flu·or·ap·a·tite

 (flo͞o′ôr-ăp′ə-tīt′, -ər-)
n.
A hard, variously colored apatite mineral, calcium fluoride phosphate, Ca5F(PO4)3, that is the most common phosphate mineral and is used in the manufacture of fertilizers. Fluorapatite is formed in tooth enamel exposed to fluoride and helps prevent decay by its resistance to acidity. Also called apatite.
