Lost toenails grow back, of course, but it takes six months. (And if the injury has damaged the nail matrix, the new nail will be thicker.) Since injured nails often don't come off immediately, walking around with bruised, loose nails that you know are going to fall off (hopefully not in yoga class) is not much fun.
Similarly one may ask, do bruised toenails ever go away?
Since you have recently sustained trauma to your toenail, you develop a condition called hematoma, or blood under the nail, that causes a bruise. They can take a long time to clear up. Sometimes the black spot does not go away until it grows out with the nail.
What causes toenails to turn dark?
Melanoma: This is the most serious type of skin cancer, which often appears as a dark brown misshapen spot. Such spots can also occur underneath nail beds. Trauma: Usually caused by an injury, trauma to the toenail can cause the blood vessels beneath a nail to break.
What causes a toenail to turn black?
Fungal infections are another common problem that can cause black toenails to form. Typically, a fungal infection causes a white or yellowish discoloration. However, debris can build up near the infection, causing the nail to appear black.
