Dr Alan Block is the best. I never loved my smile until I came here. He takes his time with you and really works with you to make sure you are comfortable threw the whole process.. From scheduling appointments to appointment punctuality this office makes the process so smooth. They really are "patient friendly" from beginning to end.. I cant believe I am saying this, but I love going to my dentist.

Consistently kind and thoughtful, careful dental care. I highly recommend this dental practice as all of the staff/team are professional and patient throughout the entire visit, every time - cleanings to procedures, they're excellent.

My 1st time at this location and the staff were very kind and welcoming. The dentist was also friendly and was able to treat my chip tooth without any issues. I definitely recommend coming to this location.

I’ve been seeing Dr Block for 18 years. My husband recommended him while we were dating, and the dentist I was seeing made me uncomfortable. My husband has been with him longer than he can remember. We have since moved to Long Island (12yrs ago), and I refused to give him up. My now 13 year old has required several teeth to be pulled, and I won’t bring her anywhere else because she’s only known Dr Block, and trusts him. He is very welcoming and friendly. He puts you at ease, and is very sensitive to any fears you may have.

Highly professional. Knowledgeable. Skilled. And as the name says, friendly. This applies to the entire staff. My procedure, upon this first visit, wasn't complex, but often times we can quickly tell how capable someone is. I've had premier dentists over the years, including the same two who worked with First Lady Jackie Kennedy, as well as the dental school director at UCLA. Dr. Koffman was a find. One last thought. The practice is more up to date than their website. Don't let that dissuade you from their practice.

TI called them and they didn't take my insurance. So I moved on to a different a different dentist. But they called me back and went above and beyond to make it work. Dr Lina Koffman. Shes a sweet Bulgarian redhead who did a AMAZING job fixing my chipped tooth after a car crash.

I’ve been coming here for two years and it’s by far the best dentist experience I’ve ever had. The receptionists are professional and so accommodating to scheduling needs and the care given during cleanings and checkups is amazing. The dentist is thorough and truly gifted. He’s knowledgeable, an expert in his craft, and really patient with me. If I could give this place 10 stars, I would. Offices are clean and up to date. I’m so happy I found this gem.

I went in terrified as soon as I walked in I was greeted by the office manager and the receptionist who were both very nice, when I was called in the back the dental assistant that took my X rays was super nice she reassured me that all we be okay she helped me relax when DR Koffman came in she greeted me my whole entire exam she explained everything in full detail she made my visit the best dental visit I have ever had ! This will be my dentist office moving forward highly recommend this facility

Dr. Lina is incredible! She is patient, takes her time to have you understand the work she will be doing, and most importantly - always makes sure you are comfortable and not in any pain. It has taken me some time to find a dentist that I love and I am so thankful I stumbled upon Patient Friendly. The staff is really sweet as well! I recommend this place to everyone - esp. Dr. Lina!

Implant itself and bone graft was put by Dr. Iyman who was very professional and he did a great job. Only time when I felt pain was during injection of anesthesia. After that no pain at all even he was drilling whole in my jawbone for the implant.
Also Dr. Iyman explained everything including any possible complication, how to further take care of it, showed me how the implant and the extra bone looks like and even made pictures of it in my mouth to show me. However, I always have a lot of questions so it could be a bit aggravating.

Dr. Block was also also very professional and kind. I feel like both of them: Dr. Iyman and Dr. Block care about their patients. He made impressions and very good looking temp crown. Previously I had a bridge which looked kind of pathetic, because one fake tooth was very wide and other very narrow, which made my smile look kind of weird. Now I feel like my smile looks natural. Thank you Dr. Block!

Assistants and office manager were also very friendly and professional.
What’s even better, the day after surgery I received a phone call from them just to check how I am feeling. Unbelievable, no other dentist did call me just to see how I am doing after minor surgery.

I have been seeing Dr. Allen Block for about 10 years and he is really nice, patient and caring since he knows how much I dislike coming to the dentist.

As much as I hate coming to the dentist Dr. Allen makes it easier.

As a newcomer to the area and lacking dental insurance I had no idea where to begin.
I found Dr. Block through YELP reviews and am so grateful.

All of the staff is knowledgeable, competent, kind, accommodating and helpful. Each goes above and beyond to make you feel comfortable and at ease.

