  • Q. What is Grin toothbrush?

    A. Grin is a premium quality, eco-friendly, manual toothbrush. Grin was founded by Simon Cooper, who wanted to make a better toothbrush and reduce plastic waste.

  • Q. What are the benefits of using Grin toothbrush?

    A. There are several. First, using Grin means you’re contributing less plastic to landfill and our natural environment. Grin’s replacement brush heads use 4 grams of plastic, while most disposable toothbrushes use 20 – 25 grams. Unlike disposables, Grin’s brush heads are recyclable (by removing the bristles).

    Secondly, Grin uses premium quality, tapered bristles that penetrate deeper than most drugstore brands. This means cleaner teeth and a healthier smile.

    One of the easiest ways to prevent gum disease is by replacing your toothbrush regularly. This is why Grin sends you replacement reminders to replace your toothbrush head every 3 months.

    Lastly, for every Grin toothbrush sold, $1 is donated to a charitable organization.

  • Q. My brush head is hard to remove from my handle.

    A. The brush heads are meant to fit tightly into the handle. To remove them, pull hard with your hands or use pliers if needed. Insert your new brush head by pushing it into the holes until it is tight. 

    We guarantee Grin toothbrushes – so if you continue to have problems, please contact us at

  • Q. What's the difference between Grin and a regular plastic toothbrush?

    A. Grin is a two piece toothbrush that we deliver to you in the mail. The aluminum handle is guaranteed for life, so you only need to replace the brush heads. Plus, Grin’s brush heads are recyclable – just remove the bristles with pliers and add the brush head to your blue box. (One disposable plastic toothbrush uses as much plastic as six Grin brush heads!)

  • Q. What is the handle made of?

    A. Grin’s handle is made of aircraft-grade aluminum (6063-T6). Aluminum is lightweight, durable and safe to use. Aluminum is also infinitely recyclable, meaning it can be used over and over without losing quality. 

    Because aluminum is so light, it means less energy is needed for shipping. The colour is an anodized finish, which is NOT paint or powder coating. Anodization means the colour is bonded to the metal using an electrochemical process that’s durable, corrosion-resistant and safe. 

  • Q. What is the brush head made of?

    A. The brush heads are made of Polypropylene, which is safe for oral use and 100% recyclable. Our bristles are made of nylon. They’re special, soft tapered bristles, which penetrate deeper between your teeth than regular bristles.

  • Q. How much does shipping cost?

    A. Shipping is free.

  • Q. Where can I buy brush heads?

    A. At this stage, we are selling on our website. 

  • Q. Why do you claim Grin collects fewer germs?

    A. Unlike drug store toothbrushes, Grin’s handle and brush heads are smooth—no ridges and grooves for ‘grip’—meaning nowhere for germs and bacteria to accumulate. Don’t believe us? Take a look at a plastic toothbrush that is a few months old. See all that white gunk in the grooves? That's a lovely mix of old toothpaste, saliva and bacteria. 

    Plus, Grin is flat on the bottom so when you put it down it doesn’t roll over and expose the bristles to germs found on bathroom surfaces. 

  • Q. What happens if I scratch my grin handle?

    Don’t worry! We call that character. Because the handle is anodized, you don't have to worry about paint or chemicals, however if you find your handle has been scratched, rinse it well to make sure no aluminum chips are left on the handle or in the bristles. 

  • Q. When will you offer children's toothbrushes?

    We plan to start making children's toothbrushes, but Grin is still a very young company so at this time we can't put a timeline on producing any. If you sign up for our newsletter you’ll be one of the first to find out when they’re available.
