Supersized brush head for superior cleaning.

The wide oval brush head allows for 3x the bristles of your average toothbrush giving you a cleaning that will improve gum health and leave your teeth feeling tingly and fresh.

Award-winning “easy-grip” design.

That recognizable shape isn’t just for good looks — the Big Brush’s user-friendly handle complies with the dentist-recommended 45-degree brush-to-tooth angle and the smart Thumb-and-Palm design makes it much easier to grip and control.

A sustainable design that works.

From the plant-based, biodegradable cellulose handle sourced from renewable timber to the replaceable head to the vegetable-based nylon bristles, the RADIUS Big Brush is earth-friendly, 100% petroleum free and 100% effective in keeping your smile sparkling.

Great Toothbrush. Bad e-commerce experience.

I love the Original radius toothbrush! This review of the toothbrush is based on previous purchases and decades of using Radius toothbrushes, because I never received this order. I placed order and it took me to Shop Pay (Shopify) for checkout. But Shop Pay auto-filled shipping address with something from a previous purchase made at a different Shopify site...and that order was a gift for somebody...so my order was placed going to my previous gift recipient (perhaps a toothbrush is an interesting gift?!). No easy way provided to correct the error. I was able to cancel and Radius refunded me, but there were other issues beyond the initial which I won't get into for fear of sounding "whiny". So bottom line, great toothbrush but I'll buy at retail from now on.

The original and the best

The Radius original toothbrush is still the best I've used. It is very strong and solid, unlike the newer ones which have too much "give". The travel case is also quite durable.

Perfect Toothbrush - O.G. Radius

I’m very grateful for the return of the original Radius, and very much hope it will return to being a permanent member of the various Radius toothbrush options. Throwing in a travel case with each toothbrush is an awesome bonus. Thank you Radius!
