Professional Teeth Whitening in Maspeth, NY
A bright, confident smile can change the way you feel about yourself—and the way the world sees you. Teeth whitening is one of the most popular cosmetic dental treatments because it is conservative, effective, and can dramatically enhance your appearance in a short amount of time. At Fitzsimons & Hagan Dentistry, we offer professional teeth whitening using the KOR Whitening System, an advanced whitening solution known for maximum results with minimal to no sensitivity.
Unlike over-the-counter whitening products that often lead to uneven results and uncomfortable tooth pain, KOR whitening is designed to safely lift deep stains while protecting your enamel and keeping you comfortable throughout the process. It’s so effective that our entire team uses it on their own smiles—including Dr. Bronwyn Hagan.
What Is Teeth Whitening?
Teeth whitening is a cosmetic dentistry procedure that lightens the color of your natural teeth by removing stains and discoloration from the enamel and dentin. Over time, teeth naturally darken due to aging, lifestyle habits, and everyday wear. Whitening treatments work by breaking down stain molecules so your teeth appear brighter, fresher, and more youthful.
When performed under the supervision of a dentist, whitening is both safe and predictable, delivering results that simply can’t be matched by store-bought products.
Why Teeth Become Discolored
Tooth discoloration is extremely common and happens gradually. Some of the most common causes include:
- Coffee and espresso
- Tea (both black and green)
- Red wine
- Dark-colored sodas
- Dark berries (blueberries, blackberries, cherries)
- Tobacco use or smoking
- Poor oral hygiene
- Natural aging
- Certain medications or medical conditions
Even patients who brush and floss consistently may notice yellowing over time. Teeth whitening targets stains that have accumulated both on the surface of the enamel and deep within the tooth structure.
Professional Teeth Whitening vs. Over-the-Counter Products
Many patients come to us frustrated after trying whitening strips, gels, pens, or trays purchased online or at drugstores. While these products may promise dramatic results, they often fall short—and can even cause harm.
Over-the-counter whitening products:
- Use lower-quality ingredients
- Are not customized to your teeth
- Often cause uneven whitening
- Frequently lead to tooth sensitivity
- Deliver limited or short-lived results
Professional whitening at our office:
- Uses dentist-approved, high-quality materials
- Is customized to your smile
- Produces even, consistent results
- Minimizes sensitivity
- Achieves significantly brighter outcomes
With professional whitening, you’re not guessing—you’re guided by experienced clinicians who prioritize both aesthetics and oral health.
Our Preferred System: KOR Teeth Whitening
At Fitzsimons & Hagan Dentistry, we exclusively use the KOR Whitening System because it consistently delivers outstanding results with little to no sensitivity.
KOR whitening is widely regarded as one of the most effective whitening systems available in dentistry today. It is especially powerful for patients with:
- Deep, stubborn stains
- Yellow or dark teeth
- Past whitening failures
- Sensitivity concerns
The system works by restoring the tooth’s ability to absorb oxygen, which allows stains to be lifted more effectively—without aggressive chemicals or harsh light activation.
Minimal Sensitivity, Maximum Results
One of the biggest concerns patients have about teeth whitening is sensitivity. Many people have tried whitening in the past and experienced sharp “zingers” or lingering discomfort that made them hesitant to try again.
KOR whitening is different. The system is designed to rehydrate the teeth and seal the enamel, dramatically reducing post-whitening sensitivity. In fact, many patients who believed they could never whiten their teeth comfortably are surprised by how gentle KOR feels.
Dr. Hagan’s Personal Experience With KOR Whitening
Dr. Bronwyn Hagan personally uses the KOR whitening system and often shares her experience with patients:
“Being a dentist, I feel it's important to have a bright, white smile. I've used so many teeth whitening systems in the past that gave me terrible sensitivity. Days after stopping treatment, I would still wake up with little zingers in my teeth. However, I have zero sensitivity with KOR whitening, and the best part is that I whiten my teeth while I sleep, and I touch up my results as needed, before holidays and date nights.”
When your dentist chooses a system for her own smile, you can feel confident you’re receiving the best option available.
In-Office Teeth Whitening
In-office teeth whitening is ideal for patients looking for immediate, dramatic results. This option is performed entirely in our office under professional supervision.
Benefits of in-office whitening include:
- Faster results
- Controlled application for safety
- Enhanced whitening power
- Professional monitoring throughout treatment
The severity of your tooth discoloration will determine how many whitening sessions are recommended. Some patients achieve their desired brightness in one visit, while others benefit from a combination approach with take-home whitening.
