The KOR Whitening System is one of the newer whitening kits on the market. Our patients have provided a great deal of positive feedback, are happy with the results, and love that the product does not cause sensitivity. Referred to as the “Cadillac of whitening” the KOR System is the first bleaching product to be refrigerated from the point of manufacture until being applied to patient’s teeth. Studies show that these low temperatures maintain its whitening power. KOR has proven to be highly effective in comfortably producing a natural-looking whiter smile.
