Is nano hydroxyapatite the breakthrough your teeth have been waiting for—or just another viral myth in oral care?

In this episode of Dental Formulator's Playbook, Dr. Rob and Tami tackle the growing buzz around nano hydroxyapatite (nano HAP) — a trending ingredient in oral care products. They break down the science behind nano HAP, separating fact from fiction, and address viral claims that it can instantly repair or whiten teeth. Dr. Rob explains what remineralization really means, why fluoride remains the gold standard for enamel protection, and where nano HAP fits into the conversation. From potential use for sensitivity relief or targeted use in children’s toothpaste, the hosts explore nano HAP’s possibilities and limits — and preview a deeper dive into specific nano HAP products in future episodes.
