Hydroxyapatite

Hydroxyapatite is a naturally occurring mineral composed primarily of calcium and phosphate, and it is the principal mineral found in human teeth and bones as well as in the teeth and bones of many animals. Historically, scientists identified hydroxyapatite as the primary mineral responsible for the strength and structure of tooth enamel, leading to its development for dental and personal care applications in the 20th century. Today, naturally derived or biomimetic hydroxyapatite is widely used in all-natural toothpastes and oral care products, where it is valued as a mineral-based ingredient that supports clean, effective formulations.
