The luxurious RADIUS® Original® blends form and function seamlessly. Not only is it accepted by the American Dental Association® for prevention of gingivitis and the removal of plaque, the RADIUS Original€™s iconic design won it a spot in the permanent collection of the Smithsonian Institute National Design Museum.


  • Supersized Brush Head for Superior Cleaning
    The wide oval brush head is designed to improve gum health and can even reduce the risk of gum and heart disease by massaging the whole mouth €” leaving you with that tingly-fresh feeling. It€™s like a trip to the dentist, every day and night.
  • 3X More Bristles
    Not only are there more of them, the Original€™s mass of bristles are softer and more uniquely aligned, providing even pressure that helps reduce chronic bleeding, receding gums and enamel erosion.
  • Award-Winning €œEasy-Grip€? Design
    That recognizable shape isn€™t just for good looks €” the Original€™s user-friendly handle complies with the dentist-recommended 45-degree brush-to-tooth angle and the smart Thumb-and-Palm design makes it much easier to grip and control.
  • Both Right Handed and Left Handed Versions
    The RADIUS Original€™s ergonomic design comes in right- and left-handed versions, so everybody can enjoy a luxurious teeth-cleaning experience.
  • Sustainable from the Start
    From the cellulose handle sourced from renewable timber, to the vegetable-based nylon bristles, the RADIUS Original is 100% petroleum free.

     At RADIUS® we do things a little differently.

    Just like other everyday products that have €œevolved€? through beautiful, functional design (think Dyson vacuum cleaners and Lumbar chairs), every one of our products is totally unique €” devised for a specialized purpose, utilizing different materials and one-of-a-kind manufacturing techniques €” because refining and evolving the tools of your daily life is what we€™re all about


    Bristles that are better for you

    RADIUS wanted to steer clear of the petroleum-derived versions used by most other toothbrush manufacturers, which are saturated with harmful chemicals  and toxins you wouldn€™t want  going anywhere near your mouth. We also  decided to omit natural bristles from our  toothbrushes, as they€™re typically harder and  harsher on the gums, and break frequently  and easily.   


    Our solution is to use dye-free  bristles made from vegetable-  based nylon, shipped all the way from Europe to our specialist bristle manufacturer.  

    Made from castor oil, they absorb very little moisture and have the ability to bounce back to their original shape after use, making them softer and longer-lasting than the alternatives. 

     Bioplastic handles that are better for the environment

    Most toothbrushes use common plastics €” such as fossil-fuel plastics derived from petroleum €” to construct their handles. It€™s the standard way of doing things, but RADIUS toothbrushes are anything but.

    At RADIUS, we use bioplastics, which are derived from renewable biomass sources (like vegetable oils and timber), agricultural byproducts, or even recycled plastic. Why is this so important? Because bioplastics are not only better for your health, they€™re better for th e environment, as well, requiring less fossil fuels and energy to produce (resulting in fewer greenhouse gases). Plus, they€™re mostly biodegradable, so they won€™t contribute to long-term waste in our landfills.

    Here€™s a breakdown of our most popular toothbrushes and how their handles are made:

    • For the Original® we use cellulose, derived from sustainable-yield forests. The supple SCUBA® has two high-tech, lightweight, oil-based materials (no natural substitute exists) as well as recycled-rubber, that are flexible under pressure. That€™s why we recommend it for more heavy-handed brushers.
