W Plus Dental
Tae Sung John Ku, DMD:
Practice Profile Page

I don’t usually take the time to write reviews, but seriously Dr. Ku is the most professional and thoughtful dentist that I have been to. Unlike many medical professionals, he takes the time to sit and answer your questions. You never feel rushed and he never tries to upsell you. His entire team is courteous and generally focused on customer service. I’ve never had to wait for my appointment because they are always on time. I highly recommend his office.

W+ Dental is the best! We’ve been going there for about ~3 years now and even though we’ve since moved further away, we still make the drive back because they are worth it! • Office is clean and sanitary • Very friendly office staff / hygienists • Very easy to communicate with (your choice of calls, emails, or texts) • Nice dental equipment • Very thorough / detail oriented • Dr. Ku has a hypoallergenic emotional support dog to help comfort patients. To be fair, I’m not sure if the dog is there all the time, so if this is important to you, you might want to double check! He’s been there every time we’ve gone, but that could just be a coincidence!

Went here for an emergency when an old temporary crown fell off, and Dr. Ku was so accommodating and helpful that I kept returning. He makes treatment plans for his patients that are clear, understandable, and work with your insurance and schedule. All the staff are talented and I’ve had nothing but excellent service and dental work done here. They always let you know the price of services before you schedule the next appointment. I’d recommend this office to anyone.

Dr. Ku and his staff at W Plus have been a fantastic find. The front desk staff is excellent. They’re well organized and provide information on insurance payment ahead of the visits, along with regular visit reminders. Their equipment is all new, including the 360 x-ray machine which is much more comfortable than the individual x-rays I received at my old dentist. After my first cleaning, the hygienist located three potential fillings, which Dr. Ku observed and confirmed. He took photos of the teeth with a small camera and was able to show me the specific locations where the fillings were needed and compare them to several other locations that were fine. I’d never seen a dentist use a tool like this, and it was helpful for me to be more informed going into my fillings.

I suffer from sever dental phobia. The people at the office put me at ease. The front desk guy, I forget his name, blonde guy was so sweet. Micah cleaned my teeth so gently & taught me how to properly floss and brush. She’s so sweet. Dr.Wolf was so understanding and worked hard to make sure I understood the drama with my teeth. Kim took the time to sit me time and explained payment arrangements. This office is incredible.

John is by far the best dentist I have had. I have been always so afraid to see a dentist and I have been avoiding it for the longest time. John totally changed my perceptions of a dentist visit and I have actually enjoyed it. First, the place is so nice and clean and it felt like a spa. John was so patient, gentle, professional and honest. He performed the cleaning and three cavity fillings so carefully that I barely felt anything. He also made me a detailed treatment plan and explained everything going on with my teeth to make sure I get the best care. His staff are also so nice! He and his staff made sure I was comfortable through every single procedure multiple times. I will go back to see him soon and I can’t wait to have all my dental problems solved! I highly recommend everyone to go see John if you ever need to see a dentist!

I highly recommend Dr. Ku’s office. The interior design is clean and modern, and there was an easy check in process (computer). His assistants were always courteous and checking in with me every step of the way to see if I was comfortable. They have staff that speak English, Spanish, Korean, and Tagalog. On top of that, after Dr. Ku finished the cleaning and identified cavities, within a few minutes they prepared treatment plan ready for me with costs listed out. There was full transparency the entire time on costs with insurance. He was also very patient and answered all of my questions. Hidden gem in DC and conveniently located a block away from work. Their therapy dog, Bali, as well was so sweet!

Dr. Ku and his staff are absolutely outstanding.  I am visiting Washington DC for 2 years and I feel fortunate the stars aligned for me to find Dr. Ku.  I had a couple of procedures done, one of which was a bridge replacement that resulted in a smile makeover.  Dr. Ku was so helpful throughout the process and I could not be happier with the results.  He is a perfectionist and very attentive to every detail.  I highly recommend Dr. Ku and if you go for a visit, you too will experience a very efficient yet caring practice that provides top quality service.

