Check out what some of our happy patients are saying about us:

Dr. Steve has been my dentist since I was 17 years old and I can without a doubt that he is the best dentist around. I have a a filling on one of my front teeth that chips every couple of months, as you can imagine this is a large inconvenience since it is a front tooth. Dr. Steve always manages to fix my tooth and make it look better than it did prior to the chip. My tooth one time chipped while Dr. Mantinaos was out of town, I tried another local dentist in the area and left the office in tears at how terrible my tooth looked and felt. NEVER AGAIN. Dr. Mantinaos is the ONLY dentist for me and I recommend him to EVERYONE.

I consider this dentist the Men In Black of dentists. I say this because they have the best of the best of the best. The staff are the all time best AND the nicest staff EVER of all dentists I’ve been to and they absolutely care for their patients and they make me feel like family. I absolutely LOVE this dentist and his staff. Kudos to all and PLEASE keep up the amazing work.

This is one of the most innovative practices with a dentist who has extraordinary skill, expertise, and a awesome personality to match. I loyally come to Dr. Matinaos with my children for 6 years despite the many other dentists that are closer in proximity. The office is modern equipped with entertainment and music. It is a perfect combination for both adults and children. Whether you need a general check up or more in depth procedure, this is the best place to come.

Teri M. from East Elmhurst, NY (Source: Yelp)


I have been dealing with an ill fitting crown and TMJ for several years. I have been to quite a few dentists, and thankfully I finally found Dr Mantinaos! Not only is he an excellent doctor; he is above all a great and empathetic person. I am so happy with the work he has done, and he is now my favorite dentist. He has helped me get relief for my TMJ, outlining and speaking with me regarding a treatment plan, and what his goals for us would be. My bite is better and my mouth has finally got the relief it needs! I highly recommend him.

Dr Steve is my favorite dentist by far. He is very caring about his patients comfort and every step of the process is discussed. I am not a fan of visiting the dentist at all but the pleasant staff at Into White Dental makes it a breeze and always a pain free experience. I would recommend Dr Steve to all looking for a new Dentist. Keep up the good work!

Nicolas D. from Long Island City, NY (Source: Yelp)


Great dentist.  The staff and Dr. Mantinaos at Into White will not give you attitude, and will provide effective and high-quality dentistry. I also appreciate that Dr. Mantinaos explains everything he does to your teeth all the time, and you really know everything that is happening all the time, what needs to be done, why and how.  Obviously going to the dentist isn’t anyone’s favorite activity, but there you will get excellent service to maintain healthy teeth. Highly recommended, whether you need a checkup or you are having some problem with your teeth.

Shannon T. from West Babylon, NY (Source: Yelp)


I travel almost an hour to go to this office. It is so worth the time and traffic. The staff is great. They are upbeat and personable. The office is really nice. Modern with touches of original architectural elements. As far as Dr. Mantinaos…I adore him..straight foward, attentive, and extremely talented. Appointments might take a bit but that’s because he’s so thorough. The outcome is well worth it. Parking is a bit of a pain, but if you circle enough you will find a spot.

Susan Jung (Source: Google)


Dr. Mantinaos is extremely professional and attentive. Very talented and skillful dentist. Really glad I found this office. As long as I live in New York I will continue to come here for any and all dental work. His front office is also very helpful and knowledgeable. Clear estimates are given when asked and the office runs very much on schedule.

I’ve been going to Dr. Steve since he opened his practice on Vernon. He has helped me with cleanings, fillings, root canals, implants, crown work. I’ve done it all and have never had any issues. He is professional but has a gentle touch. His equipment is top of the line and the office is immaculate. My whole family now goes to see Dr. Steve. In fact, my kids love going to the dentist! (which is incredible because I hated it when I was a kid) He puts them at ease and of course they love that they can see the inside of their mouth on the TV screen or watch a show while getting their teeth checked. Take it from someone who’s had a lot of experience with dentists all my life – he’s awesome and so is his staff.

