I am a loyal patient at DuPont Dental for many years. They have the best customer service. The staff are cheerful and friendly and the office is conveniently located from my work. I never felt pressured to get unnecessary things done and they provide high quality and impeccable service. I highly recommend this gem of a place. You will not be disappointed.

Great care and they saw me on the same day after I requested an emergency appointment. Dr. Banks and his team were fabulous!

I have been a patient of Dupont Dental for years. They are one of the best dental practices in the city. The staff is amazing and make going to the dentist a more enjoyable experience.

This is a lovely office, and Dr. Seiden is a great dentist. However, the billing and insurance practices that this office uses are simply unacceptable and the reason for my low rating. After two standard cleanings and one round of routine x-rays, I received a bill for over $400! Mind you, I had dental insurance at the time of both visits. Unfortunately, this office has decided that they are out of network with every dental plan, and they balance bill patients for any amount not covered by their dental insurance.

This is a predatory and frankly unethical practice, and this provider should be held accountable. After numerous calls and emails with the practice, they ultimately dropped my amount due to $240. I will be finding a new dentist.

COVID precautions were thorough and made me feel very comfortable. And I love everyone here. The visit was, as always, thorough and as pleasant as a dental cleaning can be.

Every time I come, the dental technician remembers some part of my background, which makes you feel comfortable. Never a wait, in and out within 30 minutes. If you're fed govt, choose Aetna dental and you'll pay nothing for a cleaning and X-rays every 6 months. Office staff handled insurance and I don't have to do a thing. Making appointments is super easy with their email and text reminders. Been a patient for about 3 years, would highly recommend!

I agree with the reviewer noting the rudeness and condescending manner. I had such a bad experience many years ago that I still am traumatized. He may be a good dentist technically - I have no idea though because he irrationally blew up at me for literally nothing. I had been in already and had a good experience with another dentist in the office.

There was later a relatively minor issue regarding scheduling and he came out and started screaming in a way that quite frankly was abusive. I don't think he has any idea how hurtful his behavior is. Not exactly the best temperament for a dentist. The positive reviews I see make me think they aren't for Mr Seiden himself. Or these patients are very fortunate in not seeing this side of him.

I've been going to Dupont Dental for ten years and have always had a great experience. Dr Seiden is great, honest, and generous. The staff are always lovely as well. My whole family goes there now as well. They're the best!

We always have a great experience and on time service! The longest time I've ever had to wait was 10 minutes. Our friends were here visiting last summer and had a dental issue. She called they were able to fit her in and even stayed past business hours to accommodate her. Outstanding service!

Kris at the front desk is great, she got me in on short notice because I was unhappy with some cosmetic stuff that had been done by my regular dentist. He was able to quickly polish my teeth and fix the issue in no time (the only downside was I didn't know until checking out there would be a fee but expected it once he started working) but that was my fault and I should've double checked before he got started (I was just scheduled for a free consult.) Otherwise, great experience and really appreciate Dr. Seiden and his staff! Will be coming back here for all my cosmetic needs.

Updating my prior review. Though that had initially charged me over and above what my insurance covered, when I called them they were extremely helpful and lowered my bill by the amount that was not covered.

I came for a visit to get an opinion from Dr Seiden regarding my two front teeth being slightly chipped. He right away said that he was the best dentist to do cosmetic dentistry. When I asked about the cost he told me $3600 for two teeth. I of course asked if my insurance would cover some of it, he said he was not sure but my insurance could cover up to $900 per tooth so half of it per tooth.

I wanted to make sure of it and I said I needed to think about it. That is when he said abruptly "Sebastien you took an appointment now we need to do it." I feel like an idiot for being pushed over like this. When I got the crowns I said right away that the teeth were too long and that I looked like a rabbit. Now to make my mouth even I have to do the other teeth next to the two front teeth to make it look even.

