I made an Apt for both my sons after many other attempts at other pediatric dentist and ALL were fails!!! Dr. Greco was better then AMAZING ! Her patience was outstanding she let them help with the process of the Cleanings and told them every detail about what she was doing! Not one tear from my kids ALL smiles and even gave Dr. Greco hugs after !!! Now if that doesn’t say AMAZING dentist I do not know what does ! Hands down 10 Stars if I could !

I literally walked from the reception area to the chair to have my x-rays taken upon walking in the office. Once done with my scans, it was a short wait until Dr.Greco came in. Not before being greeted by Dr.Shaffer who looked over my scans and talked cars with me. He briefed Dr.Greco on what he saw as she finished up her previous patient. All in all, this was the most pleasant visit I’ve had at any doctors office. Highly recommend you use their practice.

Dr Greco and Dr Shaffer in my opinion are the best around. I’ve been to dental offices that don’t really have your best interest at heart but these two doctors are the exception to the rule. Not only are they awesome but they provide you with excellent service. I recommend highly above any other dentists out there.

Gina B. from Long Island, NY (Source: Yelp)


I’ve been coming here since shortly after the office opened. I have nothing but positive things to say, the office has flexible hours including a late night which is super convenient. The office is clean with up-to-date equipment and the staff is so incredibly friendly. Dr. Greco is super gentle , thorough and I actually look forward to my visits ( which thankfully aren’t frequent)

I called Polished Dental for tooth pain and ended up needing an Emergency Root Canal. It was not only pain free, but a relatively comfortable procedure. The next day I felt like no work was done. This was so much better than my prior experience with a root canal at my now ex-dentist. I was very nervous to go to the dentist during the Covid pandemic – Dr. Lauren Greco and her partner Dr. Michael Shaffer made me feel very comfortable and safe! Polished Dental is a great practice that I would highly recommend.

Visited Dr. Greco on 03/08/18 around 7pm, I was the last patient. I can’t thank her enough for her patience and professionalism, it’s was so refreshing to visit a dentist office that was so accommodating and they made sure I left their office very happy! I initial went in to fix my chipped front tooth, that a previous dentist ‘patched up’. Dr. Greco made sure I left her office very satisfied. She had redone my filling and it was sooo perfect, I couldn’t even tell I had a filling on my front!!! Finally found my new dental office 🙂

Dr. Greco and Dr. Shaffer are both incredibly skilled, gentle and caring professionals. Prior to finding this practice I was terrified to go to the dentist. Now I actually look forward to my 6 month check up and cleanings. Dr. Greco is incredibly gentle! I also had extensive dental work with this practice and my teeth came out perfect! Dr. Greco is a gem! In fact, I trust Dr. Greco to take care of my children’s teeth as well! I highly recommend this practice to anyone and everyone!

I can’t say enough about how pleased I am with Polished Dental Care! I was never a big fan of going to the dentist, but Dr. Greco makes it an enjoyable, pain-free experience. The staff and the dentists are all professional, caring, and honest, and they keep their appointments on schedule. It is obvious that their first priority is providing exceptional experiences, and not increasing their bottom line. I highly recommend them!

Edward Obligenhart (Source: Google)


Every time I come here my whole scheduled procedure goes down without a hitch! I am seated right on time or sometimes even a few minutes early (which I prefer in this busy world we live in) and rescheduling for follow ups is always attended to in a professional matter! No hassle. Lauren (my dentist) is sweet and knows how to keep a cheerful conversation through your process and always remembers our individual conversations for the next time you come, if she can make somebody feel this special imagine what she can do for your teeth! Thank you guys for all your help and service. I am already scheduled to return 🙂

Tim G. from Amityville, NY (Source: Yelp)


Me and my fiancé when to see Dr. Lauren Greco for a routine cleaning and X-rays. we were so happy how she treated us, cleanliness of the office and rooms and also the professionalism of the whole experience. I would give it 10 stars if yelp allowed. Would recommend to anyone looking for a great dentist experience.

Dr. Greco did an amazing job bonding my 2 front teeth which were discolored and had chipped. They look beautiful! She is a perfectionist and worked on them until she was completely satisfied. She also has a wonderful bedside manner and made me feel relaxed. Her office staff is also kind and very helpful. Highly recommend!

I met Dr. Lauren Greco a few years ago at a Dental Continuing Education course, and am very happy that she’s become my dentist! Dr. Greco shares my commitment to lifelong professional development and I know that I am in excellent hands. She is extremely thorough, gentle, and concerned at all times for your comfort. I highly recommend her for all of your dental needs.

