Prophylaxis powder for supragingival prophylaxis treatments for use with the Air-N-Go unit, designed specifically for delicate tissue. The fine balance between flavour and sodium saccharin concentration removes any unpleasant salty taste and leaves the patient's mouth feeling fresh. Anticlogging and controlled hydrophobic properties of these powders, based on sodium bicarbonate, give a dual-action effect. Microparticles shrink when in contact with water, improving polishing effect. The powder then dissolves gently, avoiding trauma to the delicate tissues and preventing the risk of clogging the Air-N-Go unit.
