Air-flow is ultrasonic cleaning of dental plaque, which removes deposits in hard to reach places, including in the gingival pocket depth up to 10 mm, with a solution that consists of water, air and soda, and is fed through a special nozzle. As for polishing the teeth, it is special rotating brushes with the use of so-called polishing pastes. As a result the teeth become lighter. But unfortunately this effect can't stay forever. For many people who are doing this procedure at first, as a rule, is a pleasant surprise that they have such white teeth. This cleaning is done once in six months (six months) as a prevention.
