Multi-specialty dentistry on the Upper East Side
Smyleee Rating
Very Good
Upper East Smiles is a multi-specialty dental practice located at 261 East 78th Street in the Upper East Side neighborhood of Manhattan. The practice offers general dentistry, periodontal care, Invisalign, and a range of specialty services from a conveniently located office in the residential heart of the Upper East Side.
Preventive care services include professional dental cleanings and comprehensive oral health examinations. The clinical team includes general dentists and Dr. Liss, a periodontist who provides specialized periodontal assessments and treatment within the same practice. This integrated model means patients can receive periodontal care alongside routine dental maintenance without a separate referral to an outside specialist.
Invisalign clear aligner treatment is offered for patients seeking orthodontic correction. The in-house Invisalign process covers consultation, treatment planning, tray delivery, and monitoring throughout the treatment course. CT scanning is available for diagnostic purposes. Multiple dentists at the practice—including Dr. Lisa Chen and Dr. Haesun Souh—provide general dental care, and each takes time to explain findings in accessible terms and to address patient concerns at each visit.
The practice operates across two locations, which allows patients to maintain continuity of care with their preferred providers across both sites. The team at the East 78th Street location is noted for attentiveness and thoroughness—new patients describe clearly explained treatment options, respectful interactions, and efficient appointment management from check-in to checkout.
261 East 78th Street is located in the heart of the Upper East Side residential neighborhood, close to Lenox Hill Hospital and the 6 train at 77th Street station. The practice serves patients from the East 70s and 80s, Carnegie Hill, and the Yorkville stretch of the Upper East Side. The M79 crosstown bus provides east-west access across the Upper East Side to the building, making it accessible from both the Lexington and Second Avenue corridors.

I’ve been a patient for several years. It’s so helpful to have all specialists under one practice. Dr. Liss, a periodontist, is so friendly, thorough, and knowledgeable. She follows up on her patients and is extremely kind. I have also had Invisalign here which was a seamless process with great results. Highly recommend the practice at both locations.
From check-in to checkout, my experience was excellent. The hygienist was very thorough, and Dr. Lisa Chen explained our situation in a way that was easy to understand. She was gentle, patient and professional. We appreciated how caring everyone was. Friendly staff, clean office, and excellent dental care. Highly recommend!
This was my first time visiting. The clinic was clean, and pleasant. Everyone was very nice, specially Kathy who was assisting was so sweet. Dr. Liz was also very kind and competent. Thank you for also for doing the CT scanning for free. I greatly appreciate it. Thank you so much. Jane
Excellent staff and provider! I was seen promptly, treated with respect and all my concerns addressed. The ladies at the front desk were very helpful and my dental hygienist was kind and gentle. My dentist Dr. Haesun Souh was thorough and had a great bedside manner. The office is well managed and clean. I highly recommend this practice!
I don’t think many people would say how much they love going to the doctor or dentist! But this dental practice is truly very professional, responsive and patient- centered. The entire team is professional and of course I am grateful to be under the care of Dr. H. Souh. She makes going to the dentist such a pleasant experience. She patiently listens to her patient’s concern and takes the time to explain.
