Depends on how many: If multiple fingernails have fallen off at once, it may be a sign of a serious problem and should be evaluated. If it's only one or two, it may be due to trauma or an accident long ago. Sometimes the nail will separate after getting hit or smashed, but may take some time to actually loosen up and fall off.
