Purified water is an ingredient in our toothpaste however we recommend the use of tap water whenever possible when mixing with Periogen Oral Rinse concentrate powder. Tap water usually contains a variety of healthy minerals like calcium and magnesium since it travels through rock formations. Tap water is most likely to contain fluoride either naturally or as an added mineral. Fluoride is beneficial for healthy teeth and bones.
