The Rio Compact Water Flosser & Oral Irrigator is a super compact water flosser taking up virtually no space when travelling. Now it is easy to continue flossing wherever life takes you. Water flossing provides cleaning deep between teeth and below the gum line for better gum and oral health. Water flossing is gentle on the teeth and gums, removing more plaque and debris from between the teeth than manual brushing and penetrating deeper than flossing alone.
