Awesome place, everyone is really friendly and helpful. Dr O’Shaughnessy is amazing! I never felt discomfort or pain, and she really looks out for your best interest. I needed (still need a little) a lot of work done, with sub par insurance, it doesn’t break the bank here. I recommend this place to everyone who needs an amazing dentist!

I suffered from an accident that broke my two front teeth and my implant failed from a previous doctor. Dr Vargas worked with me for over a year to restore back my smile. He was patient. He cares tremendously about his patients and it felt like I had a friend guiding me through a difficult treatment plan that involved several surgeries and restorative sessions. The office Manager Michelle was always professional and understanding despite all the hurdles we had to overcome with my treatment plan. For the first time in over 15 years I am able to smile confidently to show my front teeth. It feels surreal to have a perfect smile. Because it’s something I never experienced prior to working with Dr Vargas and his team.

I love Chappaqua Smiles’ new office even more than the last! It is so modern and sparkling clean. I go to Dr. O’Shaugnessy who is by far the best dentist I have ever seen. She is patient, calm, kind, thoughtful — and a perfectionist, which is the perfect quality for dentistry and cosmetic dentistry. My smile looks so amazing, people ask me who my dentist is. Just two weeks ago, Dr. O’ Shaugnessy revised my composite veneers and a friend asked me the next week for the dentist’s number. I recommend highly the doctors, hygienists, and staff at Chappaqua Smiles! Five stars!!

I just became a new client and had my first cleaning. My hygienist was extremely thorough and kept checking in to make sure the discomfort wasn’t too much to handle. Their tools seem very high tech. I had X-rays done and they were able to pull them up on the tv to show everything going on. I asked lots of questions and was delighted by their knowledgeable responses. Dr. Vargas and his team are efficient, kind and talented. 10/10 would recommend.

I’m a 55 year old woman who has been terrified of going to the dentist just about my entire life. In the past I have literally gone 5-8 years between dentists visits . I take very good care of my teeth so there has never been an emergency to go . When I do find a dentist I’m the one who always cancels at least once before I finally go for that cleaning I know I need . The fear is so real and at times I have actually felt like I’m going to pass out !About two years ago my husband made me go to dr. Vargas and I’m now going regularly for the first time in my life!They are all so gentle and considerate, they have managed to make me feel good about going ! I have even had work done , fixing some teeth that were slightly cracked and old fillings needed to be replaced! Would highly recommend! I’m never going anywhere else from now on !

I have being visiting Dr Vargas for a few years now and have always felt comfortable and at ease while here. The staff at Chappaqua Smiles always makes you feel welcome and reassured that they have your best interest at heart. I’ve had a few different procedures done and have been very happy with the results. In addition they inform you of steps you can take to prevent further damage to your teeth, in my case it was a (guard) to prevent grinding. Which was never told to me by previous dentist. Dr. Vargas always explains the options that are available to you which helps you make a logical decision and best choice for your needs/situation. I look forward to having Dr. Vargas and his staff taking care of all my dental needs.May 2023- Recent visit to the new office. It shows the importance that is placed on patient convenience and comfort. I highly recommend Chappaqua Smiles for your dental needs.

I’m always nervous about visiting a dental office but Dr. Vargas made me feel comfortable, it was a painless experience. Dr. Vargas has a lot experience which he funnels into providing the best service to his patients. I highly recommend Dr. Vargas to anyone in need of dental work.

Had a great first experience at CS. They have a beautiful office with great views. We parked right outside (for free! Where does that happen in Westchester?). I only had to wait a few minutes past my appointment time. The hygienist was friendly and thorough, and the Doc was positive, helpful, and quick. For the suggested next steps they are helping sort out the insurance matter, looking forward to my 6 month check-up.

When you see the beautiful smiles on his patients after he completed his work was breathtaking and did bring tears to my eyes. I knew how they felt. You do not feel shame or guilt in his office just hope and happiness that your smile will be as beautiful as his other patients

Arriving at the office of Chappaqua Smiles I received a cordial welcome and immediately met with Dr. Vargas! Films were taken and within a few minutes Dr. Vargas returned and gave a very clear and concise evaluation of the X Rays! The Dr. and I had a lengthy discussion of what he saw on the films and what corrective measures might be undertaken! Given three treatment options, I left the office relieved and much more knowledgeable! First visit was very pleasant and rewarding!

I like the front staff and Dr. Vargas. I have always had problems with my teeth and my husband is never happy when problems end up costing over what the insurance covers. I was so disappointed when I heard that all my Xrays and all my issues had been chatted about and laughed about when my husband was in last, considering it had been an issue between the two of us about “how much my teeth have cost him”. Professionalism does include keeping someone’s files private whether they are married or not. I like the hygienist but our whole family finds she is quite heavy handed and none of us come out of there saying how gentle she is. I still believe they do a good job, but we are going to try a new dentist this year. Sorry

Dr. Lara was very reassuring and made a couple of recommendations.I trust her opinion. In addition, my daughter goes for dental care to Chappaqua Smiles and is very happy too. The office follows covid safety rules so I was comfortable going there. The staff in the office was friendly and courteous. All around a very good experience.Just had another visit and tooth cleaning (after a year and a half!) As before, my visit was great. The hygenist Calila(sp?) was very thoroughand understanding and I will be going back again in July for some minor work. Very nice staff and Dr. Lara is very easy to communicate with and very professional. Highly recommend .Still very happy with everyone I come into contact with at Chappaqua Smiles.Just had another cleaning-very thorough. All the staff very nice and helpful.

