Black Toenail â Causes, Treatment, and Prevention. There are many causes of black or dark toenails, but the most common cause is trauma. When trauma occurs to a nail resulting in discoloration it is referred to as a subungual hematoma, which simply means there is a collection of blood underneath the nail.
The infection is generally located underneath the nail. A toenail fungus infection can cause foul smells and discoloration. The fungus that grows under the nail eats keratin, the protein that makes our nails strong and hard.