Steve B. from Long Island City, Queens, NY (Source: Yelp)


My local dentist, Steven knows his stuff! Based on Yelp reviews my GF came here, then she recommended I come for a checkup as it had been too long since last visit. It’s a smallish storefront place, with one dentist and a few assistants who do cleanings etc. they’re open 930-6 I believe and will do first-time visits on Wednesdays & Saturdays only. So why do I like this dentist? You can tell he knows his stuff, is willing to discuss treatment options and doesn’t push for the most expensive option. They know how to work with insurance rules to find the best treatment within your plan. And they do what they can to make you feel comfy – playing requested Pandora stations at a solid volume while you get work done on you. And beyond his strange liking of Ellen’s show, I’ve been happy (as happy as you can be at the dentist) with my visits here. I’d much rather go to any other 5, 4, or 3-star venue on my list, but if I have to get my teeth cleaned I’m happy to come here.

L. G. from New York, NY (Source: Yelp)


Love Dr. Steve and his upbeat wonderful staff!!! He offers an incentivized dental program that keeps you healthy and offers generous discounts for thorough services. Just had a cleaning with The wonderfully sweet Michael one of his dental hygienists. Overall the best dental visit I’ve ever had! Thank you Dr. Steve and Into White Dental Arts for being so caring and compassionate!

My family and I have been going to Dr Mantinaos since he opened. My husband and I are very happy with “Dr Steve”, still impressed, each time, by his professionalism and attention to details. We moved both our kids here from their kiddie dentists in Manhattan and our kids love going to “Dr Steve”. He is one of the most genuinely caring professionals we have ever had the pleasure to work with. And the dental work he’s done on us are perfect each time, we never had to follow up – and trust me, we’ve done it all – crowns, implants, many fillings, cleanings, root canals, all of it!!

Lawrence R. from Detroit, MI (Source: Yelp)


Visited again today, first visit in a year or so. It doesnt get better than this place. Beautifully decorated and equipped offices – very human scale – everything fresh and squeaky clean. Dr. Steve is just the best – with him, it’s all about you and your comfort and taking care of you the right way. Going to the neighborhood is fun too, just two short blocks from Vernon Ave # 7 stop – cute neighborhood – interesting looking restaurants, coffee shop, etc. – probably a good place to go for brunch on a weekend. Again, nothing not to like about the neighborhood, or the Dentist. Just the very best there is.

I needed a new dentist after moving to Long Island City. Into White was covered by my insurance and just around the corner so I decided to give him a try. I have gone to Dr. Steve Mantinaos three times so far, twice for cleaning and once for replacement of a filling. Every time has been excellent. In fact, this was the third time that the filling was replaced and Dr. Mantinaos said that if done right by the other dentists I shouldn’t need to have it replaced. His repair was the most thorough and best looking of all the prior repairs. I don’t think this one will need to be replaced for a long time if at all. In addition, the office is clean, comfortable, well maintained, professionally staffed. I highly recommend Into White and Dr. Mantinaos.

A. N. from Long Island City, NY (Source: Yelp)


Dr. Mantinaos is wonderful. He is warm, kind, patient and caring. He went out of his way to make my extractions as painless an experience as possible. He is knowledgeable and answers any and all questions. My extractions took at least an hour longer than we anticipated, and he took his time regardless. He never rushed and was more concerned about my comfort than his schedule. His office is new, and he uses all brand new state of the art equipment. He is a highly skilled dentist, and he has the best personality. I cannot recommend him enough.

Monica Matocha (Source: Google)


BEST DENTIST EVER. Look you guys, I am a freak about the dentist. If I experience any kind of tooth pain or ANYTHING, I have to know what is happening. They always fit me in even if it’s last minute. The cleaning is always top notch, and Dr. Mantinaos is super awesome, kind, and knowledgable. I’m the type that will literally ask every single question and need every detail and he doesn’t mind answering. 🙂 He makes going to the dentist fun! I can’t even believe I just typed that, but it’s true. I always leave there so happy and thankful I have such an amazing dentist!!!!! I can’t say enough good things. So if you are searching for a dentist, LOOK NO FURTHER!!!!