We drove from 3 hours away to see him, and it was well worth our time. I truly feel like he cares about his patients and the outcome of his care. I would highly recommend him to anyone… Even with a long drive! ?Update: I just had my final appointment with Dr. Vargas and the case for my implant was placed. It looks amazing! I can’t tell the difference between the implant and my other teeth. I am incredibly happy with how it turned out! ?

I highly recommend Chappaqua Smiles and wouldn’t go anywhere else. Every visit is nice, believe it or not. Everybody is so friendly. You can tell how skilled and precise the doctors and hygienists are. Odd, but an enjoyable experience and always leave happy with better teeth.

My experience at Chappaqua Smiles has been life changing. Before I went to Chappaqua Smiles, I had severe gum recession from teeth grinding that I did not even know about. I also was not happy with how my teeth had started to become crooked, but did not know what to do about it. With in my first few visits at Chappaqua Smiles, I had all of my problems addressed and solved (or at least on a path to a solution). Dr. Vargas is absolutely outstanding, and so is his staff and the office environment in general. Dr. Vargas has the best personality; so friendly, funny, and makes you feel totally at ease and confident that everything will turn out great. With his suggestion, I went ahead with 8 months of Invisalign. My teeth came out fantastic! They are not only perfectly straight, but also white and bright. At the end of the treatment, there was one tooth I was still unhappy with. Dr. Vargas had an instant solution to fix the look of the tooth with bonding. The results were a perfect smile. I couldn’t be happier with Chappaqua Smiles and I would highly recommend it to anyone looking for anything from a simple cleaning to a complicated treatment!

Drove all the way here, had to wait outside of the office. I let the receptionist know that I have a condition and a note from my doctor that I won’t be wearing a mask. They would not allow me in the building, so I cancelled my appointment and will no longer be a client of the firm. Also this firm is infamous for jacking up the bills, happened to me and to my sister. I will go support another business instead of this place.

I went here to today for the first time because my dentist of 23 years does not accept my new insurance. I was so impressed with everyone in this office. They were all friendly and helpful, and my hygienist Diane who did the cleaning was so knowledgeable. Apparently I have been flossing incorrectly, but no one else ever taught me properly! She educated me as she cleaned, and she took before and after pictures to emphasize where I need to focus during my oral care routine. I absolutely recommend this office.

My husband and I just switched to Dr. Vargas because our dentist retired. I am very anxious about going to the dentist, but Dr. Vargas and the entire staff made me feel at ease. They couldn’t be nicer!!! We also feel he is very skilled and competent. We both highly recommend him.
Dr. O’Schnaugessey has an attention to detail like no other dentist I’ve been to, and I’ve had a lifetime of various issues that cause me to grip the arms of the dental chair to a point it has always been noticed. Dr O’Schaugnessey doesn’t settle for less than perfection in her work. She continuously kept me informed all through the process at each visit. She corrected several issues I had, including one tooth where her fix gave me a new quality of life. Not only am I back to 100%, but my teeth have nice new fillings that are unnoticeable.

I was having problems with a crown, called the office in the morning, and had it repaired 15 minutes later! Both of the dentists are friendly and do great work. Their staff is also a pleasure to deal with.

Dr Vargas and his excellent staff make dental care Something of a pleasure instead of a fear.Let’s face it no one “likes “ going to the dentist but it’s really hard not to enjoy the experience here.Dr. Vargas and hygienist Diane are the consummate professionals but more than that they are truly caring and compassionate. I couldn’t recommend them more highly!Dr. Eric Karle

The staff at chappaqua Smiles is always very friendly, courteous and professional. They always run in time – I can’t remember a time I have had to wait more than 5 minutes for my appointment. Dr. Vargas is so nice and reassuring and makes me feel confident about any procedure I might have to undergo. As the staff there knows, I am pretty phobic about going to the dentist, even for a cleaning, but they ease my anxieties every time. I highly recommend them!

I truly love everything about this dental office. It all begins with Michele and Jamie at the front desk who always greet you with a warm smile and assist in making appointments that fit my schedule. Everyone from the awesome hygienists, Debbie and Diane, to the dental assistants are reassuring and efficient. Dr. Vargas is an amazing dentist. One of my favorite things about him is that he communicates about all that needs to be done and what he is doing at the time the dental work occurs. Dentist visits can be stressful but Chappaqua Smiles does everything in their power to make them less so. I highly recommend this office.

The staff was exceptionally friendly as soon as I walked in the door. Diane, my hygienist, was incredibly efficient and super knowledgeable. Dr. Vargas is wonderful and genuine. I’m glad to have found such an awesome dental group nearby.

I had a crown installed today and my bite feels perfect! Such positive experiences at this office — no wait time, easy to make appointments, plenty of parking (front on the street and in the back), clean & modern space. The office staff is helpful and friendly. My cleaning with the hygienist was thorough without being painful. And both dentists have exceeded my expectations.

Everyone I’ve dealt with at Chappaqua Smiles is professional and friendly. They take the time to get to know their patients. From the greeting you get when you enter, from the hygienists to Dr Vargas himself, you feel comfortable the moment you become a patient. Dr. Vargas is knowledgeable and takes the time to explain things. The hygienists go out of their way to ensure your experience is as relaxed and easy as possible. Best dental care I’ve ever received.

Dr. Vargas is friendly, caring, and involved. I would highly recommend.
