Verified Patient Reviews
I've been going for over a year and everything is good.
Wonderful staff and dentist, I highly recommend!
Was friendly, and answered all questions/ concerns that I had.
Igor is very professional and thorough. Perhaps what I adore most is his compassion and understanding of patients' needs. And since l am not that fond of visiting a dentist his wonderful sense of humor is definitely a plus. The receptionist and technician were exceptionally friendly and welcoming too!
Highly recommend Dr. Kostanyan!
He is gentle, fast and I appreciate that he takes the time to answer questions and actually explain what needs to be done and what should be done next
I always feel secure that I am in good hands. His bedside manner is wonderful. He is a skilled and honest Dr. I have recommended people to this office before, and I will do so again.
Great dentist!!! Highly recommended, saw 3 other dentists, all **** compared to Dr. Kostanyan. For real, that's my honest review and my opinion. Will be back!
Dr. Igor is kind and has a great chair-side manner. He's very skilled. And his Anesthetic shots are among the most gentle I've ever experienced. I've found him to be very upfront: always explaining the process, telling me what he's doing with my teeth. I highly recommend him. The front office staff is also stellar.
Dr. Igor made me feel very comfortable even though I was a nervous wreck. I honestly just felt a pinch and then nothing at all. I am very pleased with the treatment I received, the professionalism of the staff and cleanliness of the facility. I would highly recommend Dr. Igor and the facility for their great service.
Amazing service. One of the best!
Last week, after my semi-annual cleaning, Dr. Kostanyan noticed some tooth decay under a very old filling. He recommended that I have the filling replaced, so I scheduled a followup right away. I came in a week later for the procedure. I had to wait about fifteen extra minutes, but Dr. Kostanyan apologized profusely. He was fast, funny, and friendly. Very professional, and he always made sure I was comfortable. I highly recommend Advanced Gentle Dentistry!
Relieved to have visited a great dentist and had a successful visit!
Great doctor, nice staff, clean modern facility .
Ever have a dentist use floss on you? No? Why not? Dr. K does and it shows his attention to detail. He is efficient, kind, and gentle.
He made me very comfortable, explained everything in a manner that I could understand and I was in and out.
Very pleasant and competent md and office staff. Definitely recommend !
Super knowledgeable and made me feel comfortable. They have a friendly staff, and they assist you right away. Thank you for my cleaning, the girl was amazing.
My initial visit was great. Very professional,comical dialogue,answers questions pertaining to procedure,friendly and no pain. Root canal performed and didnt feel a thing. Great dentist.
Dr. Igor makes the experience of going to a dentist comfortable and great. I left there satisfied and pain free.
Kind, gentle, wonderful!
Great dentist, knows what he's talking about.
My husband and I both go to Kostanyan for all dental appointments. The office is lovely and the receptionist is sweet and works quickly. I only waited about 2 minutes upon my arrival to meet with Kostanyan. He did a thorough cleaning and took his time making sure my teeth were cleaned and x-rayed correctly. He kindly informed me on the importance of adding certain practices into my daily dental routine. He had on some light music in the background that was way more interesting to listen to than the normal elevator music you hear in the dental office. I appreciated Kostanyan's relate-ability, honesty, and thoroughness. I would recommend him to anyone.
He's such a great dentist!! He went step by step with my daughter, when she came in so frightened. And she was so amazed with his questions, she loved it. She actually can't wait to go back. He made sure she was very comfortable which I was so great full for! I extremely recommend!!
He was very easy to talk to and informed me about a few things I hadn't even considered asking which was very helpful. Would definitely recommend Igor and plan to return regularly!
Dr. Igor is the best! I still hate going to the dentist, but he makes it tolerable haha
I have had only one visit so far, but have another appointment and I plan to continue going in the future. I have had a lot of work done over the years by many different dentists in different states and Dr Kostanyan seems very professional, IMO. A little loose and easy going, but not too loose, very personable and very capable with a firm grasp of the tools. They say you can trust a person who works with his hands and surprise, I do. The support staff also seemed very pleasant and not disgruntled. Thanks ZocDoc and Dr Kostanyan.
I was quite nervous going back to the dentist, since I didn't have good experiences with the last dentist I went to long ago, but Dr. Igor was very calm and casual so I felt at ease. He addressed what was believed to be the root of my tooth pain (no pun intended) and got started right away. I'm very happy, and wish I had went to this office years ago!
Dr. Kostanyan was great! I had some dental problems he was gentle and sensitive to my issues. I would highly recommend him.
