There are countless discounts in today's big Prime Day sale, especially when it comes to oral health products (the Philips Sonicare Diamond Clean Toothbrush that Kim Kardashian uses for super-white teeth and the best-selling Oral-B Pro 5000 Electric Toothbrush are both majorly discounted right now, for example). But there's another deal we're especially excited about: The best-selling, customer-loved Waterpik Water Flosser Aquarius is a whopping 50% off today, thanks to Amazon Prime day. But here's the catch—we're approaching the final hours of Prime Day, so if you want to score this must-have oral care gadget for just $40 (yes, really) instead of its regular $80 price, you'll have to do it right now before the mega-shopping event ends tonight

If you want super-clean, healthy gums, this handy gadget is for you. Unlike dental floss, the Waterpik literally repels food and bacteria from the crevices of your teeth using water pressure. "It's a handheld device that uses a small motor to send pressurized water out of a tip," Jon Marashi, DDS, a cosmetic dentist based in Los Angeles, told Health in a 2018 interview. "The tip is placed near the gum line in the mouth, and the water pressure removes plaque buildup along the gum line and in between teeth."

It's a smart purchase for anyone, but because the water flossing technology is able to reach deeper into the crevices between teeth (and even below the gum line), the Waterpik is particularly useful for those who have braces, implants, crowns, or other dental work that makes traditional flossing difficult, as well as those with gingivitis.

The Aquarius model that's on sale for half off today boasts 10 different pressure settings, 90 seconds of water capacity, a seal of acceptance from the American Dental Association (ADA), and—impressively—over 12,000 highly-positive reviews from customers. "I absolutely love this product," raves one reviewer, noting that the Waterpik "cleans and gets all the cracks and crevices." Another called it "the absolute best water cleaning device for teeth."

Dr. Marashi told Health that he often recommends this product to his patients. "It's easier than traditional flossing and can get access to hard-to-reach areas with greater ease," he said. One caveat: Dr. Marashi stresses that the Waterpik should be a supplement to regular floss, not a replacement. "In combination, my patients have much healthier gums as a result."

If you've been wanting to try this water flosser for yourself, now is the absolute best time to buy: The Waterpik Aquarius is only $40 today on Amazon, meaning you'll save 50% on the device. But if you're interested in the deal, don't wait, because the sale only lasts for a few more hours until Amazon Prime Day officially ends tonight—and we don't know if this popular water flosser will ever be on sale for a price this low again. Trust us, your teeth (and gums) will thank you.
