If you are considering whitening, KöR whitening targets stubborn stains better than other whitening systems. For the best results, we recommend using KöR whitening at home custom trays for two weeks. These trays are designed to fit precisely on your teeth and prevent saliva from deactivating the bleaching agents. These trays are worn at night for 6-8 hours. Following the at home stage, an in-office stage is performed if color has not been achieved yet. During this appointment, your gums are isolated and a very strong bleaching agent is applied to the enamel of your teeth and allowed to penetrate the stain for 20 mins. This 20 min cycle is repeated  3 times in one in office session.
