This is an Oak bark based tooth powder to use as an additive to your usual routine or to make a little poultice and place on the gums. It is a lovely blend of clay, oak bark, clove and astringent black walnut amongst other herb to settle and soothe. I love these blends that have been in use for a long time. I add this to my gentle toothpaste a couple times a week or as needed on gums.
