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

I hadn’t gone to the dentist in three years due to not having dental insurance. I am also someone who is typically very wary of and nervous to go to the dentist. Dr. Harris, Skye, Rachel, and Ashley all made me feel so comfortable. They answered all of my questions about procedures, cost, and next steps. I love that they have pictures of themselves up as they are covered in PPE (for obvious reasons 🙂 –this helped me to feel more at ease. They did not move forward with any procedure before informing me of the cost, which I really appreciated. I would highly recommend Dr. Harris and the team!

Dr. Harris was very compassionate and caring. She was gentle and explained every step before acting, which helped keep me at ease during the procedures. Her pricing is very reasonable, and she accepted both types of insurance I had and took me as a new patient. She is very knowledgable and skilled in her art!

I’ve been in Philly for over 6 years – and I’ve finally found a great dental office! I’ve been searching for a dentist like Dr. Harris. Her and her staff – Kathy, Skye and Rachel are all amazing. I have had dental issues all my life (hence, why I hate going to the dentist: because it’s always bad news!) However everyone here has put me at ease – they are not only gentle (I’m 33 but have the teeth of an 89 year old from the middle ages!) but also thorough, super efficient with time (we all have work schedules people!) and honest. I have dental insurance – it doesn’t cover too much – and they were able to work with me financially about pricing for some procedures I needed to get done – I super appreciate that. Now to the really good stuff! Every room has windows and a great view (something that REALLY helps my emotional state while I’m sitting there getting my teeth drilled – painlessly I might add!) Everything is up to date, it feels like a personal experience, and again, I can’t stress this more – I TRUST them. That’s huge for me and it should be for everyone else too. I really think if you’re looking for a dentist (or want to switch because you feel you’re not getting the best treatment) visit Dr. Harris. FYI, I only want to write on Yelp when I have great experiences, and this is one of them. Your teeth are important folks – and having a personal, caring dental visit means a lot to me – so check them out. If not – better time slots for me!

Nancy R. from San Francisco, CA (Source: Yelp)


I’ve gone to Dr. Harris for dental work and to Rachel for cleanings for approximately four years and have always had very positive experiences there (despite the reality of “going to the dentist!”). They are thorough, friendly, work hard, and explain what they’re doing (and why). Recently, I had terrible sudden gum/tooth pain and they “got me in” that day. They weren’t sure which tooth (of two) was causing the problem and immediately got me into an office that does root canals. I was (and am) so thankful that they did all this so efficiently and nicely as I was not in good shape. AND, Dr. Harris gave me her cell number in case I needed anything. Ashley is great too…so efficient and so friendly; she thinks of things before you do!

Dr. Harris, Rachel and the whole Smiles on the Square team are always such a fantastic and friendly staff. They provide great dental services in Center City – I can’t recommend enough! I have been a patient since 2015 and they have always been informative, well priced and great with all dental procedures and cleanings.

Jeff B. from Philadelphia, PA (Source: Yelp)


Nancy Harris is the best dentist in the city, hands down. I needed a new night time mouth guard, and Dr. Harris created me one that has fit perfectly  and worked great for several years now. Her staff is friendly and it’s easy to get an appointment that fits around your work schedule. I’ve recommended Dr. Harris’ practice to several of my coworkers, and they have all had positive experiences as well.

Gary R. from Philadelphia, PA (Source: Yelp)


I went to Dr. Harris’s office because I was looking to get my teeth cleaned and whitened before our wedding.  It was very easy to get an appointment for a time that fit my schedule, the staff was extremely professional and friendly, and the end result was fantastic.  My fiance wound up going to Dr. Harris’s office shortly after since my teeth turned out so well and the experience was so easy.  Highly recommend.

