I made an appointment for a chipped tooth. Prior to coming in I mentioned I'm on a covid unemployment budget and wanted to know what the costs would be before i sat down, because they do not take insurance at all. The team was aware of my situation, and seemingly knew that I wasn't going to be able to afford it, but insisted i have an evaluation at the cost of $300.00 anyway, only to find out minutes later the simple procedure would be out of my budget. I would not recommend going here.

I have never met such an honest and trustworthy dentist before. I am in the Hamptons for a few weeks and noticed that my tooth started rly hurting. I saw great reviews for this practice and decided to call them. The staff was super friendly and booked me an appointment. I go in and the dentist was completely honest and trustworthy and gave me great advice on how i should handle my tooth situation. He did not charge me for my visit which was amazing. Oh and the place was also super clean! I highly recommend this practice.

Dr. Mambrino returned an emergency call on Thanksgiving morning and got me in Friday morning. The pain from an infected root canal (done elsewhere) not yet sealed was almost unbearable. The doctor took a lot of time cleaning and disinfecting after ascertaining the problem and I walked out of there feeling great. In my humble opinion, he is a great and compassionate doctor.

David and his team are first rate. I lost a cap and couldn't get to my prior dentist so went to EHDG. David was meticulous about insuring the new cap matched my existing teeth. I highly recommend this group and David in particular.

My mouth was a warzone. Heredity & smoking had rendered it a tangle of caps, crowns & bridges, teeth absent in many cases, and my gums extremely compromised. It was time to put my money where my mouth was. Throughout a painstaking (though not painful) process from complete extractions, to surgical bone-grafting, to temporary dentures, to complete implants-- Every step of the way, Dr. Mambrino's & Dr. Nelson's level of expertise, and the extent of their thoughtful care never wavered.

Their support staff is warm, welcoming, and attentive in their caregiving & assisting. The end result for me is a mouthful of full, straight, gleaming teeth-- with which to actually bite, chew, and smile effortlessly, confidently, comfortably-- way beyond my expectations. I experienced "the works" in the dental realm with not a hitch, so I know I can recommend The East Hampton Dental Group without reservation-- for any dental need.

I have been with the dental group for more than 10 years. My entire family is treated by the wonderful Tara. I absolutely love the staff and the new location! Dr. Mambrino fixed a porcelain veneer on my front tooth because it did not look right from the previous doctor. Although sometimes you have a slight wait, that's life. The services they offer are top of the line and execute in a very professional way. Looking forward to a long term relationship.
