The Water Jet is the #1 seller in Japan for one reason. It is the most recommended by dentists for defending against tooth decay. How important is it to clean your teeth deep down? It’s far more important than you may realize. Speak with any dentist today and they’ll all tell you nearly the same thing. Brushing and flossing are simply not enough. No matter how thoroughly you floss you can never reach every nook and cranny of the mouth. Getting below the gum line is more important than ever to defend against the onslaught of periodontal disease. Not only that, but the massaging of your gums is nearly as important as cleaning your teeth. Regularly massaging your gums promotes regular blood flow that is important to the long term health of your teeth. The Water Jet provides a strong pulsating stream of water that flushes away hard to reach food particles while providing deep gum massage. That means you’ll get much needed blood flow to areas often neglected with normal brushing and flossing. Includes 4 separate, color coded nozzles that easily connect to Water Jet holder. Perfect for a family of four. Water tank holds enough water for 1.5 minutes of use and has a water pressure regulating switch. Clean where floss and brushes can’t. With the #1 selling, #1 dentist recommended Water Jet you’ll be on your way to whiter, brighter, healthier teeth and gums.
