With air-flow, we manage to remove stains in the most inaccessible parts of our teeth, such as stains from smoking, coffee, chocolate, tea, red sauces and dental plaque. The dentist uses a special device that shoots the teeth with water and soda, giving them their best natural color. By the end of this treatment, the dentist can do fluorosis using a special gel in the new patients' teeth. The absence of inflammation of the gum and tartar of the teeth is a necessary condition for applying air-flow.
