Just brushing your teeth leaves behind food particles and plaque that can cause bad breath, tooth decay, gum disease and staining. The Waterpik Water Flosser is the easy and most effective way to floss. It provides a unique combination of water pressure and pulsations to clean deep between teeth and below the gumline where traditional brushing and flossing can't reach. You can get healthier gums and brighter teeth in just a minute a day. This bundle features the full size ultra plus water Flosser and the convenient cordless plus that is rechargeable and portable. The water Flosser removes up to 99.9% of plaque from treated areas and is up to 50% more effective than string floss for improving gum health.
