Teeth Whitening in New York City
Lift deep stains and brighten your smile several shades in a single visit with fast, safe professional whitening.
Professional Whitening That Brightens Your Smile in Just One Visit
Stains, yellowing, or dullness can affect even the healthiest teeth, but you don’t have to live with a smile that doesn’t reflect your confidence. At Teeth By Keith, we offer professional teeth whitening in NYC using Wicked White®, a powerful yet gentle in-office treatment that delivers noticeable results in a single visit.
Whether you're prepping for a special event or just want to refresh your look, Dr. Keith R. Marshall, DDS, brings over 40 years of experience and a commitment to conservative, esthetic care to every whitening procedure.
Why Choose Professional Whitening?
Unlike drugstore whitening strips or charcoal pastes, professional teeth whitening is safe, fast, and effective. At our East 32nd Street office, we use Wicked White®, a clinically tested system that:
- Brightens your teeth by several shades in one visit
- Minimizes tooth sensitivity
- It is safe for the enamel and gum tissue
- Requires no trays or at-home upkeep
- Offers longer-lasting results than OTC products
This system has become one of Dr. Keith’s preferred esthetic treatments, especially when paired with smile makeovers or one-visit porcelain crowns and veneers.
What Causes Tooth Staining?
Even with good oral hygiene, your teeth can become discolored due to:
- Coffee, tea, red wine, and soda
- Tobacco use
- Age-related enamel thinning
- Certain medications
- Dark-colored foods like berries and tomato sauce
If you’ve noticed your smile looking dull or yellow, you’re not alone — and professional whitening is one of the easiest ways to boost your confidence.
Our In-Office Whitening Process
1. Shade Assessment
We’ll examine your teeth and select a realistic, natural whitening goal based on your enamel and baseline shade.
2. Gum Protection
A protective gel or shield is applied to prevent irritation and isolate your teeth during the process.
3. Whitening Application
The Wicked White® formula is applied to your teeth and activated using a specialized LED light system.
4. Final Polish
After your treatment, we’ll evaluate your results and provide tips to help you maintain your new bright smile.

Is Whitening Right for You?
Teeth whitening is ideal for patients who:

Frequently Asked Questions
What is the best treatment to whiten teeth?
In-office whitening with a dentist, like our Wicked White® system, is the most effective, safest, and fastest method to whiten teeth several shades in one visit.
Can yellow teeth be white again?
Yes. Most yellow staining responds well to professional whitening. For deeper discoloration, Dr. Keith may recommend porcelain veneers for more dramatic results.