Johanna G. from Manhattan, NY (Source: Yelp)


I can not say enough about Dr. Mantinaos, his phenomenal staff and his state of the art office. He is a very skilled dentist with a gentle hand and a warm demeanor. I unfortunately had to have an extraction recently and he made it the best experience possible…no pain during the procedure and none after.  He truly cares about his patients and I consider myself beyond lucky to have a dentist like him.

I just left the office and could not wait a minute longer to tell of the wonderful experience I just had at this facility. Staring with the staff, the look of the place, and meeting the best dentist in the world has changed my life. I procrastinated for such a long time on fixing my teeth and was ashamed of what my teeth looked like. It took a bad experience with another dentist to bring me to Dr. Steve. My wife is a patient of his for awhile and raved about him! As soon as I met him there was a calming demeanor about him. I trusted him. He had a plan for me and I was so relieved. Sometimes it takes a bad experience to bring you to the right place. Dr. Steve is the right dentist and Into White is the right place. I highly recommend them!!

Dr. Steve is an exceptional dentist who pays attention to detail. He takes the time to setup a game plan with you (the patient) before the work starts and explains every procedure he’s doing. He does great work and puts you at ease. Dr. Steve has a good spirit and bedside manner but balances it with the right level of professionalism/seriousness. All the office staff are polite, professional and friendly. No complaints!

Best dentist experience ever! BY FAR. Just moved to lic and was dreading finding a new dentist cause I’m pretty much phobic about all things dental. Everything about this place was top notch… On time.. fast… Nice staff… So professional and Dr. M is super nice and cool and I can seriously tell her cares! And knows what he’s doing!!!! He made sure I was completely comfortable! I’m so happy to have found such a great new dentist. Seriously not even dreading having to go back in 6 months!!!

Thomas Tatarian (Source: Google)


I’ve been a patient here for years now and it is the best experience I’ve ever had when it comes to dental care. From routine cleanings and exams, to more serious work, the experience exceeds expectations. Dr. Mantinaos and his staff are kind, caring, and good humored, making every visit a pleasure.

Donald Cannon (Source: Google)


Dr. Steve is an excellent dentist; I recommend him without any hesitation. I got 4 implants and several crowns and it was the best decision I ever made. The whole experience was painless and the quality of care was as good as it gets. If you’ve got longstanding dental problems, get them fixed. You’ll never regret it.

K. Agoritsas (Source: Google)


Great dentist with excellent skills. Always makes my wife and I feel confident when he is performing dental work with those little tools. We were referred to him by a friend and have stayed with him for years now.And by the way, we drive from Douglaston,Queens to his office and it is worth it. The dentist we tried around here was only interested in making money quickly. Dr Steve makes sure he doesn’t rush any dental work and it has worked out great.

Enrique S. from White Plains, NY (Source: Yelp)


Coming from a someone who really hates going to the dentist and has visisted numerous dentists in my lifetime, I have to say Dr. Steve is amazing. He’s very chill, laid back guy and is very gentle with your teeth. You can tell that he really knows his stuff. The rest of the staff is really nice as well and will work with you and your insurance company to get the whole billing stuff all figured out. They will also call you the day before each appointment to remind you of your appointment. As far as the decor and the equipment goes, it’s all very clean and modern. The waiting area is very cozy and they have a tv going to keep you distracted while you wait. The equipment in the patient rooms are very clean and modern. You can tell that they invest in the latest technnology which really comforts me. The doctor will even ask you if you prefer to watch tv or listen to music while he’s working on you! So far i’ve been very happy with all of the dental work that i’ve received from here. The doc wants to be known for performing quality work so he makes sure that his work is done right and that it lasts. All in all, going to the dentist is not one of my favorite things to do but since I must then i’m glad that this place exists.

