Unlike traditional dental floss, the EW-DJ10-A Panasonic Portable Water Flosser creates rapid, targeted jets of water to comfortably and thoroughly help remove harmful food particles, plaque and bacteria from between teeth and gums. Best of all, this dental water flosser has a smart, collapsible design to fit into tight drawer or cabinet spaces, for power flosser storage at home, and in bags and luggage for flosser use while traveling or on-the-go. 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 portable water flosser pulses also reach just below the gum line to remove trapped food particles, and help stimulate the gums keep them strong and resilient. To help maintain healthier gums, the cordless water flosser pulse rate can easily be set to two different power flosser speeds; a high-speed pulse for normal, everyday cleaning, and a gentler, lower-speed pulse for children and those with sensitive gums. Either dental water flosser speed provides safe, complete cleaning for those with braces, crowns, veneers, bridges and implants. And an easy-fill 5.5-ounce water reservoir in this portable water flosser lets you floss longer between fills. Cleaning and maintenance for the Panasonic Water Flosser EW-DJ10-A is simple. All flosser parts are 100% waterproof, and each can be washed and rinsed thoroughly under the faucet, and dried with a clean, soft cloth.
