About this item

  • SUPERSIZED BRUSH HEAD FOR SUPERIOR CLEANING - The wide oval brush head coupled with a flexible neck helps target those tricky to reach areas more easily, massaging the whole mouth as it goes for an all over tingly clean.
  • 3X LONGER LASTING BRISTLES - Made from vegetable based nylon bristles (which in case you're wondering are BPA-free, ADA accepted) the Flex Brush lasts 3X longer than other run of the mill toothbrushes.
  • FLEX NECK TECHNOLOGY - The Flex Brush’s wide soft head stems from an angled neck reduces pressure on gums and teeth. Especially if you're a hard brusher. Bristles are softer and more uniquely aligned providing even pressure that reduces chronic issues.
  • AWARD WINNING "EASY-GRIP" DESIGN - The RADIUS Flex Brush user friendly handle complies with recommended 45 degree brush to tooth angle and the smart Thumb and Palm design makes it much easier to grip and control.
  • ADA ACCEPTED - Accepted by the American Dental Association. All RADIUS Toothbrushes are a must have for clean teeth & gums.

Finally decent toothbrushes!!

VanillaPepperApril 22, 2025

I don’t know what’s happened to toothbrushes lately, but it seems like every new one on the market either feels cheap, has bristles that are way too harsh, or just doesn’t clean well. I’ve tried so many brands—everything from drugstore basics to overpriced “designer” brushes—and honestly, they all fell short. That is, until I found the RADIUS Big Brush BPA Free & ADA Accepted toothbrush. Total game-changer. The first thing you notice is the brush head—it’s big, like the name says, but in the best way possible. It covers more surface area, which means fewer strokes to get a thorough clean. And the bristles? Absolute perfection. Soft enough that they don’t shred your gums but firm enough to get rid of plaque. I have sensitive gums, and this is the first brush that leaves my mouth feeling fresh and clean without irritation. What I also love is that it’s BPA-free and eco-friendly. The handle is comfortable to hold and gives you great control, and knowing it’s made from sustainable materials is just the cherry on top. Plus, it’s ADA accepted, which reassures me that it’s not just some random product—it’s legit. I’ve tossed all my other brushes at this point. This is the only toothbrush I trust now. Seriously, if you’re tired of flimsy brushes that don’t get the job done (or worse, hurt your gums), do yourself a favor and try this one. It’s worth every penny. And hey, after all the toothbrushes and everything else I’ve ordered on Amazon, I’m still wondering how I’m not a Vine reviewer yet! Read more

It's a very big mouthful

NeilAugust 25, 2023

8/2023 I wanted a bigger toothbrush head, maybe 3 times the usual size. This is more like 6 times the usual size. It's a very big mouthful. A much bigger head means that to press the bristles into the teeth with the same amount of force as you did with the traditional, little toothbrush, you have to push a little harder with your hand. Theoretically, the chunkier handle should make it easier to deliver force from your hand to the toothbrush head. I like to regulate the pressure that I press on my teeth with the toothbrush. In this Radius toothbrush, the thinner part of the handle flexes to assure the pressure does not exceed a certain amount. But sometimes, I'd have liked to press a little harder. Perhaps the toothbrush is smarter than me, and I should take its advice. Maybe I should always strive to flex the handle to assure I'm always exerting the proper force, as determined by Radius. The handle also has some zig-zags. I'm used to approaching my teeth with an angle determined by my arm and hand. So after a week, I'm still getting used to approaching my teeth with the strange zig-zags of this toothbrush handle. After a week, I'm still getting used to this toothbrush, trying to decide if I'll stick with it or dispose of it. The promise is getting the process, which I was never enthusiastic about, done faster with the toothbrush's huge head. So I'll keep using this toothbrush until I get used to it or give up. Least importantly, if you were ever able to hold a conversation while brushing your teeth with a traditional, little toothbrush, you won't be able to utter a single syllable anymore with a mouthful of this one. 2/2024 I signed up for a subscription, and my 2nd Radius toothbrush should be arriving this month. I'm still using it, no plans on giving it up. It's still a big mouthful. And the default 6-month replacement seems just right; thanks. I'm not sure why I haven't upgraded to an electronic sonar vibrating toothbrush, yet. One of my braincells probably remember their incredibly expensive replacement heads. Read more

These are the best toothbrushes

Old MacDonaldOctober 4, 2025

Best toothbrush on the market, they've been making these for many years and every dentist I tell about them starts recommending them to patients. They are easier for kids and people with dexterity problems to hold, and they brush the teeth and gums at the same time without irritating them. You can also get a travel case for them. I used my last one for 8 years before buying this one. Read more

Great Brush

Grandma of a bear cub boyAugust 21, 2025

These are the best toothbrushes ever! Took a couple days to get used to, but now I won’t use any other toothbrush! This design stimulates and cleans your gums and tissue too! I have receding gums and a bridge that is hard to floss, but this brush does a great job! Teeth feel really clean too! Will definitely buy again and have even given them to my grandkids! Read more

Good Gum Cleaner easier on the Hand to Hold

HarleyAugust 30, 2025

This looked like an Orthodontic Device but once you get used to how to use it, your Teeth and Gums will Thank You. You should not use pressure by the Gum area, just the large size of the Brush does come to the gum area to clean so the size is a helper. So easy to handle, just fits the hand easily. Its says Soft, but I found it almost a Regular. Read more
