Toothbrushes & Replacement Heads

• How do I remove and replace my RADIUS replacement head?

  Gently pull the head straight off—no twisting required. If it's tight, warm water helps loosen it.

• The Big Brush™/Flex™ Brush is too big for my mouth. Is the Source™ Toothbrush smaller?

  Yes—Source™ has a head about 50% smaller while still offering 200–300% more bristles than standard brushes.

• The bristles on my brush are falling out. What should I do?

  Bristles should never fall out—contact us for a replacement.

• What are the staples in RADIUS toothbrushes made of?

  The bristles are secured using a nickel‑silver alloy staple.

• What is the difference between the Pure Brush & the Totz® Brush?

  The Pure Brush has twice as many bristles and is softer for babies 6 months+, while Totz® is designed for toddlers 18 months+.

• Which RADIUS toothbrushes have replacement heads?

  The Source™, Big Brush, Big Kidz ® Brush, and Tour™ Brushes use interchangeable replacement heads.

• Why are RADIUS bristles end-rounded?

  End‑rounded bristles are smoother, safer, and gentler on gums.
