More Amazing Details

A deeper clean while massaging your gums.

Our toothbrush head was designed with radiating bristles embedded in a curved bristle bed and connected to a longer neck so that you get a deeper clean and a stimulating gum massage all at the same time. It’s a smaller head than the Big Brush and Flex Brush but the bristle design means the same gum stimulation and massaging benefits. Choose your bristle type! Our Super Soft Flossing bristles are tapered to get closer to your gum line while our Soft and Medium bristles are end-rounded for a pillow-soft clean.

Refillable replacement heads, means less waste and lower cost.

Replaceable head means 93% less waste than the average toothbrush. No need to sacrifice a clean mouth feel for a cleaner planet. With the durable Source handle made from repurposed recycled materials and it’s replaceable long neck head, get the cleaning you want and keep our beaches looking fresh too.

So comfortable you won’t want to let go.

An ergonomic reversible handle design is suited for righties and lefties and reduces unwanted pressure on your teeth and gums. Also, each handle model has its own unique eco-friendly personality, sourced from different repurposed materials.

Love this toothbrush

2 months ago

I find the Source toothbrush comfortable in my hand. The soft bristles are just right. They clean my teeth well and are gentle on my gums. I also really like the fact that only the head is discarded since the handle is reuseable. It is sufficiently sturdy that it will last for years.

Radius toothbrushes are the GOAT

6 months ago

I have now bought and tried every adult toothbrush and can say I LOVE them ALL!! The source brush is great with a sturdy handle and the soft flossing head works really well to get in between the teeth. It’s a little too soft for my liking but easy fix to use a different replacement brush!! I appreciate the fact that all the brush heads are interchangeable. My fave combo so far is the source toothbrush handle with the big brush replacement brush!

Yes, I recommend this product.

Extra Soft Bristles Give You A Thorough Brushing

8 months ago

The extra soft bristles help people with sensitive gums minimize that sensitivity, while still receiving a thorough removal of plaque. The thinner bristles actually make cleaning between the teeth easier.

Yes, I recommend this product.

Absolute best

8 months ago

Love the extra soft bristles and their flossing design. I always get praised at my dental cleanings. These replacement heads can be hard to find at my local stores, so I bought six 2-packs to last a long time.

Yes, I recommend this product.

The best

10 months ago

The best toothbrushes ever. I was honestly a little surprised reading all of the bad reviews because I’ve been using this for over 5 years and have the same 2 handles, one for home, and one for travel. They have both lasted me that long. So I don’t understand how other people say that their handles break or don’t last, maybe they’re just being too rough with it? I don’t know. The other thing is, I don’t have trouble with my bristles “falling off”.

Yes, I recommend this product.

Great customer service . . . and products!

11 months ago

This is my second complete brush as the first one wouldn't come apart to change the brush head. I contacted Radius & shared my dilemma & they sent me a brand new complete brush as well as a travel case, at no charge. I am truly grateful for & impressed with their products and their customer service. I'm happy to have found this company as I am trying to reduce my use of plastic.

super soft replacement head

a year ago

Have been using Radius for many years but this was first purchase of super soft bristles. The uneven cut of the bristles works great for loading it with tooth powder since I switched from paste. Really comfortable clean for teeth and gums.

Frequently Asked Questions

Answers to common questions to help you understand things better.

How often should I replace the head?

Every 3-6 months or when bristles show wear. Just pop off the old head and click on a new one. A RADIUS replacement head toothbrush can last up to 3x longer than other brands, but the life of your toothbrush depends on how hard you brush and how often.

Are the bristles soft?

Yes. The Source™ comes in Super Soft Flossing, Soft, and Medium bristle types. Our Super Soft Flossing bristles are tapered to get closer to your gum line while our Soft and Medium bristles are end-rounded for a pillow-soft clean. Our wide heads have over 3000 plant based bristles to help cover more surface area, protect enamel, and improve gum health all in one deep cleaning toothbrush.

Is the RADIUS Source™ Toothbrush biodegradable?

Each RADIUS Source™ Toothbrush is a biodegradable toothbrush made from renewable, recycled materials and plant based components, sustainable by design. In addition, all RADIUS toothbrushes contain EcoPure®, an organic additive that helps products biodegrade more quickly in landfills. A material without EcoPure degrades at a rate of 3.2%, but a material with EcoPure degrades at a rate of 40.2%. That’s a significant change!

Where is the RADIUS Source™ Toothbrush made?

Every Source™ Brush is crafted in the USA at our Pennsylvania facility using low-energy machines, a commitment to sustainability from handle to bristle.
