In the first step, a special gel is applied to the surrounding gums for protection. The lips and tongue are covered with a foil. The dental hygienist then applies the bleaching material to the tooth surface and enamel, which has been cleaned days before. The bleaching gel is then activated using a special lamp. This process takes about 15 minutes. The bleaching gel is then removed, a new portion is applied and this process is usually repeated three times. Afterwards, the tooth color is many shades lighter with this method. It’s that easy to achieve your goal. Your reward is a radiant, bright smile with white teeth in less than an hour.