I was ushered in to see Dr. Igor immediately after I arrived - having already filled out all the usual paperwork on Zocdoc the night before. I want to point out that this is often not the case with a lot of doctors and specialists around Park Slope. At other clinics, I've been kept waiting for more than an hour at times. As such, this was a pleasant surprise! Dr. Igor was very friendly, knowledgable, and patient. He quickly figured out the root cause of my multiple tooth problems for the past few years (dry mouth caused by my chronic pain medication, leading to tooth decay due to the lack of saliva production). I needed a complicated filling done, and he was extremely gentle throughout the process, often checking to ensure I felt comfortable. The work he did on my tooth was excellent! It looks like a brand new tooth. You can't even tell there's a filling on one side because it looks so seamless.
Dr. Kostanyan is a great dentist. He is efficient and thorough with both his description of a treatment and in his work. He also maintains a nice balance between being professional and personable. I would recommend him to any one looking for a new dentist!
I finally found my dentist! Dr. Kostanyan was straight forward and really awesome! He did an amazing cleaning, and after took x-rays so that we could see how my teeth looked after the cleaning rather than prior too. Doing this really allowed us both to see if any work needed to be done or not. Most dentists will do x-rays prior to a cleaning, when your teeth are at their worst really, and then try to tell you about all the work you may need. Anyway. Very professional, kind, and funny. Took me in right away.
Was just there for a checkup. Clean office, short wait time, great bedside manner. I'd recommend Dr. Kostanyan to anyone looking for a quick and easy checkup.
It was a good experience. My teeth were in good condition and just needed cleaning. He did a quick cleaning and gave me a toothbrush and toothpaste. Gentle doctor since I am a low-tolerance of pain and I recommend him to everyone.
He's amazing and so are the staff!
Great dentist. He was personable, very professional, and my teeth look great. I got a regular clean but I had a lot of bleeding from gum disease. Dr Kostanya. Knew exactly what to do.
He is a great dentist
He was excellent.
Igor is the BEST!!
I was amazed by the punctuality. As soon as I walked in, I didn't even have to sign in and wait, I was asked to come right in and the Doctor immediately started working on my teeth. The doctor's bedside manner was perfect. He gave me a thorough cleaning and addressed the next steps we ought to proceed with on follow-up visits. I will be returning to his office without hesitation knowing that I would be treated with the care and attention we all look forward to.
Wonder ... I will see what I can do about getting another root canal !!!
It was a nice experience... He was very pleasant and had a wonderful disposition and sense of humor .... Can't wait until I go back next week for my root canal and my noose :D
Very happy with my visit and the doctor. He is friendly and concerned. Office staff are also very kind. The doctor gave me helpful information and did a thorough cleaning. Would highly recommend!
Dr Kostanyan was very thorough and attentive. I have a lot of anxiety at dental appointments and he dealt with it very well. I highly recommend !
Excellent establishment, professional and thorough teeth cleaning. Wise and upfront tooth care advice. No crowding and no excessive waiting. Highly recommended.
I hate the dentist, he was cool, I felt comfortable.
As someone who continues to have anxiety about visits to the dentist, I am especially thankful for Dr. Kostanyan. As he cleans my teeth and goes over procedures with me, he checks in constantly to make sure I'm okay and that I understand what he's doing and why. I can't recommend this dentist enough.
Very nice dentist. Didn't try to up sell me on additional services like so many others have. I appreciated his honesty.
Dr. Kostanyan was very knowledgeable and gave great advice about my condition. I always felt respected and comfortable and he was very personable. There was no wait time and I would highly recommend the office to friends.
I have never been to a dentist where the whole staff make me feel welcome, comfortable, and at ease. Like the next guy, going to the dentist makes me nervous, but Dr. Kostanyan and his staff are incredible about making the experience more than pleasant. Great team! I am sending my whole family!
He was really thorough, took his time and explained me everything. He reviewed the x-rays with me and he made sure I was comfortable and even asked me if I needed a break. I'm glad I found this dentist!
I was seen immediately after completing initial paperwork. The doctor was polite and professional and I was on my way all within an hour. Definitely recommended!
Generally great, but he was a little rough. I hadn't been to the dentist in a while, so maybe it hurt because of that, but it was the most painful cleaning I've received! He was very nice. Staff not so helpful or friendly.
He is very professional, knowledgeable, and kind to his patients. He is the top.
My visit with Dr Igor Kostanyan was one of my best experiences EVER, from the friendly & knowledgeable reception to me going in at the time of my appointment (Not 30min - 1hr after the scheduled time) to the care Igor puts behind his decisions. I was also very impressed with Igor's Needle to the gum technique, because it was the smoothest novocaine shots I ever had, and I've had my share. My follow up visit went just as smooth and I am happy to call Igor my New Dentist.
