KöR® Whitening

You deserve a bright, white smile, regardless of your age. KöR® Whitening Deep Bleaching System can restore the beauty of your smile in just two weeks, with results that can last a lifetime.

Over many years, every day stains can work their way deep into the enamel of your teeth. KöR Whitening Deep Bleaching System provides a thorough removal of these stains from your enamel, rejuvenating your teeth with amazing whiteness. This happens by restoring your teeth’s ability to absorb oxygen. Oxygen from the KöR whitening gel is absorbed deeply into the tooth, dissolving stains at the molecular level. Discover the benefits of KöR Whitening!

  • KöR Whitening is the only recognized system in the world that will whiten tetracycline (dark) stained teeth, previously thought to be impossible.
  • With easy periodic at-home maintenance, your teeth can stay white even while you continue to drink red wine, tea, and coffee.
  • During the whitening process, nearly all patients experience low to no tooth sensitivity.
  • Teeth whitening has been clinically proven to be safe for teeth and gums, so there is no need to worry about harming your smile.

The KöR Whitening Process

During your visit to our office, we will take an impression of your teeth and create a set of thin, form-fitting, ultra-comfortable KöR Whitening Trays. You only need to wear your trays, filled with KöR patented bleaching gel, while you sleep, so they won’t interfere with your lifestyle. With a final in-office whitening session, your treatment will be complete and your smile will be bright.

What Is KöR® Whitening?

At Northern Valley Aesthetic Dentistry, we evaluate your smile, discuss your whitening goals, and create a plan based on your specific needs.

Why Choose Us for KöR® Whitening


A successful whitening experience starts with choosing the right treatment for your smile. At Northern Valley Aesthetic Dentistry, we focus on personalized cosmetic care rather than a one-size-fits-all approach.

Before and After Smile Whitening

Every patient’s teeth respond differently to whitening. We evaluate your current tooth shade, staining concerns, and smile goals to recommend an approach designed around your needs.

Your whitening treatment is planned with careful consideration of your oral health, helping ensure the process is appropriate for your smile before beginning treatment.

Our goal is not an artificial-looking smile. We focus on creating a brighter appearance that complements your natural teeth and overall facial features.

We consider factors such as tooth sensitivity and your dental history when planning your whitening treatment to create a more comfortable experience.

As part of our cosmetic dentistry services in Closter, NJ, we combine detailed planning with modern whitening techniques to help patients achieve their desired smile improvements.

The Benefits of KöR® Whitening


KöR® Whitening provides a professional approach for patients looking to improve tooth discoloration and achieve a brighter smile. For discoloration that whitening cannot effectively address, veneers may be another option to consider.

Address Stubborn Tooth Stains

KöR® Whitening may help improve the appearance of deeper discoloration that can be difficult to address with regular whitening products.

Enjoy Professional Whitening Care

With dentist-supervised treatment, your whitening plan is customized based on your smile, dental health, and whitening goals.

Achieve a More Confident Smile

A brighter smile can help patients feel more comfortable during everyday conversations, photographs, and special moments.

KöR® Whitening Treatment Process

Our KöR® Whitening process is designed around your smile goals, dental health, and desired level of brightness.

We begin by discussing your whitening goals, concerns about tooth discoloration, and the type of results you would like to achieve.

Dr. Avianto examines your teeth and overall oral health to determine whether KöR® Whitening is a suitable option for your smile.

Based on your evaluation, we create a personalized whitening approach designed around your needs and comfort.

Once your personalized plan is ready, you can begin your KöR® Whitening treatment with dentist-guided instructions and customized whitening trays. Our team provides guidance throughout the process to help you achieve safe, effective, and natural-looking results.
