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

Theresa M. from Queens, Queens, NY (Source: Yelp)


I’ve been going to Dr. Dennis for at least 15 years.  Because of dental abuse by a union dentist when I was an adolescent my teeth were constantly drilled so that by the time I was an adult they were in various forms of deterioration.  I needed lots of restorative work, lots of care and someone that didn’t make me feel bad about my teeth.  I had moved into the neighborhood and decided to try Dr. Block and I was happy I did.  It was the first time I felt positive about a dentist.  I’m still going to Dr. Block and will continue to do so.

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


I’ve been seeing Dr. Block for about 6 years now and I refuse to go anywhere else. The staff is great at making me feel comfortable and Dr. Block is as real as it gets. He always tell me exactly what I need and is great at pricing everything out for me if I have no insurance, which is crucial when I’m in between jobs. The assistants make me laugh and it really helps me to relax before getting my work done. This will always be my go to dentist!

Janice S. from RIDGEWOOD, NY (Source: Yelp)


Dr. Block(s) are fantastic at what they do–painless, polite and very caring. Phone calls home to check on you! Old time dentistry with technology on the cutting edge! I have been a patient for well over thirty years, as well as my family! We would not think of going anywhere else. I just had an implant and was terrified. The procedure was phenomenal and recovery was a snap. From the friendly concerned voice of Sandy on phone calls, to the wonderful and expert assisting of Ilona to the magic fingers of Dr. Iyman and of course, Dr. Dennis Block’s expertise over all – I knew I was in the best hands possible! I am looking forward to many more years of their service so they better not go anywhere!!

The best Dentist and office I have used in my entire life. The staff is friendly, attentive and extremely professional. The Dentists are outstanding. They are as painless as a Dentist can be. I have never had a bad experience in the 12 years I have been coming here. The office is spotless.You can not ask for or get a better Dentist. I highly recommend this Dentist and his staff.

Raphael O. from Queens, Queens, NY (Source: Yelp)


Dr. Block and his staff was amazing. I felt very comfortable from the beginning. I didn’t feel any pain during a procedure and was informed of each step beforehand which was comforting as well. Straightforward for billing as well and willing to work with you. I’m very happy that I found my new dentist close to home. The reviews were right!

Christine O. from Queens, NY (Source: Yelp)


I’ve been searching for a good dentist for years and I’m happy to say I found one. Dentist visits were always scary for me but I can honestly say Dr. Block changed how I feel about them. He’s super friendly and takes his time to make sure you’re comfortable. His staff is amazing and the office is conveniently so close to home. I’ve recommended a few people to this office and all of them have nothing but great things to say.

I’ve been coming here for about 6 years. Prior to finding this place, I’d jumped around from dentist for years and have mostly had bad or mediocre experiences. Doctor Block was not only a great dentist but very kind. Now that he has retired, I see Doctor Koffman and I love her! She’s very knowledgeable, quick and super kind. As an added bonus, the entire staff is so welcoming and nice. Office is clean and I never have to wait more than 10 minutes, if that. I really have nothing negative to say about this place.

My fiancé and I are new to the neighborhood and we’re due for a dentist checkup, I googled places nearby with the best ratings and this place popped up. Hands down one of the best dentist offices we’ve ever been to. Nice and friendly staff, knowledgeable and kind dentist, and the site was well kept and clean. We will be returning for our 6 month check up and not because it’s local, but because they took care of us. What more could you ask for when visiting the dentist?

Brandon S. from Queens, NY (Source: Yelp)


Fantastic practice all round. Highly recommend. I’ve now been to Patient Friendly Dental twice, and both experiences were top notch. I came to Alan Block after having a bad experience with another dentist, and they really took care of me. Getting me in on a weekend (with a day’s notice), and working with me to get all the work I needed; done well, and done speedy. Not to mention, it’s been the most pain free work I’ve had. So if you’re a wuss like me, you’ll be in good hands here. The staff is incredibly friendly and professional. Special thanks to Sandy to being so flexible with appointments. I’ll definitely be coming back as a regular patient. Thank you! Brandon

Nicholas L. from Bushwick, NY (Source: Yelp)


It’s strange to write anything happy after a root canal, but I have to say, I’m thrilled. I called at 10am with the emergency and they fit me in almost immediately. The whole process was – literally – painless, and they’re really friendly and professional. They have a new long-term client and I’m happy to have found people I trust.

Eva K. from New York, NY (Source: Yelp)


A neighborhood gem, Dr. Block and his staff… I’ve been over Manhattan and Forest HIlls, and never found a better and nicer place than our neighborhood friendly dentist. The appointments are easy to make , no hassle and friendly reminder a day before to confirm. These dental assistant girls are just superb, taking care of you, everything for the patients, keep you well informed, smile and just make you feel at ease and comfortable througout your visit. Dr. Block is the nicest, old school professional who cares for you like you were th most special person in the world. I never experienced pain or discomfort, he knows the thourough ways to keep you informed, pain free and smiling, even through the sounds of the drill. HIghly recommend this cozy little place on Fresh Pond Road. Why, I didnt find them sooner????? Both me and my husband are life long patients here from now on. Thank you , Dr. Block and staff. You all rock!

