Designed for use with the Panasonic EW-DJ10-W and EW-DJ10-A Water Flossers, the Water Jet Nozzle Replacement (EW0955W) uses a tapered tip to provide a deep clean. The Water Jet Nozzle works with the Panasonic Water Flosser (not included) to provide a powerful, continuous stream of water to clean tooth surface, reach deep between teeth and clean under the gum line in periodontal pockets.
