KöR teeth whitening is a highly advanced, innovative teeth whitening brand. Continuously refrigerated whitening gel and special KöR-Seal trays are used to keep deep bleaching treatments incredibly effective. Warmer temperatures and saliva cause teeth whitening gel to break down faster, resulting in less effective treatments. With KöR deep bleaching, patients can achieve much whiter teeth in a shorter time frame. Patients also tend to experience less tooth sensitivity, which results in more comfortable treatments.
