Customers find the toothbrush effective, with one mentioning it can clean top and bottom teeth separately.

★★★★★

You’ll never go back to a regular toothbrush after you try a radius!

Customer—October 9, 2025

I love Radius big brush toothbrushes, especially the ones with the original brush head! I’m a woman with a small to average mouth and this brush size is perfect and easy to use. I can brush top and bottom teeth separately or I can brush both at once in a time pinch and it still cleans my teeth well. Blue is my favorite color and this is a pretty shade of blue. Radius makes a durable, great quality brush. Don’t forget you must order either a right or left handed brush! You won’t want to go back to a regular toothbrush after you use Radius and it’s an attention getter of a toothbrush. People who see it will ask about it. Read more

★★★★★

Everyone should be using these!

Jon S.—September 25, 2025

Best toothbrush ever. I’ve been using these for the last 15 years and they really work and last for a lot longer than regular shaped toothbrushes. My mouth feels waaaay cleaner after every brush. Read more

Fixed head, easy to travel with, sleek design.

CeSaxon—March 29, 2023

I travel 8-10 months out of the year. This brand has never let me down. I’ma lefty, so it’s ergonomic handle is perfect for me. I’ve tried Radius replaceable head toothbrush (it traps a lot of gook between the sections). The travel toothbrush is ok but flimsy. This a fixed toothbrush gives you a good clean and the case keeps your toothbrush of hotel counters which is a major plus for me. The toothbrush itself is solid hard plastic, with a smooth durable feel to it. The bristles are soft and won’t hurt your gums. I get a good clean while using this toothbrush. Very satisfied with my purchase. I would buy again. Read more
