Question

Fluoride is actually well absorbed, mostly in the stomach and proximal intestine. This makes statement A false. Calcium-containing foods can indeed decrease fluoride absorption, fluoride does form fluorhydroxyapatite in tooth enamel which helps in preventing cavities, and fluoride's effect on cavity prevention is indeed greatest during childhood, making the other statements true.
