Dentists On Washington

I really love these guys. I’ve been coming here for about a year now, and the service is equally good every time. I’ve had some pretty horrible dentists in my lifetime, so I was relieved to find that everyone here is super friendly, prompt with seeing me (appointments usually never take longer than 45 – 60 minutes), and upfront about every procedure I’ve ever had done here. Unlike other dentists, I never felt coerced into getting braces or tooth whitening – instead, Dr. Ngo explained the pros and cons of both of these services, had another employee call the insurance company for me to see if Invisalign was covered, and gave me a price breakdown on the spot.
Also, I love their other perks, like free chapstick that smells great and a bottle of water when it’s hot in the summertime. The little things count.

Fantastic!
I first visited Drs. Ngo and Costello on a Saturday afternoon with a dental emergency — a problem that my other dentist had repeatedly misdiagnosed and been unable to resolve. Drs. Ngo and Costello immediately saw what the actual problem with my tooth was, and stayed at their office well past closing to help me. They are both clearly very skilled at what they do but also genuinely care about their patients (and I had *just* become their patient when I walked in the door).
My next appointment with them was to fill a few cavities — cavities other dentists had missed. Drs. Ngo and Costello walked me through the x-​rays explaining each cavity and pointing out their positioning so I knew they were there.
I can empathize with the reviewers here who (for some reason) believe they couldn’t have had any cavities as other dentists had told them as much. It was disappointing to me as well (because I brush and floss 4+ times a day) but hey, you can’t argue with an x-​ray photo. The cavities were there, they needed to be filled, and they were — very well. No pain, quick procedure, no toxic fillings. Excellent!
Their office is lovely, clean, and new — and it is the only eco-​friendly dental office in Philadelphia.
They are super trustworthy and clearly not afraid to tell you the truth about your teeth — whether the truth hurts or not (pun intended).
I recommend their services to everyone I know. You can’t go wrong with them.

I must say that dentists on Washington is probably the best dental office that I have ever encountered. As a patient, I can honestly say that Dr. Costello and Dr. Ngo are very thorough and thoughtful when it comes to treating their patients. They always explain everything that has to be done procedure wise. While doing exams, they show patients any cavities that are found, both on the x-​rays that they take, and while doing the actual exam, by using a mirror. many a patient had said that they are put at ease when they come to this office, whereas before at other offices they have been very nervous. While I myself have never had a bad experience at a dental office, I too also felt completely at ease when I had my exam done, and all of my dental work, which included a filling, root canal, and a crown. I also finally convinced my father to come in to get an exam done, since it is necessary to get all dental work done before he is able to go through with more treatment for the cancer he has. My father is not a fan of going to any doctor, not at all. The first words out of his mouth when I took him home, were «Dr. Costello has a gentle touch, and I was very impressed with the cleanliness of the office and all of the equipment that they have to work with.» He is actually looking forward to coming back in to get his work done. Both myself and my father (who doesn’t use a smart phone or computer) highly recommend this dental office for your dental needs. And an added bonus for patients who are nervous about getting any work done, they have IPads so you may watch anything on Netflix to keep your mind off of your procedure! Any questions you have about anything are always answered before they begin working on you. You are always greeted with a smile from Tiffany and Karena, as well as both doctors!

One of the best (if not the best) dental office I’ve ever been to. Like most people, I am always a little anxious when going to the dentist. However, Dentist on Washington has made my experience at the dentist best one yet! The staff are all very friendly and helpful. The office is very nice and cozy, plus convenient location and you don’t have to worry about parking! Both Dr Ngo and Dr. Costello are very knowledgable, they explained to me well about what they are gonna do and what I need to do to take better care of my teeth. Plus, they are very gentle and thorough! They definitely put me at ease in the dental chair! And their dental office is eco friendly! Bonus point for the environment! I highly recommend Dentist on Washington if you are looking for a great dentist in Philadelphia are!

I went in for a normal cleaning/​exam, and the dentist told me I had 7 cavities, which was odd to me because I had had only one in my whole life that needed filling before. I didn’t have dental insurance at the time, so I was hesitant to get them all done as it would have cost me over $ 1000. I asked if the cavities could be prioritized in order of urgency, and he replied that they were all of equal importance.
I went back to the dentist I normally use to get a second opinion. He took X Rays again, and NONE of the cavities were problematic to the point that they needed to be filled. My usual dentist considered the approach of filling them all «overly aggressive.»

It can be difficult to find a good dentist or doctor. They talk you through everything they do. Very attentive to any and all questions. I always have questions, a lot are anatomy based and my interest for what, why, and how things happen. Dr. Ngo and Dr. Costello patiently answer all my questions.

Going to the dentist is not enjoyable. But this place makes dental treatment as pleasant as possible. The staff, admin and medical are extremely friendly, welcoming and informative. They did their best to maximise my insurance benefits and helped me prioritise the treatment needed. The medical team explain in detail everything they are doing and why they’re doing it. They follow through on customer service too. Recommended to me by a friend and I will recommend onwards. My dental benefits are with Cigna and they worked with Cigna for direct billing. They also took card with no fuss for the co-​pay. Keep up the great work Dentists on Washington– amazing!

