Hydroxyapatite Toothpaste: A Science-Based Alternative to Fluoride Hydroxyapatite Toothpaste: A Science-Based Alternative to Fluoride For decades, fluoride has dominated dental care conversations. But critical thinkers are increasingly examining hydroxyapatite—a naturally occurring mineral that comprises 97% of tooth enamel. The Science Behind Hydroxyapatite Unlike fluoride, which works by converting enamel to fluorapatite, hydroxyapatite directly replenishes the mineral structure teeth naturally lose through daily acid exposure. Japanese researchers pioneered its use in the 1970s, demonstrating comparable remineralization effects to fluoride without systemic absorption concerns. Why Consider the Switch? Hydroxyapatite offers remineralization benefits while being biocompatible and safe if swallowed—particularly relevant for families with young children. Studies show it effec...