The office is very nice! There was no wait time! I felt very safe (everyone had a mask and PPE) . Dr. Greco was very thorough with my exam. She explained everything. Carolina took my X-rays and it was a quick and pleasant experience. Best dentist! Great location with parking lot in back. Wonderful practice! Highly recommended!

Dr Greco and Dr Shaffer are wonderful dentists. I had a moler that cracked and needed immediate attention, not only did they accommodate me the same evening but made me feel super special and made me relax while they were performing the extract. I highly recommend them over any chain outfit. They are truly wonderful and caring.

It was a great experience. Lauren Greco and the entire staff were very thorough, open and honest which is a great comfort. They made sure I was comfortable through my entire visit. Everyone in the office was super friendly. The office came recommended to me and I would gladly pass their information on.

Every doctor in this office is amazing. We switched from a local dentist who was recommending unnecessary procedures for both my husband and I. This office is honest about what is needed and don’t try to add on anything unnecessary (like whitening or extra cleaning procedures outside of insurance). Our daughter, who has major anxiety actually loves going and our infant had a great experience too. They are available and even FaceTimed us when our younger daughter took a spill and was bleeding from her tooth after hours. They are simply amazing.

Dr. Greco is simply amazing! I have never liked going to the dentist in the past because I never had a great experience with the dentist him or herself. Dr. Greco went against the odds. She is extremely sweet, personable, and professional and has made my experience 10/10. The assistant is super sweet, as well! Highly recommend!

Melody A. (Source: Zocdoc)


Best dentist ever!!! Had some discomfort over the weekend and they were able to accommodate me the next day. Extremely kind, knowledgeable and knows how to make you feel comfortable. Office was clean, organized and , and they followed all protocols to ensure proper safety of all patients. Highly recommend this office!!!

Today was my first visit and I was beyond impressed. The entire staff was so friendly and accommodating. I don’t think I waited even 3 minutes before heading in for my cleaning which was so gentle and thorough. Dr. Greco took great care in speaking with me and addressing any and all of my questions. I will never go anywhere else.

G Y. from Plainview, NY (Source: Yelp)


I absolutely love and trust Dr. Greco and Dr. Shaffer!!! They are very professional, personable and very genuine. I live almost an hour away and will go to see them because they are trustworthy and so good. I’ve had a bad experience with a shady dentist prior and will never go back. I even had my kids change their dentist to see Dr. Greco and Dr. Shaffer. ^_^.

Hilary T. from Long Beach, NY (Source: Yelp)


First off, I absolutely love both Dr. Greco and Dr. Shaffer. They are so incredibly professional and caring. I had an issue with one of my teeth and they helped me navigate the waters. Today, I went there and had a filling done. It didn’t hurt, went very smoothly and was a good experience. They make you feel like family when you are there. They treat their patients with the utmost respect and that’s very much appreciated. These two dentists know their stuff! They may look young, but they both have knowledge and expertise that other older dentists don’t have! Both Dr. Greco and Dr. Shaffer know all the newest techniques in the dental industry. I recommended them to my son and my niece who also go there and love them. I highly recommend them to anyone who wants a competent, caring dentist!

My daughter Isabella was seen by Dr. Greco and she loved her. She is very afraid of the dentist but she made her feel very comfortable and explained everything she was doing step by step. The staff is amazing. I highly recommend Polished Dental Care.

Dr. Greco is not only a phenomenal dentist. She is a person of great integrity and character. I am attorney who rents in the same office building as her (and also a very happy patient). Most recently a client of mine lost a 15k settlement check—-making the situation worse he informed me that he informed the check. Upon hearing this news I ran back to my office in a panic. I opened the door and the check was slipped under the door, with a note from Dr. Greco indicating she found it in the parking lot. The world needs more people like Dr. Greco. Gifted in her dentistry and superb in character

I love both Dr. Greco and Dr. Shaffer. They are professional and know their stuff! If you are looking for a great dentist in the Merrick area, I highly recommend these two dentists. I’ve been going to them since they opened almost two years ago and have been very satisfied. They make me feel comfortable and they explain everything, unlike many of the other dentists out there. My son and niece also go to them and love them!

I went to Polished Dental Care on April 1st, 2017 and had a positively wonderful experience. They are conveniently located near major roadways and I had no trouble finding their location. The office is well lit and comfortably cozy like a spa. Their professional and friendly staff greeted me as soon as I entered. I was cordially invited to hang up my coat, make myself comfortable and was even offered a cup of coffee, tea or water. After settling in, I filled out the necessary paperwork on the office’s custom electronic tablet which was fast and very easy to use. My checkup and cleaning was done with Dr. Greco. She is fantastic. She was very attentive throughout the appointment and explained everything she was doing in great detail. I had several follow up questions after my cleaning and she answered all of them in a friendly and professional manner. For those that dread going to the dentist I recommend giving Polished Dental Care a try. You might actually look forward to your next check up!

