I can't recommend Dr. Robert H. DeWitt and Dr. Hong highly enough. From the moment you walk in, the entire team is warm, professional, and genuinely caring. They make what is usually a stressful experience feel calm and comfortable. Dr. DeWitt is incredibly knowledgeable, thorough, and honest. He takes the time to explain everything clearly and never makes you feel rushed. Dr. Hong is equally exceptional--gentle, detail-oriented, and clearly committed to providing the best possible care. You can tell they both truly care about their patients' comfort and long-term dental health. The office is clean, well-organized, and runs on time, which I really appreciate. Whether it's a routine cleaning or more involved dental work, I always feel confident that I'm in expert hands. If you're looking for dentists who are skilled, compassionate, and trustworthy, Dr. DeWitt and Dr. Hong are outstanding. I'm so glad I found this practice and wouldn't go anywhere else. read more

I'd recommend this practice for any dental work you need - they're outstanding. read more

Recently went to Dr. Dewitt's office for a cleaning and checkup. His office and staff--particularly hygienist Katrina--remain the best!

My husband and I both highly recommend this practice. We are relatively new patients and have been so grateful to have found Dr. Dewitt. My husband is very sensitive to procedure pain. It is the first time during a 2 1/2 hour procedure that he has felt no pain for a procedure. Not only for the procedure, but the anaesthesia injection also elicited no pain. And Dr. Dewitt is also very thorough in his evaluation and recommendations. He is assisted by a team of nurses and hygienists who are extremely pleasant, capable, and obviously personally invested in the profession. Excellent work ethic. The team covers well for each other Also for front office duties. They are good about scheduling and paperwork. We are simply amazed. read more

15 year patient Dr. Dewitt and his staff are very skilled as dentists and know how to run a business. I've never waited more than 5 minutes to be sat and they get to work immediately. I get a very thorough cleaning and examination in an hour before work. Dr. Dewitt is also concerned with oral health beyond dentistry. He works closely with my son's orthodontist and keeps her apprised of any issues. I appreciate his care and diligence as a patient and a father. Dr Dewitt's practice is first rate and I recommend him without any reservations. read more

Simply the best Dentist in the DMV area! Dr. Dewitt and his staff are both professional and kind, and he brought me back from the brink where I would cry going into a Dentist office and now I am THRILLED to see him! Can't recommend him ENOUGH! read more

Have you ever wanted to hug your dentist? I'll bet many people can't say "yes". Dr. DeWitt did an amazing job replacing and adding to my veneers. He is a perfectionist, which I adore in a dentist. He is also kind and has an amazing support staff. I don't write reviews but he was so amazing I knew I needed to share. He is by far the best dentist I have ever seen and I will continue to drive 3 hours to ensure I see the best! I literally look 5 years younger after his expert work! read more

Dr. DeWitt is amazingly knowledgeable and patient! He has helped me through the process of getting a root canal from anther dentist. Before that, he fixed my bite on a new crown I got from a horrible dentist to see whether it was my bite causing pain or pulpitis of the nerve for which I needed the root canal. He is ever so meticulous in his work and explains everything so clearly. I would recommend him to anybody! I travel from DC to see him because a friend recommended him to me and he's amazing! read more

I have been Dr. DeWitt's patient for 33 years. He and his staff are professional, knowledgeable, and friendly. But what I appreciate most about Dr. DeWitt is his demeanor. He has a peaceful way about him that puts you at ease. That is so helpful for those of us who have had bad dental experiences in the past. I had an accident one weekend morning that took out several teeth in front. Dr. DeWitt opened up the office that Saturday morning and, with one of his assistants, was able to fix my teeth. You can't find many caring people like that anymore but his office is evidence that they do exist. read more

Dr. DeWitt is an incredible dentist and, more importantly, a caring and sympathetic person. Years ago my husband suffered from a botched up dental procedure, which only became evident on a Sunday. He was unable to reach the dentist, and in desperation I called Dr. DeWitt at home. He met my husband in the office and fixed the problem. As great as this was, it's even more amazing that my husband wasn't even his patient - I was! I'll continue going to Dr. DeWitt forever, at least as long as I can climb the stairs to his office. He even offered to carry me up, and I know he meant it. Too humiliating to consider. read more

Awesome caring skillful dentist. The entire office is excellent. He's the Doctors' Doctor....and that says a lot!

