We all know that brushing and flossing our teeth regularly is imperative to maintaining our dental health. However, investing in a good water flosser could be even more effective at eliminating plaque and buildup that's hard to reach with regular floss. That said, water flossers aren't always affordable. Luckily, one of our favorites, the Waterpik Aquarius Water Flosser, is on sale right now for one of the lowest prices we've ever seen at Amazon.

- 10 pressure settings
What we don’t like

Waterpik is the first water flosser brand to receive the American Dental Association (ADA) Seal of Acceptance and has been the number one dentist-recommended brand for years. Our editors on the Reviews Team also tested out Waterpik's Electric Toothbrush & Water Flosser Combo for themselves and were impressed with the noticeable results it delivered. Check out our full review to learn more.
The Aquarius Water Flosser packs everything we love about other Waterpiks we've tried. It has 10 pressure settings to clean your teeth effectively. Seven tips are included, all of which can rotate 360 degrees to clean hard-to-reach spots. The 22-ounce water reservoir is removable and dishwasher safe for easy cleaning and holds enough water to run the flosser for 90 seconds uninterrupted. Plus, the flosser has a built-in timer that pulses to allow you to keep track of your flossing time.
With nearly 115,000 five-star ratings on Amazon, it's clear that shoppers love this water flosser as much as we do. "The Waterpik Aquarius Water Flosser has completely elevated my oral hygiene routine. It's easy to use, powerful, and leaves my mouth feeling cleaner than regular floss ever has. The 10 pressure settings are great—I started low and gradually increased to find the level that's best for me," said one reviewer. "I love that it has a built-in timer to guide you through a full cleaning cycle, and the water reservoir is large enough that I don't need to refill it mid-use."
Many shoppers said they'd never go back to just manual flossing after buying a Waterpik. "Simply put, this is the best investment in dental hygiene I've ever made. I'll never be without one again," said another reviewer. "The larger water reservoir means I can take my time. The way the basic tips are bent makes it very easy to direct the water carefully."
With the current discount on Amazon, you can get the Waterpik Aquarius Water Flosser for 40% off the original price. Add it to your cart now for just $60 while the deal lasts.
