Unlike traditional dental floss, the Panasonic Portable Dental Water Flosser and Oral Irrigator EW-DJ10-A 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. 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. An easy-fill 5.5-ounce water reservoir in this portable water flosser lets you floss for up to 40 seconds between fills. Cleaning and maintenance for the Panasonic Water Flosser EW-DJ10-A is simple; All flosser parts are waterproof and each can be washed and rinsed thoroughly under the faucet, and dried with a clean, soft cloth.
