I’ve been going to WorldWide Plaza Dental for a few years. Every time I leave, I feel an immense sense of gratitude for Dr. DeBonis and his team. From The receptionist; Yolanda to the Hygenist; Thays…Dr’s dental assistant (blanking on her name) but she’s the best! The entire staff here is extremely welcoming! I’ve been here about three times during the pandemic and I have to say, they are in line with CDC precautions during COVID to the T and then some! Dr. DeBonis and his team make going to the dentist not so bad, scratch that, not bad at all!

Very caring and convenient dentist in Hell’s Kitchen. After my last dentist sold out to some big chain a few years ago I’ve been coming here ever since. I should have just started here to begin with because the level of personal attention is just much higher. I’ve never had anything other than routine cleanings 2x a year but I feel like if I needed something I’d be very comfortable coming here for care.

Dr. DeBonis has been my dentist for more than twenty years. I have had dental insurance that whole time, but unfortunately it is not accepted by Worldwide Dental. Nevertheless, I am so pleased with my treatment here that I would rather spend my own funds instead of going somewhere else where my insurance is accepted — and I can’t think of a stronger endorsement than that.

Dr. Debonis and his staff are the best dentist/ staff office I have ever been to. I have had extensive dental work since a bumper car accident as a child left me with a myriad of issue with my teeth. So I never liked going to the dentist…..but with Dr. Debonis it is different, he is so calm and caring that I look forward to going to the dentist now!!! Thank you Dr Debonis, Val and all the staff, for always making my visits pleasant. I highly recommend Dr. Debonis.

I have been going to World Wide Plaza Dental for many years because Dr. Debonis, his assistant Val and the entire staff are skilled, experienced, professional and pleasant. I recently had a tooth shaved for my first time and couldn’t be happier with the result! Dr. Debonis spent a considerable amount of his time to make sure he shaved off just enough (not too much) while also making sure to shape the tooth in a complimentary way to the neighboring teeth. I highly recommend him for any dentistry work!

Adam W. from Financial District, Manhattan, NY (Source: Yelp)


Dr. DeBonis was excellent – incredibly thorough and took his time to give me dental advice. Answered all my questions and was very knowledgeable. I don’t enjoy going to the dentist but I did enjoy my time here. There may be a bit of a wait, but that’s because they take their time with each and every patient to make sure they receive quality care. I’m glad I switched to the dentist half my office goes to.

Cara S. from New York, NY (Source: Yelp)


Everyone here is incredibly friendly and knowledgable. I was nervous about finding a new dentist after moving to the area, but everyone here put me at ease. I usually am very nervous and sensitive about going to the dentist, but they have made me feel very comfortable during my visits. This is the perfect place for people who are scared of going to the dentist.

I’ve been going here for years and every employee I’ve encountered has been friendly, professional, and extremely competent. The bedside manner is phenomenal, and they take great care of you. I continue to go here even though I’ve moved. I just went in March 2021 and the COVID protocols and precautions were very impressive. I felt very safe and got great care.

From the moment I met Dr. Debonis and his dental assistant, I knew I was in good hands. He is thorough, taking the time needed to fully assess my dental condition and make astute observations. He listened to my concerns, took full x-rays and assessed the work that I need done. It was an in-depth consultation, making me feel confident that I could trust Dr. Debonis to do excellent work j

Karen D. from New York, NY (Source: Yelp)


This was my second visit to WWP Dental and I have to tell you that I am thrilled.  A great dentist is hard to find and now that I have found him I will continue going there. The staff is absolutely amazing.  EVERYONE is friendly and professional.  Dr. DeBonis and his staff really make you feel welcome.  Dr. DeBonis is very knowledgeable and discusses all options, pros and cons. I am very happy to have discovered this office

Celia S. from Manhattan, NY (Source: Yelp)


I got there totally scared due to prior dentists… Dr. DeBonis calmed me down before going through anything else. He CARES and shows it. He took care of me with professionalism, and a lot of patience. He explained everything to me and was super gentle through the very end. I loved the classical music behind too! It helps relax. He has the best staff ever! I loooove Dr.DeBonis and I’m looking forward my next visit!

Tina Kim (Source: Google)


I was due for a much needed dental appointment and couldn’t wait out COVID much longer. Everyone at the office is super cautions and have strict protocols to ensure everyone is safe and at ease. The team was super friendly and Dr. DeBonis was very thorough and went over the status of my dental health. Overall great experience!!

Linnet T. from Larchmont, NY (Source: Yelp)


Outstanding dentist!  I have been a patient of Dr. DeBonis for decades.  Even when we were living in London for a few years, I still came back for my dental check-ups.  He is a very careful and skillful dentist. He takes great care in figuring out the best way to address dental issues while minimizing the impact on your existing teeth. I have poor teeth, and am very sensitive to pain. I wouldn’t dream of going any where else!

