Using a combination of pressured water and bicarbonate it can remove stains left on your teeth by smoking, food, and drink. It is the ideal teeth whitening treatment without direct contact, heat, or noise resulting in the ideal white smile. Airflow polishing is also ideal for anyone who suffers from sensitive teeth, due to the lack of direct contact and the absence of heat and vibration.