Nicole B. from Scottsdale, AZ (Source: Yelp)


I had a great appointment this afternoon when I had my teeth cleaned. The dental hygienist was knowledgable and professional. She explained how to floss properly and was very nice. The doctor/senior dentist was very down-to-earth and listened to all of my concerns. He checked the teeth I was nervous about and made sure to investigate what was going on. He explained things in easy to understand terms. On a side note, I am normally scared to go to the dentist, but the lobby felt nice and welcoming–comfortable! Per usual, free toothbrush and free floss/toothpaste.

Jason R. from Long Island City, NY (Source: Yelp)


I’ve been going to Dr. Steve for almost 10 years and I can say without a doubt that he’s the best dentist I’ve ever been to. Before I went to Into White Dental I had severally yellowed front teeth from a bike accident I suffered as a child. Until Dr. Steve, no dentist knew how to get my teeth back to their natural color, but because of his expertise, and an advanced procedure, my teeth are back to their natural color and in better condition then ever. Dr. Steve is as honest and caring as they come, he runs a neighborhood dentistry service, not a corporate office trying to up-sell things you don’t need. His office is clean, his staff is knowledgeable and kind, and one of my favorite things of all, my appointments always started on time. I’ve recommended several people to Into White, all of them were glad I did.

Jen G. from Brooklyn, NY (Source: Yelp)


This review is long overdue, but Dr. Steve deserves every star he gets and then some. First, if you aren’t into the dentist, this is the place for you. The staff is very attentive and kind and the office is kept immaculate and up to date with equipment. You can watch TV in the chair while you get your dental treatment. Second, (but not least) Dr. Steve knows his stuff. He’s not pushy, he’s not overbearing, he won’t try to up sell you a bunch of treatment plans. He tells it like it is and does what it takes to give you the results you want. In fact, he earned my business by telling me to try to save my teeth while countless other dentists told me to take the more expensive implant route. He’s not the cheapest dentist in the book (if you have decent insurance or can get some, do so before booking an appointment), however you will get quality work and great advice on your overall tooth health. For me, it took some time but I followed his detailed advice and I’m glad I did. Dr. Steve even encouraged me to go to specialized dentists while also seeing him for lingual brace treatment twice a month. Today, (five months in braces) not only are my teeth doing much better, I have a great new smile of my own teeth. I know I read like a commercial but I tried it and I know it for myself. 🙂 Into White Dental Arts gets a highly recommended from me.

It took me several years to find the right fit to care for the needs of my teeth. I was recommended by a friend which until this day I am glad I moved upon this recommendation. Dr.Steven Mantinaos work is exceptional. He has been open for about 9+years and has not lacked in the work he provides to his patients. I say that because from the start of my treatment (which has not been completed yet) but the work and change has been amazing thus far. I have also heard great things about this dental office. If you are looking for lasting care for your dental hygiene I reccomend this location 110%! Before I end my review I also must commend the amazing staff. Team work and professionalism are what matters and they all work together to take care of the needs of each patient individually. Go visit their website, call the office to schedule your 1st visit and right after write a review. I am sure you won’t regret it!

I went to see Dr. Mantinaos for a 2nd opinion, and I left feeling better, informed. He listened well, answered all questions i had, and examined me fully. His office ( bathroom included;) is clean and pleasance. The ladies at front desk were welcoming. THANK you good doctor!!