Not Good!
I never really post on here but I wanted to warn you all!!! I went here and Dr. Ngo said she found 15 cavities and gave me a price list of all it would cost me to fill each cavity. She said she could get started right away if I wanted. I have never had more than 2 cavities at once so I was very skeptical when she said 15. I asked Dr. Ngo to rank the cavities and I asked what were the most severe. She said all were very important and that we should fill all based on what side of the mouth they are on, not the order of importance.
Medical health is like buying a diamond ring, you have to trust the person providing it. I sent my x-​rays to a different dentists (family friend) and went into a third dentist. Both of the other dentists found 1 cavity. The third dentist examined my mouth and X-​rays and said in order to get 15 cavities, Dentist on Washington would have to refill old cavities (which were in good shape).
The staff are very nice and the office is clean. BUT it seems like they were just getting me to pay them for extra work !! BE CAREFUL!!!
Has anyone else had this experience?

We have been using this office for a year and a half now, after finding them doing the same thing you are doing, searching on Unilocal for actual experiences with the office. I could not be happier with the choice! Both dentists do a wonderful job, so it’s great that you can see either. The entire staff is friendly, the office is clean and modern plus they understand working parents with their flexible office hours. They make going to the dentist thoroughly enjoyable!

I feel very comfortable, they are professional and friendly, very easy to make appointments. I trust them with my teeth and my children’s teeth.

Was referred to this practice by a neighbor and boy am I thankful! My 2 year old son and I went over the weekend. It was my son’s first dental appointment and my first in a few years. The waiting room was very pleasant and I was not in it for very long… I just completed basic paperwork and Dr. Costello was ready for us. He was great with my 2 year old; very patient and warm. I do not typically enjoy a visit to the dentist, but I actually would say I enjoyed my visit with Dr. Costello. He was personable, pleasant and treated my mouth with care. His cleaning was very thorough and my mouth felt great afterwards. He took extra time to talk with me and answer my questions. I will be back again in another 6 months! I highly recommend this denitst!

I’ve lived in Philly for the past 2 years, and I’ve been a patient of Dentists On Washington for the last 1 year or so. I am SO HAPPY that I picked this place. I’ve been seen by both Dr. Ngo and Dr. Costello (husband and wife team), and they are both so professional, friendly, and informative.
Each time, they were thorough in their approach (I had deep cleaning & minor cavities filled). They were accommodating, making sure that I was in no pain. Like the other review said, I would not mind sitting in their chair — I felt that I could talk to both of them for the whole day if I didn’t have gauze and a sucking hose in my mouth!
Their staff is extremely accommodating as well. I even asked the receptionist advice about switching dental insurance, and she came back to me with a detailed, handwritten list of plans that she’d recommend, after seeing my needs and appointment schedules.
So, in short, I would totally give them more than 5 stars if I could. It’s great to see a family practice in the neighborhood.

By far the best dentist I have been too. My wife and I have been impressed each time we have visited. From making an appointment trough payment they have made going to the dentist a good experience. The office staff always greet me by name even though we have only been there a few times. Both Dr Costello and Dr Ngo thoroughly and simply explain everything they do and just in general are really nice people. I would recommend them to anyone.

This is hands down the best dentist office I have ever been to. Not only is Dr. Costello a super nice guy he also gave me the most thorough basic cleaning I have ever received at a very good price. The office is very clean and modern and the instruments and chairs are top notch. I cannot recommend this office more.

I absolutely love this dentist office! I’ve had so many terrible dentists in the past, especially when it came to the ladies at the front desk. Right from making an appointment over the phone to checking in to getting a dental cleaning, all was so positive. LOVE everyone that works there.
Dr. Costello is also extremely friendly!
HIGHLY recommend!

I have recommended everyone I know to Dr. Ngo and Dr. Costello and they all feel the same way after being treated by them… best dentists ever! And they’re the genuinely nicest people you could ever meet. Love ‘em.

This is the best dentist office in the city, hands down! If youre looking for a new dentist or have been putting off a visit, i can’t recomend Dentists on Washington enough.
Dr Ngo and Dr Costello are not only some of the most skilled and professional dentists I’ve ever visited, they are also extremely personable, friendly, and nice. The same goes for the rest of the staff. Being in their office, I never feel like just some other patient. I’m always greeted by my first name and with a handshake.
The doctors have gone out of their way to accommodate my needs, whether it’s figuring out the cheapest payment options and maximizing insurance benefits, to scheduling appointments that work for MY schedule. The doctors even saw me outside of their normal business hours (opened early on a Saturday!) because I had an emergency!
I highly recomend Dentists on Washington, you won’t regret making this your new dentists office.

Everything I wanted to say in my review is covered by other reviewers. All I have to do now is submit these well-​deserved 5 stars.
Wonderful job, Dr. Costello and Dr. Ngo!

I have been seeing Dr. Costello and Dr. Ngo for almost 4 years now. I have followed them to several different offices in that time span-​so you can imagine my excitement when I found out they would be opening their own practice a stones throw from my neighborhood (queen village). The office located on the corner of 6^th and Washington is brand new and easily accessible from anywhere in the city. In addition there is plenty of street parking as well as a large shopping center that I have never had a problem parking in. Like I said the office is brand new with a comfortable waiting room and really pleasant office staff– the staff is also very knowledgeable in regards to my insurance coverage and always explains in detail any questions I have regarding my coverage.
The new office and friendly office staff are certainly pluses, but Dr. Costello and Dr. Ngo are the real reason I won’t need to find a new dental office anytime soon. They each have such great personalities that I actually don’t mind spending 30 or 45 minutes in their chairs. They constantly are making sure that the treatment is comfortable for me and explain the procedure as its taking place. I don’t think I have ever felt an ounce of pain in one of their chairs (maybe I’m just lucky!) and if anything is uncomfortable I just is let them know and they adjust accordingly. I would also highly recommend this office for parents with Children as they seem to be exceptionally good with child patients in my experiences
