Yogi Tooth Serum keeps mouths extremely fresh and clean. Ancient vedic botanicals offer anti-bacterial, anti-viral, and anti-fungal benefits for oral care. Neem alkalizes the gums and mouth, plus it helps kill bad breath bacteria. With ingredients like organic neem, cinnamon, clove, mastic, cayenne, and cardamom, only a drop or two is needed to keep the mouth healthy. It can also be massaged into gums or added to dental floss.
