Flossing helps clear away the plaque that builds up between your teeth and can help prevent common oral health issues like cavities, gingivitis, and gum disease. However, dealing with string floss can feel like a chore. Fortunately, cordless flossers can be a great alternative, as these devices use pressurized water to remove unwanted build-up. Research has shown it can be more effective than string floss for improving dental hygiene, and right now, thanks to this Waterpik sale happening on Amazon, you can get some of the most popular models on the market for stellar discounts.

This fan-favorite Waterpik Nano Plus flosser has nearly 4000 reviews on the site and a 4.4-star rating. It usually retails for $60, but you can get it on sale for $48, so you'll save about 20 percent. Not only that, but you can grab the brand's cordless Advanced model for $80 in white, blue, and black, which is $20 off the regular price.

Both the Nano Plus and Advanced models have earned a seal of approval from the American Dental Association (ADA), but the two units differ in more ways than one. The Nano Plus is 50 percent smaller than others offered by the brand, making it a good choice for those with limited bathroom space or who want to take a flosser along with them when they travel. It also offers five settings and can deliver 1400 water pulses per minute; the tank can also hold up to 15 ounces of water. "I have a very limited space on my bathroom sink and this fits perfectly, and it has the same power as the [full-size] model," one reviewer noted.

Meanwhile, the Advanced model has a 4.5-star rating on Amazon from more than 18,000 reviewers and can help remove up to 99.9 percent of plaque in one minute. It comes with multiple different tips, which can be great if you have braces or want to remove extra build-up. It also offers three built-in, pulsating pressure modes, so you can find the right one that'll work for your teeth and gums. "I am not a faithful flosser; when I did floss, my gums would ache," one shopper wrote. "... This cordless version is perfect for me. I am flossing like never before. My mouth feels 'fresh from a dental-cleaning visit' clean[,] and no aching gums afterward."

You can make your next trip to the dentist easier and get a brighter smile with either the Nano Plus or Advanced water flossers, so be sure to check them out now while they're on sale.
