My name is Yvonne Wong. My husband and I are dentists in Sunnyvale, California. Before KöR^® Whitening, we had nothing but disappointment after disappointment. Patients often didn’t notice any whitening; and, if they did, they still weren’t happy. I was disgusted and hardly ever mentioned bleaching to patients.

I decided to get Dr. Kurthy’s KöR^® Whitening training manual, and tried it on myself. My teeth got incredibly white (just look at my picture now!), and my staff was simply amazed. Then they all wanted KöR^® Whitening. I had found my secret weapon.

My confidence shot up and I fell in love with dentistry again. I can feel a change in the way I talk to patients now. If you haven’t tried KöR^® Whitening yet, your jaws will drop to the floor when you see the results. Every time a patient sees their teeth when we finish a case, they can’t believe the results, and my entire staff is “wowed” every time. It’s contagious.

I am amazed at how much bleaching I do now. Most referrals come to me because of KöR^® Whitening. Their friends get KöR^® Whitening, and then they want the same thing.

I recently had a patient with very, very dark tetracycline stained teeth. She said that everyone used to ask her if she was a smoker. We didn’t have a shade guide in the office that even came close to her dark teeth, but when we were done with KöR^® Whitening, she was much lighter than a B-1. She said this was one of the most important things that had ever happened to her.

Thank you so much for that, Dr. Kurthy. I love being a dentist again.
