Natural HydroxyapatiteDon’t let that scientific name fool you - hydroxyapatite is a naturally occuring mineral form of calcium apatite and is actually the main mineral that our dental enamel is made of. Hydroxyapatite is the best alternative to fluoride and has been proven to provide the necessary minerals to remineralise subsurface areas of the tooth, restoring the enamel to its near natural state, without changing the composition of the enamel. |

Organic Sea SaltEver wondered why dentists suggest rinsing with saltwater after a dental procedure? The alkaline nature of sea salt increases the pH balance of your mouth, creating an environment that bacteria really, really hate. The sea salt we’ve put in Grin is certified organic, so it retains more of the good stuff such as calcium, magnesium, silicon, phosphorus and iron. |
Concerned about the ingredients that go into the products you buy? We are too – that's why we like to share as much detail as possible with you, so that you can feel comfortable in choosing Grin!
