PurO3 Tooth & Gum Support is made from fully ozonated organic olive oil and ozonated organic hemp seed oil with your choice of flavors. There's no fluoride or extra ingredients. Also available in one ounce tubes. Recently, ozonated olive oil has been recommended by several well known health practitioners as an excellent support for teeth and gums, for plaque removal and for other uses. We combined it with a little ozonated hemp seed oil to make it even better. You can choose peppermint, peppermint, and Stevia, or cherry and Stevia.
