Why Natural Toothpaste

At Grin we’re all about what we leave in, what we leave out, and how we leave your teeth. Our formulation is 100% natural, and can be used to help prevent tooth decay and to help keep the mouth healthy - because toothpaste needs to get the job done.  


What is it?

Health Benefit


Often referred to as “bee glue”, propolis is resinous mixture that honey bees collect from tree buds, sap flows, or other botanical sources.

Propolis offers antiseptic properties to help keep the mouth healthy. 

Manuka Oil 

Extracted from the leaves and small branches of the Manuka tree (Leptospermum scoparium), which is native to New Zealand.

Studies suggest that the anti-septic activity of Manuka Oil may help in the management of good oral health.

Organic Sea Salt  

When salt is certified organic the certification refers to the process of collection of sea salt.

Regular rinsing and gargling with tepid sea salt water helps to manage oral hygiene and to soothe an irritated mouth. 


A flowering plant species in the carrot family. Fennel is a hardy, perennial herb with yellow flowers and feathery leaves.

Fennel has been in use in culinary applications and as a mouth freshener since ancient times.


A organic compound made synthetically, or obtained from corn mint, peppermint or other mint oils.

Used to help with soothing an irritated mouth or throat.


A herbaceous perennial plant with a square-shaped stem, broad leaves, and white/pink flowers.

Our commitment

Our commitment you is also defined by the ingredients we avoid. 

  • Sodium Lauryl Sulfate

We do not use SLS (short for Sodium Lauryl Sulfate), which is a common component of ordinary toothpastes. This chemical compound does not actually clean teeth—its sole purpose is to produce foam, which only gives the impression of cleaning.  In some people, it can cause skin irritation.

  •  Fluoride 

We do not add fluoride, although it is used in many commercial toothpastes. 

  • Artificial Colours 

Because we do not add artificial colours, the appearance of our products may vary from batch to batch.

  • Artificial Flavours or Fragrances 

We do not use any synthetic flavours or fragrances—we prefer a fresh, natural taste and are sure you will, too!

  • Artificial Preservatives (EDTA, Formaldehyde, Parabens, Etc.) 

Natural preservatives work as well, if not better, than artificial alternatives.

  • Animal Ingredients 

Our support of non-animal-testing models also includes the belief that we don't need to use animal ingredients to create effective products. For example, glycerin used in toothpastes and soaps is often made from animal ingredients, but ours is vegetable-based.

  • Saccharin Or Other Artificial Sweeteners  

Many conventional toothpastes contain artificial sweeteners. In Grin Natural toothpaste, we rely on the natural sweetness of xylitol, spearmint and fennel.
