Considered the gold standard in water flossers by many, the Waterpik Aquarius is a compact system that helps you stay on top of your oral care much more easily.

Not only has this popular flosser earned the American Dental Association’s seal of acceptance, but it also has over 120,000 5-star ratings on Amazon, and many say it “makes my teeth feel like I just left the dentist every single time.” One happy flosser said that the Aquarius improved their gums so much, their dental hygienist showed off their tests, “like a proud mother showing off her son’s report card.”

If this machine feels vaguely familiar — you’re not imagining things. According to the National Library of Medicine, this tool has been around since the ’60s.

One reviewer says they remember their father’s original Waterpik (the brand was founded in 1962), calling it the “appliance that has stood the test of time,” and a “great old classic” that’s still “essential for dental health.”

Today’s Waterpik Aquarius features enhanced pressure with 10 cleaning settings and a handy built-in pacer that automatically stops at 30 seconds and one minute to help you track your flossing. A 360-degree rotating tip ensures the pressurized water reaches all surfaces of the teeth with a 22-ounce that lasts for over 90 seconds of use, meaning you won’t have to stop to refill it mid-floss. It can also go in the dishwasher on the top rack when it’s time to clean. This option comes with seven tips, so multiple people in your house can use the machine or single users can enjoy various styles.
