Scientists on their expedition to the Arctic found that the indigenous people had healthy, bright white teeth. But in the harsh environment, they do not have good oral care tools and habits.

Their only way to clean their mouth is to use a common local lichen to scrub their teeth. As the lichen grows in its harsh environment, it will produce many protective and defensive substances to maintain its survival.

So, scientists apply this rare plant to oral care products, so that it can continue to protect the health of teeth and oral cavity!