Have been going to Dr. Harris for about five years now – even though I’ve lived in London and NYC for part of it! Lovely office and staff so it’s been worth it to make a pit stop in Philly twice a year to see them. I consider Rachel a friend at this point and look forward to our visits! Highly recommend this office

Christina Blake (Source: Google)


Over a decade ago I got into an accident that knocked out several of my front teeth. Dr. Harris and her team rebuilt my smile and I’ve been going here for all of my dental work ever since. The whole team – Dr. Harris, Rachel, Skye, and Ashley – are all friendly and my appointments are always on time. The office is also really convenient because there’s an endodontist in the same building. During one visit we found that I had a root canal infection – Dr. Harris worked with the endodontist to get me downstairs for an immediate root canal and then right back upstairs for new crown fitting and a temporary crown – they basically resolved everything in an afternoon where if it was another office we could have had to schedule multiple appointments across days.

Tim M. from Philadelphia, PA (Source: Yelp)


Like most I’ve never been very fond of trips to the dentist, and while that is still the case, I will say that my experiences with Dr. Harris have been very pleasant. I’ve had to have two root canals (performed by an outside specialist) and a variety of other dental work done over the past six months. Each of my visits to Dr Harris’s office has been quick (I’ve never waited more than a moment or two in the waiting room) and relatively painless (the staff is exceedingly welcoming). Of course dental work is never a great time, but this office makes it as convenient as possible, and has never been anything but accommodating. Highly recommended.

Frank B. from Philadelphia, PA (Source: Yelp)


I have been a long time patient of Dr. Harris…it’s been about 10 years now. The atmosphere in the office is very professional. I am very happy with the service I have received over the years. I would definitely recommend anyone who is looking for a great dentist to contact Dr. Nancy Harris…she truly cares about the wellness of her patients, you will not be disappointed.

After putting off dental visits for too long I started going to Dr. Harris. She and her staff have been wonderful. They created a long term treatment plan based on my needs and my insurance. They’re always available to answer questions and I always know what my costs are for the work being done. Everyone is friendly and knowledgeable and Ashley at the front desk has really taken a lot of the stress and anxiety out of the process.

Diana P. from Philadelphia, PA (Source: Yelp)


I have been a long time patient of Dr Nancy Harris and I am very pleased with the service and professionalism I have received over the years. I had veneers placed over three years ago and they look amazing. The staff is welcoming and always so nice. I feel very comfortable and at home in this office which I sure is surprising because its a  dental office but I actually look forward to going and getting my teeth cleaned. If your looking for a dentist I highly recommend Dr Nancy Harris!

Mary H. from Philadelphia, PA (Source: Yelp)


This is the Dentist office everyone should go to, Dr Harris is very professional and made me feel very comfortable at my appointment.. I must admit at first I was scared, but by the time I left, I was so at ease. The staff made me feel at home, they were very professional down to earth went out of there way to ease my fears. I highly recommend Dr Harris and her staff for your next dental appointment.

Maire N. from Philadelphia, PA (Source: Yelp)


I was very afraid of going to the dentist. I put it off for ages while I tried to get the nerve to make an appointment with a new dentist after moving to the Philadelphia area. I finally found Dr. Harris and made an appointment, and I will be looking no further in my quest for a dentist that I can go to without fear. She and her staff were absolutely wonderful; they were friendly, kind, and completely understanding of my fear. They made me feel very comfortable and took the time to explain things to me. If you are looking for a dentist in the Philadelphia area, this is absolutely the place to go, especially if you have any anxiety around going to the dentist like I do!

Victoria K. from Philadelphia, PA (Source: Yelp)


I love the whole office! Very clean, stress-free environment. Ashley at the front desk offers to call my insurance for me (!) and remembers me when I call. Rachel the hygienist is so friendly and laughs at my jokes. Most importantly, she is also straightforward and honest with regards to my teeth and gums. I really appreciate her direct approach! At the end Dr. Harris will pop in for a few minutes to take a final look.

Robert B. from Philadelphia, PA (Source: Yelp)


I wrote this review before, and for some reason its “not currently recommended.” I’m a real consumer, not associated with Dr. Harris or anyone in her office in any way (except as a customer) Very professional and well-managed office. Dr. Harris is careful, thorough and friendly. The hygienists are well trained and highly competent. The reception is welcoming and the record keeping is excellent. The practice is very clear on charges and insurance coverages. If your insurance covers Dr. Harris, it would be a mistake not to try her. I’ve been a patient for over 10 years and am highly satisfied.

