“Dr. Dayani took the time to explain my current dental condition, octopus, listening to me, complicated dental history and making sure I got the right CAT scans done. He reviewed the CAT scans with me, and did not try to oversell me on any treatment. He kindly provided me with a referral for someone who would best be able to manage the complications I’ve been experiencing due to the work of another surgeon .? I was able to get in to see him very quickly using Zocdoc, less than 24 hours. He did not rush, and was patient with my questions.”

“Even before I showed up at the office, I knew I had chosen the right place.
Staff was in constant contact with me and advised me on how to prepare for my appointment.
When I got there, paperwork and formalities were taken care of and I saw Dr. Dayani right away.
For the next 2 hours I sat in the dentist chair and Dr. Dayani orchestrated the diagnosis and treatment like a concert maestro; effortlessly and painless.
The assisting staff were professional and charming, and I left there with a smile.”

First of all being left in the chair for over an hour before I was seen I should have walked out! The way the dentist spoke to his assistant through out the time I was there was an absolute disgrace. She may have been new but he was no help to here and spoke in an awful tone! Used my maximum insurance allowance in 2 visits also where now I am out of pocket for the rest of the year! I really regret going to this “practice “ and anyone that wishes to go here please reconsider!

An exceptionally knowledgeable doctor! He provided me with all the information I needed, listened attentively, and thoroughly answered all my questions. Unlike many other dentists in the city who seem focused solely on profit, he truly prioritizes patient care. I would highly recommend my friends to book their next appointment with him.

This office was extremely finicky with my appointment. Multiple times the day of they tried to get me to cancel. I had a pleasant visit last time but based on this difficulty I will not be rebooking.

I am so satisfied and extremely happy with the services that have been provided. Tara really went over and above to ensure payment, information was submitted to the insurance.
Dr. Dayani explains what he is going to do, asks if you have questions. Honestly, I couldn’t be happier and Satisfied with any other doctor.

Dr Dayani has taken great care of my teeth since I switched to his clinic a few years ago. His attention to detail far exceeds what I have experienced elsewhere and I fully trust his him.
More than 1 year agoNK
Dr. Dayani has always been wonderful. He’s easy to make appointments with and has been willing to see me on no notice for emergencies. He once performed a shockingly painless and easy root canal on a difficult area of a wisdom tooth. Most would have given up and pulled the tooth, but he did a fantastic job, saved the tooth and stabilized the whole area. It’s a huge pleasure to recommend him for all your toothy needs!

Dr. Dayani is great at what he does. He is very thorough, careful, and patient with his work, constantly checking to make sure I was comfortable throughout the process. He is honest and transparent, and you can tell he actually cares about his patients. Rather than saying “you should do this,” he explains all of your options, pros, cons, and costs of each option, and is careful with his recommendations. I’ve never felt this level of trust and confidence with any other medical professional - I highly recommend him and his team.
More than 1 year agoJC
I had to get a root canal and was incredibly anxious, as I’m terrified of dental work. Dr. Dayani was amazing—he was extremely patient and took the time to make sure I felt comfortable throughout the entire procedure. Despite my fear, he helped me get through it without sedation, and I truly felt like I was in good hands. I highly recommend Dr. Dayani for anyone who’s nervous about dental work. His calm and reassuring approach made a huge difference for me!
More than 1 year agoCS
I had a wonderful experience with Dr. Dayani. I came in concerned about the amount of dental work I needed to have done. He was incredibly kind and explained in thorough detail what my treatment plan would be, how he plans to approach my concerns and incorporated my feedback in the plan of action. I left my appointment feeling relieved that there were solution to my dental concerns. I will definitely be back.

Dr Dayani is very professional and compassionate. He treated me as an individual. And I am not easy. I would recommend him highly to anyone with anxiety or pain tolerance issues, especially. ..and obviously to everyone with dental care needs.
More than 1 year agoLR
I had an excellent experience with Dr. Dayani! I was in a lot of pain and swelling, but he saw me right away. He was incredibly nice and made me feel comfortable. After the procedure, he continued to check in with me to see how I was feeling, which really showed how much he cares about his patients. The whole process was smooth and pain-free, and I couldn't be happier with the results. I highly recommend Dr. Dayani to anyone looking for a caring and skilled dentist. Thank you so much, Dr. Dayani!

Dr. Dayani took his time to explain the procedures and answered all my questions. He was very patient and made sure I was well informed about everything from the process, to insurance coverage. He was highly professional at all times and easily reachable for follow-ups. I came in for a complicated root canal and crown. Dr. Dayani was very thorough and made it as comfortable of an experience as possible in this situation.
More than 1 year agoEM
Dr. Dayani was the most thorough and helpful dentist I’ve ever visited. I was seen right away when I arrived. He explained every step of the experience and the images taken. He was very careful to check on my comfort level during the procedures. He took extra time to explain possible treatment options during and at the end of the appointment.

