What do white spots on toenails mean?

White Spots on fingernails usually mean an injury to the nail bed, however some people believe it's to do with a zinc or calcium deficiency, which is a myth because it's not just on our hands we grow nails. If you have White Spots on your Toenails as well as your Fingernails then maybe your needing a vitamin supplement. On Fingernails only then most likely cause is an injury.

It could be the normal part of the nail called the lunula.
