30 Years, One Smithtown Address: Inside Center for Cosmetic Dentistry's Kois-Trained Approach to Smile Design
Drs. Mitchell Shapiro and Michael Palmieri have built a Long Island practice around science-based cosmetic dentistry, a 4.9-star reputation across 737 reviews, and a perfect 100 Dental.me Score.
SMITHTOWN, NY — November 13, 2026

SMITHTOWN, NY — For three decades, one address on Route 111 has been where Long Islanders go when they want a smile fixed right the first time. Center for Cosmetic Dentistry, led by Dr. Mitchell Shapiro and Dr. Michael Palmieri, has quietly become a fixture of the Smithtown community, earning a 4.9-star average across 737 reviews and a Dental.me Score of 100 — a rare, top-tier mark that reflects sustained patient trust rather than a single good month.
A Philosophy Built on Restraint, Not Volume
What separates this practice from the high-turnover model so many patients have come to dread is a deliberate refusal to overtreat. The team describes itself plainly as not a "drill and fill" office — a philosophy that shows up in how cases are planned, not just how they're marketed. Every new patient is offered a complimentary consultation, including limited diagnostic x-rays, before any treatment is proposed. For a cosmetic-focused practice that could easily upsell, that commitment to earning trust first is a telling signal of how Shapiro, Palmieri, and their team actually operate.
Kois-Level Training Behind the Chair
The clinical backbone of the practice is advanced Kois training, a credential associated with a comprehensive, science-based approach to dentistry that goes well beyond surface-level aesthetics. Every treatment plan at Center for Cosmetic Dentistry is built with attention to esthetics, bite mechanics, function, and long-term oral health simultaneously — not cosmetics in isolation. That training proves especially valuable in the practice's most demanding work: full mouth rehabilitation for patients dealing with severe wear, broken or failing teeth, or tooth loss requiring dental implants. It is the difference between a smile that merely looks better on day one and one that is engineered to function and last.
Smile Makeovers, Measured in Thousands
Cosmetic dentistry is the practice's signature strength, and the numbers behind it are substantial — the team has completed thousands of smile makeovers over more than 30 years in the same Long Island community. The range runs from fast, low-intervention fixes, like closing a gap with bonding material in about an hour, to full porcelain veneer transformations and implant-based reconstructions for patients missing teeth. Invisalign is a particular area of focus: the practice offers expedited treatment, with some patients seeing fully straightened results in as little as three months, and currently offers free Invisalign scans along with savings off a patient's first month of treatment. One hygienist-documented case saw a patient achieve straight teeth after 16 weeks of treatment — a pace that reflects how the practice has built its orthodontic protocols around efficiency without sacrificing precision.
Technology That Earns Its Keep
The practice has invested specifically in diagnostic and imaging technology, including digital X-rays, to sharpen diagnostic accuracy, improve clinical safety, and move patients through treatment faster. That technology investment is paired with a genuinely broad service menu for a cosmetic-first practice: general and restorative dentistry, crowns and bridges, gum disease treatment, pediatric dentistry, sleep apnea care, and emergency dental visits are all handled in-house, meaning patients are rarely bounced to outside specialists for routine needs.
A Team That Stays
Longevity defines the staff as much as the doctors. Office Manager Diana brings more than 20 years of dental experience to coordinating patient care and insurance questions. Hygienist Glendy, a Farmingdale State College graduate and member of the American Dental Hygienists' Association and the Long Island Dental Hygienists' Association, has been with the practice since 2013 and is licensed in both local anesthesia and nitrous oxide — credentials aimed squarely at patients with dental anxiety. Fellow hygienist Michelle, a 1987 SUNY Farmingdale graduate also on staff since 2013, carries the same anesthesia and nitrous oxide certifications and is known for treating patients, in her own team's words, "like family." Dental assistant Hilke has spent 20 years in the field, eight of them here, working hands-on with bonding, veneers, crowns, and Invisalign cases. That kind of tenure, across front desk, hygiene, and chairside roles, is unusual in dentistry and shows up directly in the consistency patients describe in their reviews.
That consistency of care is perhaps best captured in the practice's own description of its mission: "At the Center for Cosmetic Dentistry, we are committed to helping each patient receive the treatment they deserve."
Access, Language, and the Patient Experience
The office sees patients Monday and Tuesday from 9:30 AM to 8 PM, Thursday from 8 AM to 6 PM, Friday from 8 AM to 1 PM, and Saturday mornings, with Wednesday and Sunday closed — a schedule built around early mornings and evening hours that accommodate working families. Care is available in both English and Spanish, widening access across Smithtown's diverse community. Patients can pay by cash, check, credit or debit card, or finance treatment through CareCredit, and the practice's emergency responsiveness is already part of its reputation: patients have been worked in as the final appointment of the day after a sudden chip or break, a detail that shows up again and again in patient accounts of the office going out of its way to help.
