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.
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.
Some appointments feel like a chore. This one feels like arriving somewhere.
Steps from Grand Central. Eleven floors above Park Avenue. A practice where the care starts before anyone picks up an instrument.

“I’ve had to retreat patients. I’ve had to fix the messes.”
Dr. Heather Kunen has seen what happens when orthodontic treatment isn’t handled by a specialist.
A lopsided bite. Unfinished alignment. Work that just wasn’t done right.
There’s a reason orthodontics is a specialty.

The consequences are known. And unknown. We’re still learning what vaping and nicotine pouches will do long-term.
But the lesions are already here.
Every generation introduces something new to the mouth. The timeline:
Cigarettes → oral cancer link established
Dipping/chewing tobacco → gum damage, lesions, cancer
E-cigarettes → “safer alternative” (still causes oral tissue damage)
Zyn pouches → “tobacco-free” (still damaging gums and tissue)
Marijuana → smoke irritation, dry mouth, lesion risk rising
Every generation, we see the same pattern: lesions, tissue changes, precancerous conditions, increased cancer risk.

Dipping. Zyn. Vaping. Cigarettes. Cigars. Marijuana.
All of these products damage oral tissue. Some in ways we understand. Some in ways we’re still discovering.
Nicotine restricts blood flow to gums. Smoke irritates tissue. Constant contact (pouches, dip) causes white patches and precancerous lesions.
The long-term effects of vaping and nicotine pouches? We don’t know yet. We don’t have 20-year studies.
But we’re already seeing the damage in younger patients.
“It’s tobacco-free, so it’s safer.”
“It’s vaping, not smoking.”
“It’s just a pouch.”
Different marketing. Same outcome: oral lesions are rising.
Dipping, Zyn pouches, e-cigarettes, cigarettes, cigars, marijuana… all of them damage oral tissue.
We know nicotine restricts blood flow. We know smoke irritates tissue. We know constant contact causes lesions.
What we don’t know: the full long-term effects of vaping and nicotine pouches. We’re introducing these products faster than we can study them.
But the damage is already showing up. White patches. Tissue changes. Precancerous lesions. In patients younger than we used to see.
“Safer” doesn’t mean safe. Your mouth is showing us that.
I can tell when a patient uses ZYN.
The gum tissue tells me before they do.
Any repeated rubbing against the gum — over time — can cause oral cancer. Doesn’t matter if the packet has tobacco or not.
“They’re safer than smoking, right?”
For your lungs, maybe. For your gums? No.
The nicotine restricts blood flow to your gums. The constant contact irritates the tissue. Over time, you get recession, lesions, and increased risk of oral cancer.
Made to your specific bite to protect against grinding and reduce jaw strain.
If your stress is showing in your teeth, a night guard isn’t optional. Grinding wears down enamel you can’t get back.
