HAAN toothpastes are 96% natural and contain the premium ingredient hydroxyapatite (a non-toxic substitute for fluoride), which makes teeth stronger and brighter! But why is hydroxyapatite good for teeth? Hydroxyapatite is a form of calcium that makes up 97% of tooth enamel and 70% of dentin, or tooth bone. Hydroxyapatite strengthens tooth enamel, making your smile more beautiful and bright. If this substance is added to toothpaste, it helps: - remineralize the tooth enamel, filling the unevenness on the teeth - whiten teeth - prevent cavities - prevent tooth sensitivity In addition, hydroxyapatite is natural, so it is not toxic unlike fluoride.