Todd M. from New York, NY (Source: Yelp)


I’ve been a patient of Dr Debonis’ for the last six years and I could not recommend him or his staff more highly.  The quality of their care is top notch, and their bedside manner puts most others in the medical field to shame.  I appreciate the time Dr Debonis takes to explain procedures, the effort he puts into remembering his patients, and his willingness to see you immediately in emergency situations.  It’s little mystery why so many of my friends are also Dr Debonis regulars and have been for years!

May D. from Pawling, NY (Source: Yelp)


I think I finally found my dentist! A colleague of mine recommend Dr. DeBonis and I am glad I took his recommendation! I hate going to the dentist…so much so I haven’t gone in over two years. After seeing Dr. DeBonis for the first time today, I am no longer hesitant to keep my semi-annual dental visits.

I’ve been a patient of Dr. De Bonis for more than 20 years. He is always patient, explains procedures, is concerned about my comfort level with any procedure, and as someone who’s afraid of going to the dentist, I know that I have nothing to fear in his dental chair. I can recommend him and his wonderful Dental Assistant Valerie Volmer 100%.

John S. from Manhattan, NY (Source: Yelp)


Dr. DeBonis is the dentist I have been looking for my whole life. He is brilliant, friendly, thorough. He is passionate about dentistry and engages his patients in an interesting conversation as he doing his examination — he explains to you the relevance of what he is doing, so that you understand the importance (e.g., flossing). He also teaches you how to floss and gives you a helpful tip that is worth the price of the examination! I am on Aetna, and my cleaning/xrays were 100% covered.

Karen Mok (Source: Google)


Dr. De Bonis is really great and so experienced. He does his best to assuage your concerns and makes sure you feel comfortable during the whole cleaning process. He stays up-to-date with the current dental research. He explains everything really well – including what you may be doing correctly or incorrectly in your dental hygiene routine. At the end of the appointment, he also gives you the materials necessary to make sure you succeed in maintaining your oral hygiene. I highly recommend!

Every visit to see this team is wonderful. Can’t recommend highly enough! The care and personal attention is the best I’ve ever experienced with a dentist team. I always feel valued and they have great advice and make you feel like they genuinely have your best interests at heart! Thank you Dr. DeBonis and team!

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


I have had a fear of dentists since childhood. I searched a long time to find the right dentist. When I found Dr William DeBonis I knew he was the ONE! He is a very competent dentist but also a kind and gentle professional. He listens to your concerns and takes his time to do a complete and thorough examination and treatment. His entire staff is friendly, helpful and efficient. I can’t say enough good things about my experience with Dr Debonis at Worldwide Plaza Dental. I have been with him about 10 years now. I refer everyone to him when they need a dentist.

Geraldine A. from Provincetown, MA (Source: Yelp)


Dr. DeBonis is fantastic: kind, attentive, and professional. He bends over backwards to make sure his patients are satisfied. The staff is terrific. I am so fortunate to have picked him from the many recommendations I got. He’s also very well connected in the Dental Community, and had me at an oral surgeon within an hour of diagnosing a huge problem with my molar. Its pretty crazy to look forward to going to the dentist, but that’s what happens when my appointment approaches!

Austin T (Source: Zocdoc)


This was the best Dental practice I’ve ever been to. The staff was very cautious with Coronavirus protocols, and clear to outline their procedures. The technician was friendly, talkative, informative, and efficient. Dr. Debonis did an incredible job at informing me of tips, tricks, and techniques for ensuring good dental health. The doctor even walked me through each X-ray photo to explain what we were seeing and was keen to point out any areas of concern he had. I will be returning to Dr. Debonis for as long as I can, everyone in the office was exceptionally friendly and I highly recommend it to anyone looking for a new practice.

Alan L. from Manhattan, NY (Source: Yelp)


I can’t say enough good things about Dr. Debonis and the staff at Worldwide Plaza Dental. When I first moved to NY in the mid-90s I had a series of dentists… and had a miserable experience with each one. Then a work colleague recommended Dr. Debonis, and I havent looked back since. Dr. Debonis does excellent work. He is super personable and knows his stuff. After just a couple of minutes with him you get the sense that he really knows what he is doing. More importantly, he’s got me to better my dental habits with lecturing or hectoring. The staff at the office are all great to work with and very friendly and professional – quite a difference from the usual bureaucratic medical offices. I’ve recommended Dr. Debonis to everyone that’s asked – I wish more of the dentists were like the good doc!

Lee F. from New York, NY (Source: Google)


Excellent treatment and service all around – from Admin Staff and appointments, to Hygienist, and finally sitting in Dr. Will’s chair with his Assist Val attending. Dr. DeBonis and his Team have been my Dentist for several years. I always leave in better condition than when I arrived, and I continue to learn more about what I can do to manage my dental hygiene as I age! Would not consider going anywhere else! I did not have Dental Insurance one of the 6 years I have been a patient, and it still was perfectly reasonable.

Rebecca P. from Manhattan, NY (Source: Yelp)


I had my first appointment with Dr De Bonis a few weeks ago, and I couldn’t have been more satisfied with the experience. As anxiety-free as a dental visit could be, Dr De Bonis not only does a great job (I had multiple fillings done over a three week period) but is also sensitive to the individual patient and his or her needs. And he even managed to get me excited about flossing!