Jim Weiner (Source: Google)


Dr Harris and her staff were very professional and had me checked in and seen in a very timely manner. I appreciated Dr. Harris’ candor and recommendation for treatment. As this was my initial visit with Dr. Harris, I was impressed and extremely satisfied with the services rendered and would not hesitate in making future appointments with Dr. Harris and her staff.

Monica Truelove-Hill (Source: Google)


I absolutely love Dr. Harris and her team (Skye, Rachel, & Ashley)! They are all very friendly and make you feel completely at ease, no matter the procedure. The office is clean, scheduling is so on point that I’ve never waited longer than 5 minutes, and everyone is professional and kind. The quality of their work is excellent. They’re very transparent about your dental health and care plan. I’ve never had a bad experience here. I can’t recommend them highly enough!

Johnny P. from San Francisco, CA (Source: Yelp)


Doctor Nancy Harris and her staff are a first rate dental practice. From the moment you enter her office and are greeted by Ashley at reception the personal touch and caring concern you receive make for a wonderful experience. Ashley is very well versed in navigating insurance plan regulations and does so with a smile. Once you are taken in to the treatment area you will find it spotless clean. Her diagnostic tools and equipment are all state of the art. Doctor Harris and her assistant, Skylar, work very well together. As you undergo procedures, each of them take a moment to explain exactly what will be done, and inform you to raise your hand if at any time or for any reason you are feeling any distress. The staff and Doctor Harris make the typically difficult experience of having dental work done very easy to endure. I highly recommend you entrust your mouth, teeth and gums to Doctor Harris and her staff !

Kevin D. from Philadelphia, PA (Source: Yelp)


Dr Nancy Harris and her staff are top notch.  Having chipped my front tooth as a child, Dr. Harris has repaired the molding and crown twice now (during visits almost 4 years apart). I have been extremely satisfied with the results each time. Each interaction was very efficient, professional, and pleasant.  No one is really fond of going to the dentist but I actually look forward to it now.  I highly recommend them.

Abby C. from Wayne, PA (Source: Yelp)


This is the first time I’ve ever actually liked going to the dentist. I made an appointment a few months ago after I managed to avoid the dentist for about two years, so I wasn’t surprised when I was told I had some periodontal issues and a few cavities. One of those cavities ended up being a root canal, so I spend quite a bit of time in the office, probably 6+ appointments in six months. They are so nice! Dr. Harris always explains what she’s doing very clearly, and Rachel (the hygienist) is straightforward and easy to talk to. Ashley at the front desk deals with all the insurance and billing issues super easily. My favorite part is their ability to combine appointments, such as scaling and root planing on one side of my mouth + filling cavities on the same side so I only have to get numb once, or putting on a crown and having a periodontal check at the same appointment. It’s easy, efficient, and comfortable.

I love Smiles At The Square! I’ve been a patient there for a few years, and when I have an appointment, I feel like I’m visiting with friends, which is high praise since I’m not a fan of dental work. The entire staff is friendly and easygoing, the office is clean, and service is timely and hospitable. They have everything you could want from a dental practice!

Christian Perucho (Source: Google)


Fantastic experience at this office! I came in as a new patient, and the service was wonderful. Check in and paperwork with Ashley, the office manager, was quick and streamlined, and I did not have to wait for very long (if at all) to be seen. Office is clean and spacious, with a great view of the city right from the exam chair. Dr. Harris and her dental assistant Skye were very friendly and knowledgeable, taking their time to explain each step of what they were doing throughout my exam and cleaning. Of note, the office has a very thorough COVID-19 protocol, and I was screened (both with a temperature check and a symptom attestation form) immediately upon arrival to the office. Staff members were wearing the appropriate PPE during my entire visit, so I felt very safe! Happy to be a new patient at this practice, and I would highly recommend their services to those looking for a safe and inviting place to receive their dental care – thank you Dr. Harris, Skye, and Ashley!