Kiera H. from Amityville, NY (Source: Yelp)


I recently saw Dr. Greco at Polished Dental Care and I was beyond happy with my experience. The office was very clean and all of the equipment was new and top of the line. She was even able to use a camera and show me some areas I was missing when brushing! I was really appreciative of the amount of time she spent educating me about ways to prevent cavities and clean problem areas. I would highly recommend.

Lauren Greco is absolutely nothing short of amazing!!!! She made me feel so comfortable and at ease with my visit. I would recommend her to my family and everyone around the world. Before today i never had an experience at the dentist like i did today. I feel sensational & that is because of Lauren Greco.

Jennifer G. (Source: Zocdoc)


I absolutely LOVE Dr. Greco!!! She is so personable, and the most gentle dentist I’ve ever had. I had jaw surgery, and many horrible dental experiences for years until I met her. She corrected all of my dental work, and I felt no pain at all. She takes her time to explain everything in detail, and always puts her patients best interests above all. I absolutely trust her, and her recommendations. I cannot say enough good things about Dr. Greco, and staff! Everyone is so welcoming, and I no longer dread going to the dentist- it’s always a great experience. I HIGHLY recommend Dr. Greco to everyone I know, and would never go to anyone else.

From the very first time I went in, to the follow ups I needed, Dr. Greco and everyone else working here made me feel at ease every step of the way. Her demeanor was always very kind, professional, personable, and just very easy to get along with. Not to mention her actual dental work and skill were both just something I cannot fault in any conceivable way. I was frequently checked in with throughout the sessions making sure I was OK and not in pain (which I never was here). It’s very apparent they know what they are doing and actually care about their patients. Dr. Greco was always very clear about what was going to happen, what I should expect, and how everything will proceed going forward. She was also easy to schedule with and was willing to work with me to find availability that fit us both.

I recently went to Dr. Greco for a chipped tooth and the experience was great. The facility is clean and well maintained and the staff (including Dr. Greco) were incredibly nice. She did a great job on the filling procedure and was able to spot another cavity from an old filling that fell out and fixed that one as well. The whole experience was pleasant and painless and will easily recommend Dr. Greco to friends and family.

Katherine S. (Source: Zocdoc)


My sister recommended I visit Dr Greco because she had nothing but nice things to say about her and when I met her she made me feel welcome and comfortable and she remembered things from past conversations with my sister that were relevant to my experience. She was very thorough and gentle and I am looking forward to my next cleaning with her !

Dr. Lauren Greco’s office was a pleasure to visit, they have prepared for a Covid safe appointment for you. Checking in is touch less as you access everything you need via your cell phone. Everyone in the office wore masks, including yourself until you sit in the dental chair for your procedure.. Dr. Lauren has a wonderful bedside manner and is very personable to my you feel like you’re dealing with an old friend. Her staff are all friendly and professional. I will surely recommend Dr. Lauren to all my friends looking for a new dentist.

I can not recommend polished dental care enough! Dr. Lauren Greco is an amazing dentist. I called for an emergency root canal and dr. Greco took me right in no questions asked! May I add this was not my dentist office I was calling around looking for an appt and could not get in anywhere. Seeing how quickly she got me in showed that she must be a caring person and that she was! She was incredible! Thankyou Dr. Greco for all your help! You’ve gained a new patient and I will highly recommend you to everyone I know.

Fantastic, they take care of my children and I – I love it. Staff is so kind and welcoming. My children love to see their Dr. Lauren and Jen. Dr Schaffer took us in right away when my daughter needed an emergency extraction. Dr. Greco came from home one day to see my daughter on her day off! Talk of dedication! I couldn’t ask for more, this is what healthcare needs. Best team around! Won’t go anywhere else.

Honestly, Dr. Greco is the best dentist that I have ever been to in my life and I’m so glad that we moved to her practice. Having her as our family dentist is truly a breathe of fresh air. She’s amazing with our kids (ages 6 & 3) and they actually like going to see the dentist. I’m so lucky that I happen to find her on zocdoc. She is absolutely patient with the kids and interacts with them so well. I will always recommend her to anyone looking for a GREAT family dentist. We enjoy our visits so much that we look forward to booking our cleanings ahead of time. Thank you so much for such great personalized services and experiences.
