We Can’t Believe This Sensitive Gum Product Outsold So Many Fancy Devices This Prime Day

"I can literally feel the difference in how clean my teeth feel. It truly feels like I had just gone to the dentist and they deep cleaned my teeth themselves."
The Dr. Plotkas Mouthwatchers flossing toothbrushes from Amazon.

On Prime Day, our editors have access to viewing Amazon’s top-selling products — so we know all the dirty secrets about what’s in your cart. And here’s a shocking one for you: This little oral-care gadget beat out of a lot of powerhouse products on Amazon’s list of all-stars.

“I can’t shut up about this toothbrush,” writes a reviewer named Susanna, who took the words out of my mouth.

The toothbrush in question? The Mouthwatchers flossing brush. Reviewers can’t believe they’re waxing eloquent about a manual toothbrush, and I can’t either. But this isn’t your run-of-the-mill dental product — and it’s on major sale right now for October Prime Day.

Designed by Boston-based dentist Dr. Ronald Plotka, the brush’s genius lies in its top layer of extra-thin bristles, 10 times thinner than typical bristles. This feature helps clean deeper, yet gently, into grooves and gums.

The result is a super-clean, “like leaving the dentist clean” feeling after every go-round — so much so that reviewers, to their surprise, are getting excited about brushing their teeth and describing the toothbrush as “magic.” Same here. I’d been eying this brush for months, putting off trying it due to my intense dislike of spending money. Once I finally did, I wished I’d done so sooner.

The Dr. Plotka's Mouthwatchers toothbrushes have a super-thin top layer of bristles that emulate flossing.

Rarely does an item elicit an actual wow from me. Yet, as a reviewer named Christie writes, “Here we are.”

Within about a week of switching from a regular brush to this one, my previously coffee-stained teeth looked markedly whiter, my plaque was less visible and my gums looked healthier.

My mouth also feels remarkably cleaner, a result that reviewers echo. I can’t help but feel that this model is toothbrushing the way it should be.

One reviewer named Cole sums it up nicely: “Ever since I started using Dr. Plotkas I simply cannot tolerate another brand of toothbrush ... I recently traveled and did not switch out my travel brush with this product. I felt like I was brushing my teeth with rubber spikes. It was the longest week ever.”

Reviewers’ families are a little taken aback by this fervor (as may be my editor, whom I’ve pestered about this life-changing toothbrush for longer than I’m proud of). But no matter: It’s only a matter of time before everyone else becomes stalwarts, too, reviewers say. “I have converted everyone in my family,” writes Cole, and another person says they plan to gift the brushes to family members “so they’ll stop looking at me like I’m a little bit off for talking about my toothbrush.”

It’s a clear new staple for me, and more than worth the extra few dollars.

Grab a two-pack of the flossing toothbrushes to try for yourself. Still thinking? More reviews below:

“I’ve tried various types of toothbrushes over the years, both electric and manual and this brush is by far the best! It does feel bigger in my mouth than most others, BUTTT it cleans SOOO well! Dare I say better than any electric brush I’ve ever tried. My teeth feel like I’ve just had a professional cleaning!” — amanda.park

“This cleans so well yet is gentle enough for my older lightly receding gums. The bristles are very fine and cleans between teeth a bit. Don’t know how deep so I’m continuing to use my floss. It’s got a good bigger rubberized grip which makes this comfortable to hold. Does not slip. My gums love the brush too! I don’t travel much but if needed can slip it into a plastic travel case. I’ll be stocking up on these!” — Babs

“I never thought I would write a review for a toothbrush, but this is the best toothbrush I have ever bought. It feels sturdy and yet so soft and makes my teeth feel so clean. I will definitely buy more!” — Katie McPheters
