Meet the new & improved Grin Ultra Clean String Floss!

Made from a luxurious, resilient material that doesn’t tear or shred easily (same material as our original 30m mint waxed floss), naturally flavoured with mint oil, and comes in a 100% recycled dispenser and packaging.

Infused with coconut oil for a deep clean between the teeth. Coconut oil is naturally antibacterial!

  • Premium luxurious floss made from PTFE which is resistant from tearing/threading (a common issue with silk and PLA floss).
  • Coconut Oil Infused
  • Natural mint flavour - no artificial flavours, colours or preservatives.
  • Fluoride Free
  • 100% Recycled dispenser and packaging.  

Directions for use

Floss before brushing your teeth. Regular flossing can start as soon as two teeth are in close contact.

Children should always be supervised by an adult while flossing
