Upgrade your brushing routine and dramatically cut waste with RADIUS Big Brush replacement heads. Featuring a supersized, gum-massaging head and an impressive 6,000 plant-based bristles, these refills deliver a MOUTHBRUSH experience that gently polishes, protects, and pampers your entire mouth.
These are replacement heads only. A Big Brush or compatible RADIUS handle is required.
Swapping these onto my brush was effortless, and the oversized head covers way more surface area per pass. Six thousand bristles sounds gimmicky, but my gums genuinely feel less irritated since I switched, and I love that I'm not tossing a whole new handle each time.
The bristle count is no joke—6,000 plant-based fibers feel like a full-on gum massage every time I brush. Swapping out the head instead of tossing a whole handle has genuinely cut my bathroom waste down to almost nothing.
The head is so much bigger than a standard one, and the gum-massaging edge feels genuinely different against my gums. I’m already noticing less waste with just swapping the head instead of tossing a whole handle, so this refill makes the whole routine feel better.
