Cleaning your mouth and our environment at the same time

The idea is pretty simple…if you make a quality product, it will last longer and people won’t need to throw it away. Our products are made to last which means they are being used longer and not filling up the landfills while still providing you with the excellence you have come to expect from Radius.

The bristles are really gentle and so comfortable to brush your teeth! Will buy replacement heads in the future.

I bought this toothbrush because it helps you have less waste, with the replaceable heads, and I still love it for that. The only thing I don't love is that the head wears out really fast and I had to replace it in a short time.

Thanks for your feedback!

I love it!

I LOVE this toothbrush! 1) feels like you clean better and faster due to the size 2) massage your gums while your at it 3) perfect hardness of brush, not soft and not hard 4) ..it even looks cool! :) I ordered 1 of the medium and one of the soft only to get one of each color, but both of the ones we received were gray. Not an issue, but if I bought these in the store I would have picked different colors (for my man and me). They ship out random colors Also uses this brand for our 14 month old daughter. Love all the products so far!
