Founded in 1979 by Dr. Jan Linhart and joined in 2010 by his son, Dr. Zachary Linhart, our practice blends old-world service and charm with a modern, state-of-the-art environment.
From our origins in NYC’s iconic Helmsley Building to our newer Greenwich and Fairfield locations, we’re known for exceptional cosmetic, restorative, and family dentistry — from smile makeovers to general care. That’s why our patients keep coming back, whether from across the street, or across the world!
She saw misshapen. Misaligned. No longer quite feeling like her youthful smile.
After talking through Invisalign® and PearlinBrite™ whitening, this patient chose porcelain veneers.
20 total, 10 upper and 10 lower.
We broadened the smile and let the incisal edge follow the natural curve of her upper lip, so the whole thing reads as hers, not a stock smile.

The secret to veneers that last 30 years?
Kept clean with regular hygiene visits, that margin can hold up for 15, 20, even 30 years. Let bacteria build up there, and it breaks down much faster.
After your cosmetic case, a few things matter: bite adjustments, consistent cleaning and hygiene, and comprehensive exams.
Veneers are upkept the same way as natural teeth, they just need to be monitored, because anytime we touch a tooth, we’re creating a spot worth watching.
Thinking about veneers in NYC? Here’s the mistake we see most.
Patients come in with a photo of a celebrity smile and ask for exactly that. We understand the inclination. But porcelain veneers aren’t a template you copy onto someone else’s face. The right ones are designed around your tooth shape, face shape, smile width, gum line, and bite.
That’s the difference between veneers people notice and veneers people can’t quite place. The best cosmetic dentistry makes you look like a more rested, more confident version of you.
At Linhart Dentistry, Drs. Jan and Zachary Linhart have been designing custom smiles for 45 years. Still bring your inspiration photos, we love seeing what draws you in. We’ll use them as a starting point.
From consultation to final smile, most cases take about two weeks.
They didn’t have to fly to New York for this appointment. But they did.
One team, every specialty, under one roof: general dentistry, cosmetic, implants, and more.
Comprehensive dental care on Park Avenue, trusted by patients worldwide.
Some things get handed down.
A watch. A style. A last name.
Dr. Jan Linhart handed down all three. Plus a practice on Park Avenue, and a standard he never lowered.
Nepotism? Maybe.
Forty-five years of it working? Undeniable.
Happy Father’s Day from the Linhart family 🧡
A retainer can’t straighten your teeth. It’s right there in the name.
If your teeth have shifted and you’re hoping an old retainer will pull them back into line, it won’t, and forcing an ill-fitting one can do more harm than good.
Straightening is a different job, and a different conversation.
That’s what a consultation with Dr. Heather is for.
Your saliva is doing more than you realize.
It’s a buffer against decay, which is why losing it (to age, medication, autoimmune disease, or radiation) so often leads to cavities.
Dr. Zach on why visible buildup sometimes goes hand in hand with surprisingly healthy teeth.
“It’s a little overprescribed at this point.”
Not what you expect to hear from an orthodontist about braces.
Phase one treatment, the round of early intervention some kids get before all their adult teeth are in, is sometimes exactly what a child needs. Often, it’s not.
The hard part for parents: from the outside, you can’t tell which camp your kid is in.
That’s the whole point of a consultation.
Dr. Heather Kunen will tell you honestly who needs to start now, and who’d do just as well waiting.
Because at Linhart, we don’t over-prescribe.
We tell you what your kid actually needs, even when that’s “let’s wait.”

Your teeth are not the dishes.
Finger pressure, two to three times a day, don’t scrub.
If you’re already a scrubber, an electric toothbrush can actually work against you.
It doubles the pressure and your enamel pays for it.
Electric makes sense for some: older patients, anyone missing spots, anyone who needs the help.
But a manual brush, done right and changed regularly, keeps your teeth just as clean.
No motor required.
And when it’s manual, our Nano-Silver Toothbrush does the work for you.
Ultra-soft bristles that reach everywhere, antibacterial between uses.
