Why Choose North Shore Dental Group
The #1 Dental Practice in Manhasset, NY — By Far.
North Shore Dental Group is a private multi-specialty dental practice. Since 1947, we've been the dentist of choice for discerning patients across Manhasset, Great Neck, Port Washington, Roslyn, Plandome, New York City, Queens, Westchester, New Jersey, Connecticut, and the entire Tristate area. Because our adult providers are out-of-network with all insurance plans, every clinical decision is made by your doctor — not by an insurance reimbursement schedule. That means the highest quality care, the finest materials, and the time every case deserves. We still happily accept out-of-network benefits, our fees are among the most reasonable in the area for this caliber of care, and you get exactly what you pay for — never worrying about cut corners or a compromised standard.
A True One-Stop Shop for Every Dental Need
Most dental offices send you somewhere else the moment your care gets complex. We don't. From your child's very first cleaning to full-arch implant rehabilitation in your eighties, everything you need is handled in one location, by one coordinated team who already knows your full history. Hygienists, general and cosmetic dentists, a board-certified periodontist, a Harvard-trained prosthodontist, and two pediatric dentists collaborate on every plan — so you're never bouncing between strangers, repeating your story, or driving across the Island to finish what was started here.
Our team includes experienced dental hygienists, general dentists, cosmetic dentists, and board-certified specialists — all under one roof. You get gentle, meticulous cleanings and specialist-level restorative, cosmetic, periodontal, prosthodontic, and pediatric care from the same team that knows you by name.
Cleanings, exams, fillings, crowns, bridges, veneers, whitening, smile makeovers, dental implants, full-mouth rehabilitation, periodontal surgery, gum grafting, dentures, pediatric dentistry, and emergency care — handled in-house at 450 Plandome Road, with free private parking.
For the rare procedures we don't perform in-house — endodontics (root canals), orthodontics, oral & maxillofacial surgery, TMJ, and sleep apnea — we refer only to the most respected board-certified specialists on Long Island and in NYC. After 75+ years here, we know exactly which specialist is the best in the area, and they take our patients first.
Dr. Monica Tanna, our Board Certified Pediatric Dentist and Diplomate of the American Board of Pediatric Dentistry, is in-network with most major insurance plans — making top-tier pediatric dental care affordable for Manhasset families. From a child's very first visit through their teenage years, your kids are in the best hands on Long Island.
Patients consistently rate us 5 stars on Google, with hundreds of reviews praising our gentle hygienists, world-class specialists, beautiful office, and thoughtful patient care. We don't just claim to be the best dentist in Manhasset — our patients say it for us, every single week.
Manhasset is one of the Tristate area's premier healthcare destinations, home to Northwell Health and world-class medical specialists. Patients already travel here from Manhattan, Queens, Brooklyn, Westchester, New Jersey, and Connecticut for elite medical care — and they trust North Shore Dental Group to deliver the same caliber of dentistry.
Our doctors trained at the most prestigious dental schools and academic medical centers in the country. Dr. Seiichi Yamano (Harvard / NYU prosthodontics, NYU Associate Professor), Dr. Effie Ahladiotis (Tufts / Columbia periodontics), Dr. Jeannine Weiss (Pediatric Program Director, Jamaica Hospital), and more — collaborating on every case.
Pearl AI X-ray analysis, digital radiography, intra-oral cameras, nitrous oxide for relaxation, and two premium in-office whitening systems — Philips Zoom and Smyle. Modern technology, used to give you better outcomes, clearer answers, and a more comfortable visit.
Our adult providers are out-of-network with all insurance plans — and that's exactly why patients choose us. It frees us to use the finest materials, the most advanced techniques, and the time every case truly deserves. We still happily accept out-of-network benefits, our fees are among the most reasonable in the area for this caliber of care, and you get exactly what you pay for — with the peace of mind of knowing nothing was ever compromised.
Manhasset's Premier Specialty Referral Network — Endodontics, Orthodontics, Oral Surgery & Beyond
For the small handful of procedures that aren't performed in-house, we refer to a hand-selected network of the most respected board-certified specialists in Manhasset, Long Island, and New York City.

In the Center of Manhasset — Where the Tristate Comes for Healthcare
Patients already travel to Manhasset from Manhattan, Queens, Brooklyn, Long Island, Westchester, New Jersey, and Connecticut for the most respected medical specialists in the region. North Shore Dental Group sits right in the middle of that healthcare community at 450 Plandome Road — making it natural to combine a dental visit with other medical appointments, or to make a single trip from the city for the best specialist-level dental care available anywhere on Long Island. When patients say they drive an hour past dozens of other dentists to come to us, this is why.