At-Home Teeth Whitening With KOR
One of the most popular features of the KOR system is its at-home whitening option, which allows you to whiten comfortably while you sleep.
You’ll receive custom-fitted whitening trays designed specifically for your teeth, along with KOR’s professional-grade whitening gel. Because the trays fit precisely, the gel stays where it belongs—reducing irritation and maximizing results.
At-home whitening is ideal for:
- Patients who prefer gradual whitening
- Busy schedules
- Maintaining long-term results
- Touch-ups before special events
Many patients love the flexibility of whitening on their own time while still achieving professional-level results.
Combination Whitening for Best Results
For many patients, the best results come from combining in-office whitening with at-home KOR trays. This approach allows us to jump-start your whitening in the office and then continue refining your shade at home.
This combination method offers:
- Longer-lasting results
- Greater overall brightness
- More control over final shade
- Easy future touch-ups
Who Is a Good Candidate for Teeth Whitening?
Most adults with healthy teeth and gums are excellent candidates for professional whitening. Before beginning treatment, we’ll evaluate your oral health to ensure whitening is safe and appropriate.
You may be a great candidate if you:
- Have yellow or stained teeth
- Want a brighter smile for an event
- Are unhappy with your current tooth color
- Have experienced sensitivity with other systems
Patients with crowns, veneers, or fillings on front teeth may still benefit from whitening, though existing restorations will not change color. We’ll discuss your goals and expectations during your consultation.
How Long Do Teeth Whitening Results Last?
Teeth whitening results vary depending on lifestyle habits and oral hygiene. With proper care, results can last months to years.
To maintain your bright smile, we recommend:
- Regular dental cleanings
- Touch-up whitening as needed

- Avoiding tobacco use
The KOR system makes touch-ups simple, allowing you to refresh your smile before holidays, weddings, or special occasions.

Frequently Asked Questions About Teeth Whitening
Does teeth whitening damage my enamel?
No. When performed professionally and with a dentist-approved system like KOR, teeth whitening does not damage your enamel. KOR whitening is specifically designed to protect and rehydrate the teeth, making it one of the safest whitening systems available. We always evaluate your oral health before whitening to ensure treatment is appropriate.
Will teeth whitening cause sensitivity?
Sensitivity is one of the most common concerns we hear from patients. Traditional whitening systems can cause sharp, lingering sensitivity, but KOR whitening is known for minimal to no sensitivity. Many patients who could not tolerate whitening in the past are able to whiten comfortably with KOR—including Dr. Hagan herself.
How white will my teeth get?
Results vary depending on your starting shade and the cause of discoloration, but professional whitening can often lighten teeth by several shades. Deep stains that did not respond to other systems often respond very well to KOR whitening. During your consultation, we’ll discuss realistic expectations and customize your treatment plan.
How long does teeth whitening last?
With good oral hygiene and lifestyle habits, whitening results can last many months to years. Drinking staining beverages in moderation, avoiding tobacco, and maintaining regular cleanings will help preserve your results. One of the benefits of KOR whitening is the ability to easily perform touch-ups at home when needed.
Can I whiten my teeth if I have sensitive teeth?
Yes—many patients with sensitive teeth are excellent candidates for KOR whitening. The system is designed to reduce sensitivity by sealing the enamel and rehydrating the teeth. If you’ve avoided whitening in the past due to discomfort, this may be the solution you’ve been waiting for.
Will crowns, veneers, or fillings whiten?
No. Teeth whitening only works on natural tooth enamel. Existing crowns, veneers, and fillings will not change color. If you have visible restorations, we’ll discuss how whitening may affect your overall smile and whether additional cosmetic options should be considered.
Is at-home whitening as effective as in-office whitening?
At-home whitening with KOR trays is extremely effective and delivers professional-level results over time. In-office whitening offers faster initial results. Many patients achieve the best outcome by combining both approaches, allowing for maximum brightness and long-term maintenance.
How long does the whitening process take?
In-office whitening is completed in a single visit, while at-home whitening typically takes place over several nights. Your exact timeline depends on the severity of discoloration and your whitening goals. We’ll create a plan that fits your schedule and desired results.
Is teeth whitening safe for everyone?
Most adults with healthy teeth and gums are good candidates for whitening. Patients with untreated cavities, gum disease, or certain dental conditions may need treatment before whitening. We always perform a thorough evaluation to ensure whitening is safe for you.
