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.

Gum massaging bristles.

The unique curved bristle-bed ensures our plush bristles clean and massage the gum rather than aggravating them. 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. Pair these replacement heads with our Big Brush™, Source™ Brush, or TOUR™ Travel Brush.

Premium, eco-friendly bristles.

The soft bristles are made from vegetable-based nylon to reduce our dependence on fossil fuels. The bristles are arranged in an elegant fanned shape, designed to gently yet thoroughly clean and invigorate the entire mouth.

Frequently Asked Questions

Answers to common questions to help you understand things better.

Can toothbrush heads be recycled?

No. All brands use metal staples that prevent recycling. RADIUS uses EcoPure® to ensure enhanced biodegradability in landfill environments.

How do I remove my Replacement Head from the handle?

Pull the head straight off without twisting. If tight, run under warm water for 30–60 seconds. Avoid tools like pliers, which can damage the handle.

Which bristle strength should I choose?

Super Soft Flossing: Best for sensitive gums and gumline cleaning | Soft or Medium: Best for a classic, cushioned clean

Are these toothbrush replacement heads compatible with all RADIUS handles?

Yes - they work with SOURCE™, TOUR™, Big Brush™, and Big Kidz Forever handles.

How often should I replace my toothbrush head?

Every 3–6 months, or sooner if bristles fray. RADIUS heads last up to 3× longer than typical brushes.

Are these heads safe and non-toxic?

Yes - BPA-free, PFAS-free, and made with plant-based bristles and EcoPure® technology.
