Had a great experience! I am a registered nurse and hold a pretty high standard for bedside manner. The whole visit I felt so comfortable, they talked me through every step of what they were doing and were all very friendly.Also it was the least painful teeth cleaning I have ever had (thanks Julia!) definitely would recommend this dentist to anyone looking for a good dental experience.

I really enjoyed this experience (as much as you could enjoy the dentist!) She pointed out some potential cavities, but didn't push at all that they be filled, instead suggesting I contact my previous dentist for old x-rays so she cansee how the cavities have changed and then determine if they need to be treated. This was a really nice change vs. some dentists I've seen in the past who push hard to get you to pay for more things. I really trusted the folks at this place, and this will definitely be my dentist for the rest of my time in New York!

So I'm a huge periodontal slacker and haven't seen a dentist in 5+ years. I went in knowing I'd need to have some follow up visits but didn't realize I'd be so excited to get everything back on track. This officeis wonderful. Julia, my hygienist, was so so so nice and took great care in making sure I was comfortable and knew everything to expect. Dr. Koster was also amazing. I had one dentist consistently from the age of 4-24 (which I think is why I've lacked the motivation to find another one - switching doctors is hard) -- but I fully feel like I've found my dentist in NYC! She has an amazing bedside manner and also takes the time to explain everything!

I got my teeth cleaned here twice, the first time was fine, the second time i noticed that my teeth looked funny, they were cleaning in between then and must have done so to roughly, now the marks are there. Ihad beautiful stain free teeth and now i noticed discoloration, like they scraped too much or too hard. Don't really like the service here, I'll be looking for a new dentist. They also did a bunch of x rays for no reason.

First time patient at Gramercy Smile and I had a great experience. There was a schedule change from my initial appointment but the staff called and we were able to work out a time that I was still within my schedule.I waited for less than 5 minutes after I filled out my forms. Got my x-Rays and cleaning. Dental Hygienist (her name eludes me) was very thorough and checked if i was okay every few minutes. I was fine but guess I looked nervous since I'm not a fan of the noise. Doctor Koster was very thorough as well and explained everything on my X-Rays and recommendations on cleaning and things to be mindful of to maintain my teeth's health. Definitely recommend to others.

The service was great. I was 10 minutes late, they whisked me away and got me started with X-Rays. The hygenist was fantastic. The dentist I had met with went over my X-Rays and explained everything to me. I mentioned Ihad some pain and she took the time to investigate. Really great dentist, I'm very please and will continue coming back :).

Adrianne Koster herself is incredibly pleasant however the hygienist doing my cleaning was a little rough. During the cleaning, she kept hitting my gums (though I understand happens) but not that frequently. Every time I would flinch she saidthere must be a reason my gums are sensitive, though in the past this hasn't been an issue. I had my original appointment booked and they wanted to push up my time. Then wanted to do the same with my rebooked appointment. Office seems to be a clean but a little run down.

The dentist herself was fine, but the office is incompetent. On this site they incorrectly listed my insurance as accepted (and still do, even after being notified that it's incorrect!) and ran my insurance benefits to the ground. Either theywant people coming in with the wrong insurance so they can run up the bill, or they're incapable of running a business. Even worse, the office manager quoted me on the price for an entire procedure, and after it was done I was told that was the cost for each tooth, and ended up paying triple what I was expecting. No remorse for their mistakes, and this has negatively impacted my dental health, because I can't afford to get the rest of the treatment I need now that my benefits have run out. If I could give zero stars I would.

Ugh, I will never go here again. I wanted a place convenient to work, so I decided to come here. The front desk staff is friendly with the exception of who I am guessing is the desk manager/bookkeeper. She was awful.She kept pressuring me to get all of these different procedures/x-rays/extras, no doubt because they can bill insurance extra. All in all I really did not feel comfortable because of that woman and will not be going back.