Awesome
April 3, 2023Thomas M.Verified patient
I had gone in with a terrible dental ache and a swollen face, Dr and the staff were very attentive and made extra efforts in order to make sure I was calm and my problems were addressed. Communication was great and all my questions, doubts and worries were answered patiently and in detail. What’s also great is that the Doctor is available after hours to answer any of your concerns you may have and addresses your concerns promptly and makes me aware of what the possible dental solutions are, which is the best option/route to pick, what to expect during the procedure and after. I am thankful that they made one of the most painful events of my life quite manageable and provided prompt services and were very accommodating.
February 22, 2023Vidhi S.Verified patient
Dr. Dayani came highly recommended by my very discerning general dentist so I had high expectations of his technical skills. But I was not prepared for how Dr. Dayani took the time to explain all my treatment options and likely outcomes so that I could be sure that my choice was the best one for me at this time. I am so grateful for his patience and exacting care, both very rare qualities.

In terms of quality of work, he is top notch. His assistants are very nice. Unfortunately, his front desk seems fairly unorganized borderlining on incompetent.

I have a fear of dentists that stems from my childhood. After realizing I could not afford to continue avoiding taking care of my oral health, I took a chance and booked an appointment with Dr. Dayani and I was glad I did! Not only was her very understanding, he also took his time to thoroughly explain both a short term and long term plan to get me back in good health. If you’re like me and fear the dentist chair, do yourself a favor and put your trust in Dr. Dayani and his care team.

I had a new patient visit and had a great visit and this is coming from someone that has a fear of going to the dentist. It took longer than expected, but that was due to a person coming in for an emergency apt. They took time to make sure my insurance covered everything and overall felt I was in good hands.

This place is very unprofessional. The nurse tried multiple times and finally gave me the correct forms to fill. They cannot even figure out what's covered in my plan or not. They also tend to cheat me to do a full x-ray exam although I was just go for a regular preventative teeth clean. I don't know whether this organization meet some problem in operation or it always do the business in this way. I'd recommend avoid this place.

I went for second opinion. He explained everything you want to know about your condition and possible solutions better than any other dentists. Highly recommends.

Dr. Dayani's office was kind enough to squeeze me in for an urgent last-minute visit at 5PM. He is knowledgeable and correctly diagnosed the cause of my tooth pain, and even helped contact an oral surgeons office on my behalf.
July 3, 2019Initials hidden
I went for a very superficial cosmetic treatment -- a minor scrap on the back of my front tooth that needed a simple bonding. Instead he started scraping away at other cosmetic work I had done and said there was an underlying problem and needed X-rays, which I flatly refused. I also had a hard time understanding him through his heavy accent and he was getting angry and talked louder. I had the work done elsewhere no problem.
June 4, 2019Nelson M.Verified patient
He seemed to be rushing it and not in a good mood that day. First doctor I saw who didn’t care to smile a little during whole visit. I can even call him a bit rude... May be just that day... I don’t know... didn’t appear too nice to the people in his office too. They told me at the end that some other doctor will be helping me and I will have to come back at a later date which they should have told me in the beginning. Overall below average experience.

Had to cancel my first appointment because they were running 2 hours behind, then this one they were running an hour and a half behind. Not very professional staff. The doctor was very nice but having to wait so long (despite me asking multiple times and being assured it would be any minute...) was unacceptable.
February 4, 2019Renee L.Verified patient
Dr. Dayani and his associate Luis were able to fit me in on a Friday while I was visiting NYC during the holiday week. He’s one of the best dentists I have ever seen. They were attentive, thoughtful, made sure they understood my needs, and gave me a first rate exam and cleaning. Dr. Dayani correctly described my dental history. He was attentive to pain management (I didn’t need it, but I appreciated that). He gave very clear explanations about what was going on with my dental health.
December 28, 2018Christopher T.Verified patient
Dr. Dayani is one of the most caring, professional doctors I've ever met. From the minute I walked in to the moment I left, I felt completely comfortable and informed. From a personal standpoint, he brought me in as a new patient and made me feel like we knew each other for years, and from a procedural standpoint, he made my root canal feel like a piece of cake! Dr. Dayani is a rare talent and I 100% recommend to all!

December 18, 2018Dominic G.Verified patient
Had an excellent first visit. The Dr. And his staff were all very professional and very polite. The offices are beautiful; very clean with very modern equipment. The procedure went so smoothly I could have fallen asleep. Very happy with Dr. Dayani so far.
October 16, 2018Gareth W.Verified patient
I hadn’t been to get my teeth checked in 4 years. I had a lump under my jawline as well as next to my ear and was in pain. Dr. Nima was very welcoming and really took the time to explain to me everything that was happening within my mouth, as well as a few options for what he thinks I should do going forward. He was very knowledgeable and will definitely be visiting his office again
More than 1 year agoJanine G.Verified patient
The best medical experience I've ever had. If you need cleanings or something more complicated, like root canals etc., Dr. Dayani is superb. He is fantastic (I had very complex work that needed to be done) and kind, can't recommend him enough.

Dr. Dayani really is a true professional: thorough, yet easily understandable medical explanations, a great sense of humor and overall compassion for his patients.
