MOST AWESOME TOOTHBRUSH EVER!!!

A. November 5, 2025

I was visiting a friend in NY, and all her family had these gigantuous toothbrushes. I was spitting with her and making fun of how large they were, and she said , “Don't knock it till you try it. I thought the same thing.”. So she bought one for me, while I was there (that was in 2009). I WAS SOLD!!! (even though it felt unusual at first due to the size) I've been using them EVER SINCE! It feels absolutely abnormal to put a standard size toothbrush in my mouth! My mouth feels as if I am able to do such a better job of getting everywhere! I allllways brush my tongue and rod off my mouth also, and this just has MUCH better coverage for that as well. Thank you for such a unsuspecting (I'd never seen them before her house) but great product, Mucho mucho KUDOS!!! The only negative is when I buy replacement heads, the replacement heads are soooooo much smaller than the ones that come when you purchase the entire brush. I purchase them (brush and heads at our local health food store. That has been very frustrating, because I have felt forced to purchase a new brush each time. But as far as brushing teeth, there's not a better toothbrush in my opinion! 100 stars! ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

Personally essential

Al October 1, 2024

I can understand how size of the toothbrush head might be jarring for some, but it is the perfect sensory experience for me as an autistic adult. It takes up proper space, the bristles are soft enough not to hurt but sturdy enough to get the job done, the handle is excellent for my level of motor skills... I've struggled to brush my teeth all my life and now I don't struggle anymore. It's pricey-- sometimes too much for me to afford-- but it's absolutely essential to my routine. I highly recommend RADIUS to anyone who needs to change the sensory experience of brushing their teeth.

Swap of Handles Brings Joy to family in NZ

Stu S., the OPSHOPPER May 12, 2023

The replaceable head Radius toothbrush is both a beautiful object and its use over the years means our family can be more environmentally friendly. Using the Replaceable brush saves a heap of money over the cost of an equal number of Radius' regular brushes and as we don't dispose of a whole brush (handle with brush attached) it means that less plastic will wind up on our beautiful New Zealand beaches! I bought two of the Coral handled replaceable brushes for my wife who dutifully returned to me a black handle replaceable brush which did not match her boudoir color scheme. I have made her happy and me too! Thank you, Radius. We rave about the effectiveness of the Big Brush - proven by our recent visit to our dental hygienist who gave us high marks for the quality of care we take with our teeth. Brushing and flossing twice a day does the trick along with two visits to the hygienist yearly. We recommend Radius to everyone whenever we can!

Uniquely valuable for people with hand tremors

Michael August 29, 2025

This is a review of the Radius Big Brush, in two parts, the first part general and the second part specifically addressed to people with hand tremors, in particular people with essential tremor. 1. I've been using the Radius Big Brush for many years. I find it exceptionally satisfying, in that it gives the gums a pleasant massage, and the bristles have just the right degree of yield. 2. For people like myself, who have so-called essential tremor, or I would think any type of hand tremor, the Radius Big Brush design is uniquely valuable. I have had essential tremor since childhood (yes, that's possible), and this brush design has solved problems with toothbrushing that I had for much of my life: it greatly reduces the need for precision in placing the brush so as to brush the gum line, and it eliminates the rigid part of the brush knocking into the teeth. A supplementary remark for anyone who works in a hospital: because the Radius Big Brush Is so helpful for people with hand tremors, I regard it as being a prosthetic for people with this problem, and I think any hospital would be well advised to carry a stock of Radius Big Brushes, so as to be able to give one to any patient with hand tremors who is not already aware of this product. Please note that these remarks apply specifically to the Radius Big Brush, not to the Radius product with the small brush head; the small brush head is not especially helpful for people with tremors.

Love love love!

DinaK September 27, 2025

I got this toothbrush from a value market. OMG! The whole family loves them. The feeling of freshness, cleanliness and comfort is amazing. They all happen to be left handed, but they are still comfortable and easy to use. Bonus that they are made in the USA. This is what we will be using from now on. Thank you!

Pretty goid

MaryEllen November 11, 2023

I'm ambidextrous and prefer the left handed version. I'll use this bigger brush to clean all teeth,mouth tongue,but fine tune my brushing with the smaller head tooth brush so I get back teeth as my mouth is smaller. This big brush is for the lazy times when I don't feel like brushing for 2 min. It works for my needs, changing brush head after a few months use is difficult so my husband tends to that. Bristles last many months, weekly disinfect with peroxide. Delivery and price point good

Great Product, But Not Without Small Flaws

CHILL July 22, 2023

Great replacement for my older one. Somehow, I feel like my toothpaste doesn't foam up as much with this one. My older ones weren't replaceable heads and might have had more bristles? I'm hopeful that it will just take some time and foam will return, but either way I do think it's getting the job done. Also, worth noting that this style/color has a wart on the back of the brush that is unfinished - likely the results of the material or the 3D printing process. I wish it would have been polished over. It is defined and clearly seen in pictures though.

Put a Replaceable Head on a Scuba Handle—Perfect!

PJ Master Diver December 22, 2025

The replaceable head is a useful feature, I ordered two extra. However, in the past I ordered several "Scuba" style brushes, which I really prefer. Why? The handle on a Scuba toothbrush had a bit more flex in it; the thumb indentation had grooves that held your hand better; and the texture of the handle was more tactile, less prone to slip when wet, unlike the newer Big Brush that is hard plastic and harder to hold when wet.
