So far I love the fresh and clean feeling I get with this toothpaste. I love that it’s non-toxic. I even pair it with a boar bristle wooden toothbrush to keep all of the micro plastics out of my system. My younger daughter who is 7 started using it and she says it’s not too minty for her but it definitely freshens your breath and whitens teeth well, keeps cavities away.
