Waterpik Aquarius Water Flosser WP-660

Waterpik invented the water flosser, and the Aquarius is its most popular countertop model. A stream of pulsating water removes plaque and food debris from between teeth and below the gumline, which is especially helpful for braces, implants and crowns.

Ten pressure settings run from gentle to deep clean, the reservoir holds enough for 90 seconds, and the seven included tips cover standard flossing, orthodontics, plaque seeking and tongue cleaning. A one-minute timer with 30-second pacer guides each session.

ADA-accepted. Fill the reservoir with warm water and floss once a day.
