The Kör Whitening Deep Bleaching System begins with just a single visit to take an impression of your teeth. With this impression an accurate model of your teeth are created in order to make the comfortable, form-fitting bleaching tray that you wear for two weeks while you sleep. After a follow up visit the process is complete and your teeth are up to 16 shades whiter. Dr. Hull is proud to be among the thousands of dentists that offer the Kör Whitening Deep Bleaching System to patients of all ages that want whiter teeth with no discomfort. Be sure to ask about the Kör Whitening Deep Bleaching System when you contact our friendly staff.
