Dr. Kostanyan was excellent. I came in with some pretty bad pain in my tooth (whenever I ate) and he performed an examination, a few xrays, and then determine a little work on an old filling might do the trick. Icame home tonight and could eat without pain shooting through my jaw for the first time in months. I'm going back immediately for my cleaning and any follow up procedures that I will need in the future. Very happy with him!

I’ve been a patient of Dr. Kostanyan’s for a few years now and even though i’ve moved out of the area, i still come back to this office for my regular visits. Recently, i waited too long to get my crownput on but Dr. Kostanyan took the time to fit it perfectly. His patience and skill really saved me from a jam. I can’t recommend him enough!

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!

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 doingwith my teeth. I highly recommend him. The front office staff is also stellar.

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!

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 thoroughcleaning 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.

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 DrKostanyan 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 wasbelieved 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!

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 lotof 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.

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 reallyallowed 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.
