KöR™ Whitening – The Next Evolution in Teeth Whitening Severe staining, such as that caused by the antibiotic tetracycline, can defeat even the best professional whitening treatments. Which is why we're proud to offer a teeth whitening procedure called KöR Whitening. With KöR Whitening, even these severely stained teeth can become a dazzling white, with no sensitivity! If you've ever been let down by the results from other methods, you will be astounded by this technique. If your teeth are only moderately stained, you can choose the custom whitening trays we create in our own lab. After the initial visit, you will be given supplies and instructions to complete this safe and effective procedure at home. Results become visible within 1 - 14 days.