I have been going to see Dr. Dewitt since the mid 1990's, with the exception of a small break for 7 years when I lived out of the area. The minute I returned to the DC area, I went right back to Dr. Dewitt. They still had my file! He is a fantastic dentist - his staff is always efficient, polite, and great dental hygienists as well. I am "weird" about my teeth - in other words, I am one of those nerds that takes great pride in my Sonicare toothbrush, flossing regularly, etc. I feel like Dr. Dewitt is the same way - very detail oriented, concerned about both your appearance and overall tooth health, etc. He is by far the best dentist I have ever had - bar none. Other than the fact you need to file your own insurance claims to your dental insurer, and that his offices are in Tyson's Corner (I live in DC proper) everything is great about Dr. Dewitt. He is the only reason I ever drive to Northern Virginia. read more

You can expect honest, well explained state of the art treatment with Dr. DeWitt and his staff. I'm not only getting excellent routine care with hygienist Melanie, but due to my confidence in his skills and straightforward no-nonsense style, have embarked on the Invisalign process with Dr. DeWitt. His staff are very pleasant and professional--they always provide me with a completed claim form that I stamp and mail in to insurance without difficulty. Automated appt reminders much appreciated too. Highly recommend! read more

Dr. DeWitt is the fourth dentist I've gone to since moving to this area and definitely the absolute best. He was recommended to me by a trusted friend who's a long-time DC resident. In her words she, "followed him to the suburbs because he's so good." I don't live near Dr. DeWitt's office but am convinced he's worth the trip. After a series of mishaps at my dentist in DC regarding a crown replacement, I was in excruciating pain for weeks. She ended up referring me to an oral surgeon who didn't help me at all. Next, I went to an endodontist who gave me a root canal through my tooth with the new crown. Thankfully, this procedure alleviated the pain. Afterwards, I was advised to have that crown replaced. Despite the fact that my dental insurance was not valid at Dr. Dewitt's, this is the point when I decided to go to his practice. His motto is "Gentle And Thorough". He is that and much more! First of all, Dr. Dewitt listened to my concerns, then explained my options using x-rays and answered my questions. He is a caring professional who gave me outstanding service along with peace of mind, which is priceless. read more

Dr DeWitt and Melanie (hygenist) are fantastic. Their expertise and experience made my visit quick, clean, and comfortable. The conversation is also free flowing as they listen to all your concerns. You're in good hands with them! read more

Dr DeWitt and his staff are incredibly knowledgeable, thorough and kind. He is meticulous and seriously does not let anything get by him. I am in for an extensive, complicated dental treatment, and I'm really happy I found him. My family is/are switching over to him. read more

I once had a friend in the dental field. She directed me to a dentist whom she said was the best in Washington. I went to him and he said, "Why are you coming all the way into Washington? I'll give you the name of the best dentist in Northern Virginia." That's how I got Dr. DeWitt. I've been happy every since. Dr. DeWitt is highly competent, communicative, gentle, thorough, and precise. He also has a wonderful staff. Can't imagine going anywhere else. read more

Highly recommend Dr. DeWitt. At my checkup he was thorough and the staff are very nice. Months later, I had a dental emergency and I was in a lot of pain. He was gentle with the exam and diagnosed me with bruxism (teeth grinding) and made a mouth guard for me that day. Really helped me with what can be a very confusing and painful problem. read more

Dr. Dewittt does not accept insurance. The fees he charges are about the double of customary. If money is no object Dewitt maybe a good fit for you. For conservative dentistry - no cosmetic modern dentistry - it could be a good office to go to. read more

Dr Dewitt is hands down the best dentist I have ever been to. He does exemplary work, is very patient and gentle, and explains things thoroughly. He graduated first in his class and Georgetown, and also loves to scuba dive. His office is very clean and inviting. If you need a cavity filled (which is rare for me, because he takes such good care of me!) he will numb up the area and even provide nitrous oxide if you need it to relax. My daughter now goes to him, and also thinks he is great. Finally, his dental technicians, who do the cleaning, are all excellent and very nice. Just be sure to schedule your cleaning appointment in advance, as they do get booked up. However, if it is an emergency Dr DeWitt is always available. You can't go wrong with this choice. read more

Great dentist. Very personable and the staff is great. I wish it were painless, but they do a pretty good job.

