What will I notice when I change from mainstream toothpaste to Grin?

What’s the difference between Bamboo and corn-starch?
Preference. We developed our bamboo brush 3 years ago and is now extremely popular. However, some people don’t like the texture of the wood so that’s why developed a new eco-friendly alternative using corn-starch.Bamboo being a natural wood can also be susceptible to mould if left in water or damp areas. Our corn-starch toothbrushes are 100%mould proof.
I’ve had a bamboo brush before and all the bristles fell out?
Can you recall if it was a Grin Bamboo brush? Since we launched ours, there are now many companies doing them. We always get positive feedback stating that our bristles hold well and don’t fall out in your mouth.
What are the bristles made of?
PBT (polyethylene terephthalate), these are premium bristles that we use and are the most advanced in synthetic bristles. Majority of toothbrush bristles are made of Nylon and many claim they are recyclable however this is not the case.
Why are the bristles not biodegradable?
To be biodegradable the material needs to come from either plants or animals. The only truly biodegradable bristles available are boar (pig) hair.
Are the brush handles home compostable?
Both our bamboo and corn-starch handles are fully biodegradable. The bamboo will easily breakdown in a home compost or garden in approx. 12-18 months.
Our corn-starch handles are able to break down at home, typically taking between 24-36 months, however these require a more consistent environment. This means there needs to be a good balance of temperature, moisture and oxygen present. We recommend our corn-starch toothbrushes be sent to commercial composts as this is the most effective method. There are currently only a handful of commercial composts across the country, as they’re still relevantly limited here in NZ, so customers are welcome to send them back to us through our recycling program where we send them off to a commercial plant.
How do I remove the bristles?
Before putting your brush into the compost, you can remove the bristles by either using pliers, or snapping off the toothbrush head.
What if I don’t have a home compost?
There are two easy options for customers who don’t have a home compost:
Home compost services are available throughout the country.i.e.co.nz – For$10 per/week they will come and collect all your compostable waste and deliver it to a commercial compost facility.
Customers can send their used brushes into the Grin Recycling Program for free

Why do you infuse your brushes with Charcoal?

Are the Charcoal-infused brushes safe?
Yes, they are 100% safe for all ages. The reason we don’t infuse our kids’ toothbrushes with charcoal is because young kids often don’t like the dark bristles and are used to the clear ones.