My wife and I have been going to Nancy Harris for almost 3 years now and we’ve had great experiences during our visits.  I would recommend the office to anyone looking for a convenient, clean, experienced practice in Center City.  They always give me a call the week of my appointment as a reminder and have always accommodated my schedule if I’ve needed to change dates and times

I feel very fortunate to have found Dr Nancy Harris and her highly professional staff after moving to Philadelphia 2 years ago. My cosmetic procedure resulted in beautiful and natural looking veneers just in time for our son’s wedding! I couldn’t be happier! A very positive dental experience thanks to Dr Harris and all of her staff.

Lauren R. from Philadelphia, PA (Source: Yelp)


I used to be so afraid of the dentist until i found Nancy. She is the absolute best. Since I have been going to her i’ve had multiple cavities filled, cleanings, and i could’t be happier. Honestly i don’t know what I would have done without her & her staff because every other dentist either killed me, screwed my teeth up, too expensive and some just were just not nice. Everyone in Nancy’s office are always incredibly nice, they make you feel so comfortable. I would be a walking billboard for her and her team. Trust me i hated the thought of going to the dentist now I love to go. So thankful for them. I recommend her to everyone! My whole family even goes there now. Nancy Harris is by far the best.

Nathan K. from Ambler, PA (Source: Yelp)


I knocked out my top 4 teeth in a weightlifting accident 20 years ago (yikes!!). After having 1 of the 4 teeth pulled, putting in a temp bridge and then putting in the permanent bridge, 20 years later the bridge is still in and no one has a clue, which is imperative as an entertainer not to have an audience fixated on what I know are not my actual teeth. So the job is perfect…it looks great and stayed in place. I’ve been going for routine visits every 6 months and the attention to detail is really good (always gently reminding me what to do). A great practice.

Rachel has been cleaning my teeth for over 8 years now and has been absolutely terrific. She’s kind, professional, thorough and always makes sure you are as comfortable as possible. I’ve never had to wait while there- my appointments are always on time as scheduled. Thanks, Rachel!

Kathy Perini (Source: Google)


Dr Harris has been my dentist, and Rachael, hygienist extraordinaire, for many years. They are a caring practice and were even able to help a family member for an emergency cap when they arrived in Philly for a wedding and cracked the front tooth while traveling here (pre-pandemic) Smiles at the Square is an awesome practice!

Arthur P. from Cherry Hill, NJ (Source: Yelp)


Having known .Dr. Harris since her practice began, all our family have been under her care. We have always found she and her staff to be extremely professional and caring. She uses the latest technology to achieve the best results .She is always available when we need emergency treatment. The staff has always been kind and reassuring and a pleasure to be with.

Jennifer B. from Philadelphia, PA (Source: Yelp)


I was searching for a new dentist close to my job and a co-worker recommended Dr. Harris. I could not be happier with that recommendation!! Dr. Harris made getting a root canal painless. I’ve also gotten a fantastic cleaning and my teeth whitened. I can officially say I have star-quality smile all thanks to the team at Dr. Harris’ office!

Morgan Gilbreath (Source: Facebook)


I recommend this dental office to everyone I talk to. Not only are they extremely kind, personable, organized, and professional – they have truly SAVED my teeth. My previous dentist was not very attentive with my many dental issues (I am a terrible night tooth-grinder with very soft, cavity-prone teeth). Dr. Harris & team fixed up all my problems and stayed on top of them so that over time, my teeth have become much healthier! I cannot thank them enough for all that they have done for me.

I was very nervous about finding a new dentist after going to the same one for 14+ years and I am so happy I found this practice. Dr. Harris and the entire staff are incredibly kind, patient, and knowledgeable. My appointments have gone smoothly and quickly. I’m not nervous about going to the dentist anymore! Highly recommend!

Eric H. from Philadelphia, PA (Source: Yelp)
