Super-charged to clean up your mouth and our world, the Big Brush™ handle is reusable forever – just replace the brush head! The Big Brush was engineered to protect your mouth and our environment in the days to come.
Supersized, gum massaging design.
The wide oval brush head is designed to improve gum health and can even reduce the risk of gum and heart disease by massaging the whole mouth — leaving you with that tingly-fresh feeling. It’s like a trip to the dentist, every day and night. Pair these replacement heads with our Big Brush™ or our Source™ Brush.
A longer lasting brush.
These brushes are designed to last longer than the average toothbrush. That means you get a better cleaning and create less waste.
Replacement Head for reduced waste
By using a Replacement Head, 90 out of every 100 toothbrushes escape the fate of the landfills. Your forever handle is made from renewable timber and designed to last. Help us turn the tide on the plastic epidemic that litters our fields and clogs our oceans.

What people are saying.
Great product. Nice to be able to replace just the head without trashing the entire toothbrush!
Big Brush Replacement Heads (2 pack)
I have been using the radius toothbrush for well over 20 years, and couldn’t possibly go back to a regular brush!!! I like the fact that I can just replace the heads instead of throwing away the big plastic brush.
Love Radius products, including the Big Brush Replacement Heads which save me money.
