How long will it take for my big little brush to arrive?

What bristle firmness should I use?

Dentists recommend (truly, we asked them!) a soft bristle best for removing plaque and debris from your teeth and to prevent damage to your gums, root surface, and protective tooth enamel. However, we also supply medium bristles for those who need a little more oomf.


How long should I use my big little brush for?

Your brush should only be used for 12 weeks or until you notice the bristles becoming frayed (don’t go too hard soldier, you’ll hurt your precious gums!). That’s the beauty of our 4 pack of brushes, you’ll be good to go for a 12 months.


The bamboo handle is slightly changing colour, is this ok?

Yes, it’s 100% safe and normal if you see the bamboo lighten slightly. It’s a natural material (vs. plastic) and therefore you may see a slight change in its colour

As the bamboo ages, if it feels dry on your skin try running it under the tap to wet completely.


So you said these brushes are biodegradable, what do I do with them when they’ve finished?

They certainly are! But first, you need to chop off the bristles and dispose of them in the bin, as Nylon 4 won’t decompose in normal compost. Then throw the handle in your compost or bury it in the garden.


Where does big little brush share/spend its profits?

Every time you buy a big little brush, you are helping to fund health and human development initiatives in developing communities. So far, we’ve been able to financially support Indigie Grins and Red Dust to provide oral care education to kids in remote or disadvantaged communities. The more brushes that we sell, the more we can support these worthy causes! If you’d like to know more about these organisations and our work with them, here’s the full story.


What the heck is Nylon 4?

Sounds like we made it up, right? Well no, Nylon 4 is a petroleum-based plastic that has been shown in lab studies to biodegrade between 3 – 4 months in the environment under certain conditions.

Can I return my order for any reason?

Sure can, check out the deatails of why and how on this page.