Miralin N. from Corona, NY (Source: Yelp)


I originally went in for an emergency, and the staff here was very nice and fit me in as soon as possible. This was about 6 months ago, since then I have had several visits to fix some problems that were overdue, and the doctor and everyone there was always very friendly and it was a very pleasant experience. I used to fear going to the dentist, hadn’t gone in over 7 years because of a bad experience, but now I will be sure to always go here. I have recommended them to all of my friends too. It’s affordable and the doctor always makes sure you are comfortable and explains anything you want to know about the procedures.

Erica U. from Brooklyn, NY (Source: Yelp)


I am very happy with the service I received at this office! I hadn’t been to the dentist in a long time and they were very patient and understanding. They took time to review different options with as far as maintaining the amazing cleaning they gave me.  They were also very understanding with the different insurance plan I was on and were able to accomodate me.  I would highly recommend this dentist office to anyone.  Very clean and friendly environment!

Today was my second appointment at PFD. The staff really lives up to their name. Everyone is friendly and understanding. I’m somewhat of a nervous patient, but the doctor and their team put me right at ease. Bedside manner is important and not always present at dental offices. Rest assured you will be in good hands under their care. I went in for a number of issues and was given a treatment plan which not only works for my schedule but for my budget as well. I went in feeling nervous and left feeling confident. I highly recommend Patient Friendly Dental.

Great Dental practice! The staff is polite friendly and will go above and beyond to help the client. The location is easily accessible and near public transportation. The Doctor and Assistant were gentle and completely open to helping in what ever way they could. One of the best Dental experiences and I great appreciative of their work!

Christian C. from New York, NY (Source: Yelp)


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!

I have went to this place and doctor Lina is one of the great doctor I have ever met in my entire life she took care of me and did all the x Ray and because I had some serious problems with my tooth she referred me to the different doctor and than she contacted me later on and refunded what she charged me I didn’t like to take refund but I am not working right now thats the only reason I have took it but I would definitely recommend doctor lina she’s a great doctor.

Amazing experience for my child. They took such good care of her and let me stand around (with all Covid precautions in place). Very informative, helpful, professional and super friendly. Beautiful office, state of the art equipment and dazzling waiting room. I’m just now realizing that we were the only client in the entire practice and we got all of their attention. I believe this is their post Covid routine, which is super safe (no others around) and very accommodating. We had the whole office to ourselves!!! Now, that’s service!! I highly recommend for adults and children.

Love this place and will definitely be returning. The entire staff was welcoming, professional and they kept us informed throughout our visit. We went as a family: my husband, two boys and myself and they made the experience educational, engaging and fun for my boys. I really appreciated that they were able to book us all for the same time slot. I’ve already shared their information with my friend and will continue to share. Thank you!!!

Margie M. from RIDGEWOOD, NY (Source: Yelp)


Excellent Dentist Dr Block such super professional listen well to his patients he is open late a few days a week to accommodate working folks and even takes appointments on Saturday’s . They never keep you waiting and stick to their appointments very well .. Absolutely love this Dentist !!!! Ahhhhh-mazing office manager ( sandy ) extremely nice super professional … The staff are friendly as well

Reshma S. from Queens, Queens, NY (Source: Yelp)


I absolutely love this place. They’ve saved my teeth and now I am able to eat and brush without pain, swelling, and bleeding. I would never go to another place for my dental needs. The staff is always alert and know how to make you feel welcomed and never unsure about anything. I have recommended all my patients from the pharmacy who experience horror stories at other facilities to go check them out. They take their time and never rush. I don’t care if I am there for over 3+ hours, I know will be walking out with amazing results. Go and see for yourself, you will not be disappointed.

I was having pain and needed to go in for an emergency extraction Dr Block saw me the same day, I was in and out in and hour and half. The staff was very attentive, professional and friendly. Dr. Block did a great job, I didn’t have any pain, the extraction was the smoothest I ever had. Awesome service, thanks to the staff you made the dentist a pleasant experience.

They took me in as an emergency case last minute during a Saturday afternoon on a holiday weekend when no dentists would see me. I had an emergency situation with an infection spreading up my face. It was handled promptly with great professionalism and extra effort into making sure my aftercare would go smoothly..I’d recommend to anyone.. 10 stars if it was an option

Christiano E. from RIDGEWOOD, NY (Source: Yelp)


Dr. Block is the best, did a great job cleaning my teeth. The crew are awesome as well, friendly and professional, they answered all my questions and followed up after a couple of days how was my post bleaching session. Also worked well with my schedule and even opened a little earlier for me. I highly recommend this dental office!

