There’s one key ingredient that’s not in your toothpaste: Its called Hydroxyapatite.

HAP, a natural calcium form found in saliva, is the same material as your teeth. It helps repair and protect them by filling gaps and cracks, binding to the surface to make them stronger, less sensitive, and whiter.

Ollie uses the optimal particle size (nano) and concentration (10%) of Hydroxyapatite to rebuild enamel over time, resulting in stronger, whiter, and less sensitive teeth.
