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!

Extra Soft Bristles Give You A Thorough Brushing

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.

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.

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”.

Great customer service . . . and products!
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
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.
Description

Give your toothbrush new life with RADIUS toothbrush replacement heads - the sustainable, interchangeable refills designed for SOURCE™ and  TOUR™ Travel Brush handles. With a wide, gum-massaging head and long neck for deep reach, these heads deliver our signature clean while reducing toothbrush waste by an incredible 93%.

 

These are replacement heads only and must be used with a compatible RADIUS handle.

Benefits

These toothbrush replacement heads feature 3,000 soft, plant-based bristles - up to twice as many as ordinary toothbrushes - for a fuller, more comfortable cleaning experience. The wide brush head gently stimulates gum tissue, helping to reduce bleeding and gum recession while supporting long-term oral health.

Choose from Super Soft Flossing, Soft, or Medium bristle strengths:

  • Super Soft Flossing bristles taper toward the tip to clean closer to the gumline
  • Soft & Medium bristles are end-rounded for a pillow-soft, enamel-safe clean

RADIUS bristles last up to 3× longer than conventional toothbrushes, reducing both cost and waste over time.

Materials
  • Plant-Based Nylon Bristles
  • Head base made with Nylon + EcoPure® (accelerates biodegradation in landfill environments)
  • BPA-free
  • PFAS-free

Packaging: Recycled PET (soda bottles) + recycled cardboard

Sustainability

These toothbrush replacement heads are engineered to reduce waste dramatically. By replacing only the head instead of an entire toothbrush, you cut down plastic use by 93% compared to conventional brushes.

Additional sustainability highlights:

  • Heads enhanced with EcoPure® for improved landfill biodegradation
  • Packaging made from recycled materials
  • Interchangeable design extends the lifespan of every RADIUS handle
  • Helps prevent millions of plastic toothbrushes from entering landfills

RADIUS replacement heads are a smarter choice for your oral care - and the planet.

30-Day Guarantee

We stand behind every RADIUS product. If you don’t fall in love within 30 days, return it for a full refund, no questions asked.