I highly recommend coming here for all your dental needs!

I’ve been a patient of Dr. Dennis Block for about 6 years now and he is by far the BEST dentist I have EVER had!! Dr. Block is extremely considerate, honest, and will never recommend any treatment that you don’t need. I HIGHLY recommend him. His top priority is always the patient’s comfort.

Yelp Review

Kevin D

As a new patient with an emergency, Dr. Block’s office squeezed me in on a Saturday afternoon. He and his staff are friendly and professional, and the facilities are clean and up to date. He listens to his patients’ concerns and addresses them appropriately.

I had a tooth extraction performed there recently which went as smooth as could be expected with minimal discomfort. Having had a relatively major dental procedure performed already and seeing how professionally it was handled, I have no reservations in giving Dr. Block and his staff five stars.

Jennifer Perez

I absolutely LOVE Dr. Block’s office. The minute I walk in, it feels like I’m visiting my family. The staff is so friendly and comforting! I had my ZOOM done here, and my teeth are sparkley white! Dr. Block is so attentive, compassionate and understanding. He answers all my questions and always gives me THE BEST options for any treatment I need. The office is great at working with my financial situation and insurance company; the list is endless. I can’t imagine seeing another dentist. This is the office to go to, for SURE.

As much as I dislike going to see the dentist I have to say that Dr. Dennis S. Block made my experience better than any other dentists I have seen in the past. He is knowledgeable, kind, and made me feel as comfortable as possible. He was very professional and explained in detail what procedures I was going to get.

Also, the staff is very professional and friendly, Sandy the office manager was great with the follow-up phone calls and answering the questions that I had.

Dr. Block referred me to Dr. Iyman who is a periodontist. I had a great experience with him and he performed periodontal surgery. The surgeries went well and without any complications.

I highly recommend coming to see Dr. Dennis S. Block for dental services!

Yelp Review


I just got three cavities filled by Dr. Block. And I was astounded by how good the service was and how patient the entire staff at the office was. They have a new procedure for numbing my teeth that was amazingly simple and my jaw doesn’t feel like I just got punched in the face. Good vibes and good service!

Friedhelm M

there is no more caring dental facility than Dr. Blocks practice. Your treated with dignity, respect, and you recieve the best care. my family and friends have been coming for at least 20 years now. they instruct you on how to improve your health as well as to fix any problems you may have. I would highly recomend their services to any looking for excellent dental care. I have recomened them to all my family, and they now all see Dr. Block.

H. S.

My husband and I have been patients at this practice for over 4 years now. We found them through our insurance company search engine (so glad we tried them out). Our dentist is Dr. Alan Block (brother of Dr. Dennis Block). He is wonderful. Always very accommodating and comforting with great sense of humor. Even when I kept having troubles with my crown I had as many appointments as necessary without any extra charge. The office staff is very great and nice (big thing for NYC when so many people are harsh and rude). I was also very pleased to notice that they do whatever they can not to incur extra cost on me.

BOTTOM LINE: I had a great experience – and I highly recommend this practice.

I have been going to Dr. Block for about 36 years. I trust him so much. I remember a few years ago I was working for another dentist in another state and I drove to New York because I had a tooth ache. I have never had a problem.

Great experience


Charlie H.

I can’t say enough about how wonderful my visits to this office are. They treat me like royalty. I needed a lot of fillings and a couple of Root Canals and I was very nervous coming in. But the staff and Dr.Block were extremely patient and gentle. I have never experienced pain at this place. They have this shot where they numb you but you don’t feel the injection. That thing is great! I had a Zoom whitening after they finished my dental work and my teeth are sparkling. Everybody at work keeps commenting.

I would recommend this place to everyone. Dr.Block is a fantastic dentist and they took my insurance in full. I have Metlife. I didn’t have any copays or anything like that. So i’ll be coming back for my regular check ups. Make sure you see Dr.Block, and tell him Charlie sent you!

Paul A.

My visit at the office was excellent. The staff was very friendly and professional. Dr. Block is the best dentist I’ve ever had. They’re very convenient and always cater to my needs. I highly recommend this office for all your dental needs!

