Consistent, Even Results

Unlike over-the-counter products, KöR Whitening provides predictable, uniform results across all your teeth. No blotchy or uneven spots—just a naturally brighter, more radiant smile.

Comfortable Treatment Process

KöR’s advanced whitening formula is specifically designed to minimize sensitivity while delivering powerful results. Whether in-office or at home, patients report little to no discomfort compared to store-bought whitening products.

Longer-Lasting Brightness

With KöR’s continuous refrigeration technology, the whitening gel remains highly potent, delivering results that last significantly longer than traditional methods. Regular touch-ups and good oral hygiene help maintain your brighter smile for years!

Understanding Teeth Stains

Diet

Dark-colored foods and drinks like coffee, tea, and red wine can cause staining over time.

Aging

As you age, the enamel on your teeth naturally thins, revealing the yellow dentin underneath.

Smoking

Tobacco use is a common cause of severe tooth discoloration.

Medications

Certain medications can lead to intrinsic stains that are harder to remove.

Why You Should Whiten Your Smile with Your Dentist

While DIY whitening kits may seem convenient, they often deliver uneven, unpredictable results and can cause increased sensitivity. Whitening with KöR under the care of a dentist ensures:

  • A personalized approach tailored to your level of discoloration.
  • Advanced KöR whitening technology that deeply penetrates enamel for lasting results.
  • Supervised care to minimize sensitivity and protect your teeth and gums.
Developed by internationally renowned cosmetic dentist and teeth whitening expert, Dr. Rod Kurthy, the KöR Whitening System is used by thousands of dentists worldwide and is widely considered tobe the most reliable and effective whitening system ever developed.
The KöR Whitening system has proven to consistently produce whiter, brighter smiles in patients. In fact, the KöR system is so effective, it is the only recognized whitening system that whitens tetracycline-stained(dark) teeth in a short time (previously considered impossible).

And due to its advanced formulation and continuous refrigeration of the whitening gels, there's little to no sensitivity during the whitening process.

The Unique KöR-Seal Trays

One of the keys to the effectiveness of theKöR system is the unique KöR-Seal™ whitening trays used for at-home whitening. These trays are made of thin clear flexible vinyl and are carefully fabricated to fit very precisely to your teeth.

Most patients find these trays extremely comfortable to wear and have no trouble sleeping with them. These unique KöR-Seal whitening trays allow room for whitening gel to be kept in contact with the teeth, and they seal at the gum line so that gel is not diluted, washed away, or inactivated by saliva. This ensures the maximum whitening results.

And the KöR Whitening System is perfect for patients of all ages, including teenagers and baby boomers.

How Does KöR Whitening Work?

The KöR Whitening System is a safe, effective, and convenient cosmetic dentistry procedure that can improve the appearance of teeth to restore self-esteem and self-confidence.

So, if you're too embarrassed to smile, have dark-stained teeth, or just simply want a whiter smile, the KöR Whitening System offers the best in whitening science, and is by far the best whitening system available today.

What to Expect During Your Whitening Treatment

1. Consultation and Assessment

Dr. Mahon will examine your teeth and gums to ensure whitening is right for you. We’ll discuss your goals and recommend the best whitening option for your needs.

2. In-Office Whitening

For patients wanting instant, dramatic results, we offer KöR in-office whitening treatments. The whitening gel is applied to your teeth, breaking down deep stains while maintaining enamel integrity. Many patients see up to 16 shades of improvement in a single visit.

3. Take-Home Whitening Trays

Prefer a more gradual approach? KöR take-home trays allow you to whiten your teeth comfortably at home with professional-strength gel. These trays are custom-made to ensure an even application, and patients often see noticeable results in as little as two weeks.

4. Aftercare and Maintenance

To maintain your whitening results, we provide detailed aftercare instructions, including tips on avoiding stain-causing foods and drinks. Regular dental cleanings will also help keep your smile looking its best.

Is Teeth Whitening Right for Me?

Teeth whitening is a great option for many patients, but it’s not ideal for everyone. You might be a good candidate if:

  • You have yellow, brown, or deep intrinsic stains on your teeth.
  • Your teeth and gums are generally healthy.
  • You’re looking for a quick, non-invasive way to enhance your smile.

If you have crowns, fillings, or veneers on your front teeth, alternative cosmetic options may be better suited for you. Dr. Mahon will discuss the best approach during your consultation.
