Many have experienced pain during teeth whitening. Maybe you’ve experienced it yourself. After several years of research, development and clinical testing, the inventor of the KöR Whitening Deep Bleaching System introduced a whitening gel that, in most cases, produces low to no sensitivity. As a result, most patients have no discomfort from whitening when using this technique. Testing has shown that patients who do feel some sensitivity using the KöR Whitening Deep Bleaching System typically feel no more than 10% of the sensitivity they’d feel from other whitening gels.← Is there pain or discomfort with the KöR Whitening Deep Bleaching™ System?