Enrique Jr. C. from Knickerbocker, NY (Source: Yelp)


Dr. Steve Mantinaos is a brilliant dentist with a warm & calm demeanor. I’ve been Dr. Mantinaos patient for 9 years. I met Dr. Mantinaos in 2007 when he worked at a practice in Manhattan and I followed him to another practice in midtown Manhattan. Because I knew that I was in the best care with Dr. Mantinaos. When I received the news that Dr. Mantinaos was to open his own practice at Long Island City, NY. I was not going to commute to Long Island City from the Lower East Side. The commute is out of my way. But I knew that I would not find a great doctor like Dr. Mantinaos. So I decided that I had to give a try and travel to Long Island City in knowing Dr. Mantinaso and the excellent service that I have received from previously procedures. You see I’ve had many dental procedures, from tooth implants and two tooth extractions, bone grafting and all the procedure have been with little pain. Thanks to the skill hands of the doctor. The dental technicians to the staff at the front desk are very helpful & personal. My husband is also a patient of Dr. Mantinaos. I promise, you will receive the best service of the best with Dr. Steve Mantinaos. A faithful patient. Elsie Calo

I had procrastinated seeing a dentist for many problems I knew I had because of previous unpleasant experiences with dentists. Finally, I had to give in and someone from work recommended me to see Dr. Mantinaos. I would give him 10 stars if I had the option to. He is kind, gentle, and the best dentist I have ever had. His equipment is high tech and immaculate. I’m not surprised that everyone on yelp has given him a 5 star so far. You should go, you won’t regret it!! He is also reasonably priced.

If anyone would tell me that extraction of a tooth can be painless I would never believe it – unless you come to the office of Dr. Mantinaos. When I come in for an emergency extraction I was expecting very painful visit. Instead Dr. Mantinaos was very gentle and very efficient. His warm personality help me calm my nerves. His swift numbing process was painless and in few minutes the scary procedure was done. I still cannot believe that I did not feel any pain! I must add that it was difficult extraction and he made it look like a simple one. I can’t stop talking to all of my friends and bragging about painless dentist visit! Also Dr. Mantinaos staff is very polite, warm and kind. I felt welcome when I come in for a visit.

I’m a recent transplant to the city and had to find a new practice after having a nightmare tooth situation (literally a piece of my tooth fell OUT) and saw Into White Dental Arts PLLC online, called them – not only was the reception kind and courteous, they worked to get me the quickest appointment possible. After fixing the initial problem I ended up having to have a few other things fixed. Each subsequent appointment was painless, efficient and and an overall wonderful experience. Dr.Steve and his team are the first dentist I have ever LIKED going to! It’s like being taken care of by family, everyone is warm and receptive. I would recommend to anyone!

Dina H. from San Francisco, CA (Source: Yelp)


I’ve been seeing Dr. Mantinaos for several years and have always had a positive experience.  The front desk staff is kind and personable, the office is clean and well-maintained with a super comfy red leather couch, you get to pick your own music to listen to during your time in the chair, and Dr. Mantinaos is personable, knowledgable and really gentle with that scraper!  I never dread going to the dentist, and know I’m getting good care.


Having come from a professional art background, Dr. Mantinaos is unique in the world of dentistry. He earned a Bachelor of Fine Arts Degree and pursued a career in drawing and painting. Through art, Dr. Mantinaos developed a deep appreciation for science and nature and, hence, was immediately attracted to dentistry. Dr. Mantinaos earned a Doctorate of Dental Surgery from New York University College of Dentistry in 2000, graduating Magna Cum Laude. After completing a General Practice Residency the following year, the Department of Veteran Affairs Medical Center in Manhattan selected Dr. Mantinaos for a 3-year post-doctoral program in specialty of Prosthodontics. The intensive program afforded him the opportunity to gain knowledge and proficiency in advanced techniques with a wide variety of dental implant systems. In July 2004 Dr. Mantinaos was awarded a Certificate in Prosthodontics. As a prosthodontist, Dr. Mantinaos draws from a variety of materials and techniques to render beautiful smiles. In February 2018 Dr. Mantinaos was a delegate at the first TEDx MIS event during the MIS International Implant Symposium. TED is a Silicon Valley organization known for hosting innovative online talks in the scientific community. A wide variety of out of the box topics were discussed; from digital design and augmented reality in the near future of dentistry to patient centered outcome measures and appropriateness of treatment modalities.