It has been more years than I care to admit not going to the dentist due to extreme anxiety from bad dental experiences. But once I spoke to Dr. DeWitt and then saw him and his fabulous staff of professionals for my first appointment, my fears melted away. They made me feel so at ease and practically like family. If I was feeling any discomfort I would signal and they would stop and then proceed with the utmost care to my comfort. They were very communicative and told me what to expect and how they would treat it. The time they took to address my questions and concerns was gracious and generous. I really can't say enough about how much I like Dr. DeWitt and his staff of administrative professionals and hygienists. Not that I love going to the dentist, because who does, but I no longer dread and avoid it. For me that is due completely to my positive experience at Dr. DeWitt's dental office. read more

Moved to NoVA area from Chicago and have been looking for a dentist for over a year now. I have visited over 11 dentists in Metro DC and surrounding areas (Bethesda, Friendship Heights, McLean, Reston, Ashburn, UMD dental school in Baltimore)based on referral, word of mouth and reviews of various sources. My brother is a dentist (but is overseas currently), so I can tell a good one from a scam artist. I have very high standards when it comes to finding a skillful dentist. So far, doctor Dewitt's office ranks among the highest of all I have visited for consultation. 1. Dr. Dewitt is very thorough and pay attention to details. His touches are gentle. You can tell he is very skillful and experienced. Not like other who have years of experiences, but was very clumsy when they stick their tool in your mouth. He charged higher fee for consultation, and refused to use the 7 months old x-ray films I sent in. Therefore, I had to pay for the full mouth x-ray. So the consultation come to about $250. But Dr. Dewitt did gave detail written reports. 2. Both the office staff and dental assistant I encounter are not just courteous but very professional. I especially find the office manager, Arink, extremely organized, knowledgable, and efficient in her work. Before and after my two consultation appointments, I had called the office numerous time for treatment plan, additional appointment, and ask the Arink to pass on the x-ray file. I was in awe on the way she handle each task. She always provide me with the right info in a timely fashion. She is the best I have ever encounter for a long time when it comes to front office staff in any medical/dental office. Simple the BEST! 3. I give this office a 3-star because a) the fee they charge for crowns, filling, etc is the highest of all I have visited; b) the treatment plan are among the most aggressive of all I have visited. read more

I have been going here for 16 years and have never been disappointed. This practice has worked with my orthodontist, fit me for night guards, taken me in for emergencies, and have educated me on proper oral hygiene. Both of my parents go here as well as my grandfather. You know the work done at an office is phenomenal when a 91 year old afraid of doctors gives the thumbs up. Not only is Dr. DeWitt an outstanding dentist but his staff hold themselves to highest standards for patient care. No matter where I am I will always come back to this office. read more

My experience with Dr. DeWitt and his staff is nothing but perfection. He is undoubtedly the best dentist in Northern Virginia. The office staff is friendly and helpful. I know when I walk in the door, from start to finish I am getting the BEST dental care possible. So if you're looking or thinking about looking for a practice that understands your dental needs and help you achieve them. Look no further! You'll be amazed... I promise you won't be disappointed! S. Howe (a loyal & privileged patient) read more

Dr. DeWitt is just an extremely all around trustworthy person, and that is what is most important to me in a dentist. He has helped me and members of my family with any number of dental "emergencies" large and small from losing my crown during labor to replacing fillings and regular cleanings. He is also kind and gentle, and while he does not process insurance claims, his office will assist in filing for you and his prices are straightforward and reasonable. I know this because I have been to other dentists closer to home or who take insurance, but once again, I am back, along with my mom, my dad, my daughter and another family we know. read more

I have been an extremely satisfied customer of Dr. DeWitt for 16 years. He is by far the most superior dentist I have had. He does high quality work and is very thorough. He repaired my two front teeth and added a crown to a molar 16 years ago. Both jobs are still in great condition. I am amazed at the detail both the doctor and my hygienist Melanie know my mouth. They both notice potential problems before they become serious. I was diagnosed with Bruxism and fitted with a mouth guard that has saved my teeth. They also identified gum recession in a portion of my mouth and recommended modifying my brushing before I caused serious damage. Dr. DeWitt is easy to talk to and very informative. read more

Best dentist I have ever had. Great work and attention to detail, and always friendly. Just wish they would submit insurance forms for you. Also a bit pricier, but if you want it done right it is worth it. read more

Office staff are friendly and organized; hygenists are attentive and thorough, Dr. DeWitt is informative, careful, answers questions, provides details and options. I've been going to this officer for 18-19 years and have nothing but praise. From emergency advice by phone from another country to routine care over the years, Dr. DeWitt and his team provide high quality care. No doubt about it. read more

Dr. Robert DeWitt and his staff are absolutely the BEST! A few years ago, I did extensive research for some dental work I wanted to have done. As a result of my research and the recognition that he had received, I decided to work with Dr. DeWitt. I could not be happier with my decision to work with Dr. DeWitt and his fantastic team. They are very professional, yet appropriately empathetic when you need someone to be during a procedure! Based on my 3+ years of experience, I highly recommend Dr. DeWitt and hope he never retires!! read more
