A mineral form of calcium phosphate that contains fluorine, the main component of tooth enamel and bone.
From fluor- + apatite (phosphate mineral). This compound is naturally present in teeth and bones, providing strength and resistance to decay.
Your teeth literally contain fluorapatite crystals, and when you use fluoride toothpaste, you're helping build even more of this mineral to protect against cavities—it's your body's own armor!