Very friendly and professional. Hardly had to wait at all and the receptionists helped with my insurance questions. He explained everything he was doing and there was very little discomfort. In and out very quickly.
Always the best!!!
Very professional. Igor knows what he is doing, and he treated my situation with urgency so that I can improve my dental condition.
Great experience! Quick visit. He really cares about your comfort. Great cleaning. I was out in a matter of minutes.
The office staff was very friendly the appointments were very much on time and the doctor had excellent bedside manner. I felt comfortable and I felt like I was being appreciated as a patient the entire way through. Thorough and to the point.
So clean! So timely! So thorough! LOVE this practice!
Excellent dentist! Highly recommend.
It was great! He was kind and always made sure everything was okay.
I have seen him on several occasions by now and this is my first dental experience that hasn't been subpar and lousy. Definitely staying with this practice!
He does a fantastic job. He is thorough in his work, while also communicating throughout the process, and taking management of pain/discomfort very seriously. I found my dentist.
Very nice person. Minimal pain. Fast.
As per usual I'm always a complete mess before hand. When's he's done all I want to do is hug him. Such a great dentist!!!
Great doctor! Very good cleaning and communicated my next steps to me. My new dentist!
This was my girls first visit to the dentist & they had an amazing experience! Highly recommended dentist ??. He is wonderful with adults & children on all levels!
I would highly recommend Igor! He is extremely professional, super attentive, and most importantly does a great job!
The doctor was kind and professional and give me good assurance and was gentle. Thanks for the service
Great service, gentle and patient...great at calming my nerves...
Great. Very competent and professional.
What can I say he's the best by far!!!!
Very good dentist, would recommend.
I had a routine cleaning scheduled for myself and my twin 6 year old girls. Doctor Kostanyan not only brought us all back to the room but also did the entire cleaning himself. One of my daughters was extremely nervous and his easy-going, gentle manner put her at ease. I am new to the practice and cannot recommend it enough- from the friendly front office staff to the caring doctor- everything about this practice is amazing.
He is wonderful, knowledgeable and made me feel totally at ease (which is not easy- I'm super fearful when it comes to dentistry!) I recommend him wholeheartedly!
I walked in on a Friday afternoon with a terrible toothache, when none of other dentists I contacted were available and was treated like the most important patient. Dr. Kostanyan is amazing and I feel very fortunate to find him by chance!
He was very nice and took his time to see how I was feeling. And office is clean n neat n the helper was nice to.
Dr. Igor is an amazing dentist. He was so caring and concerned about my comfort throughout the entire visit. I will definitely continue with him as my dentist.
Great visit. Staff is very friendly.
Made me feel at ease !!!
The front office is kind, efficient and welcoming. Dr. Igor CARES. Excellent bedside manner. He's had many dental procedures himself so he knows what you might feel. This makes a huge difference. He doesn't just dive in. He waits for the Novocain to work. He asks how you are doing. Dr. Igor performed my initial teeth cleaning himself and then spoke with me about the problems: 3 fillings and a cap. Ya, it had been a while. But it had been so long because I didn't want to go back to my original dentist who had a bad bed side manner. My follow up appointments we booked quickly and for the days I wanted. Very accommodating. I did a lot of research and Dr. Igor Kostanynan was highly rated. I add my 5 stars as well. I had such a great experience, my husband (who really does not like dentists) asked for an appointment. Thank you, Dr. Ivan.
Kind and courteous, very personable.
Absolutely wonderful! and after 10 years of failing my dental health, he put my teeth back together again with minimal pain. He also made me laugh the whole time. :)
Dr. Igor was an efficient and thorough dentist. I would recommend him to my friends / fam.
really great guy
Best cleaning I ever got. I love my German dentists but he really did a better job. Very professional!
Unbelievably kind. It had been quite a while since I'd been in for a cleaning (marriage, move, kids, etc.) and he was totally sympathetic and understanding. I've had dentists be extremely rude, so while he gave it to me straight, it was with sincere compassion.
Great Dentist. Glad I found Him . Thanks Guys
He was great. Very friendly and personable - but to the point, I got in and out in 30 minutes. No annoying upselling, he gave it to me straight. Dr. Igor did the entire exam and cleaning - no dental hygienist. I will absolutely go back and recommend him, best dentist visit I've had for a long time.
The exam and cleaning were quick, yet thorough. I had a long wait time due to an emergency. However, a hygienist was able to jump in to reduce my wait time.
Thorough and professional. I felt very comfortable with him. Will definately go back again. Front desk staff were friendly too.
Great! Very pleased.
Would recommend to anyone who wants to be served with care and concern.