I feel horrible my insurance is covering only $300 out $3600, had I gone to a dentist in my insurance's network I would have paid half of it. That was a miserable experience, I am really upset by the result and the process felt so wrong to be pushed into something I was only researching options to begin with. Furthermore when you are uncomfortably laying with your mouth opened Dr Seiden talks to his assistant about a multitude of things and you literally feel inadequate in that seat, like you are not existing and if you complain that it is painful he gets quickly irritated with you. Lastly when I confronted Dr Seiden about my disastrous experience and the unsatisfactory results he told that I needed to find another dentist. I have never felt used like this ever. The bottom line is that I am so self-conscious about my uneven smile that I don't smile other than with my mouth closed.

Usually love Dupont Dental but I recently went in for Zoom Whitening. After a painful procedure (not Dupont Dental's fault!), despite clearly being in pain, I got a few sarcastic quips from Dr. Seiden which were not appreciated given the level of pain i was visibly in. Furthermore, I was told by the front desk they would 'call the next day to check in on me'.

Never happened. Funny for a company that will call and email five times to confirm an appointment they can't spare the 2 min gesture to check on a patient's well-being.

I don't think I've ever written a yelp review, but my experience was bad enough to make me sign up and post this. I would REALLY not recommend this dentist. He's completely untrustworthy and will try to take advantage of you.

Dr. Seiden is fantastic and the office staff were friendly and efficient. One of the best experiences I've ever had with a dental appointment.

I am terrified of dentists so going is always a personal obstacle i need to overcome. This is by far the best dental office i have been to. I had to get 11 cavities taken care of they did in in 2 sittings and were so amazing. The first time i went the doctor had an emergency case and was running late, he came out personally to apologize. There is the option of Laughing gas for those of us that freak out in the chair. They are very attentive to that and treat you accordingly. I appreciate the kid gloves for the scary cat with horrible teeth.

Very good dentist. Bedside manner leaves much to be desired. Kris, who runs front office, amazing! I had to cart my 3 YO to the appointment, which is not as much fun as it sounds. He was not happy, but it's not like I had many other alternatives. Enter Kris, who gave my daughter a bracelet, some dentist toys and talked to her during my x-rays.

She was the reason I didn't walk out. If you can get past his grouchy attitude, then go. If you have kids that you can't leave any where and must take with you, pack extra doses of patience. He is a good dentist, I think he just needs a hug. :S

I called Dr. Seidan hoping for an appointment and left a message. He called back with an attitude right from the start, as though he was very put out that someone wanted an appointment and he was doing me a favor by calling me back "from his home." When I asked if he accepted BlueCross BlueShield insurance he got even more huffy and explained to me that there were many types of BlueCross BlueShield insurance plans (as though I was not already aware of this).

Instead of answering him (because at this point I was annoyed and taken aback by his demeanor) I asked if he was in-network for any BlueCross BlueShield insurance plan, which he isn't. I guess I'll just keep trekking out to the Arlington Center for Dentistry - at least they are respectful to their patients and have a legitimate business operation!

Dupont Dental Associates is a friendly, welcoming place to visit for your dental needs. You can request an appointment online, which is helpful. The receptionist, Kris, is great, and I love the hygienist, and Dr. Seiden. My appointments have always started on time and been quick. They are great with the reminder e-mails as well. I highly recommend if looking for a dentist in the Dupont area.

Dr. Seiden and Kris are the best! I have honestly never had such a pleasant, quick and painless experience at the dentist as I had today. I wasn't pressured to buy anything cosmetic or useless or bullied into any unnecessary procedures. It was great! The cleaning was excellent, everyone was friendly, funny and accommodating. I didn't wait long at all before my appointment. Dr. Seiden explained everything he was doing and cracked some jokes.

I also appreciate that I was in and out in no time but I felt that the perfect amount of attention was paid to my pearly whites. My last dentist was DC Dental Spa (see their page), and they were the ABSOLUTE worst, this was a full 180 from that. I'll never go to another dentist in DC.

Dr. Seiden and Kris in front office is awesome. It's rare to find a front office who is so organized, friendly, and on top of things. Sometimes I put up with a incompetent front office b/c I like the dr., but here, you get the whole package- great service everytime! Dr. Seiden is friendly and always puts me at ease during my check ups. I also LOVE their little patient kit they give me after my cleanings. It's the little things that make them 5 stars in my book!