I have had quite a bit of dental work done by Dr. Dennis Block throughout 2012 and through the beginning part of this year and I have been very happy with the results. He works with people who don’t have insurance and so his prices are very reasonable compared to others. I have nothing but praise for Dr. Block and the entire staff for maintaining a very professional and comfortable atmosphere and I highly recommend them for anyone’s dental needs.


Denise M.

My experience at Dr. Blocks office has been amazing. I was recommended by a co-worker who insisted I would not be disappointed. I must say from the moment I walked into the office the staff was so friendly and attentive. I was treated by Dr. Koffman. Her patience and delicate approach has eased my fear of going to the dentist. She makes sure you are well informed and makes the experience painless


Mario M.

My experience at this fine establishment was absolutely outstanding. The staff could not be more friendly even if they tried. Not only do they make me feel comfortable, but they make every situation go by with ease. I highly recommend Dr. Blocks office.


Michelle U.

I haven’t been to the dentist in 3 years and this experience was wonderful. The staff is very helpful and kind. Dr.Block was very patient and informative. He told me everything he was doing before he did them. I really do like that it’s state of the art with the digital X-rays. I’ve never had that before. And the office is beautiful. I absolutely recommend this place and I will change my children’s pediatric dentist to here


Jackie C.

Just a few words to thank you and your amazing team for their professionalism, dedication, care and enthusiasm during my dental treatments and surgeries. Dr. Block and his OUTSTANDING team have given me a new level of confidence in my smile and I must now show my teeth to everyone!.

The dentists at Dr. Block’s office are all extremely good at what they do. I am a patient with very sensitive teeth and gums and they are very careful and accommodative of your needs and your comfort level. The office is clean, the staff members are friendly, and you feel at ease. I won’t go anywhere else.

His staff is an excellent addition to an already polished environment. I always know I am in good hands and in the end I feel healthy. I highly recommend anyone looking for a Dentist…Dennis S Bock should be your first choice.


Pasquale C.

Dr. Dennis Block is a wonderful dentist! I was dentist averse for many years due to bad childhood experiences and as a result I had developed several cavities, I got a recommendation to see Dr. Dennis Block from my mom and I have never looked back since. Dr Block worked with me to resolve all my issues. I now maintain a regular schedule of maintenance, and I have also gotten some cosmetic work done as well. My teeth look and feel great and I have a happy, healthy mouth. Kudos to Dr Block and his awesome team for running a great practice. I would also like to add that they were able to work with me on a schedule that fits me well. Give them a call to get your next check up

1 (718) 304-0595. Ask to speak to Sandy, very polite and professional.

Lets them know Pasquale referred you. Thanks.


Elizabeth J.

I have been a patient of Dr. Block for several years now. The staff is very friendly at anytime of the day and the Dr. is a very gentle and caring dentist. He listens if you complain of sensitivity and remembers for your next visit. He adjusts his tools which is great. They have a very nice and clean office. I would definitely recommend.


Lisa H.

Dr. Block’s office is a modern dental office with very welcoming and professional staff. The office is on the second floor but has a stairlift for those who need it. Office wait time is normal and was not too long. When Dr. Block did my cleaning it was very thorough, which I liked. Overall, very good place to come.



I have always had a fear of going to the dentist for as long as I can remember. When I walked into Dr. Block’s office I hadn’t been to the dentist in 5+ years (I know, I’m bad.)

But as soon as I walked in I was welcomed by very friendly receptionists and I immediately felt comfortable. I was seen fairly quickly (about 5 minutes before my scheduled appointment). I was introduced to Dr. Block and Lana (the dental hygienist). They were warm and welcoming and I was beginning to feel more at ease. But, I was still a bit nervous. Dr. Block checked me and he told me that I had a lot of work to be done and he explained what we had to do, and he didn’t make me feel bad about my dental issues (which was a big plus, because I was most afraid of that.) I had a fairly painless deep cleaning and Dr. Block was gentle and encouraging. Lana gave me some tips about dental hygiene and I felt so much better about my situation. I was due back for follow up in about two weeks after and I was ACTUALLY LOOKING FORWARD TO GOING TO THE DENTIST! I have never felt like that. Dr. Block and his staff are friendly, knowledgeable, and just plain AMAZING. I feel 100% better about the health of my teeth and gums and I owe it all to them! I am so happy that I found such an amazing dentist and I will definitely be going back for a very long time.