Edgar C. from Dallas, TX (Source: Yelp)


I’ve been going to Dr. Debonis (Will) since the late 1980’s. He’s an excellent dentist. A couple of complicated fillings he did 20 years ago are still in great shape, as is a crown he put on 12 years ago. His more recent work has been equally excellent, and he keeps current with tooth technology. He’s also a kind, humorous man, with a good chair-side manner. I’ve sent several friends to Dr. Debonis, and they have also been happy with him. The office staff, assistants and dental hygienists have also been helpful and good over the years. I moved to Dallas, TX in July 2013 – and I’m not at all happy about having to trust my teeth to someone else now!

Robert D. from Manhattan, NY (Source: Yelp)


I have been going to Dr. Debonis for the last few years after a recommendation from a coworker.I couldn’t be more thankful to my coworker for this recommendation. Dr Debonis and his staff are so courteous and professional. Nobody really ever enjoys going to the Dentist but this dental office makes the experience as pleasurable as it gets.I would totally recommend Dr.Debonis to anyone in the market for an excellent dentist.

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


My entire family and I have been going to Dr DeBonis since 2006. When I first walked in and saw 3 chairs in the waiting room I thought this guy had no business and if he did it was assembly line treatment. I was so wrong. They are so professional, thorough, and diligent that it almost makes me suspicious. But 7 years later that other shoe has yet to drop. The have caught blunders from our previous dentist and consistently showed a real interest in our family’s dental health. In the universe of health care this practice is a gem.

Just got back from my dental appointment. I was a little nervous about a dental appointment in the Covid era, but the very thorough precautions and protocols really put me at ease. Temperature check, pulse oximeter check, new mask, sanitizing rinses, new equipment to keep the team safe, and even an electrostatic fogger all made me feel quite safe. Alma and Dr. Debonis were their usual professional and competent selves and the rest of the team made the setup and actual visit seamless. As always… a great experience. Thanks!!

Who loves going to the dentist? mostly no one, but I do. I’ve been seeing Dr. DeBonis and his ace team for over 20 years and I truly look forward to my visits. I’ve been twice in the days of Covid and it feels as safe as it can be with protocols in place like no overlap in waiting room, limited in-office staff, masking, air filters and more. Dr. DeBonis is gentle, good at giving shots, communicates well, and fun to talk to when his hands aren’t in your mouth. Most importantly his dental work has been excellent. The whole team is top notch.

Ere H. from Brooklyn, NY (Source: Yelp)


I have been a patient of Dr. Debonis for 12 or 13 years now. Dr. Debonis is  very patient about explaining dental care and the procedures he is doing and extremely adept, I have never had a bad or painful experience in his chair. I have referred a number of my friends to him over the years and they all loved him and were really happy with the service they got and from what I can tell, his price structure is very reasonable. He and his staff are very cool too, which is an added bonus. I would definitely recommend him.

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


I have been a patient of Dr. DeBonis and Worldwide Plaza Dental since 1999 and I could not be happier. I have lost track of all the people I have told about this practice, which includes someone who stayed away from dentists for over 10 years and now feels the very same way. Dr. DeBonis LOVES dentistry and it shows, the practice is professional and caring, up to date with techniques. Bottom line I know I am receiving the best care I possibly could be and doesn’t that say it all. Thank you Dr. DeBonis and everyone at Worldwide Plaza Dental, thanks to you I actually enjoy going to the dentist!

I was very impressed with the detailed explanation Dr DeBonis provides of the issue you might be having and the solution – it’s like bringing you along the journey rather than just doing anything. He has a very patient and calming personality I thought and that’s helpful for someone who is extremely paranoid about visiting a dentist (me!!!).

James T. from Theater District, Manhattan, NY (Source: Yelp)


Like Nathalie, I was in need of a new dentist after moving work locations in Manhattan. Dr. DeBonis handled my first cleaning himself in order to “get to know my teeth” and did a very thorough job. He is also very enthusiastic about teaching dentistry in the simplest terms. My appointment was efficient and answered all of the questions that I had. I had previously been using a dentist who gave me a very small filling for some decay that I never noticed, but after the filling my tooth hurt far worse that before the filling and after several follow up appointments, it still wasn’t fixed. When I went to Dr. DeBonis the and explained this, he noticed that there was a very slight high mark in the filling that was causing pain in my bite at certain points and was able to quickly and painlessly fix the high point, free of charge. I look forward to having a long standing relationship with such an honest Doctor. The staff is also incredibly nice.

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


Dr. DeBonis has been taking care of me since I first came in with a sore wisdom tooth. Since then he has removed my wisdom teeth and provided a couple of much needed fillings. His services are very reasonably priced and his touch with a novocaine needle is light and sure and I never feel any pain when he is working on me. Also, his assistant, Val, is wonderful, smart and great at calming me down (we all get pre-dental work jitters, right?). I recommend Dr. DeBonis to all my friends and to all of you!
