SmileDirectClub's latest XL water reservoir holds enough water for up to 90 seconds of flossing. Removes 99% of the plaque between teeth and below the gumline—areas that traditional dental floss just can’t reach. Experience the water flosser that’s 50% more effective than regular string floss when it comes to improving the health of your gums. Plus, it’s way easier (and more fun) to use than dental floss or dental picks. 3 pressure modes: soft, normal, and pulse. Easily customize your flosser to find the pressure that’s perfect for you. Soft is recommended for first-time users, and those who have sensitive teeth or gums. Normal is great for experienced users with no sensitivities, and pulse is for those with braces or stubborn areas that need a deeper clean.
