The Waterpik Aquarius is 50% off during Prime Big Deal Days

Your smile is the focal point of your face, but how white or straight your teeth are, unfortunately, doesn't define your overall oral health. Many adults will admit they don't floss regularly, even though we all know that a lack of it can lead to more serious problems like gingivitis, the earliest stage of gum disease.

If you don't want to get yelled at during your next dentist appointment, one of the easiest ways to floss is with a water flosser, and our favorite one is 50% off during Amazon's Big Deal Days.

A professional-grade water flosser at a price you won't bare your teeth at

It's easy to tuck a roll of floss into a cabinet and forget about it; the Waterpik Aquarius is not so easily ignored. Powered by a simple cord and made to sit on your counter, the Aquarius has a large, 22-ounce reservoir that provides 90 seconds of continuous flossing, an ample amount for a full-mouth clean. You don't need to refill the reservoir multiple times like with other smaller units.

The Warerpik Aquarius offers 10 settings and includes 7 different tips, ranging from daily use to those specifically designed for orthodontic brackets, bridges, or gentle delivery. This device is also approved by the American Dental Association, backed by a 3-year warranty, and the reservoir is even dishwasher-safe. It's a simple daily way to improve your smile and your oral health at a steal of a price.
