Airflow is the simplest method for getting rid of the discolouring on the surface of your teeth. But remember that it cannot get out the discolouring in the depth of the enamel. To ensure the result of the bleaching we recommend the Airflow treatment twice a year. Airflow blast salt with high water pressure on your teeth. To obtain a long lasting the result of the bleaching treatment it is important to clean your teeth thoroughly and avoid food and drink that stains your teeth i.e. coffee, tea, red wine and tobacco.
