time you’ve booked, but you need to be there on time. I suspect a side effect of that philosophy is that he can’t fit in extra time for unplanned services. In any case, I have never felt he pushed unnecessary levels of intervention; if anything, he’s a “let’s watch it for awhile and act only when it’s clearly necessary” kind of guy. He will also be clear when the moment has come. I like that kind of conservative dentistry.

What can I say, I am a fan of Dr. Yoon. I found him through my dental insurance and I have been with him for now over 6 years. Even though I live in Switzerland, I visit him every six to seven months to have my teeth cleaned. 🙂 I do believe I am his long distance patient

My family and I have been patients for a couple years now. We also have friends who are patients too. Knowledgeable and friendly staff. Clean and updated interior office despite the dated exterior appearance. If you’re looking for a new dentist I would definitely give this practice a try, you won’t be disappointed.

Katie T. from Fairfax, VA (Source: Yelp)


I saw Dr. Yoon today, my first dental appointment in over two years and I was very nervous. I got to the office early and was greeted by pleasant staff. The office was pretty– modern and neat with a TV on silent in the corner to help pass the time. I was taken back to my appointment on time. The first part of the appointment was x-rays which was nothing to write home about, then a brief discussion about my medical history and general dental history and concerns. Dr. Yoon did my first cleaning and explained that he likes to see for himself what kind of dental hygiene his patients come in with because it influences his treatment plan. I was worried about a crown and the need for fillings and Dr. Yoon looked at my problem areas and even showed me what he saw using a small camera that hooked up to a TV I could easily see. I would agree with the other reviews of Dr. Yoon saying he is a ‘conservative’ dentist, not rushing to treatment and considering my dental history I was relieved. He addressed my concerns professionally but used more of a ‘big picture’ approach to make decisions about treatment. I asked about invisalign at the end of the visit when I realized I wasn’t being signed up for tons of (unnecessary) treatment and he gave me some great referrals. Overall the staff was nice, the doctor was nice, the office was neat, and most importantly all aspects of my care felt non-threatening. I have my next appointment set and I set up an appointment for my husband while I was there too. Thank you!

Dr Yoon is amazing! My family came to visit us from U.K. and my sister’s experience a terrible pain in her tooth the next day arrival. I’ve called Dr Yoon at his emergency number and he explained everything about the situation for my family. We walked in to his dentist office without an appointment on Monday as her teeth hurts under too much pressure and very pleased that Dr Yoon was very comforting and understand the circumstances in our situation. I would recommend their office and Dr Yoon is the best. Two thumbs up!

Matthew H. from Spring, TX (Source: Yelp)


Great office, Dr. Thomas Yoon is very friendly and cares about his guest more as friends then paying guest. Very clean, easy to talk to! Rachel plays good music while waiting, the replacement plays Christian music so bring your head phones. Dr. Yoon even completes his own cleanings – that is hard to find around here!

Lynne D. from Potomac, MD (Source: Yelp)


I chose Dr.Yoon because I liked that he is meticulous and ethical in his dental work and his office has the most modern dental technology. I had a very complicated case and needed my old mercury amalgam fillings removed as well as a bad crown. Dr. Yoon follows the safest mercury removal protocol (many dentist do not) and so I avoided breathing in the poisonous mercury vapors during the removal process. I get compliments all the time on my smile now thanks to Dr. Yoon.  He also has low-radiation digital dental X-rays. After years of other unethical dentists and poor dental work, I have finally found my dentist.

Rasha N. from Alexandria, VA (Source: Yelp)


Dr. Yoon is a spectacular dentist, with what I would describe as a ‘conservative’ approach to dentistry. He does not recommend invasive or unnecessary procedures (as I have heard is the case with many dentists). He is personable, thorough, and informative; he quickly eased my fears stemming from a 3 year lapse in dental visits. The cleaning was comprehensive and painless, as well as educational. A few further perks: he did the cleaning himself + a friendly receptionist and no wait time for my appointment.

Jay S. from Burke, VA (Source: Yelp)


I’m usually terrified of dentists, but Dr. Yoon is the best when it comes to pain control. I had a wisdom tooth taken out 15 min ago, and even the Novocain shots were painless. I’m such a wimp when it comes to dental procedures, I cried during my root canal with my previous dentist. But I have to say, this is the best dentist I have ever had.
