A Sampling of KöR Whitening Case Studies.

Like most dental offices, we (and our patients) were entirely frustrated with the poor, short-lasting results from previous whitening systems. Since switching over to KöR, those problems are a thing of the past.



Dr. G. Brooks Haney. Richardson, Texas

I am so happy I’ve found KöR Whitening Deep Bleaching for my office. I am seeing great results and the patients are thrilled! I was very hesitant about whitening the first case below, which is a dark tetracycline stained case.



Alina Muntean, DDS. Surfside Beach, South Carolina

We have found KöR Whitening Deep Bleaching to be the one whitening system we can always count on to impress our patients, every time.



Dr. George Marquis. Fulton, Mississippi

I completed my first KöR Whitening case today, and was very pleased with my result and thought I’d share it with you. My patient said she’d always had dark teeth. She recalled having many antibiotics as a child, and obviously tetracycline was one of them. As you can see, her teeth did have the classic tetracycline look, and there is no doubt that she is a “tetracycline stain” patient.



Mark Nielsen. DDS. Elkhorn, NE

As you know, I’ve been following your KöR Whitening System, and hearing amazing things about it now for the last few years. A little more than a year ago I decided to bring your system to my cosmetically oriented dental practice in the United Kingdom.
The results we’ve seen have simply blown me, my staff, and our patients away! As I said to you in a recent email, “YOU, Sir, are a frickin GENIUS!!!!!!”



Dr Pav Khaira. South Yorkshire, United Kingdom

These are the photos for my first KöR Whitening Deep Bleaching case. We are blown away with the results! I can’t believe how well this worked! I know you say not to do a tetracycline case as your first one, but this patient was desperate to try something instead of having his regular dentist do ear to ear veneers. Lately I have been completely jaded by some of the technology and products out there and how they do not actually have any therapeutic value or are based just on manufacturer claims. But I’ll spread the word, because this product is awesome.



Natasha Lee, D.D.S. San Francisco, CA

I am so happy to show you the following case. One of, if not THE most heart-warming case I’ve ever treated of any sort. This is what being a dentist is all about!


I treated a female patient with KöR Whitening Deep Bleaching, and as always, she had a fantastic result, and was absolutely elated.


Leonard Tau, DMD. Philadelphia, PA

Though KöR Whitening works wonders for tetracycline cases, it is really intended to use on all bleaching cases. I’d like to tell you about the most emotional case I’ve ever treated in my practice. This case had a huge emotional impact on the patient and his wife. My staff and I will always remember what happened.



Walter Mick, DDS. Reynoldsburg, Ohio

Several months ago, a patient brought in her daughter’s wedding pictures and commented how she never smiled in photographs because she was embarrassed. I told her about the KöR Whitening Deep Bleaching™ System, and she agreed to give it a try.



Dave Woltkamp, DDS. Overland Park, Kansas

I was disgusted with the unpredictability and pain of bleaching. I’d heard rave reviews about Rod’s KöR Whitening from many friends and other sources, but I was still a little skittish and skeptical. So I did my first case on a friend of a staff member, free of charge. WOW!! The results were absolutely unbelievable. Almost no sensitivity, and the patient is ecstatic.



Brian Weibling, DDS. Canfield, Ohio

Dr. Kurthy hit a home run! The whitening gel refrigeration, the helpful manuals. . . all amazing. My staff used to be so frustrated with sensitivity and inconsistent bleaching results. Then we tried the KöR Whitening Deep Bleaching™ System and haven’t looked back. One member of my staff even tried it on her mottled teeth. She said that within two weeks of completing KöR Whitening, 40 people must have commented on her improved, beautiful smile!



John Cloud, DDS. Canfield, Ohio

Dr. Rod Kurthy’s KöR Whitening system has helped us achieve our goals of patient satisfaction and practice profitability. We’ve had fantastic results even in patients with severe tetracycline staining! We have also never had a patient experience sensitivity with this system.



Victor Burdick, DDS. Littleton, Colorado

I’d just opened my new scratch practice, and in walked your typical bleaching nightmare: Redhead. Fair complexion. Freckles. And your typical translucent, redhead-type bleaching-resistant teeth. I used the KöR Whitening Deep Bleaching™ System and she said that for the first time ever, she loves smiling.



Seth Gibree, DMD. Cumming, Georgia

In walked the worst case I’d ever tried to bleach. He was too embarrassed to smile and had been since childhood. The KöR Whitening Deep Bleaching™ System changed all that. This is what being a dentist is all about.



Gary Glick, DDS. West Milford, New Jersey

Before KöR Whitening, patients experienced one teeth whitening disappointment after another, which became increasingly frustrating to them, to myself and to my entire staff. After trying the KöR Whitening Deep Bleaching™ System on myself, I knew I had found my secret weapon. My patients and staff are “wowed” every single time.



Yvonne Wong, DDS. Sunnyvale, California

My staff has been completely energized using the KöR Whitening Deep Bleaching™ System on patients, because it changes their lives for the better, forever. In particular, I recall one lady who had always had dark teeth and wanted to attend her 30th high school reunion, but was too embarrassed. We used KöR Whitening and got her to an amazing shade 030. She literally cried tears of joy.



Kevin Potocsky, DDS. Allen Park, Michigan

My patients have gone from having their self-esteem suffer to smiling constantly thanks to the KöR Whitening Deep Bleaching™ System. For the first time in some patients’ lives, they are smiling now. 100% confidence for them and for me!



Stephen Glass, DDS. Spring, Texas

A 61 year old who achieved a shade 020 and a 46 year old who went from a C2 to an 010 with the KöR Whitening Deep Bleaching™ System. My patients have had amazing results. This is the last whitening system you’ll ever want to use!



Ron Evans, DDS. Rockwall, Texas

My 65-year-old practice partner, also a dentist (and an avid coffee drinker) decided to use KöR Whitening after not having much success with other methods. The results were “wow white” and we even had to change the yellow composite on mesial #7 because it was now so noticeable. My patients also love the results they get with the KöR Whitening Deep Bleaching™ System.



Alan Rosen, DDS. Springfield, Missouri