This practice is an absolute DC gem. My husband and I were searching for a new dentist last summer after multiple disappointing customer service experiences with our previous dentist.  We were immediately impressed by Dr. Ku’s practice, including the tech-forward office (but not unnecessarily so), ease of making appointments, and fantastic staff and technicians.  Dr. Ku himself is simultaneously extremely personable yet impressive, with a bedside manner that immediately puts you at ease and instills confidence in his capabilities.  My husband and I have each seen Dr. Ku now for two cleanings and a minor dental procedure, and I cannot recommend Dr. Ku and his team highly enough.

I was looking for a new dentist in the DMV area and I couldn’t be happier I found W+ Plus Dental. The office is great with all the modern bells & whistles, and Dr. Ku and his staff are attentive, easy-going, friendly and super efficient. And I would be remiss to not mention Bali, who is the most adorable therapy dog I’ve ever seen!

It’s always daunting to find a great dentist in a new city after having the same dentist for years. While the office is brand new, Dr. Ku and his lovely assistants are incredibly knowledgeable, professional, and really deliver beyond just the basic needs of their patients. It also helps that Dr. Ku uses the latest technology in dentistry so everything he does is highly efficient. I had to get a root canal & crown on a tooth that needed some work done, but the procedure/process was a breeze (I even joked that I kept drifting off to sleep because I was so relaxed). All this to say, I’m glad my search for a dentist is over! And I’m actually looking forward to my next appointment for my routine checkup. PS – Dr. Ku brings his adorable toy poodle named Bali into the office as a therapy dog. Just sayin’

Both Dr. Ku and Dr. Wolf are great dentists – efficient, but not rushed. Both dental hygienists I’ve had were thorough and respectful. The front desk staff is friendly and helpful (though everything runs pretty smoothly). The office is clean, well-lit, and professional. It’s helpful that the bike share is right outside as well.

W Plus Dental is exceptional from the front desk to dental assistants, hygienists, to Dr. Ku. They are extremely professional, take advantage of the latest technology and practices, and only recommend what is necessary. The trust level with a dentist is one of the most important things, and I completely trust their diagnosis and recommendations. They are also very gentle and made me feel comfortable with what they were going to do, comfortable while they did, and provided excellent follow up care after. Integrity, care and excellence are all words I would use to describe this practice. I highly recommend W Plus Dental.

By far the best experience I have had at a dentist. Dr. Ku and his staff were very friendly, but above all not dismissive and pushy. Every trip to the dentist as an adult for me has been filled with lectures, and aggressive upselling of procedures and products. That is not the case here at all. Light touch on the work, carefully explained every single step. I had to have 3 appointments over a 2 week period with 4 separate procedures. They were very accommodating and helpful. All new patient paperwork is done on a tablet when you check in and they gave me an exact breakout of all the costs before starting the procedures. These costs were also about 20% less than what I was quoted at other offices for the same work. If you are like me, and dread going to the dentist not just because of the discomfort but because of the aggressive nature of most modern medical offices then I highly recommend this practice.

Haven’t left a Yelp review in years but I had to today after my visit to W Plus! This is  my 3rd dentist in the DC area and by far the best. Mika (sorry if spelling is wrong) was SO gentle with my cleaning, which is a huge plus for me. I presented her and Dr. Ku with the recommended work from a previous dentist and they said it wasn’t necessary, which is what I suspected and why I left my previous dentist (they were trying to charge me $600+ for work it turns out I didn’t need!). Excellent experience and I’m already returning in a few days for a filling which (with my insurance) will only cost around $30. And their therapy dog is so cute!

Incredible experience from start to finish. The staff is friendly and extremely knowledgeable. Their equipment is state of the art. The service was quick and also very thorough. Dr. Ku is well educated and truly cares about his patients and their well being. This was by far one of the best dental experiences I’ve ever had.

Dr. Ku is simply the most competent and kindest dentist I’ve ever seen. I usually don’t write reviews, but I felt as though Dr. Ku and his staff went out of their way to make sure I have the best possible experience while at a dental office. I’d say I am pretty careful in choosing my dentist and it took me a long time to find a new dentist after I moved to DC. I sought out numerous recs from friends and family. On the first day, I immediately noticed the excellent skills and professionalism. On top of that, the kind of personalized care I received was beyond my expectation. He answered all my questions carefully, completely from the patient’s perspective. I was provided well informed options and recommendations for treatments in both short and long terms. I’ve always been incredibly happy and confident with his care. I’m so grateful for Dr. Ku’s expertise and dedication to his work. There’s a reason they have the 5-star rating, and I cannot recommend him highly enough. My only worry is that the word might spread quickly and the office will get too crowded.

