Good to know: For a soft brush, the Gentle Care duo from the same Grin Pro range has soft, 0.12 mm tapered bristles.

A pair of Grin Pro Ultimate Whitening toothbrushes, each with a head that combines a T-zone of spiral bristles, a rounded-end core and an outer ring of tapered bristles.

Designed to help lift surface stains, the Ultimate Whitening Toothbrush Duo delivers a premium clean that leaves the whole mouth feeling fresh.

This advanced brush head features three bristle types working together for a powerful clean: a T-Zone of spiral bristles helps maintain even pressure from front to back, a core of rounded-end bristles helps lift surface stains, and an outer ring of tapered bristles reaches between the teeth.

Crafted for daily use. The handle is made from recycled post-consumer plastic, and the duo pack makes it perfect to share or rotate.

Why you’ll love it:

  • Triple Bristle Technology: spiral, rounded-end and tapered bristles on one head
  • T-Zone Spiral Bristles help maintain brushing consistency across the whole mouth
  • Rounded-End Core Bristles help lift surface stains
  • Tapered Outer Bristles reach into tight spaces for a thorough clean
  • Handle made from recycled post-consumer plastic

How does a whitening toothbrush work?

It works on surface stains only. Each head combines a T-zone of spiral bristles, a rounded-end core and an outer ring of tapered bristles, and the rounded-end core is designed to help lift surface stains. It does not bleach the teeth.
How firm are the bristles?

Medium. This is the firmer of the two Grin Pro Ultimate duos. For a soft brush, the Gentle Care duo from the same range has soft, 0.12 mm tapered bristles.
What makes it a duo?

Two toothbrushes in one pack, so there is a spare for the bathroom drawer or one for a second person. Both have the same three-bristle head and a handle made from recycled post-consumer plastic.
Who makes Grin?

Grin is an oral care brand based in New Zealand. Alongside this toothbrush duo, we stock toothpastes from its Pro range and its Pro Ultimate toothbrush duos.
Can I use it with any toothpaste?

Yes, it works with any toothpaste. For a paste that also helps lift surface stains, Grin Pro Toothpaste + Hydroxyapatite and Grin Pro Toothpaste + Fluoride both contain papain and bromelain fruit enzymes.
How often should I replace it?

Replace the brush every three months, or sooner when the bristles start to splay. With two brushes in the pack, the second is ready when the first is done.

Great toothbrushes. The bristles are the perfect softness - not too harsh, not too soft. My teeth feel clean after every brush. The duo pack means I always have a spare. Good quality for the price.
