Cruelty Free

Cruelty Free is a certification process through PETA that labels products that are not tested on animals. All companies that are included on PETA’s cruelty-free list have signed a statement verifying that they don’t use ingredients or create finished products that help conduct or pay for any tests on animals.

Phthalate Free

Phthalates are found in toys, electronics, personal care products, plastic wraps, containers, and more. These petroleum based chemicals help soften plastics, and bind fragrances to perfumes, deodorants, creams, and other personal care products. Phthalates are are not chemically bound, meaning they can easily get released into the air, water, or your body, just by using the products as intended. Phthalates have been found to disrupt the endocrine system, which can cause reproductive damage, hormonal imbalances, infertility, mood changes, metabolism changes, and more.

Leaping Bunny

Cruelty Free International certifies that cosmetic and household products are not tested on animals. These companies are audited to ensure that the ingredients and finished products are not causing harm to animals.

Sustainable Lifestyle

This product helps promote a more sustainable lifestyle. Whether it encourages re-use and the movement away from disposable products, or it promotes sustainable actions like recycling and composting, this product can help you lower your environmental footprint.


This product does not contain any animal products or byproducts, and has not been tested on animals.

Sustainable Manufacturing

Some or all of the energy used to make this product is produced via renewable energy sources such as solar, wind, or hydropower.

BPA Free

Products that are labeled as BPA free do not contain Bisphenol A, a chemical commonly found in plastic products. Studies on BPA exposure have shown that high levels of BPA could lead to hormone disruption, effects on behavior and brain function, reproductive problems, breast cancer, heart disease, infertility, and more.

Made in the USA

This product was made in the United States. Buying locally made items helps to reduce harmful emissions that result from transportation during and after the production process. Purchasing products made in the United States also ensures that the items are produced in ways that meet strict safety and labor standards.

Plant Based Resin

Plant Based Resins are used as an alternative to fully-synthetic plastics. Instead of using Petroleum as the main base ingredient to form plastic, some companies have started replacing a portion of the ingredients with plant and vegetable extracts. This lowers the amount of resources extracted to create purely synthetic products, and often provides a use for agricultural byproducts such as corn or flax. Some plant based resins are made from 100% plant materials, and can be composted in industrial facilities. EarthHero recommends checking with your local compost facility to determine which items are safe to compost.

Recycled Content

Recycling is the process of taking an otherwise-discarded item or material and cleaning, sorting, and breaking it down into its basic form (such as fibers or pellets). This material is then used to produce new items. Recycling keeps useful materials from being discarded in landfills, prevents resource extraction due to the creation of new materials, and provides a new life for used items. Recycling can utilize both pre-consumer waste (materials left over from production) or post-consumer materials (used clothing, empty water bottles, etc). This product is made from recycled content.

Like nothing else on the market, the Soft Source Radius Toothbrush is revolutionizing the way we brush, thanks to replaceable bristle head technology and a one-of-a-kind upcycled content handle. Vegetable based nylon bristles form a curved bristle-bed, massaging the gums rather than aggravating them. Repurposed wood, paper, and even recycled dollar bills go into their ergonomic handles, designed to reduce pressure on teeth and gums for optimal oral health and a minimalist aesthetic. Plus, the unRead Morebreakable slim neck is longer than your average brush, getting into nooks and crannies for a maximum clean! When it's time to change toothbrushes, just switch out the head with a RADIUS Source Replacement pack. This is truly the last toothbrush you'll ever need!

About the Company


At RADIUS, they don’t do anything halfway. By taking a holistic approach to designing and manufacturing products, they’re able to stay rooted in their commitment to sustainability and a reduced carbon footprint. Before they create a product, they do a “360 degree evaluation”, considering the entire life cycle of the product from birth to end of life. This evaluation is just one of the many reasons that RADIUS toothbrushes consistently outlast the competition.

By manufacturing locally in the USA, they ensure maximum quality products with less transportation emissions. All products are made small-batch style on low-energy machines, recycling damaged or imperfect toothbrushes, and eliminating waste as much as possible. Instead of using traditional plastic, they employ bioplastics, derived from renewable biomass sources like vegetable oils or used plastic bottles. Not only are these materials better for the environment, but they require less fossil fuels and energy to produce! Click below to learn more about why EarthHero loves RADIUS!

    Very pleased

    cawrightfesser (verified owner)

    Both the head and handle are larger than what I was used to, but I find that the handle actually fits my hand extremely well and makes holding the brush on moderate arthritis days much easier. There is a slight molding line that, if it becomes a nuisance, could easily be filed or scraped down. The head itself is a little large, as I said, but after a couple weeks I’ve adjusted my brushing pattern and don’t even notice anymore. Very happy I made the switch to this toothbrush.

    Coconut Shell Toothbrush

    I already have the wood handle..didn’t know there were others until Earth Hero. I bought the coconut for travel & love them both. It’s a great idea as well as I love the white toothbrush head & groovy handle.

    Best brushing experience I've ever had

    eliscollingwood (verified owner)

    I’ve had a history of neglecting oral care due to mental health issues. During 2020, I’ve made significant progress in tackling those issues which has made it easier for me to start taking care of my teeth. For about a year or so, I have been using a bamboo toothbrush. The bristles were really rough on my gums. Sometimes irritation would happen because I have a bad habit of brushing my teeth too hard, but even when I would consciously be gentle, my gums would still bleed. I decided to get this toothbrush due to its listing as soft yet sustainably made toothbrush and because other reviews had said it’s been really gentle on their sensitive gums.

    This toothbrush outperformed my expectations. The handle is so much more comfortable than my old wooden one. The length of the brush and the width of the brush head is also appropriate. I don’t have to spend as long going over my teeth/gums as I did with my previous toothbrush. And the acrylic/plastic (?) head is a much smoother and more enjoyable experience when brushing compared to the bamboo I was used to. Most importantly, it’s super gentle on my gums. There was immediate improvement in the health of my gums after using this toothbrush. While there’s still some irritation, the irritation itself was not caused by the brush. It’s just left over from my previous neglect it seems.

    I will say that the wideness of the head of the brush may be a bit off putting for some people – especially when brushing the back of one’s teeth – but it’s really not an uncomfortable adjustment.

  5. mountaintricia

    A bit large

    mountaintricia (verified owner)

    Both the handle and bristles are a bit cumbersome as they are so large. It does sound like a Great company to support so maybe I would buy again if I get used to the size.

      Hi Maria! While these toothbrushes help lower plastic waste by eliminating the need for an entirely new toothbrush, the head is not recyclable, unfortunately. Thank you for asking!

    Doesn't Hurt My Gums

    JewelSowers7 (verified owner)

    This toothbrush is so soft and it cleans my teeth very well. First use and my teeth were super smooth! It just gives you that clean feeling. I paired this toothbrush with the Ginger Citrus Organic Coconut Oil Toothpaste, and not only did it not give my mouth that funny after taste, it is whitening my teeth! What I love the most about this toothbrush is that it doesn’t hurt my gums, given that it is a “soft” toothbrush, but I have had toothbrushes before that would scratch my gums and make them sore for a few days , sometimes even making them bleed. Please note: I do not brush very hard, so it was not me that made my gums bleed with the other toothbrushes. Last things to say, this toothbrush is very gentle and I look forward to brushing my teeth before bed and after I wake up in the morning. I would definitely recommend this toothbrush.
