Unlike traditional dental floss, the Panasonic Portable Dental Water Flosser and Oral Irrigator EW-DJ10-A520 creates rapid, targeted jets of water to comfortably and thoroughly help remove food particles, plaque and bacteria from between teeth and gums. This dental water flosser features a smart, collapsible design to fit into tight drawer or cabinet spaces for storage at home and in bags and luggage for use while traveling. By flossing at 1,400 water pulses per minute (in normal mode), this power flosser penetrates deep between teeth to wash away the debris, plaque and bacteria everyday floss can't always reach. These cleansing pulses also reach just below the gum line to remove trapped food particles and help stimulate the gums.
