Save big on this dentist-recommended Waterpik flosser during Amazon's Big Spring Sale

'My teeth have never felt cleaner': Ditch the awkward string and blast away plaque and bacteria with good ol' H2O.

While brushing and flossing might not be your favorite part of the day, both are critical for a healthy smile. If you've been looking to step up your oral-hygiene routine, today's your lucky day: Waterpik's Cordless Advanced Water Flosser is almost 25% off during Amazon's Big Spring Sale. The battery-powered tool expertly flosses your teeth with water, no yucky string required.

This water flosser is powerful, but don't worry — it operates quietly and gently.

Why is this a good deal?

You can bring home the top-rated Waterpik Cordless Advanced Water Flosser now for $76, down from $100. This is one of the lowest prices we've seen on this popular flosser all year, and since it's part of Amazon's Big Spring Sale, we have a feeling these steep savings won't last long.

Why do I need this?

If you've never considered a water flosser, you're missing out. Not only is a water flosser easy to use (simply fill the reservoir with warm water and you're ready to go), but it "removes up to 99.9% of plaque and is up to 50% more effective than dental floss for improving gum health," according to the brand. It's also worth noting that 9 in 10 dental professionals recommend Waterpik.

This water flosser features a ton of thoughtful details that make it stand out from the crowd. It comes with four rotating tips, a shower bag and a tip case. There are three pressure settings, and the dishwasher-safe reservoir holds 7 ounces of water for about 45 seconds of flossing time. It's also easily rechargeable — the charger connects magnetically and fully juices up the flosser in just four hours.

Better yet, everything is travel-friendly. From the compact, cordless design to the convenient travel case, you don't have to sacrifice your oral-hygiene routine on the go.

What reviewers say

Amazon shoppers can't get enough of Waterpik's water flosser: More than 39,000 reviewers have given it a five-star rating. As this reviewer said: "I always thought I brushed and flossed thoroughly until I saw what I had missed! My teeth have never felt cleaner!"

One pleased customer said this flosser "cleans teeth as well as a dental hygienist!" They went on to share: "I've always been careful about flossing, but my gums still got inflamed occasionally from food the floss didn't reach. That has not happened once since I started using the Waterpik. Worth every dime!"

Another happy shopper said this Waterpik is top of the line. "I purchased a less expensive version three-plus years ago. It functioned adequately, but was loud and shrill, with very limited functionality. The 'advanced' version is much quieter, with a deeper, more comfortably pitched sound. It also comes with a magnetic charger, and lights that tell you when the charge is needed, and when it is complete (a huge improvement)."

"The manual informs you that the reservoir holds 45 seconds worth of water," a third fan said. "That doesn't seem like much ... The tradeoff, however, is very positive. This Pik is every bit as powerful as it should be, holds a charge wonderfully, takes up minimal space and, above all, we can toss it in a bag and take a trip."
