Fluoride on teeth is a bit like making gorilla glass - infusing atoms into a surface with different bond strengths and lengths to make a material that’s more durable than the original.

I guess you could think of both as “alloys”, but with ionic bonds instead of metallic bonds.

I’m sure there are at least six ways this isn’t quite accurate, but it’s an interesting analogy at least.