Legitimately best dentist I’ve ever been to, hands down. Dr. Ku was extremely professional, knowledgeable, and flat out just a really nice person. He made me feel extremely comfortable, which was huge for me because I tend to really dread the dentist after some bad experiences. The receptionist and hygienist were also great, as well as super friendly, and welcoming. The entire experience was painless and professional, and the office is pristine and new. Every question I had was answered and explained, and they took the time to make sure I understood the breakdown of cost. Additionally, when educating me about products I could purchase from them, there was no pressure; it was entirely up to me if I wanted to move forward with a purchase or not. It’s always frustrating to go somewhere and have the team harass you into a decision you might not be ready to make yet. There was none of that with W Plus. I have already told a bunch of friends who need a good dentist in the area to go here and for once am not dreading my future dentist visits!

It’s always tricky to find a good dentist when you move. I went through a bunch of them before I reached W plus: everyone was nice; everything was clearly explained all throughout my appointment; my options were laid down in front of me and Ashley even made the effort to check with my insurance and go back and forth between us to make sure I got the best deal for me. Dr. John was very genuine, attentive and actually sat down with me for more than 5 minutes, unlike these big practices where you don’t get the same doctor twice i.e. the recipe for medical errors. For once, I was treated like a human being instead of a moneybag. I come from a warm and friendly culture and I don’t take that statement lightly. Otherwise, the clinic’s design is beautiful and relaxing, a nice cherry on top!

Fantastic experience. Everything here is brand new, clean and modern. My retainer fitting was done with a fascinating electronic device that you can watch on a screen as opposed to the old fashioned mold.  The staff is very nice and there is even a small poodle that will sit on your lap. They are also much less expensive than most dentists. I researched dentists to replace a fitting and W+ was literally thousands of dollars cheaper than anyone I found in DC.

For everyone who lives in the DC area, go see doctor Ku at W+ if you ever need to see a dentist. He is the most honest and caring dentist you will find GUARANTEED! Last year, my husband and I bought a Groupon to have a regular check-up and teeth cleaning at Merrifield Smiles, but they wouldn’t redeem it unless we did unnecessary and ridiculously expensive works with them first. My quote was $1600 and my husband’s was $600 after in-network insurance coverage. We totally felt like we were being ripped off and left without using our Groupon. My husband went to see doctor Ku later instead and got everything he needed covered by the insurance. I will go see him after our trip is done for sure!

A+ for W+ Dr. Ku and his team is the best. I’ve made several visits to W Plus Dental over the last few months for different services (check ups, cleaning, wisdom tooth extraction, clear braces etc) and I can honestly say that I’ve never been let down. The entire process is seamless, from appointment set-up to treatment to follow up. Visit after visit, I feel cared for by the entire team and I can always trust them to provide the best personalized treatment/services for my needs. I’ve been to several dental offices over the 6+ years I lived in DC and I can confidently say that W Plus tops every one of them. The friendly team and their teamwork. Quality service. Modern equipment and clean office. Convenient location. Dr. Ku’s adorable dog, Bali. What’s not to love about W Plus? I’m so thankful for them and hope to return for many years to come.

Dr. Ku is my dentist since when I lived in Boston, every visit was pleasant, great experiences. His brand-new DC office (W plus dental) has the state-of-art equipment as well as clean and comfortable space. Moreover, the hygienist and receptionist were great, and the dentist himself was very professional and friendly. Recently, I went in for a routine cleaning and aesthetic reasons (temporary veneers), and I could tell that he is very knowledgeable, he explained all different options and approaches to me before the procedure, and he recommended me the most cost-effective option. Also, he spent extra time to make my teeth cleaned and looked flawless. I highly recommend W plus dental by Dr. Ku for those who are looking for experienced, friendly dentist and staffs and clean, spacious dental office in DC area.