Kristin L. from Franklin Square, NY (Source: Yelp)


I have been going to Dr. Dennis Block for 40+ years. Even when I moved away from Ridgewood, I had attempted to try to see Dentists closer to my new location. I never stayed with them and always went right back to Dr. Block! No one is ever particularly “excited” to go to the Dentist, some people are downright frightened of Dentists! Dr.Block is a pleasure to visit. It is not “scary” or painful. He is the best Dentist. His staff is always helpful, curtious and very professional. I highly recommend Patient Friendly Dental

Erica A. from Far Rockaway, NY (Source: Yelp)


I LOVE this place. The staff treats you like family, Dr. Block is very attentive and compassionate, his expertise is awesome, and the prices are great. I never have a complaint when I go. The appointments are always on time, and my treatment is always worry-free. I can’t say enough about this office.  Dr. Block is definitely the dentist you wanna see.

Pamela M. from Brooklyn, NY (Source: Yelp)


Growing up I always had problems with my teeth which made me grow to hate the dentist. Dr. Block and his team DEFINITELY made that change for me, they are all nothing but sweet and welcoming. They made my visit so much better, I actually didn’t mind coming to the dentist after a while because they made me feel so welcomed, always joking and very talkative. PLUS on top of that Dr. Block’s work is amazing, I had to get a bridge done and it’s perfect I can’t stop smiling. He made sure it was legitimately perfect before he sent me on my way and put me on recall. HANDS DOWN BEST DENTIST AND STAFF!!

Robbie T. from Flushing, NY (Source: Yelp)


Everything about this was awesome, helped me even though I didn’t have insurance, everyone is super friendly, Doctor was very knowledgeable, friendly, and gentile!  Worked with me on payment options since I didn’t have insurance… this is the first time I’ve gone to the dentist on my own and I’m so happy I found the best in Ridgewood!

Morgan Acheson (Source: Google)


I had not been to the dentist in some time due to a horrible experience years and years ago. I was riddled with fear and shame and then couldn’t wait another minute. I was met with overwhelming kindness, understanding, and incredible professionalism. I was told “you’re in control. If it starts to bother you just raise a hand and we will take a break”. I’m actually looking forward to my continuing treatment as I know I’m in the best of hands and I’m just so looking forward to not being anxious about my dental health any longer.

Friedhelm A. from Whitestone, NY (Source: Yelp)


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.

Jenny T. from New Hyde Park, NY (Source: Yelp)


This dental office is a great and I would definitely continue coming here for all my future appointments! All the workers here are so kind and helpful! The office is neat and tidy which provides for a good atmosphere! The service provided is quick so you won’t have to wait too long to get attended to! The doctors and assistants help you as best as they can so that you can have the beautiful teeth you want to have!

C M. from Millerton, NY (Source: Yelp)


My Wife and I have bee going to Doctor Block’s for almost 8 years, Everyone at the office is professional and friendly, I typically go for cleanings, but last year I broke a tooth and Dr Block saw me immediately and fitted a crown. Even though we moved from Ridgewood to Dutchess county in 2012 we drive the two hours tol attend this office, as we are extremly happy with the care we recieve.

Charlie H. from New York, NY (Source: Yelp)


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!

This place and everyone in it is a true gem. I was met with a friendly and genuine welcome the moment I came in and was treated with such care, concern and kindness by Doctor Koffman. It took a long time to find a great dentist and I couldn’t be happier that I found Patient Friendly Dental. You have a lifelong patient! I can’t wait for my next cleaning 🙂

Rosemary H. from New York, NY (Source: Yelp)


On August  27 I went to Dr. Block office for the first time.  Sandy was so friendly and nice.  I was in a lot of pain cause I had a mouth infection so I could barely open my mouth.  I was seen by the dental assistant Ilona and she took an x-ray.  Even though she knew I couldn’t open my mouth she was sympathetic and took in slow.  Then Dr. Block came in and looked in my mouth and knew where I was in pain.  He was very gentle with me. I was also shown a video on the procedure I had to come back for.  That was a root canal.   On Sept 3 I had a root canal.  A day later I felt no pain.  I was able to eat.  The procedure was uncomfortable but I felt NO PAIN.  Dr. Block brings in specialist to do root canals and he checks up on you after the procedure.  Both the dental assistant and the specialist consistently asked if I was okay.  Today Sept 17 I went for my temporary crown. The dental assistant  Ilona did cleaning of my teeth.  It was a little painful, but she went slow and careful if I complained.  She was so friendly and sympathetic to me. When I was ready for my temporary crown to get done Dr. Block came in and numbed me and I felt NO PAIN just a little discomfort.    After the procedure I was shown a video on what to do in taking care of my temporary crown.  I only have one more visit on Oct 1 to get my porcelain crown.  I would recommend this dentist if you are scared to go to the dentist.  He is gentle and caring and makes you feel as comfortable as possible when working on your teeth.  I can’t say enough about the staff.  They are sooo nice and they make you feel welcome and at home.  Sandy gave me the remote to watch Netflix.  That was cool.  Anytime I need any dental work done this is the place I will go to.  I found my home here.
