  • Options: Right hand, left hand, or a 2-pack of replacement heads
  • Replace head: Every 3 months

Radius Big Brush Toothbrush Benefits

  • Wide clean — More bristles cover more tooth surface with each stroke.
  • Gentle on gums — Soft bristles massage the gumline as you brush.
  • Made for your hand — Right- and left-handed shapes give a natural grip.
  • Keep the handle — Replace only the head, which means less waste.
  • Plant-based materials — Handle and bristles use renewable and bio-based sources.

How to Use

  1. Apply a pea-sized amount of toothpaste.
  2. Brush teeth and gums in small circles, working away from the gumline, for two minutes twice a day.
  3. Every 3 months, pull off the old head with a firm tug and press a new one onto the handle.

Who It's For

  • Adults who prefer a large, soft brush head
  • Left-handed brushers who want a brush shaped for them
  • Anyone cutting down on plastic toothbrushes

Why Radius Big Brush Toothbrush Works

➕ Why a bigger head?
A wide head with more bristles touches more of each tooth at once, so brushing feels thorough without pressing hard.
➕ Why a hand-specific handle?
The angle of the handle follows the way your wrist naturally moves, which helps you reach the back teeth comfortably.
➕ Why replaceable heads?
The handle is built to last, so you only replace the small brush head instead of a whole toothbrush.
